[0042] The light shielding layer 30 is located on the side of the protective layer 20 close to the touch layer 12 and is arranged corresponding to the position of the non-display area NA. When the protective layer 20 includes multiple layers, the light shielding layer 30 can also be located between two adjacent layers of the multiple layers of the protective layer 20. The light shielding layer 30 is used to shield the non-display area NA of the display module 100, that is, to shield the edge area of the display module 100, so as to avoid light leakage of the edge area of the display module 100.

[0044] With reference to Figure 4 , Figure 5 and Figure 6 As shown in Figure 5 , the touch layer 12 includes a plurality of first touch electrodes 121 and first touch wires 122 connected to the corresponding first touch electrodes 121. The first touch electrodes 121 are located in the display area AA, and the first touch wires 122 are located in the non-display area NA. The extension directions of the first touch electrodes 121 and the first touch wires 122 are different. A plurality of first touch electrodes 121 are arranged at intervals in the first direction X and are arranged corresponding to the display area AA. Each first touch electrode 121 extends along the second direction Y. The second direction Y and the first direction X are different, such as the second direction Y and the first direction X intersecting at an angle greater than 0 degrees and less than or equal to 90 degrees. For example, the first direction X is the row direction, the second direction Y is the column direction, and the first direction X and the second direction Y are perpendicular.

[0045] The first touch wires 122 extend along the first direction X and are arranged in the non-display area NA. Specifically, the first touch wires 122 are arranged in the first non-display area NA1 and connected to the corresponding first touch electrodes 121. Each of the first touch electrodes 121 includes at least two first sub-electrodes 1211 arranged in the first direction X and extending along the second direction Y.

[0046] The first touch wires 122 are connected to the at least two first sub-electrodes 1211, i.e., each of the first touch wires 122 is connected to all the first sub-electrodes 1211 on the first touch electrode 121. In other words, each of the first touch wires 122 connects all the first sub-electrodes 1211 on the first touch electrode 121 in parallel, so that all the first sub-electrodes 1211 on the first touch electrode 121 have the same signal and the impedance on the first touch electrode 121 can be reduced.

[0047] Optionally, each of the first touch electrodes 121 includes three first sub-electrodes 1211 arranged in the first direction X, and each of the first touch wires 122 is connected to three first sub-electrodes 1211. In the top view of the display module 100, the first touch wires 122 are located between the light-shielding layer 30 and the display area AA, as shown in Figure 3 The first touch wires 122 are multiplexed as precision marks for cutting edge precision detection. Since the first touch wires 122 are not blocked by the light-shielding layer 30, the first touch wires 122 can be used as precision marks for the AOI equipment to detect the cutting precision of the cutting edge, so as to solve the problem that the existing AOI equipment cannot capture the precision marks through the light-shielding layer 30.

[0048] Continuing to refer to Figure 5 The touch layer 12 further includes a plurality of second touch electrodes 123 intersecting and insulated from the first touch electrodes 121 and second touch wires connected to the corresponding second touch electrodes 123. The second touch electrodes 123 and the first touch electrodes 121 are intersected and insulated from each other in the top view of the display module 100. The second touch electrodes 123 and the first touch electrodes 121 can be arranged in the same layer or different layers. The embodiments of the present application take the case that the second touch electrodes 123 and the first touch electrodes 121 are arranged in the same layer as an example.

[0049] Specifically, the touch layer 12 can include a first conductive layer and a second conductive layer, an interlayer insulating layer is arranged between the first conductive layer and the second conductive layer, and the second conductive layer is located on a side of the first conductive layer away from the display layer 11. The first touch electrode 121 and the second touch electrode 123 are both located on the second conductive layer, and one of the first touch electrode 121 and the second touch electrode 123 is bridged by the first conductive layer at a position where the first touch electrode 121 and the second touch electrode 123 intersect.

[0050] The plurality of second touch electrodes 123 are arranged at intervals in the second direction Y and correspond to the display area AA, and each of the second touch electrodes 123 extends along the first direction X. The second touch wires extend along the second direction Y and correspond to the non-display area NA. In a top view of the display module 100, part of the second touch wires is located between the light shielding layer 30 and the display area AA. Part of the second touch wires located between the light shielding layer 30 and the display area AA is multiplexed as precision Mark for cutting edge precision detection.

[0051] It should be noted that, Figure 5 To Figure 4 the partial detail view in FIG. 1C, so Figure 5 the second touch wires located in the second non-display area NA2 and / or the third non-display area NA3 are not shown in FIG. 1C. A plurality of second touch wires can be placed in the second non-display area NA2 and / or the third non-display area NA3, and the plurality of second touch wires are arranged at intervals in the first direction X. The second touch wires differ from the first touch wires 122 in that the second touch wires are connected between the second touch electrodes 123 and a touch driving chip, each second touch electrode 123 corresponds to one of the second touch wires, and the touch driving chip can be arranged in the fourth non-display area NA4; while the first touch wires 122 are used to connect all first sub-electrodes 1211 on the same first touch electrode 121, but do not connect the touch driving chip.

[0052] Of course, the touch layer 12 can also include third touch wires and fourth touch wires arranged in the fourth non-display area NA4, the third touch wires are arranged correspondingly with the first touch wires 122 and are used to connect all first sub-electrodes 1211 on the same first touch electrode 121. The fourth touch wires are connected between the third touch wires and / or the first sub-electrodes 1211 and the touch driving chip.

[0053] In some embodiments, the display panel 10 adopts mutual-capacitance touch control, one of the first touch electrode 121 and the second touch electrode 123 is a touch driving electrode, and the other is a touch sensing electrode. The touch driving chip provides a touch driving signal to the touch driving electrode and receives a sensing signal returned by the touch sensing electrode, and determines the position of the capacitor where the capacitance value changes according to the sensing signal, so as to determine the touch position.

[0054] In other embodiments, the display panel 10 can also adopt self-capacitance touch control, for example, the first touch electrode 121 and the second touch electrode 123 form a capacitor with the ground, respectively, and the touch driving chip detects the detection signal returned by the first touch electrode 121 and the second touch electrode 123, respectively, to determine the change of the ground capacitance of each electrode before and after touch, so as to determine the touch position.

[0055] Referring to Figure 6 , the first touch electrode 121 and the second touch electrode 123 are both arranged in a metal grid shape, and the metal grid of the first touch electrode 121 is arranged to be disconnected with the metal grid of the second touch electrode 123. The display layer 11 includes a plurality of sub-pixels 111, each of which is arranged to correspond to one mesh of the metal grid, that is, each mesh of the metal grid is provided with one sub-pixel 111. The plurality of sub-pixels 111 can include red sub-pixels 111, green sub-pixels 111, and blue sub-pixels 111.

[0056] The first touch wire 122 is connected with the metal grid of the first touch electrode 121, and the first touch wire 122 has a first interval 1220 between two adjacent first touch wires 122. The first interval 1220 is used to separate two adjacent first touch electrodes 121 to avoid short circuit between the two adjacent first touch electrodes 121. However, the existence of the first interval 1220 makes each first touch wire 122 discontinuous, that is, intermittent, which will cause the precision Mark image captured by the AOI device to be intermittent, thereby possibly causing the capture to fail.

[0057] In order to improve the success rate of capturing the precision Mark by the AOI device, some improvement schemes are provided in embodiments of the present application. In some embodiments, referring to Figure 7 , Figure 7 is a partial structure diagram of the touch layer 12 provided by the embodiments of the present application, and Figure 6The difference of the example touch layer 12 is that the touch layer 12 further comprises a first redundant trace 124, which has the same extension direction as the first touch trace 122 and is arranged corresponding to the position of the first interval 1220. The first redundant trace 124 cooperates with the first touch trace 122 to form a substantially continuous precision Mark, avoiding the precision Mark captured by the AOI device to be discontinuous and thus causing the capture failure, thereby improving the success rate of the AOI device capturing the precision Mark.

[0058] Specifically, in the first direction X, the first redundant trace 124 is arranged alternately with the first touch trace 122, that is, each first redundant trace 124 is located between two adjacent first touch traces 122, and each first touch trace 122 is located between two adjacent first redundant traces 124. The first redundant trace 124 is arranged in an interval with the adjacent first touch trace 122, and the first redundant trace 124 is arranged in an interval with the first touch electrode 121 and the second touch electrode 123, so that the first redundant trace 124 is insulated from the adjacent first touch trace 122, the first touch electrode 121 and the second touch electrode 123. That is, the first redundant trace 124 is in a floating state, and no signal is input to the first redundant trace 124. Optionally, the line width of the first redundant trace 124 is the same as the line width of the first touch trace 122.

[0059] Optionally, the first redundant trace 124 and the first touch trace 122 are arranged in the same layer and in the same line, for example, the first redundant trace 124 and the first touch trace 122 are both located in the second conductive layer. The first redundant trace 124 and the first touch trace 122 are located on the same straight line, or the first redundant trace 124 and the first touch trace 122 at least partially overlap in the first direction X. In the first direction X, the length of the first redundant trace 124 is less than the length of the first interval 1220 and less than the length of the first touch trace 122, so as to avoid the first redundant trace 124 from short-circuiting with the adjacent first touch trace 122.

[0060] However, it should be noted that the gap between the first redundant trace 124 and the adjacent first touch trace 122 needs to be controlled to be as small as possible to avoid affecting the continuity of the first touch trace 122 and the first redundant trace 124 as a whole, for example, the gap between the first redundant trace 124 and the first touch trace 122 satisfies the minimum gap that can avoid short-circuiting between them.

[0061] In some embodiments, the first redundant trace 124 and the first touch trace 122 are arranged in different layers, for example, the first redundant trace 124 is arranged in the first conductive layer, and the first touch trace 122 is arranged in the second conductive layer. In the top view of the display module 100, the first redundant trace 124 and the first touch trace 122 are arranged on the same straight line, or the first redundant trace 124 and the first touch trace 122 at least partially overlap in the first direction X.

[0062] In the first direction X, the length of the first redundant trace 124 is greater than or equal to the length of the first interval 1220 and less than the length of the first touch trace 122. At this time, since the first redundant trace 124 and the first touch trace 122 are arranged in different layers, the first redundant trace 124 with a relatively large length can be arranged, so that the length of the first redundant trace 124 is greater than the length of the first interval 1220, and the first redundant trace 124 and the first touch trace 122 are completely continuous, thereby further improving the success rate of the AOI equipment grabbing precision Mark.

[0063] When the length of the first redundant trace 124 is greater than the length of the first interval 1220, the orthographic projection of the first redundant trace 124 on the display layer 11 and the orthographic projection of the first touch trace 122 on the display layer 11 will have an overlapping part. In order to reduce the overlapping length of the first redundant trace 124 and the first touch trace 122 and avoid affecting the touch performance due to the overlapping of the two, the length of the first redundant trace 124 can be less than the length of the first touch trace 122.

[0064] In some embodiments, each of the first redundant traces 124 arranged between two adjacent first touch traces 122 can be designed in multiple segments, for example, each of the first redundant traces 124 can include a plurality of first sub-traces arranged at intervals in the first direction X, and the gap between two adjacent first sub-traces can be less than or equal to the gap between the first redundant trace 124 and the first touch trace 122.

[0065] In some embodiments, continuing to refer to Figure 6 and Figure 7 , the display panel 10 further includes a shielding electrode line 13 and a redundant electrode pattern 14. The shielding electrode line 13 is arranged on the side of the first touch trace 122 away from the first touch electrode 121. The shielding electrode line 13 is used to shield interference signals to avoid affecting the touch performance of the touch layer 12. The line width of the shielding electrode line 13 is greater than the line width of the first touch trace 122.

[0066] The redundant electrode pattern 14 is located on the side of the shielding electrode away from the first touch trace 122. The redundant electrode pattern 14 is used to cooperate with the light-shielding layer 30 to shield the edge of the display module 100 and reduce reflectivity. The redundant electrode pattern 14 includes a plurality of spaced sub-electrode patterns, which are arranged in rows in the first direction X. Adjacent rows of sub-electrode patterns are staggered, that is, the sub-electrode patterns on each row correspond to the gap between two adjacent sub-electrode patterns on the adjacent row.

[0067] In this configuration, at least one of the shielded electrode line 13 and the redundant electrode pattern 14 is located in the touch layer 12 or the display layer 11. For example, the shielded electrode line 13 is located in the touch layer 12, and the redundant electrode pattern 14 is located in the display layer 11.

[0068] Optionally, the display panel 10 further includes a ground line 15 and a crack detection line 16. The ground line 15 is located on the side of the redundant electrode pattern 14 away from the shielding electrode line 13, and the crack detection line 16 is located on the side of the ground line 15 away from the redundant electrode pattern 14. The crack detection line 16 is used to detect whether a crack appears at the functional hole HA position.

[0069] In some embodiments, refer to Figure 8 , Figure 8 This is a schematic diagram of another partial structure of the touch layer 12 provided in an embodiment of the present invention, and... Figure 7 The difference in the example touch layer 12 is that the first redundant trace 124 and the first touch trace 122 have the same line width, and the line width of the first touch trace 122 is greater than 30 micrometers, such as 31 micrometers, 32 micrometers, 33 micrometers, 36 micrometers, 40 micrometers, 45 micrometers, 50 micrometers, 60 micrometers, 70 micrometers, 80 micrometers, 90 micrometers, 100 micrometers, etc.
