Currently, in a display panel of an electronic product, a data line is generally used to provide data signals for pixel circuits, and each data line can provide data signals for a plurality of pixel circuits on the same column. However, when a line break fault occurs at a certain position of a certain data line, for example, when the line break is caused by static electricity damage or particles on the surface of the substrate, in a column of pixel circuits corresponding to the data line, the pixel circuits after the line break fault position cannot receive the data signal due to the disconnection of the data line, so that the pixel circuits cannot realize normal light emission.

In order to solve the above technical problems, embodiments of the present application provide a variety of display panels, a data line open circuit repair method, and a display device. The following first describes a display panel provided in an embodiment of the present application.

Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present application. The display panel includes a substrate 1, the substrate 1 including a display region 10, the display region 10 including a plurality of pixel circuits 20. The plurality of pixel circuits 20 may be arranged in an array.

In the pixel circuit 20 arranged in an array, there are at least one group of two adjacent columns of pixels, and a plurality of first data lines 30 are disposed between the two columns of pixels. Each of the plurality of first data lines 30 may connect and control a portion of the pixel circuits 20 on the column. All pixel circuits 20 on the same column can be controlled by a plurality of first data lines 30 between two columns of pixels. It will be appreciated that one first data line 30 may be disposed between two adjacent columns of pixels, or a plurality of first data lines 30 may be disposed.

As shown in fig. 2, the display panel has a plurality of film layers, the substrate 1, the pixel circuit layer 2 and the light emitting layer 3 are located on different film layers, the pixel circuit layer 2 may include a plurality of film layers, and the pixel circuit 20 is disposed in the film layer corresponding to the pixel circuit layer 2. That is, the substrate 1 and the pixel circuit 20 are located in different film layers.

It will be appreciated that the display panel includes a plurality of pixel units, one pixel unit including sub-pixels of a plurality of colors, such as a red sub-pixel, a blue sub-pixel, and a red sub-pixel, as one pixel unit, and the plurality of display units collectively implement normal display of the display panel, wherein one sub-pixel is connected to one anode. The pixel circuit in the application can be used for driving one sub-pixel by one pixel circuit or driving a plurality of sub-pixels by one pixel circuit, namely the pixel circuit in the application can be driven by one or more.

The pixel circuit layer 2 includes a plurality of functional layers, such as an active layer 21, a gate layer 22, a source drain layer 23, and a plurality of insulating layers 11, an insulating layer 111 between the active layer and the gate layer, and an insulating layer 112 between the gate layer and the source drain layer 112. The light emitting layer includes an anode layer 311, a light emitting element 312, and a cathode layer 313. The display area 10 further includes connection lines 40 corresponding to the pixel circuits 20, and one connection line 40 may be connected to one pixel circuit 20 or may be connected to a plurality of pixel circuits 20 on the same column. That is, one connection line 40 is connected to at least one pixel circuit 20. The first data lines 30 and the connecting lines 40 in the display area 10 may be located in different layers, for example, at least one connecting line 40 and the plurality of first data lines 30 are located in different layers, i.e., any one of the plurality of first data lines 30 is not located in the same layer as the connecting line 40. The connection line 40 may be disposed to overlap at least two first data lines 30 in a direction perpendicular to a plane in which the substrate 1 is located, and electrically connected to at least one first data line 30 of the plurality of first data lines 30 where the overlap exists, so that the first data line 30 electrically connected receives a data signal and transmits the data signal to the pixel circuit 20.

When the connection line 40 and any one of the first data lines 30 are located in different layers, the connection line 40 and the first data line 30 may be electrically connected by providing a lead hole 90, and the lead hole 90 may be connected to the layer where the connection line 40 is located and the layer where the first data line 30 is located. It will be appreciated that the overlapping of the connection line 40 and the first data line 30 means that there is an overlapping position between the front projection of the connection line 40 on the substrate 1 and the front projection of the first data line 30 on the substrate 1, and the lead hole 90 may be disposed at the overlapping position, so as to electrically connect the connection line 40 and the first data line 30.

In the plurality of first data lines 30 between two adjacent columns of pixel circuits 20, when a disconnection fault occurs in one of the first data lines 30, the pixel circuits 20 connected to the first data line 30 after the disconnection fault location cannot receive the data signal transmitted by the first data line 30. Since each pixel circuit 20 is connected to the corresponding first data line 30 through the connection line 40, and each connection line 40 overlaps at least two first data lines 30. When the first data line 30 is broken and the data signal cannot be transmitted to the pixel circuit 20 through the connection line 40, the connection line 40 may be electrically connected to another first data line 30 having an overlap through a process of the display panel. As shown in fig. 3, when the connection line 40 is electrically connected to one of the plurality of first data lines 30 and the data line is broken, a lead hole 90 may be generated by laser processing at an overlapping position of the connection line 40 and the other first data lines 30 of the plurality of first data lines 30, where the lead hole 90 may be capable of communicating a film layer of the connection line 40 with a film layer of the other first data line 30, so as to electrically connect the connection line 40 with the other first data line 30. The pixel circuit 20 connected to the connection line 40 receives the data signal through the other first data line 30, thereby realizing the normal light emission of the pixel circuit 20. It will be appreciated that the other data line needs to overlap with the connecting line 40 so that the lead hole 90 connecting the two layers can be created by laser processing at the overlapping location.

In this embodiment, by providing the connection line 40 and at least two first data lines 30 to overlap in the direction perpendicular to the plane in which the substrate 1 is located, when the first data line 30 electrically connected to the connection line 40 has a disconnection fault, the connection line 40 can be connected to another first data line 30 having an overlap, so that when the connection line 40 is electrically disconnected from one first data line 30, the connection line 40 can be electrically connected to another first data line 30, so that the data signal sent by the first data line 30 is continuously received, and the pixel circuit 20 can receive the data signal through the connection line 40 and normally emit light, so as to implement the line defect repair function of the data line.

It can be understood that in a large-sized display panel, since more pixel circuits 20 are required for driving each first data line 30, the display effect is affected when displaying a low gray scale. By providing a plurality of first data lines 30 to drive the pixel circuits 30 in the same column, the number of the pixel circuits 20 driven by each first data line 30 can be reduced, so that the display effect of the display panel is prevented from being affected under low gray scale.

Referring to fig. 4, in some embodiments, each column of pixel circuits 20 may include a plurality of pixel circuit groups 50, and each pixel circuit group 50 includes a plurality of pixel circuits 20. The sum of the pixel circuits 20 in all the pixel circuit groups 50 is the same as the number of the pixel circuits 20 in the column. Each of the pixel circuit groups 50 may correspond to one of the plurality of first data lines 30. That is, all the pixel circuits 20 in the same pixel circuit group 50 are connected to the same first data line 30, and receive the data signals transmitted by the same first data line 30.

It is to be understood that, in the above embodiment, the number of the pixel circuit groups 50 may be one-to-one corresponding to the number of the first data lines 30, or may be greater than the number of the first data lines 30 or less than the number of the first data lines 30. When the number of the pixel circuit groups 50 is greater than the number of the first data lines 30, a plurality of pixel circuit groups 50 may be connected to the same first data line 30; and when the number of the pixel circuit groups 50 is smaller than the number of the first data lines 30, a part of the first data lines 30 may be not connected to the pixel circuits 20 in the pixel circuit groups 50.

In some embodiments, the plurality of pixel circuits 20 in the pixel circuit group 50 may be a plurality of pixel circuits 20 that are sequentially adjacent, that is, the plurality of pixel circuits 20 are sequentially connected in series to form one pixel circuit group 50, and no pixel circuits 20 belonging to other pixel circuit groups 50 exist between the first and the last pixel circuits 20.

It can be understood that the connection mode of the pixel circuits 20 and the first data lines 30 is designed such that a plurality of sequentially connected pixel circuits 20 are connected to the same first data line 30 as one pixel circuit group 50, so as to improve the production efficiency of the display panel.

In some embodiments, the number of each pixel circuit group 50 may be set equal among the plurality of pixel circuit groups 50. That is, one column of the sub-pixels is equally divided into a plurality of pixel circuit groups 50, and the number of the pixel circuits 20 in each pixel circuit group 50 is the same. It can be understood that when the plurality of first data lines 30 are provided to drive the column of sub-pixels, if each first data line 30 corresponds to one pixel circuit group 50, the number of the pixel circuits 20 required to be driven by each first data line 30 is equal, and at this time, the data signals output by each first data line 30 may also be set to be the data signals with the same waveforms, so that the data signals received by each pixel circuit 20 in the column of pixel circuits 20 are kept consistent, and the light emitting brightness of each pixel circuit 20 is also kept consistent.

When one of the plurality of first data lines 30 is disconnected and the pixel circuit 20 affected by the disconnection is connected to the other normal first data line 30 via the connection line 40, the number of pixel circuits 20 driven by the first data line 30 where the disconnection occurs decreases, and the number of pixel circuits 20 driven by the first data line 30 connected to the connection line 40 increases. Therefore, the light emission luminance of the pixel circuit 20, which is also capable of being normally driven by the first data line 30, which is disconnected, is also changed. For the first data line 30 connected by the connection line 40, when the number of connected pixel circuits 20 is low, the same first data line 30 can be connected; when the number of the connected pixel circuits 20 is relatively high and two or more normal first data lines 30, which are not disconnected, in the plurality of first data lines 30, the pixel circuits 20 to be connected to the first data lines 30 may be connected to each first data line 30 in an equalizing manner, so that the number of the pixel circuits 20 to be driven, which are added to each first data line 30, is relatively small, and the influence on the light-emitting brightness of the pixel circuits 20 due to the large increase of the number of the pixel circuits 20 driven by the first data lines 30 is avoided.

Referring to fig. 5, in some embodiments, the plurality of first data lines 30 may include at least one first backup data line 32 and at least one first main data line 31, the connection line 40 is connected to the first main data line 31 in a normal state, the first backup data line 32 is not electrically connected to the connection line 40, and the connection line 40 at least partially overlaps the first backup data line 32 in a direction perpendicular to the plane of the substrate 1.

In a normal state, the data signal is transmitted from the first main data line 31 to the pixel circuit 20 through the connection line 40, and when the first main data line 31 fails in an open circuit, the pixel circuit 20 which cannot receive the data signal can be electrically connected to the first backup data line 32 through the corresponding connection line 40. The pixel circuits 20 are now provided with data signals by the first back-up data lines 32. It is understood that the connection line 40 and the first backup data line 32 may be located in different layers, and the lead hole 90 communicating the two layers is formed by a laser process at a position where the connection line 40 and the first backup data line 32 overlap, so as to electrically connect the connection line 40 and the first backup data line 32, and the first backup data line 32 provides the data signal to the pixel circuit 20 through the connection line 40.

Referring to fig. 6, in some embodiments, the substrate 1 may include a photosensitive region 12 and a first display region 11, where the first display region 11 at least partially surrounds the photosensitive region 12. The connection line 40 includes a first connection line 41 and a second connection line 42, the first connection line 41 is located in the photosensitive region 12 and is correspondingly connected to the pixel circuit 20 of the photosensitive region 12, and the second connection line 42 is located in the first display region 11 and is correspondingly connected to the pixel circuit 20 of the first display region 11.

Between two adjacent columns of pixel circuits 20, a second data line 60 may be further disposed, where the pixel circuits 20 in the same column of the photosensitive area 12 are connected to the second data line 60 through a first connection line 41, and the pixel circuits 20 in the same column of the first display area 11 are connected to at least one first data line 30 through a second connection line 42.

It will be appreciated that the photosensitive area 12 may also be provided with an under-screen camera module to implement a camera function and a display function.

In the above embodiment, the second data line 60 can provide the data signal for the pixel circuits 20 in the same column in the photosensitive area 12 through the first connection line 41, and the first data line 30 can provide the data signal for the pixel circuits 20 in the same column in the first display area 11 through the second connection line 42. Since the photosensitive area 12 is usually disposed at the top of the display panel and the data lines transmit the data signals from the bottom to the top, the pixel circuit 20 of the photosensitive area 12 usually receives the data signals for a relatively long time and a relatively long lead time. The second data line 60 is used for outputting data signals to the pixel circuit 20 of the photosensitive area 12 independently, so that the data signals sent by the data line can be directly output to the pixel circuit 20 of the photosensitive device, the lead time is reduced, the situation that the thin film diode is not controlled to be conducted due to long lead time of the data signals when the pixel circuit 20 receives scanning signals is avoided, and the pulse width of the scanning signals of the pixel circuit 20 is improved.

In some embodiments, the second connection line 42 at least partially overlaps the second data line 60 in a direction perpendicular to a plane in which the substrate 1 is located, and the first connection line 41 at least partially overlaps the first data line 30.

In this embodiment, the second connection line 42 is electrically connected to the first data line 30, and may also at least partially overlap the second data line 60 in a direction perpendicular to the plane of the substrate 1, when the first data line 30 is broken and the second connection line 42 does not receive a data signal, the lead hole 90 may be generated by a laser process at a position where the second data line 60 overlaps the second connection line 42, so as to communicate the second connection line 42 with the second data line 60, so that the second connection line 42 can receive the data signal output by the second data line 60. That is, the second data line 60 may be used as a backup data line of the first display area 11, and the pixel circuit 20 of the first display area 11 is electrically connected to the first data line 30 through the second connection line 42 when the first data line 30 is in normal operation, and the pixel circuit 20 of the first display area 11 is electrically connected to the second data line 60 through the second connection line 42 when the first data line 30 is abnormal, so as to continuously receive the data signal, and realize normal light emission of the pixel circuit 20 of the first display area 11.

It should be noted that, when the second data line 60 is used as a backup data line of the first display area 11, the second data line 60 needs to pass through the photosensitive area 12 and the first display area 11, and at least partially overlap each second connection line 42 in the first display area 11 in a direction perpendicular to the plane of the substrate 1. Accordingly, if the second data line 60 is not used as a backup data line of the first display area 11, the second data line may extend from outside the display area 10 to the photosensitive area 12 around the first display area 11, so that the second data line does not need to pass through the first display area 11.

Similarly, based on the same principle, the first data line 30 may also be used as a backup data line of the photosensitive area 12, where the pixel circuit 20 of the photosensitive area 12 is electrically connected to the second data line 60 through the first connection line 41 when the second data line 60 is operating normally, and the pixel circuit 20 of the photosensitive area 12 is electrically connected to the first data line 30 through the first connection line 41 when the second data line 60 is abnormal, so as to continuously receive the data signal and realize normal light emission of the pixel circuit 20 of the photosensitive area 12. The first data line 30 is also required to pass through the first display area 11 and the photosensitive area 12 as a backup data line of the photosensitive area 12 so as to at least partially overlap with the first connection line 41. Accordingly, if the first data line 30 is not used as a backup data line of the photosensitive area 12, the first data line may not pass through the photosensitive area 12.

Referring to fig. 7 and 8, in some embodiments, the substrate 1 may further include a non-display area, a plurality of data signal terminals, a first connection lead 70, and a second connection lead 71.

The non-display area at least partially surrounds the first display area 11, and the non-display area includes a first non-display area 131, a second non-display area 132, and a binding area 133. Along the first direction, the first display area 11 is located between the binding area 133 and the photosensitive area 12, and the photosensitive area 12 is located between the first non-display area 131 and the first display area 11; the second non-display area 132 is located at two sides of the first display area 11 along the second direction;

the plurality of data signal terminals are located in the bonding area 133 and may include a first data signal terminal 80 and a second data signal terminal 81;

the first connection lead 70 is connected to the second data signal terminal 81 and connected to the second data line 60 from the bonding region 133 through the second non-display region 132 and the first non-display region 131;

the second connection lead 71 extends in a second direction intersecting the first direction, and the first connection lead 70 is connected to the second data line 60 through the second connection lead 71;

the first data line 30 is connected to the first data signal input terminal, and the first data line 30 extends from the bonding area 133 to the first non-display area 131 along the first direction.

In the above embodiment, as shown in fig. 7 and 8, the X direction is the first direction, and the Y direction is the second direction. The data signal terminal may be an output terminal of a Driver IC in the display panel. The driving chip can output corresponding data signals through the data signal terminal. The first data signal terminal 80 may transmit a data signal to the first data line 30, and the first data line 30 may extend from the bonding area 133 to the first non-display area 131 in the first direction and be connected to the pixel circuits 20 of the same column while passing through the display area 10 so that the pixel circuits 20 receive the data signal.

The second data signal terminal 81 may transmit a data signal to the first connection lead 70, the first connection lead 70 may transmit the data signal to the second connection lead 71, the second connection lead 71 may transmit the data signal to the second data line 60, and the second data line 60 may transmit the data signal to the pixel circuit 20 in the photosensitive region 12.

Since the photosensitive area 12 is generally disposed at the top of the display panel and the direction of the data line for transmitting the data signal is from bottom to top, the pixel circuit 20 of the photosensitive area 12 is at the end of the data line, and the time for receiving the data signal is generally relatively later and the pre-time is relatively longer. The second data line 60 is used for outputting data signals to the pixel circuit 20 of the photosensitive area 12 independently, so that the data signals sent by the data line can be directly output to the pixel circuit 20 of the photosensitive device, the lead time is reduced, the situation that the thin film diode is not controlled to be conducted due to long lead time of the data signals when the pixel circuit 20 receives scanning signals is avoided, and the pulse width of the scanning signals of the pixel circuit 20 is improved. And the first connection lead 70 and the second connection lead 71 are used for winding, so that the data signal sent by the second data signal end 81 is directly connected with the second data line 60 by winding the non-display area to the outer side of the photosensitive area 12, the number of wires in the display area 10 can be reduced, the light transmission area of the display panel can be increased, signal interference with other signal lines in the display area 10 can be avoided, and the stability of the data signal received by the pixel circuit 20 of the photosensitive area 12 is improved.

Referring to fig. 9, in the embodiment shown in fig. 8, the second data line 60 may further extend to the first display area 11 after passing through the photosensitive area 12, and at least partially overlap with the second connection line 42 in the first display area 11 in a direction perpendicular to the plane of the substrate 1. When the first data line 30 is disconnected, the second data line 60 may be used as a backup data line of the first data line 30, and the electrical connection between the second data line 60 and the second connection line 42 is achieved through laser drilling.

Similarly, the first data line 30 may also extend to the photosensitive region 12 after passing through the first display region 11, and at least partially overlap with the first connection line 41 in the photosensitive region 12 in a direction perpendicular to the plane of the substrate 1. I.e. the first data line 30 may also serve as a backup data line for the second data line 60.

It is understood that the first connection lead 70 may also be disposed to extend from the bonding region 133 to the first non-display region 131 in the first direction, i.e., not pass through the second non-display region 132.

Fig. 10 is a schematic flow chart of a method for repairing broken data line according to an embodiment of the present application. The method comprises the following steps:

s910, performing anomaly detection on the first data line in the display panel to determine the first data line with the disconnection; wherein the display panel is the display panel;

s920, determining a pixel circuit which does not receive a data signal according to the first data line with the disconnection;

and S930, performing laser drilling and forming a lead hole on the connecting wire corresponding to the pixel circuit which does not receive the data signal so as to conduct the connecting wire corresponding to the pixel circuit which does not receive the data signal with the first data wire which does not generate disconnection.

In this embodiment, after the display panel is manufactured, it is necessary to perform abnormality detection before shipment to repair the display panel in which abnormality is detected.

In S910, when abnormality detection is performed on the first data line in the display panel, whether or not the first data line is disconnected can be determined by whether or not the pixel circuit connected to the first data line can normally receive the data signal. It will be appreciated that the first data line where the circuit break occurs may be a first data line between two columns of pixel circuits, and the number may be one or more.

In S920, the first data line with the open circuit and the specific position of the open circuit can be determined according to the first data line with the open circuit, the pixel circuit which can normally receive the data signal and display the light emission, and the pixel circuit which can not normally receive the data signal and display the light emission. For example, a pixel circuit connected to the first data line before a certain pixel circuit can normally receive a data signal, but all pixel circuits after the pixel circuit cannot normally receive a data signal, and then the open circuit position of the first data line is between the pixel circuit and the previous pixel circuit.

In S930, after determining the pixel circuit that cannot receive the data signal due to the disconnection of the first data line, drilling may be performed on the connection line corresponding to the pixel circuit by a laser process to generate a lead hole connecting the two film layers. The lead hole may be disposed at a position where the connection line overlaps with other first data lines in a direction perpendicular to a plane in which the substrate is located, and the lead hole may communicate the connection line and the first data line located in different film layers at the position, so that the connection line may be electrically connected again with the first data line where disconnection does not occur.

In this embodiment, the display panel is the display panel in the above embodiment, and the connection lines in the display panel can overlap with at least two first data lines in a direction perpendicular to the plane in which the substrate is located. When the first data line is subjected to open circuit detection, for the pixel circuit which cannot receive the data signal due to open circuit, lead holes which are communicated with two film layers are formed through laser drilling at the overlapped positions of the connecting line and the other normal first data line, so that the connecting line is electrically connected with the normal first data line, and the pixel circuit can receive the data signal through the other normal first data line to realize normal luminescence of the pixel circuit. Through setting up the connecting wire and having the overlap with many first data lines, can be when detecting that first data line takes place the broken string, communicate this connecting wire with other normal first data lines, realize display panel's line defect repair function.
