light-emitting display panel. The liquid crystal organic
light-emitting display panel forms an electric field capable of
controlling a deflection of liquid crystal molecules by applying a
voltage on a pixel electrode and a common electrode, and thus
exerts the display function of the organic light-emitting display
panel by controlling the transmission of light. In contrast, the
organic self-luminous organic light-emitting display panel adopts
an organic electroluminescent material, and when electric current
passes through the organic electroluminescent material, the
luminescent material emits light, thereby exerting the display
function of the organic light-emitting display panel.
[0004] With the application of the display technology in smart
wearable devices and other portable electronic devices, the
electronic products are designed to constantly pursue performance
that can achieve the user-friendly experience and improve the

scope of the present disclosure.
[0028] The terms used in the embodiments of the present disclosure
are merely for the purpose of describing specific embodiments,
rather than limiting the present disclosure. The singular form "a",
"an", "the" and "said" used in the embodiments and claims shall be
interpreted as also including the plural form, unless indicated
otherwise in the context.
[0029] It should be understood that the term "and/or" used herein
is merely an association relationship describing associated
objects, indicating that there may be three relationships, for
example, A and/or B may indicate that three cases, i.e., A existing

power supply signal line, and a first pixel unit also can be
referred as a second display region, a second data line, a second
power supply signal line, and a second pixel unit, respectively,
and vice versa.
[0031] An organic light-emitting display panel 100 according to an
embodiment of the present disclosure, as shown in FIG. 1, includes
a hollow area 30 and a display area 20 surrounding the hollow area
30. The organic light-emitting display panel 100 further includes a
plurality of pixel units P, a plurality of gate lines G, and a
plurality of data lines D. Each data line D intersects with each
gate line G. Each data line D is insulated from each gate line
G.
[0032] Referring to FIG. 1, no pixel unit P is provided within the
hollow area 30, and the plurality of pixel units P is provided in
the periphery of the hollow area 30. That is, the hollow area 30
does not have a display function, and both sides of the hollow area
30 are transmissive due to the absence of the pixel units P, i.e.,
the hollow area 30 is visible when being viewed from any side of
the organic light-emitting display panel 100 to the other side. It
should be understood that, "no pixel unit P is provided in the
hollow area 30" means that neither an organic light-emitting
display component that blocks light transmission (i.e., an anode, a
light-emitting layer and a cathode) nor a pixel driving circuit
that drives the organic light-emitting display component to emit
light (i.e., a transistor and a capacitor) is provided in the
hollow area 30.
[0033] Referring to FIG. 1 again, the display area 20 includes a
full display area 200 and a half display area 210. The full display
area 200 includes a first display region 201, a second display
region 202, a third display region 203, a fourth display region
204, and a fifth display region 205. The first display region 201,
the hollow area 30 and the second display region 202 are
sequentially arranged along a first direction X. That is, on the
organic light-emitting display panel 100, along the first direction
X, the first display region 201, the hollow area 30 and the second
display region 202 are arranged in an order such that the hollow
area 30 is disposed between the first display region 201 and the
second display region 202. The half display area 210, the hollow
area 30, and the third display region 203 are sequentially arranged
along a second direction Y. That is, on the organic light-emitting
display panel 100, along the second direction Y, the half display
area 210, the hollow area 30 and the third display region 203 are
arranged in an order such that the hollow area 30 is disposed
between the half display area 210 and the third display region 203.
As shown in FIG. 1, the half display area 210, the first display
region 201, the second display region 202, the third display region
203, the fourth display region 204 and the fifth display region 205
are arranged around the hollow area 30.
[0034] Referring to FIGS. 1 and 2, the plurality of pixel units P
includes first pixel units P1 and second pixel units P2. The first
pixel units P1 are located only in the full display area 200, and
the second pixel units P2 are located only in the half display area
210. A number of the first pixel units P1 per unit area Ave of the
full display area 200 is greater than a number of the second pixel
units P2 per unit area Ave of the half display area 210. It should
be understood that the unit area Ave can be 1 cm.sup.2 or other
reference areas, as long as a same area of the full display area
200 and the half display area 210 is selected to compare the number
of the first pixel units P1 per unit area Ave of the full display
area 200 and the number of the second pixel units P2 per unit area
Ave of the half display area 210. FIG. 2 only illustrates a manner
of selecting the unit area Ave, in which more than 6 first pixel
units P1 are located in one unit area Ave of the full display area
200, and 4 second pixel units P2 are located in one unit area Ave
of the half display area 210. That is, in the unit area Ave, the
number of the first pixel units P1 is greater than the number of
the second pixel units P2.
[0035] In the organic light-emitting display panel 100 provided by
the embodiment of the present disclosure, the hollow area 30, the
half display area 210 and the full display area 200 surrounding the
hollow area 30 are provided, and the number of the pixel units P
per unit area Ave of the full display area 200 is larger than the
number of the pixel units P per unit area Ave of the half display
area 210. In this way, it is possible in the organic light-emitting
display panel 100 that not only an independent sensor module or
acquisition module can be provided in the hollow area 30, but a
sensing unit located in the organic light-emitting display panel
100 can be integrated in the half display area 210 and serve to
display. Therefore, a ratio of a displayable area of the organic
light-emitting display panel 100 to a total area of the organic
light-emitting display panel 100 is increased, which can improve
the user experience.
[0036] According to another embodiment of the present disclosure,
as shown in FIG. 3, the organic light-emitting display panel 100
further includes a first gate driving unit Q1 and a second gate
driving unit Q2. The first gate driving unit Q1, the first display
region 201, the hollow area 30, the second display region 202, and
the second gate driving unit Q2 are sequentially arranged in the
first direction X. That is, in the first direction X, the first
gate driving unit Q1, the first display region 201, the hollow area
30, the second display region 202, and the second gate driving unit
Q2 are arranged in an order such that the first gate driving unit
Q1 is located at a side of the first display region 201 away from
the hollow area 360 and the second gate driving unit Q2 is located
at a side of the second display region 202 away from the hollow
area 30.
[0037] Referring to FIG. 3, the pixel units P located in the first
display region 201 are electrically connected to the first gate
driving unit Q1 and are insulated from the second gate driving unit
Q2. The pixel units P located in the second display region 202 are
electrically connected to the second gate driving unit Q2 and are
insulated from the first gate driving unit Q1. That is, the pixel
units at one side of the hollow area 30 are separated by the hollow
area 30 from those at the other side, and the pixel units at each
side are driven separately. In other words, no gate driving unit is
arranged between the hollow area 30 and the first display region
201 to drive the pixel units P in the first display region 201, and
no gate driving unit is arranged between the hollow area 30 and the
second display region 202 to drive the pixel units P in the second
display region 202.
[0038] Still referring to FIG. 3, the organic light-emitting
display panel 100 further includes first gate lines G1 located in
the first display region 201 and second gate lines G2 located in
the second display region 202. The hollow area 30 is located
between the first gate lines G1 and the second gate lines G2 so as
to insulate the first gate lines G1 from the second gate lines G2.
Each first gate line G1 has a first end electrically connected to
the first gate driving unit Q1, and a second end insulated from the
second ends of other first gate lines G1. Each second gate line G2
has a first end electrically connected to the second gate driving
unit Q2, and a second end insulated from the second ends of other
second gate lines G2. That is, the gate lines at one side of the
hollow area 30 are separated by the hollow area 30 from those at
the other side, and the gate lines at each side are driven
separately. In other words, no gate driving unit is arranged
between the hollow area 30 and the first display region 201 for
electrically connecting to the first gate lines G1, and no gate
driving unit is arranged between the hollow area 30 and the second
display region 202 for electrically connecting to the second gate
lines G2.
[0039] In the organic light-emitting display panel 100 provided by
the embodiment of the disclosure, the pixel units at each side of
the two sides of the hollow area 30 are driven separately, so that
the gate driving unit at the other side of the first display region
201 and the gate driving unit at the other side of the second
display region 202 can be omitted. In this way, width of frame at
both sides of the hollow area 30 can be reduced, so as to form a
narrow frame of the hollow area 30 and thus increase a
screen-to-body ratio. In addition, since a number of pixel units in
regions at both sides of the hollow area 20 is smaller than a
number of pixel units arranged in rows along the first direction in
the other regions, the driving capability of the organic
light-emitting display panel 100 will not be affected by the
single-side driving. Therefore, the organic light-emitting display
panel 100 according to the embodiment of the present disclosure can
achieve a narrow frame under the premise of ensuring the driving
capability.
[0040] Further referring to FIG. 3, the organic light-emitting
display panel 100 further includes a third gate driving unit Q3, a
fourth gate driving unit Q4, a fifth gate driving unit Q5, and a
sixth gate driving unit Q6.
[0041] The third gate driving unit Q3, the third display region
203, and the fourth gate driving unit Q4 are sequentially arranged
along the first direction X. That is, in the first direction X, the
third gate driving unit Q3, the third display region 203, and the
fourth gate driving unit Q4 are arranged in an order such that the
third display region 203 is located between the third gate driving
unit Q3 and the fourth gate driving units Q4. The pixel units P
located in the third display region 203 are electrically connected
to both the third gate driving unit Q3 and the fourth gate driving
unit Q4. In other words, the pixel units P in the third display
region 203 are driven at two sides.
[0042] The fifth gate driving unit Q5, the fourth display region
204, the half display area 210, the fifth display region 205 and
the sixth gate driving unit Q6 are sequentially arranged along the
first direction X. That is, in the first direction X, the fifth
gate driving unit Q5, the fourth display region 204, the half
display area 210, the fifth display region 205 and the sixth gate
driving unit Q6 are arranged in an order such the fifth gate
driving unit Q5 is located at a side of the fourth display region
204 away from the half display area 210, and the sixth gate driving
unit Q6 is located at a side of the fifth display region 205 away
from the half display area 210. The pixel units P located in the
fourth display region 204, the half display area 210 and the fifth
display region 205 are electrically connected to both the fifth
gate driving unit Q5 and the sixth gate driving unit Q6. In other
words, the pixel units P in the fourth display region 204, the half
display area 210 and the fifth display region 205 are driven at two
sides.
[0043] Further referring FIG. 3, the organic light-emitting display
panel 100 further includes third gate lines G3 located in the third
display region 203 and fourth gate lines G4.
[0044] Each third gate line G3 has a first end electrically
connected to the third gate driving unit Q3, and a second end
electrically connected to the fourth gate driving unit Q4. That is,
the third gate lines G3 located in the third display region 203 are
electrically connected to the pixel units P of the in the third
display region 203, and driven at two sides.
[0045] Along the first direction X, the fourth gate lines G4 extend
from the fourth display region 204 to the fifth display region 205
through the half display area 210. Each fourth gate line G4 has a
first end electrically connected to the fifth gate driving unit Q5,
and a second end electrically connected to the sixth gate driving
unit Q6. That is, the fourth gate lines G4 extend over the fourth
display region 204, the half display area 210 and the fifth display
region 205, and are electrically connected to the pixel units P
located therein and driven at two ends.
[0046] As shown in FIG. 3, the third display region 203 is located
on a side of the first display region 201, the hollow area 30 and
the second display region 202, and is not split by the hollow area
30. The pixels units P located in the third display region 203 are
arranged in an entire row in the first direction X, and the number
of the pixel units P in the third display region 203 is larger. The
two-side driving can improve the driving capability of the organic
light-emitting display panel 100, the response speed of the third
display region 203, and the user experience. Similarly, the fourth
display region 204, the half display area 210, and the fifth
display region 205 are not split by the hollow area 30. The pixel
units P located therein are arranged in an entire row in the first
direction X. The number of pixel units P located in the fourth
display region 204, the half display area 210 and the fifth display
region 205 is smaller than that in the third display region 203,
due to the decreased number of pixel units P in the half display
area 210. However, the presence of the first gate driving unit Q1
and the second gate driving unit Q2 at both sides of the display
area reserves space for the fifth gate driving unit Q5 and the
sixth gate driving unit Q6 to be arranged above the first gate
driving unit Q1 and the second gate driving unit Q2, respectively,
so as to drive the pixel units P in the fourth display region 204,
the half display area 210 and the fifth display region 205 at two
side, without additionally occupying more space of the frame.
[0047] Therefore, the organic light-emitting display panel 100
according to the embodiment of the present disclosure can
effectively utilize the frame region to perform single-side driving
and two-side driving in different regions, thereby reducing the
width of the frame on both sides of the hollow area 30 and
improving the driving capability and response speed of the organic
light-emitting display panel 100 and the user experience.
[0048] Referring to FIG. 1 and FIG. 4, one pixel unit P of the
organic light-emitting display panel 100 includes a pixel driving
circuit, a gate line G configured to provide scan signals SCAN1 and
SCAN2 to the pixel driving circuit, and a data line D configured to
provide a data signal DATA to the pixel driving circuit. The
organic light-emitting display panel may further include a power
supply signal line and a light emission control line. The power
supply signal line provides a power supply signal PVDD to the pixel
driving circuit, and the light emission control line provides a
light emission control signal EMIT to the pixel driving circuit.
FIG. 4 merely shows one of the pixel driving circuits of the
organic light-emitting display panel 100 according to an embodiment
of the present disclosure. In other embodiments of the present
disclosure, the pixel driving circuit may also adopt other layouts
and driving modes, as long as the pixel driving circuit can drive
the light-emitting elements to emit light by using the scan signals
SCAN1 and SCAN2 provided by the gate line G, the data signal DATA
provided by the data line D, the power supply signal PVDD provided
by the power supply signal line, and the light emission control
signal EMIT provided by the light emission control line.
[0049] As an example, FIG. 4 illustrates a layout and driving mode
of the pixel driving circuit of the pixel unit P. The pixel driving
circuit of the organic light-emitting display panel 100 according
to the embodiment of the present disclosure includes first to
seventh transistors M1 to M7.
[0050] The first transistor M1 is configured to transmit the data
signal DATA in response to the first scan signal SCAN1. The second
transistor M2 is configured to generate a driving current I under
control of the data signal DATA transmitted through the first
transistor M1. The third transistor M3 is configured to detect and
self-compensate a threshold voltage deviation of the second
transistor M2. The fourth transistor M4 is configured to transmit
the power supply signal VDD to the second transistor M2 in response
to the light emission control signal EMIT. The fifth transistor M5
is configured to transmit the driving current I generated by the
second transistor M2 to the light-emitting element D in response to
the light emission control signal EMIT, and the light-emitting
element D is configured to emit light under control of the driving
current I. The sixth transistor M6 is configured to transmit a
signal having a first potential V1 to the light-emitting element D
in response to the second scan signal SCAN2. The seventh transistor
M7 is configured to transmit a signal having a second potential V2
to a gate of the second transistor M2 in response to the second
scan signal SCAN2.
[0051] Referring to FIG. 1 and FIG. 5, the pixel units P of the
organic light-emitting display panel 100 according to an embodiment
of the present disclosure include first pixel units P1 and second
pixel units P2. The first pixel units P1 are located in the full
display area 200, and the second pixel units P2 are located in the
half display area 210. A length a1 of the first pixel unit P1 in
the first direction X is smaller than a length a2 of the second
pixel unit P2 in the first direction X.
[0052] In addition, a width b1 of the first pixel unit P1 in the
second direction Y is equal to a width b2 of the second pixel unit
P2 in the second direction Y.
[0053] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, by setting the width b1
of the first pixel unit P1 in the second direction Y and the width
b2 of the second pixel unit P2 in the second direction Y to be
equal, a same row of the pixel units P located in the fourth
display region 204, the fifth display region 205 and the half
display area 210 can be electrically connected to a same gate line
G. In this way, the gate lines G can be easily arranged, without
being bent or winded, such that the gate lines G in the fourth
display region 204, the fifth display region 205 and the half
display area 210 have a same driving capability as the gate lines G
in the third display region 203, thereby ensuring an uniformity of
the organic light-emitting display panel.
[0054] Further, referring to FIG. 1 and FIG. 6, the first pixel
unit P1 includes a first pixel circuit region Px. The first pixel
circuit region Px1 shown in FIG. 6 occupies the entire first pixel
unit P1, i.e., the entire area of the first pixel unit P1 is used
to arrange the pixel driving circuit. In other words, the first
pixel circuit region Px1 has a same area as the first pixel unit
P1. The second pixel unit P2 includes a blank region Pb and a
second pixel circuit region Px2, i.e., the second pixel circuit
region Px2 does not completely occupy the entire second pixel unit
P2. In other words, the second pixel unit P2 is configured to have
a blank region Pb in which no pixel driving circuit is provided.
The second pixel circuit region Px2 has a smaller area than the
second pixel unit P2. A length a21 of the second pixel circuit
region Px2 in the first direction X is equal to a length a1 of the
first pixel circuit region Px1 in the first direction X.
[0055] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, by setting the length a21
of the second pixel circuit region Px2 in the first direction X to
be equal to the length a1 of the first pixel circuit region Px1 in
the first direction X, pixel driving circuits of the first pixel
unit P1 and the second pixel unit P2 can adopt same parameters, so
that an aspect ratio of the transistor and consistency between
regions where the transistor and the capacitor are located
respectively are increased. In this way, the driving capability of
the pixel driving circuits of the first pixel unit P1 and the
second pixel unit P2 can be ensure to be uniform, thereby
increasing the uniformity of the organic light-emitting display
panel 100.
[0056] Further, referring to FIG. 1 and FIG. 5, the ratio of the
length a1 of the first pixel unit P1 in the first direction X to
the length a2 of the second pixel unit P2 in the first direction X
is 1:2. That is, the length a2 of the second pixel unit P2 in the
first direction X is twice the length a1 of the first pixel unit P1
in the first direction X. Referring to FIG. 1 and FIG. 6, a length
a22 of the blank region Pb in the first direction X and the length
a21 of the second pixel circuit region Px2 in the first direction X
are both equal to the length a1 of the first pixel circuit region
Px1 in the first direction X. That is, the length a21 of the second
pixel circuit region Px2 of the second pixel unit P2 in the first
direction X, the length a22 of the blank region Pb of the second
pixel unit P2 in the first direction X, and the length a1 of the
first pixel unit P1 in the first direction X satisfy
a21:a22:a1=1:1:1.
[0057] The organic light-emitting display panel 100 according to
the embodiment of the present disclosure, as shown in FIG. 1, FIG.
4 and FIG. 7, further includes first data lines D1, second data
lines D2, first power supply signal lines PVDD1 and second power
supply signal lines PVDD2.
[0058] The first data lines D1 and the first power supply signal
lines PVDD1 are located in the full display area 200, i.e., the
first data lines D1 and the first power supply signal lines PVDD1
are electrically connected to the first pixel units P1 and
configured to provide the data signal DATA and the power supply
signal PVDD to the first pixel units P1.
[0059] The second data lines D2 and the second power supply signal
lines PVDD2 are located in the half display area 210, i.e., the
second data lines D2 and the second power supply signal lines PVDD2
are electrically connected to the second pixel units P2 and
configured to provide the data signal DATA and the power supply
signal PVDD to the second pixel units P2.
[0060] FIG. 7 shows layouts of pixel driving circuits of the first
pixel units P1 and the second pixel unit P2 in the organic
light-emitting display panel 100. In other embodiments of the
present disclosure, the pixel driving circuits of the first pixel
units P1 and the second pixel unit P2 may also adopt other layouts
and driving modes.
[0061] As shown in FIG. 7, a length of the first data line D1 in
the first direction X is equal to a length of the second data line
D2 in the first direction X. A length of the first power supply
signal line PVDD1 in the first direction X is equal to a length of
the second power supply signal line PVDD2 in the first direction
X.
[0062] As shown in FIG. 7, a pixel driving circuit capable of
driving the first pixel units P1 is provided in a region between
two adjacent first data lines D1, which the region can be referred
as a first pixel circuit region Px1. In FIG. 7, the first pixel
circuit region Px1 has a length a1 in the first direction X.
Another pixel driving circuit capable of driving the second pixel
units P2 is provided in a region between two adjacent second data
lines D2, which the region can be referred as a second pixel
circuit region Px2. In FIG. 7, the second pixel circuit region Px2
has a length a21 in the first direction X. The length a1 of the
first pixel circuit region Px1 in the first direction X is equal to
the length a21 of the second pixel circuit region Px2 in the first
direction X. As shown in FIG. 7, the second pixel unit P2 further
includes a blank region Pb which is a circuit element of the pixel
driving circuit, such as a transistor and a capacitor. The blank
region Pb has a greater light transmittance than the second pixel
circuit region Px2. Since the second pixel unit P2 has the blank
region Pb, the second pixel unit P2 has a greater light
transmittance than the first pixel unit P1. That is, the half
display area 210 has a greater light transmittance per unit area
than the full display area 200.
[0063] As shown in FIG. 8, the organic light-emitting display panel
100 further includes a sensor 50 located in the half display area
210. The sensor 50 can be a light-sensing fingerprint unit that
detects and recognizes a fingerprint using a change in light, and
performs unlocking, quick payment, or other operations on the
organic light-emitting display panel 100. The sensor 50 may also be
a panel recognition unit configured to collect facial information
and perform unlocking, quick payment or other operations on the
organic light-emitting display panel 100. The sensor 50 may also be
a light sensor or a distance sensor configured to detect a distance
of a human body or an object from the organic light-emitting
display panel 100, and switch between a display mode and a
non-display mode in the organic light-emitting display panel
100.
[0064] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, the second pixel units P2
in the half display area 210 each includes the blank region Pb,
such that the light transmittance of the half display area 210 is
increased, and the sensor is disposed in the half display area 210,
such that the half display area 210 has functions of display and
sensing control at the same time. This can improve the
screen-to-body ratio of the organic light-emitting display panel
100, optimize the additional performance of the organic
light-emitting display panel 100 and satisfy the diverse
requirements from users.
[0065] An embodiment of the present disclosure further provides an
organic light-emitting display panel 100, as shown in FIGS. 1 and
9. The pixel units P include first pixel units P1 located in the
full display area 200 and second pixel units P2 located in the half
display area 210.
[0066] As shown in FIG. 9, a distance n1 between two adjacent first
pixel units P1 in the first direction X is smaller than a distance
n2 between two adjacent second pixel units P2 in the first
direction X. In addition, a distance ml between two adjacent first
pixel units P1 in the second direction Y is also smaller than a
distance m2 between two adjacent second pixel units P2 in the
second direction Y. That is, in the organic light-emitting display
panel 100 according to the embodiment of the present disclosure,
the distance between two adjacent first pixels P1 and the distance
between two adjacent second pixel units P2 satisfy at least one of
the following relationships: n1<n2 and m1<m2.
[0067] Referring to FIG. 1, FIG. 4 and FIG. 10, the organic
light-emitting display panel 100 further includes first data lines
D1, second data lines D2, first power supply signal lines PVDD1 and
second power supply signal lines PVDD2.
[0068] The first data lines D1 and the first power supply signal
lines PVDD1 are located in the full display area 200, i.e., the
first data lines D1 and the first power supply signal lines PVDD1
are electrically connected to the first pixel units P1 and
configured to respectively provide the data signal DATA and the
power supply signal PVDD to the first pixel units P1.
[0069] The second data lines D2 and the second power supply signal
lines PVDD2 are located in the half display area 210, i.e., the
second data lines D2 and the second power supply signal lines PVDD2
are electrically connected to the second pixel units P2 and
configured to respectively provide the data signal DATA and the
power supply signal PVDD to the second pixel units P2.
[0070] FIG. 10 shows layouts of pixel driving circuits of the first
pixel units P1 and the second pixel unit P2 in the organic
light-emitting display panel 100. In other embodiments of the
present disclosure, the pixel driving circuits of the first pixel
units P1 and the second pixel unit P2 may also adopt other layouts
and driving modes.
[0071] As shown in FIG. 10, a length of the first data line D1 in
the first direction X is smaller than a length of the second data
line D2 in the first direction X. A length of the first power
supply signal line PVDD1 in the first direction X is smaller than a
length of the second power supply signal line PVDD2 in the first
direction X. FIG. 10 merely illustrates a case in which the length
of the first data line D1 in the first direction X and length of
the first power supply signal line PVDD1 in the first direction X
are respectively smaller than the length of the second data line D2
in the first direction X and the length of the second power supply
signal line PVDD2 in the first direction. However, in other
embodiments of the present disclosure, it is only necessary to
satisfy one of the following two relationships: the length of the
first data line D1 in the first direction X is smaller than the
length of the second data line D2 in the first direction X; and the
length of the first power supply signal line PVDD1 in the first
direction X is smaller than the length of the second power supply
signal line PVDD2 in the first direction X.
[0072] As shown in FIG. 10, a pixel driving circuit capable of
driving the first pixel unit P1 is provided in a region between two
adjacent first data lines D1, which the region can be understand as
the first pixel unit P1. A distance between two adjacent first
pixel units P1 in the first direction X is n1.
[0073] As shown in FIG. 10, a pixel driving circuit capable of
driving the second pixel unit P2 is provided in a region between
two adjacent second data lines D2, which the region can be
understand as the second pixel unit P2. A distance between two
adjacent second pixel units P2 in the first direction X is n2.
[0074] The distance n2 between two adjacent second pixel units P2
in the first direction X is greater than the distance n1 between
two adjacent first pixel units P1 in the first direction X is, such
that there is space for setting a width of the second data lines D2
to be larger than a width of the first data lines D1 and a width of
the second power supply signal line PVDD2 to be larger than a width
of the first power supply signal line PVDD1.
[0075] Referring to FIG. 11 and FIG. 10, since the second data line
D2 is split by the hollow area 30, it is impossible for the second
data line D2 to extend to a lower region of the frame along the
second direction Y. Therefore, the organic light-emitting display
panel 100 according to the embodiment of the present disclosure may
further include a data connection line L, the data connection line
L is disposed around the hollow area 30. The second data line D2
electrically connected to the second pixel unit P2 is electrically
connected to the first data line D1 electrically connected to the
first pixel unit P1 through the data connection line L.
[0076] Further referring to FIG. 11, an extension line of the
second data line D2 overlaps with the first data line D1 that is
electrically connected to the second data line D2 through the data
connection line L. That is, the second data line D2 and the first
data line D1 electrically connected to each other through the data
connection line L are located in a same column along the second
direction Y
[0077] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, by setting the distance
between two adjacent second pixel units P2 to be greater than the
distance between two adjacent first pixel units P1, a width of the
second data lines D2 and/or a width of the second power supply
signal line PVDD2 in the first direction X can be increased. In
this way, a resistance of the second data line D2 and/or a
resistance of the second power supply signal line PVDD2 is reduced
due to the winding, so that electrical signal losses of the first
data line D1 and the second data line D2 tend to be same, which can
enhance the uniformity of the organic light-emitting display panel
100 according to the embodiment of the present disclosure.
[0078] Another embodiment of the present disclosure provides an
organic light-emitting display panel 100, as shown in FIG. 12. The
half display area 210 is rectangular, and a length E of the half
display area 210 in the first direction X is equal to a length F of
the hollow area 30 in the direction X.
[0079] With reference to FIG. 12, the display area 20 of the
organic light-emitting display panel 100 is in a rectangular shape,
and the four sides of the hollow area 30 are parallel to the four
sides of the display area 20, respectively. A first side, a second
side, a third side and a fourth side of the hollow area 30 are
connected in the rectangular shape in a counterclockwise direction.
A first side, a second side, a third side and a fourth side of the
display area 20 are connected in the rectangular shape in a
counterclockwise direction.
[0080] A distance between the first side of the hollow area 30 and
the first side of the display area 20 is the minimum distance from
the hollow area 30 to the display area 20.
[0081] Four sides of the hollow area 30 respectively extend to
three sides of the display area 20 to obtain respective extension
lines. The half display area 210 is formed by the first side of the
hollow area 30, the first side of the display area 20, the
extension line of the second side of the hollow area 30 and the
extension line of the fourth side of the hollow area 30.
[0082] The first display region 201 is formed by the second side of
the hollow area 30, the second side of the display area 20, the
extension line of the first side of the hollow area 30, and the
extension line of the third side of the hollow area 30.
[0083] The second display region 202 is formed by the fourth side
of the hollow area 30, the fourth side of the display area 20, the
extension line of the first side of the hollow area 30, and the
extension line of the third side of the hollow area 30.
[0084] The third display region 203 is formed by the second side of
the display area 20, the third side of the display area 20, the
fourth side of the display area 20, and the extension line of the
third side of the hollow area 30.
[0085] The fourth display region 204 is formed by the first side of
the display area 20, the second side of the display area 20, the
extension line of the first side of the hollow area 30, and the
extension line of the second side of the hollow area 30.
[0086] The fifth display region 205 is formed by the first side of
the display area 20, the fourth side of the display area 20, the
extension line of the first side of the hollow area 30, and the
extension line of the fourth side of the hollow area 30.
[0087] Another embodiment of the present disclosure provides an
organic light-emitting display panel 100, as shown in FIG. 13. The
hollow area 30 is in a round shape, and a length E of the half
display area 210 in the first direction X is equal to a diameter F
of the hollow area 30. A first side, a second side, a third side
and a fourth side of the display area 20 are connected in a
rectangular shape in a counterclockwise direction.
[0088] With reference to FIG. 13, when the hollow area 30 is round,
four tangent lines of the round hollow area 30 are a tangent line
made through a point closest to the first side of the display area
20 on the perimeter of the hollow area 30, a tangent line made
through a point farthest from the first side of the display area 20
on the perimeter of the hollow area 30, a tangent line made through
a point closest to the second side of the display area 20 on the
perimeter of the hollow area 30, and a tangent line made through a
point farthest from the second side of the display area 20 on the
perimeter of the hollow area 30. The above four tangent lines of
the hollow area 30 and the sides of the display area 20
respectively form the half display area 210, the first display
region 201, the second display region 202, the third display region
203, the fourth display region 204, and the fifth display region
205, which will not repeated herein.
[0089] Another embodiment of the present disclosure provides an
organic light-emitting display panel 100, as shown in FIG. 14. The
hollow area 30 is in an oval shape, and a length E of the half
display area 210 in the first direction X is equal to a length of
the hollow area 30 in the direction X. A first side, a second side,
a third side and a fourth side of the display area 20 are connected
in a rectangular shape in a counterclockwise direction. When the
major or minor axis of the hollow area 30 is parallel to one side
of the display area 20, the length E of the half display area 210
in the first direction X is a length of the major or minor axis of
the hollow area 30.
[0090] With reference to FIG. 14, when the hollow area 30 is oval,
four tangent lines of the oval hollow area 30 are tangent lines
made through ends of the major and minor axes of the hollow area
30. The four tangent lines of the hollow area 30 and the sides of
the display area 20 respectively form the half display area 210,
the first display region 201, the second display region 202, the
third display region 203, the fourth display region 204, and the
fifth display region 205, which will not repeated herein.
[0091] In the organic light-emitting display panel 100 according to
the embodiments of the present disclosure, the half display area
210 is arranged based on the shape and positional relationship
between the hollow area 30 and the display area 20, so as to avoid
arranging the half display area 210 in a visually sensitive region.
In this way, the number of pixel units P per unit area of the half
display area 210 can be reduced to arrange a sensor or perform
uniformity of resistance, so that the user's visual experience can
be optimized while the screen-to-body ratio of the organic
light-emitting display panel 100 can be increased.
[0092] An embodiment of the present disclosure further provides an
organic light-emitting display panel 100, as shown in FIG. 1 and
FIG. 15. The organic light-emitting display panel 100 further
includes a substrate 40, and gate lines G, data lines D, and pixel
units P are disposed on the substrate 40. Each pixel unit P is
provided with a pixel driving circuit and a light-emitting element.
The light-emitting element includes a cathode, an anode, and a
light-emitting layer arranged between the cathode and the
anode.
[0093] With reference to FIGS. 1 and 15, the substrate 40 has a
hollow portion 401, which is a through-hole provided in the
substrate 40. The hollow portion 401 overlaps with the hollow area
30 such that light can go through the hollow area 30 and the hollow
portion 401 from either side of the organic light-emitting display
panel 100 to the other side. There is no substrate 40 at the hollow
portion 401, and the hollow area 30 is not provided with any
circuit element of the pixel unit P, the gate line G, and the data
line D. A through-hole is formed in the entire organic
light-emitting display panel 100 in the hollow area 30.
[0094] Further, the periphery of the hollow area 30 should be
packaged to prevent water or oxygen from entering the inside of the
organic light-emitting display panel 100, and the organic
light-emitting display panel 100 further includes a package device
48. The package device 48 can be an inorganic layer, an organic
layer, or a multilayer film package of inorganic layers. The
package device 48 also can be formed by disposing a package metal
on the substrate 40, coating with lass paste and performing a laser
melting encapsulation. Since the display area 20 of the organic
light-emitting display panel 100 includes the pixel units, the
organic light-emitting display panel 100 can emit light to a side
away from the substrate 40 in the display area 20, but light cannot
penetrate the substrate 40.
[0095] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, since the substrate 40 is
provided with the hollow portion 401 overlapping with the hollow
area 30, the organic light-emitting display panel 100 has a
through-hole in the hollow area 30, in which a sensing or
acquisition device, such as image acquisition device or earpiece,
can be embedded into the interior of the organic light-emitting
display panel 100, thereby reducing the thickness of the organic
light-emitting display panel 100.
[0096] An embodiment of the present disclosure further provides an
organic light-emitting display panel 100, as shown in FIG. 1 and
FIG. 16. The organic light-emitting display panel 100 further
includes a substrate 40, a plurality of gate lines G, a plurality
of data lines D, and a plurality of pixel units P disposed on the
substrate 40. The hollow area 30 is covered by the substrate 40. No
pixel unit P is provided in the hollow area 30. However, the gate
line G, the data line D, or other organic layer and insulation
layer can be provided in the hollow area 30 according the practical
requirement. The hollow area 30 is a transparent region such that
light can go through the hollow area 30 from either side of the
organic light-emitting display panel 100 to the other side.
[0097] The hollow region 30 is already sealed due to the complete
substrate 40 of the organic light-emitting display panel 100, so
that package parts at the periphery of the hollow area 30 are
unnecessary. It is only needed to provide package parts 48 at the
periphery of the organic light-emitting display panel 100. The
package device 48 can be an inorganic layer, an organic layer, or a
multilayer film package of inorganic layers. The package part 48
also can be formed by disposing a package metal on the substrate
40, coating with lass paste and performing a laser melting
encapsulation. Since the display area 20 of the organic
light-emitting display panel 100 includes the pixel units, the
organic light-emitting display panel 100 can emit light to a side
away from the substrate 40 in the display area 20, but light cannot
penetrate the substrate 40.
[0098] In the organic light-emitting display panel 100 according to
the embodiment of the present disclosure, by providing the complete
substrate 40 and the transparent hollow area 30, the organic
light-emitting display panel 100 has a virtual hole in the hollow
area 30, in which a sensing or acquisition device, such as image
acquisition device or earpiece, can be arranged at the outside of
the substrate 40 of the organic light-emitting display panel 100
but in correspondence to the hollow region 30. In this way,
packaging the hollow area 30 can be avoided, so as simplify the
process. In the meantime, the area to be sealed of the organic
light-emitting display panel 100 can be also reduced, such that the
water or oxygen can be further prevented from entering, and thus
the service life of the organic light-emitting display panel 100
can be prolonged.
[0099] An embodiment of the present disclosure further provides an
organic light-emitting display device 500, as shown in FIG. 17,
which includes the organic light-emitting display panel 100
according to any one of the embodiments of the present disclosure.
The organic light-emitting display device 500 further includes an
image acquisition device 60 or a sound production device 60. The
image acquisition device 60 or the sound production device 60 is
disposed in the hollow region 30 of the organic light-emitting
display panel 100. The image acquisition device 60 can be, for
example, a camera, an image collector, or other devices capable of
photographing, videotaping, image capturing and recognition. The
sound production device 60 can be an earpiece, a sounder or other
devices that can produce sound by vibration.
[0100] The organic light-emitting display device 500 can further
include a sensor 50 located in the half display area 210. The
sensor 50 can be a light-sensing fingerprint unit that detects and
recognizes a fingerprint using a change in light, and performs
unlocking, quick payment, or other operations on the organic
light-emitting display device 500. The sensor 50 may also be a
panel recognition unit configured to collect facial information and
perform unlocking, quick payment or other operations on the organic
light-emitting display device 500. The sensor 50 can also be a
light sensor or a distance sensor configured to detect a distance
of a human body or an object from the organic light-emitting
display device 500, and switch between a display mode and a
non-display mode in the organic light-emitting display panel
100.
[0101] In the organic light-emitting display device 500 provided by
the embodiment of the present disclosure, the hollow area 30, and
the half display area 210 and the full display area 200 surrounding
the hollow area 30 are provided, and the number of the pixel units
P per unit area of the full display area 200 is larger than the
number of the pixel units P per unit area of the half display area
210. In this way, it is possible in the organic light-emitting
display device 500 that not only an independent sensor module or
acquisition module can be provided in the hollow area 30 at the
center of the organic light-emitting display panel 100, but a
sensing unit 50 located in the organic light-emitting display panel
100 can be integrated in the half display area 210 and serve to
display. Therefore, a ratio of a displayable area of the organic
light-emitting display device 500 to a total area of the organic
light-emitting display device 500 can be increased, which can
improve the user experience.
[0102] It should be understood that FIG. 17 is merely one example
of the organic light-emitting display device 500. The organic
light-emitting display device 500 is not limited to the shape or
the state shown in FIG. 17. The organic light-emitting display
device 500 may be rectangular or non-rectangular. The organic
light-emitting display device 500 may have no frame at all, or may
have at least one frame.
