Description

A display panel, its repair method and display device

technical field

The invention relates to the field of display technology, in particular to a display panel, its repair method and a display device.

Background technique

During the production process of LCD panels, due to process defects or environmental problems, signal lines such as disconnected data lines or short circuits between data lines and scanning lines will be caused. These two defects seriously affect the display quality of LCD panels and lower the quality of products. Rate. With the improvement of the resolution of the liquid crystal panel and the reduction of the line width, the ratio of these two types of defects also increases.

In view of the above disadvantages, the traditional repair design is shown in Figure 1, which mainly includes repair line 1 L1 and repair line 2 L2; when a certain data line is disconnected, the signal output by the source driver chip is divided into two channels, One of them is directly output to the lower half of the data line, the other is transmitted to the flexible circuit board PCB through the repair line 2 L2, and then transmitted to the upper half of the data line through the repair line 1 L1 (as shown by the arrow in Figure 1). Finally, the repair of the disconnection signal is realized. In actual maintenance, since the repair line-L1 crosses the signal lines one by one at the bottom of the LCD panel (the opposite side of the PCB), there are problems of large delay and voltage attenuation in the transmission signal on the repair line-L1, but in high-resolution The charging time of the pixel is short when the driving frequency is low or the driving frequency is high. At this time, due to the large delay and attenuation of the signal on the repair line-L1, the pixel voltage cannot be charged to the normal required level within the charging time of the pixel. The display of the disconnected data line is inconsistent with the normal data line, which leads to repair failure.

At present, the size of the LCD panel is getting larger and larger, and the repair line becomes longer and the resistance becomes larger, which leads to aggravated voltage attenuation on the repair line. In the traditional solution, the resistance is reduced by increasing the width of the repair line, but the increase in the width of the repair line will lead to interference with the signal line. The cross capacitance becomes larger, and after the cross capacitance becomes larger, repairing the signal transmission on the line will cause a longer delay, and the delay will cause the pixel voltage to not be fully charged at the end of the charging time. As the resolution increases and the driving frequency increases, the charging time will decrease accordingly. The traditional repair line overlaps with each data line, resulting in an increase in charging capacitance, and there is a long delay when transmitting signals on the repair line signal. , the final result is that the pixel voltage cannot be fully charged normally, and the picture is displayed as thin bright lines or thin dark lines, which will affect the display effect of the display panel.

Therefore, how to reduce the delay and attenuation of the data signal used for repair when it is transmitted on the repair line is a technical problem to be solved urgently by those skilled in the art.

Detailed ways

The specific implementation manners of the display panel provided by the embodiments of the present invention, its repairing method and the display device will be described in detail below with reference to the accompanying drawings.

An embodiment of the present invention provides a display panel, as shown in FIG. 2 and FIG. 3 , including: a plurality of data lines D located in the display area, a peripheral area located at one end of the data lines D and inputting data signals to each data line D A plurality of source driver chips, and a flexible circuit board PCB located in the peripheral area on the same side as the source driver chips;

Also includes: a first repair line B1, a plurality of second repair lines B2 and a third repair line B3; wherein,

As shown in FIG. 2 , the third repairing line B3 includes: a plurality of third line segments X3 located away from the display area of the source driver chip and intersecting with the data line D and insulated from each other; the data line D is divided into multiple groups, each The third line segment X3 corresponds to a group of data lines D; each third line segment X3 and each data line D in the corresponding group of data lines D have intersection areas and are insulated from each other, and the two ends of the third line segment X3 are respectively connected to the first A segment X1 has an intersection area and is insulated from each other;

or,

As shown in FIG. 3, the third repair line B3 includes: a fourth line segment X4 located away from the display area of the source driver chip and having a crossing area with each data line D and insulated from each other; Between the fifth line segment X5 parallel to the data line D; wherein, the two ends of the fourth line segment X4 and the first line segment X1 have an intersection area and are insulated from each other; one end of each fifth line segment X5 is connected to the fourth line segment X4, The other end has an intersecting area with the first line segment X1 and is insulated from each other.

In the above display panel provided by the embodiment of the present invention, the first repair line is arranged in the peripheral area so that it does not intersect with the data line, so that the line width of the first repair line can be adjusted, and the resistance of the first repair line can be reduced, thereby reducing the The voltage attenuation of the signal during transmission on the first repair line.

In addition, as shown in FIG. 2 , the third repair line is set as segmented third line segments, and each third line segment corresponds to a group of data lines, so that it can overlap with the data lines as little as possible. For example, as shown in Figure 2, one end of the data line where the signal interruption occurs is connected to the second line segment X2 in the intersection area, and the other end is connected to the third line segment X3 in the intersection area; according to the principle of proximity, one end of the third line segment X3 is connected to the first line Segment X1 is actually connected in the intersection area, and one end of the second line segment X2 is actually connected to the second repair line B2 in the intersection area according to the principle of proximity; thus, the data signal output by the source driver chip is divided into two paths, one of which goes directly along the data line D At the breakpoint, the other path reaches the flexible circuit board PCB through the second line segment X2 and the second repair line B2, and is amplified and output in the flexible circuit board PCB, and then transmitted to the first line segment X1 through the lead m, and then passes through the third line segment X3 is transmitted to the upper half of the data line D, thereby completing the repair of the data signal on the disconnected data line (the specific transmission path of the data signal used for repair is shown by the arrow in Figure 2);

Or as shown in Figure 3, one end of the data line where the signal interruption occurs is connected to the second line segment X2 in the intersection area, and the other end is connected to the fourth line segment X4 in the intersection area; according to the principle of proximity, the fourth line segment X4 and the data line The fifth line segment X5 at the actual connection place of D is connected with the first line segment X1 in the intersection area; one end of the fourth line segment X4 can also be connected with the first line segment X1 in the intersection area according to the principle of proximity; thus the output of the source driver chip The data signal is divided into two paths, one of which goes directly to the breakpoint along the data line D, and the other path reaches the flexible circuit board PCB through the second line segment X2 and the second repair line B2, and is amplified and output in the flexible circuit board PCB. m is transmitted to the first line segment X1, and then transmitted to the upper half of the data line D through the fifth line segment X5 and the fourth line segment X4, thereby completing the repair of the data signal on the broken data line (the data signal used for repair The specific transmission path shown in the arrow in Figure 3);

Specifically, in the above two repair methods, since the data signal is transmitted through the third line segment or through the fifth line segment and the fourth line segment, the intersection of the repair line and the data line can be avoided as much as possible, thereby reducing the delay of the data signal on the repair line. This ensures that the data signal can be charged to the corresponding pixel within a short charging time. It should be noted that the principle of proximity in the above embodiments means that the data signal can be transmitted to the opposite side of the source driver chip, that is, the upper half of the data line, via a shorter path.

During specific implementation, in the above-mentioned display panel provided by the embodiment of the present invention, as shown in FIG. 2, the third line segment X3 may be a U-shaped line segment, and the two ends of the U-shaped line segment may have intersection areas with the first line segment and be insulated from each other. , when a signal interruption occurs on the data line corresponding to the U-shaped line segment, one end of the U-shaped line segment can be selected to be connected to the first line segment in the intersection area. Specifically, at least two adjacent data lines may be divided into one group, and each group of data lines corresponds to a U-shaped line segment. When the data lines are divided into more groups and the number of data lines in each group is less, the corresponding third line segment, that is, the number of U-shaped line segments crossing the data line is less, so that the data signal on the repair line can be reduced more. Delay.

In specific implementation, in the above-mentioned display panel provided by the embodiment of the present invention, two adjacent data lines form a group, and a fifth line segment can be provided at the gap between the two data lines in each group of data lines; or At least three adjacent data lines form a group, and a fifth line segment is provided at a gap between two adjacent data lines in each group of data lines. Specifically, the number and position of the fifth line segment can be set according to actual needs, and the fifth line segment is used to connect the first line segment to the fourth line segment when repairing, so as to output the data signal on the first line segment to The upper half of the corresponding data line to complete the repair of the data signal. Therefore, it is only necessary to ensure that each data line can have a fifth line segment that can be connected to the first line segment in the intersection area when the signal is interrupted. Thus, the data signal on the first line segment is transmitted to the fourth line segment, and then transmitted to the corresponding data line through the fourth line segment. Of course, in order to reduce the intersection of the fourth line segment and the data line in the transmission path, some fifth line segments can be set as much as possible. For example, two adjacent data lines have been provided with a fifth line segment so far. The first line segment without crossing of the data line, then passes through the fifth line segment on the side of the broken data line, and outputs to the corresponding data line through the fourth line segment, which can minimize the intersection of the repair line and the data line. In this way, the delay of the data signal during transmission is minimized.

Based on the same inventive concept, an embodiment of the present invention provides a method for repairing the above-mentioned display panel provided by the embodiment of the present invention, as shown in FIG. 4 , which may specifically include:

S101. On the side close to the source driver chip, perform laser fusion on one end of the data line where signal interruption occurs and the second line segment in the intersection area, and perform laser fusion on one end of the second line segment and the second repair line in the intersection area;

S102. On the side away from the source driver chip, perform laser fusion on the other end of the data line where the signal interruption occurs and the corresponding third line segment in the intersection area, and perform laser fusion on one end of the third line segment and the first line segment in the intersection area Fusion;

or,

In the above repair method provided by the embodiment of the present invention, laser fusion is performed on one end of the data line where signal interruption occurs and the second line segment in the intersection area, and laser fusion is performed on one end of the second line segment and the second repair line in the intersection area according to the principle of proximity Fusion; for example, as shown in Figure 2, the other end of the data line where the signal is interrupted and the third line segment are laser fused in the intersection area; according to the principle of proximity, one end of the third line segment is laser fused with the first line segment in the intersection area; thus the source The data signal output by the drive chip is divided into two routes, one of which goes directly to the breakpoint along the data line, and the other reaches the flexible circuit board through the second line segment and the second repair line, and is amplified and output in the flexible circuit board, and transmitted through the lead wire to the first line segment, and then transmitted to the upper half of the data line through the third line segment, so as to complete the repair of the data signal on the broken data line;

Or as shown in Figure 3, the other end of the data line where the signal is interrupted and the fourth line segment are laser fused in the intersection area; according to the principle of proximity, the fifth line segment and the first line segment close to the actual connection between the fourth line segment and the data line Laser fusion is performed in the intersection area; thus, the data signal output by the source driver chip is divided into two paths, one of which goes directly to the breakpoint along the data line, and the other path reaches the flexible circuit board through the second line segment and the second repair line. After amplified output in the board, it is transmitted to the first line segment through the lead wire, and then transmitted to the upper half of the data line through the fifth line segment and the fourth line segment, thereby completing the repair of the data signal on the broken data line;

The delay on the repair line ensures that the data signal can be charged to the corresponding pixel within a short charging time. In addition, if two data lines have signal interruption faults at the same time, the above repair method can be used, one of which goes around half a circle from the left, and the other goes around half a circle from the right to complete the signal repair; When the signal is interrupted, it can be solved by increasing the number of first line segments, that is, setting multiple first line segments in parallel, and connecting each first line segment to the flexible circuit board through a lead wire, and then the above repair method can be used to repair at the same time Multiple data lines with a signal interruption.

In specific implementation, in the above-mentioned repairing method provided by the embodiment of the present invention, it may also include: on the side away from the source driver chip, crossing the end of the fourth line segment close to the laser fusion position with the data line and the first line segment The area is laser fused. Specifically, as shown in Figure 3, when the data signal used for repairing is transmitted to an end of the first line segment such as the right end shown in Figure 3 through the lead wire, the data signal can be transmitted to the first line segment laser through the first line segment The soft fifth line segment is then transmitted to the corresponding data line through the fourth line segment; at the same time, the right end of the fourth line segment can be laser fused with the first line segment, and when the data signal reaches the right end of the character line segment, it can also pass through the fourth line segment Direct transmission to the corresponding data line, so that the data signal can be quickly transmitted to the corresponding data line through two channels, and the charging rate can be improved.

Specifically, in order to reduce the attenuation and delay of the data signal on the repaired line, and to avoid signal interference with other signal lines during signal transmission, the path that the repaired signal can pass through but not used for repairing can be disconnected on the repaired line. . For example, as shown in FIG. 2 and FIG. 3 , the part between the position of the second line segment laser-fused with the data line and the end not laser-fused with the second repair line can be disconnected, which can reduce signal attenuation. In addition, as shown in Figure 2, the part between the end that is not laser fused with the first line segment on the third line segment and the laser fusion position with the data line can be disconnected; Laser fusion is performed on the right end of the three line segments, and the part between the laser fusion position of the third line segment and the first line segment to the left end on the first line segment can be disconnected; similarly, as shown in Figure 3, on the fourth line segment from The part between the laser fusion position with the data line and the left end can be disconnected, and the part between the laser fusion position with the fifth line segment and the left end on the first line segment can be disconnected.
