It is a type of paper-like reflective display, also known as an electronic paper display (E-Paper). An electronic paper display mainly consists of an array substrate, a counter substrate, and an electronic ink layer disposed between the array substrate and the counter substrate.
[0003] The array substrate includes signal lines arranged in an array, comprising scan signal lines arranged in the row direction and data signal lines arranged in the column direction. The array substrate also includes pixel driving circuits located at the intersections of the scan signal lines and data signal lines. When a scan signal line signal activates a row of pixel driving circuits, a data signal line signal is written to the pixel driving circuit, driving a sub-pixel for display.
[0004] For large-size electrophoretic display panels, static electricity on the array substrate surface can easily damage the scan signal lines and data signal lines, causing breakages in the scan signal lines and data signal lines, which in turn prevents the pixel driving circuit from driving the sub-pixels to display properly.

[0046] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.
[0047] Example 1
[0048] See Figure 1 and Figure 2 As shown, the display panel includes an array substrate, which includes a substrate and signal lines formed on the substrate. The signal lines include M row scan signal lines 110 and N column data signal lines 120, where M and N are both integers greater than 0.
[0049] Repair methods for display panels include:
[0050] S100: Obtain the signal line of the broken line. The broken signal line includes a connecting section 102 and a separating section 103. The connecting section 102 is connected to the driver chip 200, and the separating section 103 is disconnected from the driver chip 200.
[0051] S200: Connect the separation section 103 to the repair line. The array substrate includes multiple anti-static traces, all of which are connected to the driver chip 200. The multiple anti-static traces include a first anti-static trace 131, a second anti-static trace 132, a third anti-static trace 133, and a fourth anti-static trace 134. The first anti-static trace 131 and the second anti-static trace 132 are respectively located on both sides of the array substrate in the row direction. The two ends of the scan signal line 110 are respectively connected to the first anti-static trace 131 and the second anti-static trace 132 through an anti-static ring 140. The third anti-static trace 133 and the fourth anti-static trace 134 are respectively located on both sides of the array substrate in the column direction. The two ends of the data signal line 120 are respectively connected to the third anti-static trace 133 and the fourth anti-static trace 134 through an anti-static ring 140. The repair line is one of the anti-static traces that intersects with the separation section 103.
[0052] The anti-static ring 140 includes four diodes. The first node of the anti-static ring 140 is connected to the anode of the first diode, the cathode of the first diode is connected to the anode of the second diode, and the cathode of the second diode is connected to the second node. The first connection node of the anti-static ring 140 is connected to the cathode of the third diode, the anode of the third diode is connected to the cathode of the fourth diode, and the anode of the fourth diode is connected to the second node. The first node of the anti-static ring 140 is connected to an anti-static trace, and the second node of the anti-static ring 140 is connected to a signal line.
[0053] The driver chip 200 is disposed on the side of the array substrate near the first row of scan signal lines 110. The driver chip 200 may include a scan driver module and a data driver module integrated together. Assuming the two sides in the row direction of the array substrate are the left and right sides, and the two sides in the column direction of the array substrate are the top and bottom sides, the driver chip 200 may be disposed on the top side of the array substrate.
[0054] The scan signal line 110 is connected to the scan drive module of the driver chip 200 via first connecting lines on the left and right sides, and the data signal line 120 is connected to the data drive module of the driver chip 200. A first anti-static trace 131 is located on the upper side of the array substrate, a second anti-static trace 132 is located on the lower side of the array substrate, and the second anti-static trace 132 is connected to the driver chip 200 via a second connecting line on the right side. A third anti-static trace 133 and a fourth anti-static trace 134 are respectively located on the left and right sides of the array substrate. The array substrate also includes a pixel drive circuit 150, located at the intersection of the scan signal line 110 and the data signal line 120. The array substrate includes a display area 101 and a peripheral area surrounding the display area 101. The pixel drive circuit 150 is located in the display area 101, the anti-static traces and their connecting lines to the driver chip 200 are located in the peripheral area, and the middle portions of the scan signal line 110 and the data signal line 120 are located in the display area 101, with both ends located in the peripheral area.
[0055] In the array substrate of a large-size electrophoretic display panel, in-plane static electricity can easily damage the scan signal line 110 and the data signal line 120, causing breakage in the scan signal line 110 and the data signal line 120, which in turn causes the pixel driving circuit 150 to fail to drive the sub-pixels for display.
[0056] In this embodiment, the array substrate includes anti-static traces connected to the driver chip 200. First anti-static traces 131 and second anti-static traces 132 are respectively disposed on both sides of the array substrate in the row direction, and third anti-static traces 133 and fourth anti-static traces 134 are respectively disposed on both sides of the array substrate in the column direction. When the scan signal line 110 or data signal line 120 is damaged by electrostatic discharge and breaks, the intersecting anti-static traces can be used as repair lines. The separation segment 103 is connected to the repair lines, and the driver chip 200 provides a driving signal to drive it. This embodiment utilizes anti-static traces to repair signal lines damaged by electrostatic discharge, improving the product yield of the display panel. Simultaneously, it eliminates the need for additional repair lines, simplifying the structure of the array substrate and reducing the manufacturing cost of the display panel.
[0057] It should be noted that the driver chip 200 may include an integrated scan driver module and a data driver module, but is not limited to this. The scan driver module and the data driver module may also be set separately. The data driver module may be set on the upper side of the array substrate, and the scan driver module may be set on the left side of the array substrate, depending on the specific situation. The connection lines between the scan signal line 110, the anti-static traces, and the driver chip 200 may be routed from the left side of the array substrate, or from the right side of the array substrate, or partially from the left side and partially from the right side of the array substrate, depending on the specific situation.
[0058] For example, see Figure 1 and Figure 2 As shown, the signal line that is disconnected is the m-th scan signal line 110, where m ≤ M. Figure 2 In the diagram, A represents the electrostatic discharge breakpoint, B represents the connection point, and C represents the laser melting breakpoint. The second anti-static trace 132 intersects with the separation segment 103 of the m-th row scan signal line 110, and the separation segment 103 of the m-th row scan signal line 110 is connected to the second anti-static trace 132. The driver chip 200 outputs a scan signal to the separation segment 103 through the second anti-static trace 132 to drive the sub-pixels for display.
[0059] The second anti-static trace 132 and the scanning signal line 110 can be located on the same or different structural layers, and are insulated at their intersection. For example, the second anti-static trace 132 is located on the upper layer. In specific repairs, a laser can be used to irradiate the intersection of the separation section 103 of the scanning signal line 110 and the second anti-static trace 132, causing the upper layer's second anti-static trace 132 to melt and connect with the lower layer's scanning signal line 110.
[0060] It should be noted that when the broken signal line is the m-th row scanning signal line 110, the second anti-static trace 132 can be used as a repair line for repair, but it is not limited to this. The connecting line of the fourth anti-static trace 134 can also be used as a repair line for repair, depending on the specific situation.
[0061] The second anti-static trace 132 is closer to the scanning signal line 110. Using the second anti-static trace 132 as a repair line makes the connection between the two more convenient, and at the same time does not interfere with the fourth anti-static trace 134 and its connecting line as a repair line for repairing the data signal line 120.
[0062] See Figure 1 and Figure 2 As shown, the repair methods for the display panel include:
[0063] Cut the second anti-static trace 132. The cut position is located between the m-th row scan signal line 110 and the (m+1)-th row scan signal line 110, where m+1≤M. For specific repairs, the second anti-static trace 132 can be irradiated with a laser to melt it.
[0064] Cutting the second anti-static trace 132 can reduce the attenuation of the scanning signal on the second anti-static trace 132 and enhance the driving capability of the scanning signal.
[0065] In some embodiments, see Figure 3 As shown, the repair methods for the display panel also include:
[0066] Connect the scan signal line 110 of the m±1th row to the second anti-static trace 132, where m≥2.
[0067] In other words, when the broken signal line is the m-th row scan signal line 110, the scan signal line 110 adjacent to the broken scan signal line 110 can also be connected to the second anti-static trace 132.
[0068] When the broken signal line is the m-th row scan signal line 110, connecting the adjacent scan signal line 110 to the second anti-static trace 132 allows the scan signal from the adjacent scan signal line 110 to drive the pixel driving circuit 150 controlled by the separation segment 103, thereby reducing the requirements on the driver chip 200. This is especially beneficial for broken scan signal lines 110 located near the top or bottom, or those broken near the left or right. This repair method places low demands on the driver chip 200 and has minimal impact on the display effect. Furthermore, by using adjacent scan signal lines 110 to repair broken scan signal lines 110, multiple broken scan signal lines 110 can be repaired.
[0069] See Figure 3 As shown, the broken signal line is the m-th row scan signal line 110. The separation segment 103 of the m-th row scan signal line 110 is connected to the second anti-static trace 132, and the (m+1)-th row scan signal line 110 is also connected to the second anti-static trace 132. The repair method for the display panel includes:
[0070] Cut the second anti-static trace 132, with the cut position located between the (m-1)th row scan signal line 110 and the mth row scan signal line 110.
[0071] Cutting the second anti-static trace 132 can reduce the attenuation of the scanning signal on the second anti-static trace 132 and enhance the driving capability of the scanning signal.
[0072] It is easy to understand that when the (m-1)th row scan signal line 110 is connected to the second anti-static trace 132, and the second anti-static trace 132 is cut off, the cut-off position is located between the (m-2)th row scan signal line 110 and the (m-1)th row scan signal line 110.
[0073] In some embodiments, see Figure 4 As shown, the disconnected signal line includes the p-th row scan signal line 110, the second anti-static trace 132 intersects with the separation segment 103 of the p-th row scan signal line 110, and the separation segment 103 of the p-th row scan signal line 110 is connected to the second anti-static trace 132, where p < m.
[0074] For the pixel driving circuit 150 controlled by the separation segment 103 of the p-th row scan signal line 110, the scanning signal output by the driver chip 200 can be used for driving. For the pixel driving circuit 150 controlled by the separation segment 103 of the m-th row scan signal line 110, the scanning signal of the (m+1)-th row scan signal line 110 can be used for driving.
[0075] For the scan signal line 110 close to the driver chip 200, the scan signal output by the driver chip 200 is used to repair the upper half of the second anti-static trace 132. For the scan signal line 110 far from the driver chip 200, the scan signal output by the adjacent scan signal line 110 is used to repair the lower half of the second anti-static trace 132. The combination of the two methods can make full use of the second anti-static trace 132 to repair multiple breaks, thereby improving the product yield of the display panel.
[0076] Example 2
[0077] The difference between Example 2 and Example 1 is that the disconnected signal line is data signal line 120.
[0078] See Figure 5 As shown, the disconnected signal lines include the nth column data signal line 120, where n ≤ N. The fourth anti-static trace 134 intersects with the separation segment 103 of the nth column data signal line 120, and the separation segment 103 of the nth row data signal line 120 is connected to the fourth anti-static trace 134.
[0079] The fourth anti-static cable 134 is closer to the separation section 103 of the data signal cable 120, making it easier to connect the two by using the fourth anti-static cable 134 as a repair cable.
[0080] See Figure 5 As shown, the repair methods for the display panel include:
[0081] Cut the fourth anti-static trace 134. The cut position is located between the (n-1)th column data signal line 120 and the nth column data signal line 120, where n≥2.
[0082] Cutting the fourth anti-static trace 134 can reduce the attenuation of the data signal on the fourth anti-static trace 134 and enhance the driving capability of the data signal.
[0083] In some embodiments, see Figure 6 As shown, the repair methods for the display panel also include:
[0084] Connect the data signal line 120 of column n±1 to the fourth anti-static trace 134, where n≥2 and n≤N.
[0085] In other words, when the broken signal line is the nth column data signal line 120, the adjacent data signal line 120 can also be connected to the fourth anti-static trace 134.
[0086] When the broken signal line is the nth column data signal line 120, connecting the adjacent data signal line 120 to the fourth anti-static trace 134 allows the data signal from the adjacent data signal line 120 to drive the pixel driving circuit 150 controlled by the separation section 103, thereby reducing the requirements on the driver chip 200. This is especially beneficial for broken signal lines 120 located on the left or right side, or on the top or bottom side, as this repair method places lower demands on the driver chip 200 and has minimal impact on the display effect. Furthermore, by using adjacent data signal lines 120 to repair broken data signal lines 120, multiple broken data signal lines 120 can be repaired.
[0087] See Figure 6 As shown, the broken signal line is the nth column data signal line 120. The separation segment 103 of the nth row data signal line 120 is connected to the fourth anti-static trace 134, and the (n-1)th column data signal line 120 is connected to the fourth anti-static trace 134. The repair method for the display panel includes:
[0088] Cut the fourth anti-static trace 134. The cut position is located between the nth column data signal line 120 and the (n+1)th column data signal line 120, where n+1≤N.
[0089] In some embodiments, see Figure 7 As shown, when the separation segment 103 of the nth column data signal line 120 is connected to the fourth anti-static trace 134 and the (n-1)th column data signal line 120 is connected to the fourth anti-static trace 134, the disconnected signal line includes the qth column data signal line 120. The fourth anti-static trace 134 intersects with the separation segment 103 of the qth column data signal line 120, and the separation segment 103 of the qth column data signal line 120 is connected to the fourth anti-static trace 134, where q > n.
[0090] For the pixel driving circuit 150 controlled by the separation segment 103 of the q-th column data signal line 120, the data signal output by the driver chip 200 can be used for driving. For the pixel driving circuit 150 controlled by the separation segment 103 of the n-th column data signal line 120, the data signal of the (n-1)-th column data signal line 120 can be used for driving.
[0091] For data signal lines 120 of the connection lines close to the fourth anti-static trace 134, the data signal is output by the driver chip 200 to the right half of the fourth anti-static trace 134 for repair. For data signal lines 120 of the connection lines far from the fourth anti-static trace 134, the data signal is output by the adjacent data signal line 120 to the left half of the fourth anti-static trace 134 for repair. The combination of the two methods can make full use of the fourth anti-static trace 134 to repair multiple breakpoints, thereby improving the product yield of the display panel.
[0092] It should be understood that the method for repairing the data signal line 120 in this embodiment and the method for repairing the scan signal line 110 in an embodiment are implemented using different anti-static traces, and there is no conflict between them; they can be combined arbitrarily.
[0093] Example 3
[0094] See Figure 8 As shown, the display panel includes an array substrate, which includes signal lines. The signal lines include M row scan signal lines 110 and N column data signal lines 120, where M and N are both integers greater than 0. The broken scan signal lines 110 are repaired using the display panel repair method disclosed in Embodiment 1, and the broken data signal lines 120 are repaired using the display panel repair method disclosed in Embodiment 2.
[0095] In this embodiment, the array substrate of the display panel includes anti-static traces connected to the driver chip 200. First anti-static traces 131 and second anti-static traces 132 are respectively disposed on both sides of the array substrate in the row direction, and third anti-static traces 133 and fourth anti-static traces 134 are respectively disposed on both sides of the array substrate in the column direction. When the scan signal line 110 or data signal line 120 is damaged by electrostatic discharge and breaks, the intersecting anti-static traces can be used as repair lines. The separation segment 103 is connected to the repair lines, and the driver chip 200 provides a driving signal to drive it. This embodiment utilizes anti-static traces to repair signal lines damaged by electrostatic discharge, improving the product yield of the array substrate. The array substrate, used in the display panel, reduces the manufacturing cost of the display panel.
