Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a display substrate having an
arched signal transmission line and a manufacture method thereof;
and more specifically to a liquid crystal display substrate having
an arched signal transmission line and a manufacture method
thereof.
[0003] 2. Description of the Prior Art
[0004] Flat display panels and the flat display devices using the
flat display panels are now the mainstream display devices on the
market; especially the liquid crystal display panels are
extensively used in display devices for electronic products such as
home flat television, flat monitors of personal computers and
laptop computers, display screens of mobile phones and digital
cameras.
[0005] In order to transmit image data, a plurality of signal
transmission lines are disposed on the surface of a flat display
substrate. FIG. 1 is a top view of a conventional flat display
substrate. As FIG. 1 shows, the conventional display substrate
includes a first panel substrate 10 and a second panel substrate
20, wherein the panel substrates 10, 20 will be separated at the
separation line 40 after a panel performance test is completed. A
test line 50 and an active area (or namely pixel area, or namely
display area) 12 are disposed on the surface of the first panel
substrate 10. During the performance test, the test line 50 accepts
test signals from probes (not illustrated) and then transmits the
test signals to the active area 12. The test signals simulate the
signals during normal operation and drive the active area 12 to
inspect whether the display panel can function normally.
[0006] As FIG. 1 shows, due to the layout requirement of the
display panel, part of the test line 50 overlaps the signal line
60, wherein the signal line 60 is used to transmit electrical
signals during normal operation. As FIG. 1 shows, the test line 50
and the signal line 60 overlap and thus parasitic capacitance
exists between the test line 50 and the signal line 60. Thus, in
the performance test, part of the test signal will be transformed
into static charges and stored in the parasitic capacitance between
the test line 50 and the signal line 60. After the display panel
passes the performance test and starts normal operations, the
stored static charges which are accumulated to a certain level may
be discharged and damage the protection layer and the insulation
layer between the test line 50 and the signal line 60. In this way,
electrical signals cannot be correctly transmitted due to
short-circuit and thus the display panel cannot correctly display
desired images.
SUMMARY OF THE INVENTION
[0007] It is an object of the present invention to provide a
display substrate having an arched signal transmission line to
avoid the accumulation of static charges between a signal test line
and a signal transmission line.
[0008] It is another object of the present invention to provide a
display substrate having an arched signal transmission line to
prevent the short-circuit between the signal test line and the
transmission line from interfering the accuracy of the images
displayed by the display panel.
[0009] It is yet another object of the present invention to provide
a display substrate having an arched signal transmission line avoid
short-circuit between signal test line and a signal transmission
line to improve the reliability of the display panel.
[0010] The display substrate of the present invention includes a
first substrate, a second substrate, a first transmission line, a
second transmission line, and a signal test pad. A first cutting
line is defined between the first substrate and the second
substrate and the two substrates are disposed with a first active
area circuit and a second active area circuit, respectively. Two
ends of the first transmission line are electrically connected to
the signal test pad and the first active area, respectively. The
signal test pad accepts test signals from a probe and transmits the
test signals to the first active area circuit via the first
transmission line for the first active area circuit to display
images accordingly. The first transmission line includes at least
three line portions. Two ends of the middle line portion are
electrically connected to the display line portion and the end line
portion, respectively. One end of the end line portion is connected
to the signal test pad and the one end of the display line portion
is connected to the first active area circuit. The middle line
portion is disposed on the second substrate, wherein two ends of
the middle line portion are respectively connected to the display
line portion and the end line portion at the first cutting line.
Furthermore, after the panel performance test is performed, the
first substrate and the second substrate will be separated by
cutting along the first cutting line. In other words, the display
substrate is separated into at least the first substrate and the
second substrate, and simultaneously the middle line portion is
separated from the end line portion and the display line
portion.
[0011] The second transmission line is disposed on the display
substrate, wherein the second transmission line crosses over the
first cutting line and is disposed on both the first substrate and
the second substrate. In one embodiment, part of the end line
portion and the second transmission line overlap the therefor
parasitic capacitance is created between the end line portion and
the second transmission line. In this way, there may be static
charges accumulated in the parasitic capacitance due to test
signals even after the panel performance test is completed. The
static charges can be accumulated and discharged when reaching a
certain level to destroy the protective layer and the insulation
layer between the end line portion and the second transmission
line. In this way, the exposed signal line may short-circuit the
test line. However, after the first substrate and the second
substrate are separated, the middle line portion is also separated
from the end line portion and the display line portion and thus the
end line portion is also separated and electrically disconnected
from the display line portion. Thus even if the end line portion
short-circuit the second transmission line due to electrostatic
discharge, the first active area circuit will not receive
electrical signals from the second transmission line and
inaccurately display of images can be prevented.
[0012] Furthermore, the middle line portion is disposed on the
second substrate and forms an arch, wherein a rectangular space is
enclosed on the second substrate by the middle line portion and the
first cutting line, but is not limited thereto. In different
embodiments, the above-mentioned space can be circular, triangular,
angle, taper, or other suitable shapes by adjusting the layout of
the middle line portion.

[0022] FIG. 2A is a top view of the display substrate of the
present invention. In the present embodiment, the display substrate
is a display device mother substrate 100 including a first
substrate 110, a second substrate 210, a first transmission line
500, a second transmission line 600 and signal test pad 800,
wherein the signal test pad 800 is used to accept test signals from
probes (not illustrated) during a panel performance test. The
display device mother substrate 100 of the present embodiment is a
glass substrate and a first cutting line 400 is disposed between
the first substrate 110 and the second substrate 210. Two
substrates 110, 210 are disposed with a first active area 120 and a
second active area 220, respectively. Wherein, the active area is
also namely the pixel area or the display area. The first active
area 120 and the second active area 220 have a first active area
circuit (not illustrated) and a second active area circuit (not
illustrated), respectively. In the present embodiment, the display
device mother substrate 100 includes only the first substrate 110
and the second substrate 210, but is not limited thereto; in other
embodiments, the display device mother substrate 100 can also
include other number of substrates. Furthermore, after the
performance test is completed, the first substrate 110 and the
second substrate 210 are separated by cutting the display device
mother substrate 100 along the first cutting line 400. In other
words, the first cutting line 400 is a reference line for cutting
the display device mother substrate 100 into separate substrates.
The display device mother substrate 100 will be separated into the
first substrate 110 and the second substrate 210.
[0023] As shown in FIG. 2A, the first transmission line 500
includes at least three segments, i.e. a display line portion 510,
an end line portion 520, and a middle line portion 530, wherein the
display line portion 510 and the end line portion 520 are located
on the first substrate 110 while the middle line portion 530 is
disposed on the second substrate 210. Two ends of the middle line
portion 530 are electrically connected to the display line portion
510 and the end line portion 520, respectively. Two ends of the end
line portion 520 are electrically connected to the signal test pad
800 and the middle line portion 530, respectively. Test signal from
the signal test pad 800 is transmitted to the first active area 120
via the first transmission line 500 for the first active area 120
to display images according to the test signal. In other words, the
test signal is used to simulate the normal operation of the first
substrate 110 and to inspect whether the first substrate 110 can
display images properly.
[0024] As FIG. 2A shows, the second transmission line 600 is
disposed on the display device mother substrate 100, wherein the
second transmission line 600 crosses over the first cutting line
400 to be located on both the first substrate 110 and the second
substrate 210. As FIG. 2A shows, part of the end line portion 520
overlaps the second transmission line 600, wherein the end line
portion 520 is perpendicular to the second transmission line 600
and partially overlaps the second transmission line 600, but is not
limited thereto. In different embodiments, the end line portion 520
can overlap the second transmission line 600 in different
orientation, or the second transmission line 600 can be disposed
over the end line portion 520 or the middle line portion 530.
Furthermore, in the present embodiment, the second transmission
line 600 is used to transmit the test signal, but is not limited
thereto. In other embodiments, the second transmission line 600 can
transmit other electrical signals during panel performance test or
normal operation. Furthermore, the middle line portion 530 and the
first cutting line 400 encloses a rectangular space 820 having a
space width 810, wherein the space width 810, the width of the
middle line portion 530, and the dimension of the space 820 can be
adjusted according to the layout requirement.
[0025] As FIG. 2A shows, two ends of the middle line portion 530
are adjacent to the first cutting line 400 and electrically
connected to the display line portion 510 and the end line portion
520. Due to the fact that the end line portion 520 is disposed over
the second transmission line 600, a parasitic capacitance exists
between the end line portion 520 and the second transmission line
600. During the performance test, static charges may be accumulated
between the end line portion 520 and the second transmission line
600. The static charges may be discharged when reaching a certain
level and may damage the protective layer and the insulation layer
between of the end line portion 520 and the second transmission
line 600 to short-circuit the end line portion 520 and the second
transmission line 600. In this way, the electrostatic discharge may
cause the first transmission line 500 and the second transmission
line 600 to short-circuit and disrupt the signals transmitted.
According to the embodiments of the present invention, when the
first substrate 110 and the second substrate 210 are separated by
cutting along the first cutting line 400, the middle line portion
530 will also be separated from the display line portion 510 and
the end line portion 520. Thus, even if the second transmission
line 600 short-circuits the end line portion 520, the second
transmission line 600 will not short-circuit the first active area
120 after the first substrate 110 is separated from the second
substrate 210. In this way, signal distortion due to short-circuit
between signal lines can be avoided. In the embodiment illustrated
in FIG. 2A, the end line portion 520 crosses over the second
transmission line 600 to electrically couple with the signal test
pad 800. Furthermore, the first transmission line 500 is disposed
on both the first substrate 110 and the second substrate 210 in an
arched shape. In the present embodiment, the middle line portion
530 forms a rectangular arch on the second substrate 210; in other
words, the middle line portion 530 and the first cutting line 400
enclose a rectangular space on the second substrate 210, but is not
limited thereto; in different embodiments, the middle line portion
530 and the first cutting line 400 can enclose a space in of other
suitable shapes according to the layout requirements.
[0026] FIG. 2B illustrates the first substrate 110 and the second
substrate 210 separated from each other, wherein the two substrates
110, 210 are obtained by cutting the display device mother
substrate 100 along the first cutting line 400. As FIG. 2B shows,
the display line portion has a first end 511 and a second end 512,
wherein the first end 511 is electrically connected to the active
area circuit 120. The second end 512 extends to be exposed outside
a first edge 111 of the first substrate 110. The middle line
portion 530 is separated from the end line portion 520 and the
display line portion 510 when the first substrate 110 is separated
from the second substrate 210. In other words, the end line portion
520 is electrically disconnected from the display line portion 510
when the two substrates 110, 210 are separated. Thus a third end
521 of the end line portion 520 extends to be exposed outside the
first edge 111 of the first substrate 110 and a gap 540 exists
between the second end 512 of the display line portion 510 and the
third end 521 of the end line portion 520. Furthermore, as FIG. 2B
shows, the middle line portion 530 is disposed circuitously on the
second substrate 210, wherein the middle line portion 520 includes
a fourth end 531 and a fifth end 532 extending to be exposed
outside a second edge 211 of the second substrate 210,
respectively. Thus, when the two substrates 110, 210 are separated,
the fourth end 531 and the fifth end 532 are also separated from
the display line portion 510 and the end line portion 520 of the
first substrate 110, respectively.
[0027] For this reason, even if the end line portion 520
short-circuits the second transmission line 600 due to
electrostatic discharge, signals to the circuit of the first active
area 120 will not be distorted because the display line portion 510
is electrically disconnected from the middle line portion 530 and
the end line portion 520. In other words, the second transmission
line 600 can cross over the entire first transmission line 500
except the display line portion 510.
[0028] FIG. 3 illustrates a modification of the display substrate
illustrated in FIG. 2A. In the embodiment illustrated in FIG. 3,
part of the first transmission line 500 is disposed along the first
cutting line 400, wherein the middle line portion 530 and the first
cutting line 400 forms a triangular space 820 on the second
substrate 210. In other words, the triangular space 820 is enclosed
on the second substrate 210, but is not limited thereto. In
different embodiments, the shape of the space 820 can be changed by
adjusting the layout of the display device mother substrate
100.
[0029] FIG. 4A illustrates yet another modification of the display
device mother substrate 100 illustrated in FIG. 2A. In the present
embodiment, the display device mother substrate 100 further
includes a third substrate 300 adjacent to the first substrate 110
and the second substrate 210, wherein a second cutting line 410 is
located between the third substrate 300 and the substrates 110,
210. A third transmission line 700 is disposed on the third
substrate 300 which is substantially parallel to the second
transmission line 600. The third transmission line 700 is
electrically connected to the end line portion 520 of the first
transmission line 500. In the present embodiment, the third
transmission line 700 is electrically connected to a signal test
pad (not illustrated) for accepting test signals and transmits the
test signals from the first transmission line 700 to the first
active area 120 of the first substrate 110 for the first active
area 120 to display images accordingly.
[0030] In the present embodiment, the first substrate 110 and the
second substrate 210 are separated from the third substrate 300 by
cutting along the second cutting line 410. Furthermore, the first
substrate 110 and the second substrate 210 are separated by cutting
along the first cutting line 400. Thus, the end line portion 520
will be separated from the third transmission line 700 and the
middle line portion 530. Even if the end line portion 520
short-circuits the second transmission line 600 due to
electrostatic discharge, the first active area 120 will not display
inaccurate images caused by the electrical signals from the second
transmission line 600. FIG. 4B illustrates another embodiment of
the display device mother substrate 100. In the present embodiment,
the middle line portion 530 of the first transmission line 500 is
repeatedly bent and disposed on the first substrate 110 and the
second substrate 210 with the end line portion 520 partially
overlapping the second transmission line 600. In the present
embodiment, the second transmission line 600 and the third
transmission line 700 are respectively electrically connected to
signal test pads (not illustrated) to receive test signals, wherein
the second transmission line 600 transmit the test signals
elsewhere while the transmission line 700 transmits the test
signals to the first active area 120 via the first transmission
line 500, but are not limited thereto; in different embodiments,
the second transmission line 600 and third transmission line 700
can be used to transmit other electrical signals.
[0031] FIG. 5 is a flow chart illustrating a manufacture method of
the display device mother substrate 100 illustrated in FIG. 2A. As
FIG. 5 shows, step S700 includes providing a display device mother
substrate, such as a glass substrate, including a first substrate
and a second substrate, wherein the first substrate is disposed
with an active area for displaying images. The first substrate and
the second substrate are adjacent to each other, but are not
limited thereto. The above-mentioned first substrate and second
substrate are substantially part of the display device mother
substrate and a first cutting line is defined between the two
substrates. In the present embodiment, the display device mother
substrate includes two sub-substrates such as the first and second
substrates, but is not limited thereto; in different embodiments,
the display device mother substrate can include other number of
sub-substrates as appropriate. In the present embodiment, the first
substrate is a glass substrate used in liquid crystal display,
wherein the active area disposed on the first substrate includes
thin-film transistors, color filters, image driver, signal test
pads and an active area circuit, but is not limited thereto; in
different embodiments, the active area can include organic light
emitting diode or other elements and the second substrate may also
include an active area.
[0032] As FIG. 5 shows, step S710 of the manufacture method
includes disposing a second transmission line on the display device
mother substrate. In the present embodiment, the second
transmission line crosses over the first cutting line between the
first substrate and the second substrate and is disposed on both
the first substrate and the second substrate.
[0033] Step S720 illustrated in FIG. 5 includes disposing an arched
first transmission line on the display device mother substrate,
wherein the first transmission line crosses over the first cutting
line and is disposed on both the first substrate and the second
substrate. The first transmission line includes a display line
portion, an end line portion, and a middle line portion, wherein
two ends of the middle line portion are connected to the display
line portion and the end line portion, respectively. In the present
embodiment, the display line portion is electrically connected to
the active area circuit while the end line portion is electrically
connected to a signal test pad which accepts test signals from a
probe. In other words, during a performance test, the first
transmission line can accept test signals from the probe and then
transmit the test signals to the active area circuit, but is not
limited thereto. In different embodiments, the end line portion is
electrically connected to an image driving element or other
electrical elements. The display line portion and the end line
portion are disposed substantially on the first substrate and the
middle line portion is disposed substantially on the second
substrate. In addition, the middle line portion is connected to
both the display line portion and the end line portion at the first
cutting line between the first substrate and the second
substrate.
[0034] In the embodiment illustrated in FIG. 5, step 720 includes
disposing the first transmission line on top of the second
transmission line. In other words, the first transmission line and
the second transmission line overlaps each other in a cross manner
on the display device mother substrate. In the present embodiment,
the second transmission line perpendicular to the end line portion
of the first transmission line and partially overlaps the end line
portion, but is not limited thereto. In different embodiments, the
second transmission line can cross over other portions of the first
transmission line such as the middle line portion, or the two
transmission lines can overlap each other in a slanted manner at
any angle as appropriate.
[0035] Furthermore, in step S720 illustrated in FIG. 5, the middle
line portion of the first transmission line is disposed
circuitously on the second substrate. In the present embodiment,
the middle line portion on the second substrate is arched, wherein
a space exists between the middle line portion and the first
cutting line. In one modification of the present invention, the
middle line portion is adjusted to have a triangular shape on the
second substrate, wherein a triangular space is enclosed between
the middle line portion and the first cutting line, but is not
limited thereto; in different embodiments, the middle line portion
can be adjusted according to layout requirement to have other
shapes.
[0036] Step S730 in FIG. 5 includes cutting the display device
mother substrate into the first substrate and the second substrate,
wherein the display device mother substrate is cut along the first
cutting line. In other words, the first cutting line is used as a
reference line for cutting the display device mother substrate. The
middle line portion is electrically connected to the display line
portion and the end line portion at the first cutting line, thus
step S730 also separates the middle line portion from the display
line portion and the end line portion when cutting the display
device mother substrate.
[0037] Furthermore, FIG. 6 is a flow chart of a manufacture method
of the display device mother substrate 100 illustrated in FIG. 4A.
As FIG. 6 shows, step S900 includes providing a display device
mother substrate which at least includes one first substrate, one
second substrate, one third substrate, wherein the first substrate
is disposed with an active area, but is not limited thereto. The
first substrate, the second substrate, and the third substrate are
adjacent, but are not limited thereto. For instance, the third
substrate is adjacent to both the first substrate and the second
substrate, wherein a second cutting line exists between the
substrates. Furthermore, the display device mother substrate is a
glass substrate, but is not limited thereto; in different
embodiments, the display device mother substrate can be a plastic
substrate or substrates made of other materials.
[0038] As FIG. 6 shows, the manufacture method includes step S910
of disposing a second transmission line on the display device
mother substrate. In the present embodiment, the second
transmission line crosses over the first cutting line between the
first substrate and the second substrate and is disposed on both
the first substrate and the second substrate. Step S910 can also
include disposing a third transmission line on the third substrate
of the display device mother substrate, wherein the third
transmission line is parallel to the second transmission line.
[0039] Step S920 includes disposing a first transmission line
circuitously on the display device mother substrate, wherein the
first transmission line crosses over the first cutting line and is
disposed on both the first substrate and the second substrate. The
first transmission line includes a display line portion, an end
line portion, and a middle line portion, wherein two ends of the
middle line portion are connected to the display line portion and
the end line portion, respectively. Furthermore, step S920
illustrated in FIG. 6 includes disposing part of the end line
portion on the third substrate, wherein the end line portion
crosses over the second cutting line and electrically connects with
the third transmission line.
[0040] Step S930 illustrated in FIG. 6 includes cutting the display
device mother substrate along the first cutting line and the second
cutting line to separate the first substrate, the second substrate
and the third substrate. The middle line portion is connected to
the display line portion and the end line portion at the first
cutting line and thus step S930 also separates the middle line
portion from the display line portion and the end line portion.
Furthermore, step S930 also includes cutting off the end line
portion when separating the first substrate from the third
substrate along the second cutting line.
