DETAILED DESCRIPTION
[0042] The following description of the various embodiments is
provided with reference to the accompanying drawings. It should be
understood that terms such as "upper", "lower", "front", "rear",
"left", "right", "inside", "outside", "lateral", as well as
derivative thereof should be construed to refer to the orientation
as then described or as shown in the drawings under discussion.
These relative terms are for convenience of description, do not
require that the present disclosure be constructed or operated in a
particular orientation, and shall not be construed as causing
limitations to the present disclosure. In the drawings, the
identical or similar reference numerals constantly denote the
identical or similar elements or elements having the identical or
similar functions.
[0043] Embodiments of the present disclosure can alleviate a
technical problem that conventional display panels cannot meet a
developing trend of full-screen display panels.
[0044] As shown in FIG. 2 and FIG. 3, the present disclosure
provides a display panel, including an array substrate 101 and a
color filter 102 disposed corresponding to the array substrate 101.
A display region 103 is disposed on a surface of the array
substrate 101 and is confined by a frame sealant. A liquid crystal
layer is confined by the frame sealant. The color filter 102 and
the array substrate 101 are combined by the frame sealant.
[0045] Regions between the display region 103 and a periphery of
the array substrate 101 form a non-display region 104. A plurality
of signal wires are distributed in the non-display region 104.
Other electrical components like a driver chip 105 and a flexible
circuit board 106 are bonded to the non-display region 104.
[0046] A length of the color filter 102 is less than that of the
array substrate 101, and a height of the color filter 102 is
greater than that of the array substrate 101. A region between a
projection of a bottom periphery of the color filter 102 on the
surface of the array substrate 101 and a periphery of the array
substrate 101 forms a staircase region. The staircase region is in
the non-display region 104. The driver chip 105, the flexible
circuit board 106, and other electrical components are disposed on
a side of the non-display region 104. In other words, the signal
wires extend from the staircase region to the entire non-display
region 104 and the entire display region 103.
[0047] When a motherboard of the display panel is cut, at least two
protrusions 107 are reserved on a side of the array substrate 101
away from the display region 103. A recess 108 is defined between
adjacent protrusions 107. The driver chip 105 is disposed on a
bottom periphery of the protrusion 107, that is, the driver chip
105 is disposed between a periphery of the non-display region 104
and a periphery of the display region 103. Therefore, a height
difference between a top of the driver chip 105 and a periphery of
the display region 103 is increased, and a height difference
between a bottom of the driver chip 105 and a bottom periphery of
the protrusion 107 is also increased.
[0048] In one embodiment, the protrusion 107 includes at least one
first protrusion 107a and at least one second protrusion 107b. The
first protrusion 107a is disposed on a middle portion of a side of
the array substrate 101. The driver chip 105 is disposed between a
bottom periphery of the first protrusion 107a and a periphery of
the display region 103.
[0049] The flexible circuit board 106 includes a connecting section
connected to the non-display region 104, a main section bent to a
backside of the display panel, and a bending section for connecting
the connecting section with the main section. The bending section
is bent to a backside of the array substrate with respect to a
periphery of the recess 108. That is, the bending section is
disposed in the recess 108. A bending radius of the bending section
is less than or equal to a height of the first protrusion 107a,
that is, the bending section does not overstep the recess 108.
[0050] In one embodiment, the bending section is bent with respect
to a periphery of the recess 108 beside at least one side of the
first protrusion 107a. The bending section may also be bent with
respect to a periphery of the recess 108 beside at least one side
of the second protrusion 107b.
[0051] In an embodiment of the present disclosure, the first
protrusion 107a is disposed according to the amount of the driver
chip 105. A position of the first protrusion 107a and the driver
chip are not limited to a middle portion of the non-display region
104. For example, the first protrusion 107a may also be disposed
near any side of the non-display region 104.
[0052] In an embodiment of the present embodiment, the second
protrusion 107b is disposed according to the amount of the first
protrusion 107a, and is configured to enlarge a contact area
between the protrusion 107 and a cage of a display device. As a
result, forces applied to the display panel can be uniform. The
second protrusion 107b and the first protrusion 107a are not
limited to a manner of staggered arrangement.
[0053] In an embodiment of the present disclosure, the second
protrusion 107b may only have a supporting function, and no
electrical component is disposed on the second protrusion 107b.
However, electrical components required for the display panel, such
as a converting terminal, or electrical components that the display
panel does not require, such as a fingerprint identification device
and a camera, may also be disposed on the second protrusion
107b.
[0054] Consequently, compared to conventional display panels,
spaces near a top side and a bottom side of the driver chip 105 are
broadened in an embodiment of the present disclosure, while an
entire height of the non-display region 104 is not increased. The
present disclosure not only solves the problem that spaces near the
top side and the bottom side of the driver chip 105 are too narrow,
but also retains a narrow non-display region of the conventional
display panels.
[0055] As shown in FIG. 4, reference numeral (1) denotes a display
panel provided by the present disclosure, reference numeral (2)
denotes a conventional display panel, and both of them include an
array substrate 101, a color filter 102, a display region 103, a
driver chip 105, and a flexible circuit board 106. The array
substrate 101 includes a non-display region 104. The non-display
region 104 includes a distance A between a bottom periphery of the
display region 103 and a periphery of the color filter 102, a
height B of the driver chip 105, and a distance C between a top
periphery of the driver chip 105 and a periphery of the color
filter 102. The reference numeral (1) further includes a height D
of the protrusion 107, a distance E between a bottom periphery of
the driver chip 105 and a periphery of protrusion 107, and a height
F between a bottom periphery of the color filter 102 and a
periphery of a recess of the non-display region 104. The reference
numeral (2) further includes a distance F between a bottom
periphery of the color filter 102 and a periphery of the flexible
circuit board 106.
[0056] In an embodiment of the present disclosure, a total height
of the non-display region is the distance A+the distance F+the
height D. The distance A is equal to the distance F, a difference
between the distance A and the distance F is less than 50 um, and
the height D is greater than a difference between the distance B
and the distance F. For example, the height D is five to six times
the difference between the height B and the distance F, thereby
ensuring that the distance C and the distance E are not less than
100 um. Specific setting way is shown in the following table 1:
TABLE-US-00001 TABLE 1 A B C D E F (1) of FIG. 4 700 780 200 400
120 700 (2) of FIG. 4 540 780 80 0 0 860
[0057] In table 1, unit of height is micrometers.
[0058] Referring to table 1, in the display panel provided by an
embodiment of the present disclosure, a height of the protrusion
107 is increased and a driver chip 105 is moved downward. As a
result, a height difference A between a bottom periphery of the
display region 103 and a periphery of a color filter 102 and a
height difference C between a top periphery of the driver chip 105
and a periphery of the color filter 102 are both increased. The
distance F between a bottom periphery of the color filter 102 and a
periphery of the non-display region 104 is reduced with respect to
the conventional display panels. In an embodiment of the present
disclosure, a total height of the non-display region 104 and a
bending section (in a bending state) of the flexible circuit board
106 is less than that of the conventional display panels, and a
height of the non-display region 104 is further reduced.
[0059] In one embodiment, to reserve sufficient space to dispose
GOA wires, fan-out wires, and terminals, a distance between a side
of the driver chip near the display region and a periphery of the
display region is designed to be greater than a distance between a
side of the first protrusion near the driver chip and a periphery
of the first protrusion.
[0060] A position of the driver chip can be varied and can be
designed as needed.
[0061] In one embodiment, the driver chip is disposed in the
non-display region and disposed outside the first protrusion.
[0062] In one embodiment, the driver chip is completely or
partially disposed in the first protrusion.
[0063] In one embodiment, shapes of the protrusions 107 may be
various. For example. shapes of the protrusions 107 can be one or
more of a rectangle, a trapezoid, an arc, and a triangle. All
shapes of the protrusions 107 may be the same, may be different, or
may be partially the same, which depends on a practical circuit
arrangement.
[0064] In one embodiment, a shape of the second protrusion, which
is defined on a first lateral side, is a rectangle; a shape of the
first protrusion, which is defined on a middle portion, is a
trapezoid or an arc; and a shape of the second protrusion, which is
defined on a second lateral side, is a triangle.
[0065] In one embodiment, as shown in FIG. 5, a display panel
provided by the present disclosure includes an array substrate 101,
a color filter 102, a display region 103, and a protrusion 107
defined on a side of the array substrate 101. A driver chip 105 is
disposed in a non-display region 104 of the array substrate
101.
[0066] The protrusion 107 includes two short sides symmetrical to
each other and connecting a periphery of the non-display region
104. The protrusion 107 further includes a long side connecting two
short sides. For example, as shown in FIG. 5, the short sides are
straight sides and are perpendicular to the periphery of the
non-display region 104, and a surface shape of the protrusion 107
is a rectangle.
[0067] In one embodiment, the protrusion 107 includes two short
sides symmetrical to each other and connecting a periphery of the
non-display region 104, and the protrusion 107 further includes a
long side connecting two short sides. As shown in FIG. 6,
differences between the display panel of FIG. 6 and the display
panel of FIG. 5 are: the short sides are straight sides, while
angles between the short sides and the periphery of the non-display
region 104 are not right angles, which means the angles are greater
than or less than 90 degrees, and a surface shape of the protrusion
107 is a trapezoid.
[0068] In one embodiment, as shown in FIG. 7, differences between
the display panel of FIG. 7, the display panel of FIG. 5, and the
display panel of FIG. 6 are: the protrusion 107 includes an outer
arc, two ends of the outer arc connect with the periphery of the
non-display region 104, and two ends of the outer arc are curved
toward an inside of the outer arc.
[0069] A setting way of a flexible circuit board is described as
follows:
[0070] As shown in FIG. 8, a display panel provided by the present
disclosure includes an array substrate 101, a color filter 102, a
non-display region 104, a driver chip 105 disposed in the
non-display region 104, and a plurality of fan-out wires 801
connecting with the driver chip 105. For example, the fan-out wires
801 are configured to transmit data signals for displaying to the
display region 103. At least one GOA wire 802 is disposed in the
non-display region 104. Two GOA wires 802, which are symmetrical to
each other, are taken as an example. Both of the two GOA wires 802
include a straight section disposed outside the display region 103
and parallel to a periphery of the display region 103, and a tilt
section disposed in the non-display region 104 and disposed toward
the driver chip 105. The tilt sections of the two GOA wires 802 are
connected to the driver chip 105 to input gate signals. The
straight sections of the two GOA wires 802 are connected to scan
lines of each pixel row to output gate signals.
[0071] A plurality of signal terminal groups for connecting the
flexible circuit board are disposed in the non-display region 104.
Each of the terminal groups at least includes a main signal
terminal group 803 and a secondary signal terminal group 804. For
example, the main signal group 803 includes pixel data signals and
gate signals. The secondary signal terminal group 804 includes
power signals. The main signal terminal group 803 is disposed
between the secondary terminal group 804 and the driver chip 105 to
reduce delay in transmitting signals.
[0072] In one embodiment, as shown in FIG. 8, the main signal
terminal group 803 is disposed near the driver chip 105. The
secondary terminal group 804 is disposed away from the driver chip
105 and the tilt section of the two GOA wires 802. Because the
driver chip 105 is moved downward, the tilt sections of the two GOA
wires 802, which are connected to the driver chip 105, are moved
downward as well, which compresses space where terminals are
disposed. If the terminals are too close to the two GOA wires 802,
impedance increases, causing signal distortion. As a result, in the
present embodiment, at least some of the terminals are disposed
away from the two GOA wires 802.
[0073] In one embodiment, the secondary signal terminal group 804
is spaced from the main signal terminal group 803. The main signal
terminal group 803 is completely or partially disposed in the first
protrusion 107a, and the secondary signal terminal group 804 is
disposed outside the protrusion 107a, thereby effectively
controlling a distance between the terminals and the two GOA wires
802 to reduce impedance.
[0074] As shown in FIG. 9, the flexible circuit board includes a
main section 1061 and a connecting section configured to connect
with the signal terminal groups. The connecting section includes a
first block 1062 correspondingly connected to the main signal
terminal group 803 and a second block 1063 correspondingly
connected to the secondary signal terminal group 804. The first
block 1062 and the second block 1063 are disposed
alternatively.
[0075] As shown in FIG. 10, compared to the setting way of signal
terminals in FIG. 8, the terminals are arranged tightly. The main
signal terminal group 803 and the secondary signal terminal group
804 are disposed outside the first protrusion 107a, thereby
preventing space of the first protrusion 107a from being
compressed. Area of each of the terminals of the main signal
terminal group 803 and area of each of the terminals of the
secondary signal terminal group 804 are the same, thereby ensuring
that signal contact points can be connected stably.
[0076] In one embodiment, a height of each of the terminals of the
main signal terminal group 4071 is less than a height of each of
the terminals of the secondary terminal group 4072. Furthermore, a
width of each of the terminals of the main signal terminal group
4071 is greater than a width of each of the terminals of the
secondary signal terminal group 4072. By reducing the height of the
terminals near the two GOA wires 802 to maintain a distance between
the terminals and the two GOA wires 802, impedance between the
terminals and the two GOA wires 802 can be reduced.
[0077] In one embodiment, a height of each of the terminals of the
main signal terminal group 803 progressively decreases from the
terminals away from the driver chip 105 and the tilt sections of
the two GOA wires 802 to the terminals near the driver chip 105 and
the tilt sections of the two GOA wires 802. Furthermore, a width of
each of the terminals of the main signal terminal group 803
progressively increases from the terminals away from the driver
chip 105 and the tilt sections of the two GOA wires 802 to the
terminals near the driver chip 105 and the tilt sections of the two
GOA wires 802, thereby ensuring that distances between each of the
terminals and the two GOA wires 802 are the same.
[0078] As shown in FIG. 11, the flexible circuit board includes a
main section 1061 and a connecting section 1064 configured to
connect with the signal terminal groups. Ends of the connecting
section 1064 are a regular geometric shape. The ends of the
connecting section 1064 include a first connecting area and a
second connecting area. The first connecting area covers and
connects with the main signal terminal group. The second connecting
area covers and connects with the secondary signal terminal
group.
[0079] In one embodiment, each of the signal terminal groups
further includes a virtual terminal group. The virtual terminal
group is disposed on a side of the secondary signal terminal group
4072 away from the driver chip 105 and the tilt section of the GOA
wire 802 Terminals of the virtual terminal group do not transmit
signal, but are configured to enlarge binding area between a panel
and the flexible circuit board to enhance connection effect,
thereby supporting the flexible circuit board and ensuring flatness
of the panel.
[0080] A setting way of circuit on a second protrusion is described
as follows:
[0081] In one embodiment, as shown in FIG. 12, a display panel
provided by the present disclosure includes an array substrate 101,
a color filter 102, a non-display region 104 disposed on the array
substrate 101, a testing terminal group 805 disposed in the
non-display region 104, a converting terminal group 806, and an
identification terminal group 807. At least one of the testing
terminal group 805, the converting terminal group 806, or the
identification terminal group 807 is disposed between a periphery
of a second protrusion 107b and a periphery of the display region
103.
[0082] The testing terminal group 805, the converting terminal
group 806, and the identification terminal group 807 may be
disposed between the periphery of the second protrusion 107b and
the periphery of the display region 103 in a same row, or can be
disposed between the periphery of the second protrusion 107b and
the periphery of the display region 103 in different rows.
[0083] In one embodiment, to enlarge gaps between the testing
terminal group 805, the converting terminal group 806, and the
identification terminal group 807, as shown in FIG. 13, in a
display provided by the present embodiment, the testing terminal
group 805, the converting terminal group 806, and the
identification terminal group 807 are disposed in at least two
rows.
[0084] The testing terminal group 805 is configured to test
performance of the display panel by inputting testing signals into
terminals of the testing terminal group 805 after the display panel
is formed from the array substrate. A silver conductive adhesive is
coated on the converting terminal group 806. The silver conductive
adhesive is configured to connect a ground wire (not shown) in the
non-display region 101 of the array substrate with a conductive
layer of a color filter corresponding to the array substrate of the
display panel, thereby preventing static electricity. Terminals of
the identification terminal group 807 are configured to record
information about the array substrate and are configured to align
the array substrate.
[0085] In one embodiment, the present disclosure further provides a
display device. The display device includes a display panel. The
display panel includes an array substrate, a display region
disposed on a surface of the array substrate, and a non-display
region formed on a region where the array substrate does not cover.
A driver chip and a flexible circuit board are bonded to the
non-display region. A plurality of protrusions are defined on a
side of the non-display region away from the display region. A
recess is defined in adjacent protrusions. Each of the protrusions
includes at least one first protrusion and at least one second
protrusion. The driver chip is disposed between a periphery of the
first protrusion and a periphery of the display region.
[0086] Partial section of the flexible circuit board is bent to a
backside of the array substrate with respect to a periphery of the
recess beside at least one side of the first protrusion.
[0087] In one embodiment, in the display device, a distance between
a side of the driver chip near the display region and a periphery
of the display region is greater than a distance between a side of
the first protrusion near the driver chip and a periphery of the
first protrusion.
[0088] In one embodiment, in the display device, the driver chip is
disposed outside the first protrusion, or the driver chip is
completely or partially disposed in the first protrusion.
[0089] In one embodiment, in the display device, the protrusion
includes two short sides symmetrical to each other and connecting a
periphery of the non-display region. The protrusion further
includes a long side connecting two short sides. The short sides
are perpendicular to the periphery of the non-display region, or
angles between the short sides and the periphery of the non-display
region are not right angles.
[0090] In one embodiment, in the display device, the protrusion
includes an outer arc. Two ends of the outer arc connect with the
periphery of the non-display region. Two ends of the outer arc are
curved toward an inside of the outer arc.
[0091] In one embodiment, in the display device, a GOA wire is
disposed in the array substrate. The GOA wire includes a tilt
section located in the non-display region and toward the driver
chip. The tilt section of the GOA wire is connected to the driver
chip. A plurality of signal terminal groups are disposed in the
non-display region and are configured to connect with the flexible
circuit board. The signal terminal groups include a main signal
terminal group and a secondary terminal group. The main signal
terminal group is disposed between the secondary terminal group and
the driver chip.
[0092] In one embodiment, in the display device, the secondary
signal terminal group and the main signal terminal group are spaced
from each other. The main signal terminal group is completely or
partially disposed in the first protrusion. The secondary signal
terminal group is disposed outside the first protrusion.
[0093] In one embodiment, in the display device, the flexible
circuit board includes a main section and a connecting section. The
connecting section includes a first block correspondingly connected
to the main signal terminal group and a second block
correspondingly connected to the secondary signal terminal group.
The first block and the second block are disposed
alternatively.
[0094] In one embodiment, in the display device, a virtual terminal
group is disposed in the non-display region. The virtual terminal
group is disposed on a side of the secondary signal terminal group
away from the driver chip and the tilt section of the GOA wire.
[0095] In one embodiment, in the display device, the non-display
region further includes a testing terminal group, a converting
terminal group, and an identification terminal group. At least one
of the testing terminal group, the converting terminal group, or
the identification terminal group is disposed between an edge of
the second protrusion and an edge of the display region.
[0096] In the display panel provided by an embodiment of the
present disclosure, the testing terminal group, the converting
terminal group, and the identification terminal group are disposed
in at least two rows.
[0097] According to the above embodiments,
[0098] The present disclosure provides a display panel and a
display device; in an array substrate of the display panel, at
least two protrusions are defined on a side of a non-display region
away from a display region to form an extending portion. A recess
is defined between adjacent protrusions. Compared to conventional
display panels, in the display panel provided by the present
disclosure, a driver chip is disposed in a space between a
periphery of a display region and a periphery of a non-display
region. Distances between the driver chip, the periphery of the
display region, and the periphery of the non-display region are
increased, which prevent technical defects following a pressing
process of the driver chip, such as poor electrical property of the
driver chip and improperly sealed liquid crystal cell, which are
caused by the driver chip being excessively close to the periphery
of the display region and a periphery of a substrate due to a
compression of the non-display region in a high screen-to-body
ratio display panel. Furthermore, a bending section of a flexible
circuit board is disposed in the recess between two adjacent
protrusions. A bending radius of the bending section does not
overstep peripheries of the protrusions. As a result, width of the
non-display region will not be increased, body-to-screen ratio of a
display device can be kept, and a technical problem that
conventional display panels cannot meet a developing trend of
full-screen display technology can be alleviated.
[0099] To sum up, the present disclosure has been described with a
preferred embodiment thereof. The preferred embodiment is not
intended to limit the present disclosure, and it is understood that
many changes and modifications to the described embodiment can be
carried out without departing from the scope and the spirit of the
disclosure that is intended to be limited only by the appended
claims.
