[0054] Organic Light Emitting Diode (OLED) display technology is regarded as the most promising new flat panel display technology of the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low energy consumption, low cost, self-illumination, wide viewing angle and fast response speed.

[0055] In the process of implementing the present application, the inventor found that the following problems exist in the related art: the display panel includes a grid-shaped touch layer and a plurality of light-emitting units, the touch layer encloses to form a plurality of openings, the plurality of openings are arranged corresponding to the plurality of light-emitting units, and the orthographic projection of the light-emitting units on the substrate is located within the orthographic projection of the corresponding openings on the substrate. The touch layer includes a plurality of touch electrode blocks arranged in multiple rows and multiple columns, at least one column of breaks is arranged between two adjacent touch electrode blocks along the row direction, one column of breaks includes a plurality of breaks arranged along the column direction, and one column of breaks is arranged along a straight line.

[0056] However, since one column of breaks is arranged along a straight line, the arrangement of one column of breaks is relatively dense, and the reflection difference between the position without breaks and the position with breaks of the touch routing is large, forming a "square"-shaped bright spot under strong light irradiation, thereby affecting the display effect of the display panel.

[0057] In view of at least one of the above problems, embodiments of this application provide a display panel and a display device that can improve the display effect of the display panel.

[0058] The following will combine Figures 1-7 The display panel and display device provided in the embodiments of this application will be described.

[0059] This application provides a display device, which may include a display panel 100. The display device may be an electronic paper device, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, smart bracelet, smartwatch, supercomputer, navigator, wireless device, personal digital assistant (PDA), handheld or portable computer, GPS receiver / navigator, camera, MP4 video player, camcorder, game console, clock, calculator, television monitor, computer monitor, automotive display (e.g., odometer display), cockpit controller and / or display, camera view display (e.g., display of a rearview camera in a vehicle), electronic billboard or sign, projector, and other mobile or fixed terminals.

[0060] For example, the display panel 100 can be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light-emitting diode (LED) display panel, a quantum dot light-emitting diode (QLED) display panel, a mini light-emitting diode (MiniLED) display panel, a micro light-emitting diode (Micro LED) display panel, or a liquid crystal display (LCD) display panel, etc. This application uses an OLED display panel as an example for illustration.

[0061] The display panel 100 provided in the embodiments of this application will be described below.

[0062] See Figure 1 and Figure 4This application provides a display panel 100, which may include a substrate 140. The substrate 140 provides support for subsequent film layers. The display panel 100 may include a touch layer 101, which is disposed on one side of the substrate 140 and can be used to implement the touch function of the display panel 100. The touch layer 101 forms a plurality of openings 115. The display panel 100 may include a plurality of light-emitting units, which are disposed on the side of the substrate 140 facing the touch layer 101, and the plurality of light-emitting units are correspondingly disposed with respect to the plurality of openings 115. The orthographic projection of the light-emitting unit on the substrate 140 is located within the orthographic projection of the corresponding opening 115 on the substrate 140, thereby reducing the light occlusion of the light-emitting unit by the touch layer 101.

[0063] In this embodiment, the correspondence between A and B can refer to one A corresponding to at least one B, or one B corresponding to at least one A. This embodiment uses the example of one A corresponding to one B. Similarly, the correspondence between a light-emitting unit and an opening 115 can refer to one light-emitting unit corresponding to at least one opening 115, or one opening 115 corresponding to at least one light-emitting unit. This embodiment uses the example of one opening 115 corresponding to one light-emitting unit.

[0064] See Figure 4 The touch layer 101 includes a plurality of touch electrode blocks 110 arranged along a plane parallel to the substrate 140. At least one break group 120 is provided between two adjacent touch electrode blocks 110, and the break group 120 includes a plurality of breaks 121. In the two adjacent touch electrode blocks 110 and the at least one break group 120 located between the two adjacent touch electrode blocks 110, the at least one break group 120 includes a first break group 120a, which can cut off the two adjacent touch electrode blocks 110. In the two adjacent touch electrode blocks 110 and the first break group 120a located between the two adjacent touch electrode blocks 110, the sidewall of the break 121 of the first break group 120a is constructed as part of the outer peripheral sidewall of the touch electrode block 110, that is, the first break group 120a is the break group 120 closest to the touch electrode block 110. The line formed by fitting the centerlines of multiple fractures 121 in the first fracture group 120a is the fifth line S5. Figure 6), the fifth line S5 is a broken line or a curve. In this way, the plurality of fractures 121 in the first fracture group 120a are arranged along the broken line or curve, so that the distance between two adjacent fractures 121 in the first fracture group 120a is relatively long, the plurality of fractures 121 in the first fracture group 120a are arranged relatively dispersedly, which reduces the observability of the plurality of fractures 121 in the first fracture group 120a, can weaken the "mouth"-shaped bright spot formed on the display panel 100 under strong light irradiation, thereby improving the display effect of the display panel 100. In addition, compared with the related art in which the plurality of fractures 121 in the first fracture group 120a are arranged along a straight line, the embodiments of the present application only change the arrangement manner of the plurality of fractures 121 in the first fracture group 120a, there is no need to change the area of the touch electrode blocks 110, nor the number of the touch electrode blocks 110, so that the capacitance fluctuation of the touch electrode blocks 110 is small, power consumption will not be increased, which is beneficial for the touch electrode blocks 110 to meet the capacitance specification, and ensures the sensitivity and accuracy of touch control.

[0065] Wherein, refer to Figure 6 , the fifth line S5 jointly fitted by the center lines of the plurality of fractures 121 in the first fracture group 120a may cover at least part of the center line of each fracture 121 in the first fracture group 120a. Neither the center lines nor the lines (such as the fifth line) are real existing structures, and both are virtual lines. The distance between the center line of the fracture 121 of the first fracture group 120a and the first side wall 1211 is equal to the distance between the center line of the fracture 121 of the first fracture group 120a and the second side wall 1212.

[0066] In some embodiments, refer to Figure 5, in two adjacent touch electrode blocks 110 and a first fracture group 120a located between the two adjacent touch electrode blocks 110, the fracture 121 of the first fracture group 120a includes a first sidewall 1211 and a second sidewall 1212 disposed opposite to each other, the first sidewall 1211 is disposed close to one touch electrode block 110, the second sidewall 1212 is disposed close to the other touch electrode block 110, the first sidewalls 1211 of the plurality of fractures 121 of the first fracture group 120a jointly fit a first line S1, the second sidewalls 1212 of the plurality of fractures 121 of the first fracture group 120a jointly fit a second line S2, and at least one of the first line S1 and the second line S2 is a polyline or a curve. For example, the first line S1 is a polyline or a curve, such that the distance between two adjacent first sidewalls 1211 in the first fracture group 120a is relatively large, the plurality of first sidewalls 1211 in the first fracture group 120a are arranged relatively dispersedly, the observability of the fractures 121 at the plurality of first sidewalls 1211 in the first fracture group 120a is reduced, the square-shaped bright spots of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100. For another example, the second line S2 is a polyline or a curve, such that the distance between two adjacent second sidewalls 1212 in the first fracture group 120a is relatively large, the plurality of second sidewalls 1212 in the first fracture group 120a are arranged relatively dispersedly, the observability of the fractures 121 at the plurality of second sidewalls 1212 in the first fracture group 120a is reduced, the square-shaped bright spots of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100.

[0067] In some embodiments, refer to Figure 5 , the first line S1 and the second line S2 are parallel. In this way, the arrangement manner of the plurality of first sidewalls 1211 in the first fracture group 120a and the plurality of second sidewalls 1212 in the first fracture group 120a is relatively consistent, which can reduce the manufacturing difficulty of the plurality of fractures 121 of the first fracture group 120a.

[0068] In other embodiments, the first line S1 and the second line S2 are not parallel. In this way, when the first line S1 and the second line S2 are not parallel, the distribution of the fractures 121 is more irregular compared with the case where they are parallel. Under strong light irradiation, due to the irregularity of the distribution of the fractures 121, the shape of the square-shaped bright spots that might otherwise be formed due to the relatively regular distribution of the fractures 121 will be disrupted. Such irregular bright spots are visually less perceptible than regular square-shaped bright spots, because the human eye is more sensitive to regular patterns, which can further weaken the influence of bright spots on the display effect.

[0069] In some embodiments, refer to Figure 3The break group 120 between two adjacent touch electrode blocks 110 is one, and is the first break group 120a. The first sidewall 1211 of the multiple breaks 121 of the first break group 120a is constructed as the outer peripheral sidewall of the first touch electrode block 110a, and the second sidewall 1212 of the multiple breaks 121 of the first break group 120a is constructed as the outer peripheral sidewall of the second touch electrode block 110b. No first structure 131 is provided between two adjacent touch electrode blocks 110.

[0070] In some embodiments, see Figure 4 The touch layer 101 includes a first structure 131 disposed between two adjacent touch electrode blocks 110. Multiple break groups 120 exist between the two adjacent touch electrode blocks 110, defining the two adjacent touch electrode blocks 110 as a first touch electrode block 110a and a second touch electrode block 110b. In the first structure 131 located between the two adjacent touch electrode blocks 110, the multiple break groups 120 between the first touch electrode blocks 110a and the second touch electrode blocks 110b include two first break groups 120a. One first break group 120a is located between the first structure 131 and the first touch electrode block 110a, and this first break group 120a can sever the first structure 131 and the first touch electrode block 110a. Another first break group 120a is located between the first structure 131 and the second touch electrode block 110b, and this other first break group 120a can cut off the first structure 131 and the second touch electrode block 110b.

[0071] For example, both the touch electrode block 110 and the first structure 131 can be mesh-like.

[0072] In some embodiments, the first structure 131 is configured as at least one of a touch lead and a virtual electrode.

[0073] For example, at least a portion of the first structure 131 is configured as a touch lead, the display panel 100 includes a touch chip, and the touch electrode block 110 and the touch chip are connected by touch leads. The touch leads can connect the touch chip and the touch electrode block 110 to realize signal transmission between the touch chip and the touch electrode block 110.

[0074] For example, at least a portion of the first structure 131 is configured as a virtual electrode, and the virtual electrode and the touch electrode block 110 are insulated from each other. In this way, by setting the virtual electrode, it can be ensured that the display of the display panel 100 in the area where the touch electrode block 110 is set and the display panel 100 in the area where the virtual electrode is set are more consistent, thereby improving the display uniformity of the display panel 100.

[0075] In some embodiments, see Figure 4, among two adjacent touch electrode blocks 110 and the first structure 131 located between the two adjacent touch electrode blocks 110, the first structure 131 includes a plurality of sub-structures 1311, the plurality of sub-structures 1311 are arranged along the direction from the first touch electrode block 110a to the second touch electrode block 110b, the plurality of fracture groups 120 between the first touch electrode block 110a and the second touch electrode block 110b include a second fracture group 120b, the second fracture group 120b is disposed between two adjacent sub-structures 1311, and the centerlines of the plurality of fractures 121 in the second fracture group 120b jointly fit a sixth line S6 ( Figure 6 ), and the sixth line S6 is a broken line or a curve. In this way, the line jointly fitted by the centerlines of the plurality of fractures 121 in the second fracture group 120b is a broken line or a curve, so that the distance between two adjacent fractures 121 in the second fracture group 120b is relatively long, the plurality of fractures 121 in the second fracture group 120b are arranged relatively dispersedly, the observability of the plurality of fractures 121 in the second fracture group 120b is reduced, the "square" shaped bright spot of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100.

[0076] In some embodiments, the curve includes an arc, the reflection direction of light on the side wall of the fracture 121 will continuously change with the curvature of the arc, the side wall of the fracture 121 will not make the light reflect intensively to a specific direction to form an obvious bright spot, so that the reflected light is dispersed in a relatively large angle range, the intensity and visibility of the bright spot are reduced, thereby improving the display effect of the display panel 100 under strong light.

[0077] In some embodiments, refer to Figure 4 and Figure 5, in two adjacent touch electrode blocks 110 and the second fracture group 120b located between the two adjacent touch electrode blocks 110, the fractures 121 of the second fracture group 120b include a third side wall 1213 and a fourth side wall 1214 disposed opposite to each other. The third side walls 1213 of the multiple fractures 121 of the second fracture group 120b jointly fit to form a third line S3, and the fourth side walls 1214 of the multiple fractures 121 of the second fracture group 120b jointly fit to form a fourth line S4. At least one of the third line S3 and the fourth line S4 is a polyline or a curve. For example, the third line S3 is a polyline or a curve, so that the distance between two adjacent third side walls 1213 in the second fracture group 120b is relatively long, and the multiple third side walls 1213 in the second fracture group 120b are arranged in a relatively dispersed manner, which reduces the observability of the fractures 121 at the multiple third side walls 1213 in the second fracture group 120b, can weaken the "square"-shaped bright spot of the display panel 100 under strong light irradiation, thereby improving the display effect of the display panel 100. For another example, the fourth line S4 is a polyline or a curve, so that the distance between two adjacent fourth side walls 1214 in the second fracture group 120b is relatively long, and the multiple fourth side walls 1214 in the second fracture group 120b are arranged in a relatively dispersed manner, which reduces the observability of the fractures 121 at the multiple fourth side walls 1214 in the second fracture group 120b, can weaken the "square"-shaped bright spot of the display panel 100 under strong light irradiation, thereby improving the display effect of the display panel 100.

[0078] In some embodiments, the third line S3 and the fourth line S4 are parallel, such that the arrangement manners of the multiple third side walls 1213 in the second fracture group 120b and the multiple fourth side walls 1214 in the second fracture group 120b are relatively consistent, which can reduce the manufacturing difficulty of the multiple fractures 121 of the second fracture group 120b.

[0079] In other embodiments, the third line S3 and the fourth line S4 are not parallel, which can further weaken the influence of bright spots on the display effect, the principle of which has been described and will not be repeated here.

[0080] In some embodiments, at least one of the first line S1 and the second line S2 is parallel to at least one of the third line S3 and the fourth line S4, such that the arrangement manner of at least one of the first side walls 1211 in the first fracture group 120a and the second side walls 1212 in the first fracture group 120a is relatively consistent with that of at least one of the third side walls 1213 in the second fracture group 120b and the fourth side walls 1214 in the second fracture group 120b, which can reduce the manufacturing difficulty of the first fracture group 120a and the second fracture group 120b.

[0081] In other embodiments, at least one of the first line S1 and the second line S2 is not parallel to at least one of the third line S3 and the fourth line S3. In this way, the influence of bright spots on the display effect can be further weakened, and the principle thereof has been described, which will not be repeated here.

[0082] In some embodiments, refer to Figure 1 and the display panel 100 includes an array layer 150, the array layer 150 is disposed between the substrate 140 and the touch layer 101, the light-emitting unit is disposed on the side of the array layer 150 facing away from the substrate 140, and the touch layer 101 may be located on the side of the light-emitting unit facing away from the substrate 140.

[0083] In some embodiments, a plurality of driving units are disposed in the array layer 150, the plurality of driving units may be arranged in an array, the driving units are electrically connected to the light-emitting units, and the driving units are configured to supply driving currents to the light-emitting units. The driving unit may include a Thin Film Transistor (abbreviated as TFT) and a capacitor.

[0084] In some embodiments, refer to Figure 7 , the array layer 150 ( Figure 1 ) includes a second structure 152, the orthogonal projection of the second structure 152 on the substrate 140 overlaps with the orthogonal projection of the fracture 121 on the substrate 140, and both the second structure 152 and the touch layer 101 are metal members. In this way, when light irradiates the fracture 121, the light can pass through the fracture 121 to irradiate the second structure 152, which reduces the reflection difference between the portion of the touch layer 101 without the fracture 121 and the portion with the fracture 121, can weaken the "mouth"-shaped bright spots of the display panel 100 under strong light irradiation, thereby improving the display effect of the display panel 100.

[0085] In some embodiments, refer to Figure 7 , a second insulating layer 162 is disposed between the array layer 150 and the touch layer 101.

[0086] In some embodiments, the array layer 150 includes a plurality of metal layers, a first insulating layer is disposed between two adjacent metal layers, and the second structure 152 is located in at least one metal layer.

[0087] In some embodiments, the array layer 150 includes a transistor, the plurality of metal layers includes a first metal layer, and the gate of the transistor is located in the first metal layer. For example, the second structure 152 may be located in the first metal layer.

[0088] In some embodiments, the array layer 150 includes a capacitor, the plurality of metal layers includes a second metal layer, and one electrode plate of the capacitor is located in the second metal layer. For example, the second structure 152 may be located in the second metal layer.

[0089] In some embodiments, the array layer 150 includes transistors, and the multilayer metal layer includes a third metal layer, with the first and second terminals of the transistors located on the third metal layer. Exemplarily, the second structure 152 may be located on the third metal layer. Here, one of the first and second terminals is the source of the transistor, and the other is the drain of the transistor.

[0090] In some embodiments, see Figure 2 The touch electrode block 110 is configured as a self-capacitive touch electrode block, and the self-capacitive touch electrode block and ground form a self-capacitance.

[0091] In other embodiments, see Figure 3 The touch layer 101 includes a connector 132. Touch electrode blocks 110 are configured as mutually capacitive touch electrode blocks. The touch layer 101 may include multiple first touch electrodes 101a and multiple second touch electrodes 102a, which intersect and form a mutual capacitive capacitance. Each of the first and second touch electrodes 101a includes multiple touch electrode blocks 110, and adjacent touch electrode blocks 110 of the first touch electrode 101a are connected by the connector 132. The display panel 100 may include a bonding member 163, which is disposed on a different layer from the touch layer 101. Adjacent touch electrode blocks 110 of the second touch electrode 102a are connected by the bonding member 163. The bonding member 163 may be located on the side of the light-emitting unit facing away from the substrate 140.

[0092] For example, one of the first touch electrode 101a and the second touch electrode 102a is a driving electrode, and the other of the first touch electrode 101a and the second touch electrode 102a is a sensing electrode (detection electrode).

[0093] It should be noted that, Figure 2 and Figure 3 The grid pattern of the touch electrode blocks is not shown; instead, a rough graphic of the outer contour of the touch electrode blocks is shown.

[0094] See Figure 1 and Figure 4The display panel 100 may have a first direction X, a second direction Y, and a third direction Z, all of which are different. The first direction X and the second direction Y can be any two different directions parallel to the display panel 100, and the third direction Z can be any direction intersecting the display panel 100. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. For example, the first direction X can be the length direction of the display panel 100, the second direction Y can be the width direction of the display panel 100, and the third direction Z can be the thickness direction of the display panel 100. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length. The orientation of the display panel 100 can be consistent with the orientation of the film layers such as the substrate 140.

[0095] In some embodiments, there are multiple break groups 120 between two adjacent touch electrode blocks 110. There are at least three break groups 120 between two adjacent touch electrode blocks 110. For example, the number of break groups 120 between two adjacent touch electrode blocks 110 can be any number of 3, 4, 5, or more than 5.

[0096] In some embodiments, between two adjacent touch electrode blocks 110 along the first direction X, a plurality of break groups 120 are arranged at equal intervals along the first direction X, and the distance between each adjacent break group 120 along the first direction X is equal. Thus, in the manufacturing process of the display panel 100, the equally spaced break groups 120 are easier to standardize the manufacturing process, and the production of equally spaced break groups 120 is relatively simple. This can reduce the number of process adjustments during the manufacturing process and improve production efficiency.

[0097] In other embodiments, the distance between some adjacent break groups 120 along the first direction X between two adjacent touch electrode blocks 110 is not equal to the distance between some adjacent break groups 120 along the first direction X. Thus, between two adjacent touch electrode blocks 110 along the first direction X, multiple break groups 120 are arranged at unequal intervals along the first direction X. The unequally spaced break groups 120 can better disperse stress, so that the stress can be more evenly distributed on the entire panel.

[0098] In some embodiments, between two adjacent touch electrode blocks 110 along the second direction Y, a plurality of break groups 120 are arranged at equal intervals along the second direction Y. Thus, during the manufacturing process of the display panel 100, the equally spaced break groups 120 are easier to standardize the manufacturing process, and the production of equally spaced break groups 120 is relatively simple. This can reduce the number of process adjustments during the manufacturing process and improve production efficiency.

[0099] In other embodiments, between two adjacent touch electrode blocks 110 along the second direction Y, the distance of some adjacent fracture groups 120 along the second direction Y is not equal to the distance of other adjacent fracture groups 120 along the second direction Y. In this way, between the two adjacent touch electrode blocks 110 along the second direction Y, the plurality of fracture groups 120 are arranged at unequal intervals along the second direction Y. The unequally spaced fracture groups 120 can better disperse stress, so that the stress can be more evenly distributed on the entire panel.

[0100] In some embodiments, refer to Figure 2 , the outer peripheral sidewall of the touch electrode block 110 includes a first outer peripheral wall 111 and a second outer peripheral wall 112 disposed opposite to each other along the first direction X. The line jointly fitted by the center lines of the plurality of fractures 121 of the first fracture group 120a at the first outer peripheral wall 111 is a broken line or a curve. In this way, the plurality of fractures 121 in the first fracture group 120a at the first outer peripheral wall 111 are arranged along the broken line or the curve, so that the distance between two adjacent fractures 121 in the first fracture group 120a at the first outer peripheral wall 111 is relatively long, the plurality of fractures 121 in the first fracture group 120a at the first outer peripheral wall 111 are arranged relatively dispersedly, the observability of the plurality of fractures 121 in the first fracture group 120a at the first outer peripheral wall 111 is reduced, the square-shaped bright spots of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100.

[0101] In some embodiments, the line jointly fitted by the center lines of the plurality of fractures 121 of the first fracture group 120a at the second outer peripheral wall 112 is a broken line or a curve. In this way, the observability of the plurality of fractures 121 in the first fracture group 120a at the second outer peripheral wall 112 is reduced, the square-shaped bright spots of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100, and the principle thereof has been elaborated and will not be repeated.

[0102] In some embodiments, refer to Figure 2 , the outer peripheral sidewall of the touch electrode block 110 includes a third outer peripheral wall 113 and a fourth outer peripheral wall 114 disposed opposite to each other along the second direction Y. The line jointly fitted by the center lines of the plurality of fractures 121 of the first fracture group 120a at the third outer peripheral wall 113 is a broken line or a curve. In this way, the observability of the plurality of fractures 121 in the first fracture group 120a at the third outer peripheral wall 113 is reduced, the square-shaped bright spots of the display panel 100 under strong light irradiation can be weakened, thereby improving the display effect of the display panel 100, and the principle thereof has been elaborated and will not be repeated.

[0103] In some embodiments, the line jointly fitted by the centerlines of the plurality of fractures 121 of the first fracture group 120a at the fourth outer peripheral wall 114 is a broken line or a curve. In this way, the observability of the plurality of fractures 121 in the first fracture group 120a at the fourth outer peripheral wall 114 is reduced, which can weaken the "mouth"-shaped bright spot of the display panel 100 under strong light irradiation, thereby improving the display effect of the display panel 100. The principle thereof has been described and will not be repeated here.

[0104] In some embodiments, refer to Figure 5 , two adjacent touch electrode blocks 110 are defined as a first touch electrode block 110a and a second touch electrode block 110b respectively. Among the two touch electrode blocks 110 adjacent along the first direction X, in the first fracture group 120a, the first side wall 1211 is close to the first touch electrode block 110a, and the second side wall 1212 is close to the second touch electrode block 110b. The first line S1 of the first fracture group 120a at the outer peripheral side wall of the first touch electrode block 110a on the side close to the second touch electrode block 110b is parallel to the second line S2 of the first fracture group 120a at the outer peripheral side wall of the second touch electrode block 110b on the side close to the first touch electrode block 110a. In this way, the shapes of the first line S1 and the second line S2 are adapted to each other, which is beneficial to reducing the distance between the two touch electrode blocks 110 adjacent along the first direction X, and is beneficial to increasing the arrangement density of the touch electrode blocks 110.

[0105] In some embodiments, among the two touch electrode blocks 110 adjacent along the second direction Y, the first line S1 of the first fracture group 120a at the outer peripheral side wall of the first touch electrode block 110a on the side close to the second touch electrode block 110b is parallel to the second line S2 of the first fracture group 120a at the outer peripheral side wall of the second touch electrode block 110b on the side close to the first touch electrode block 110a. In this way, the shapes of the first line S1 and the second line S2 are adapted to each other, which is beneficial to reducing the distance between the two touch electrode blocks 110 adjacent along the second direction Y, and is beneficial to increasing the arrangement density of the touch electrode blocks 110.

[0106] In some embodiments, refer to Figure 5 , in the first fracture group 120a between the touch electrode block 110 and the first structure 131 that are adjacent along the first direction X, the first line S1 and the second line S2 of the first fracture group 120a are parallel. In this way, the shapes of the first line S1 and the second line S2 are adapted to each other, which is beneficial to reducing the distance between the touch electrode block 110 and the first structure 131 adjacent along the first direction X, and is beneficial to increasing the wiring density of the touch layer 101.

[0107] In some embodiments, in the first break group 120a between the adjacent touch electrode blocks 110 and the first structure 131 along the second direction Y, the first line S1 and the second line S2 of the first break group 120a are parallel. In this way, the shapes of the first line S1 and the second line S2 are adapted to each other, which is beneficial to reducing the distance between the adjacent touch electrode blocks 110 and the first structure 131 along the second direction Y, and to improving the wiring density of the touch layer 101.

[0108] For example, the material of at least one of the touch layer 101 and the second structure may include metals such as titanium, silver, copper, aluminum, and molybdenum, or alloys, or conductive oxides (such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), aluminum zinc oxide (AZO), zinc gallium oxide, titanium tantalum oxide, tin oxide, cadmium oxide, and indium oxide, or any one or more of these.

[0109] The following describes the light-emitting unit provided in the embodiments of this application.

[0110] In some embodiments, multiple light-emitting units are spaced apart along a direction perpendicular to the thickness of the substrate 140. For example, the multiple light-emitting units may be arranged in an array.

[0111] For example, the multiple light-emitting units include, but are not limited to, red light-emitting units, green light-emitting units, and blue light-emitting units. In other examples, the multiple light-emitting units may also include white light-emitting units.

[0112] In some embodiments, the light-emitting unit may include a first electrode, a light-emitting material, and a second electrode sequentially stacked along a direction away from the substrate 140. One of the first electrode and the second electrode may be an anode, and the other of the first electrode and the second electrode may be a cathode.

[0113] For example, the light-emitting unit may also include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole block layer (HBL), and an electron block layer (EBL).

[0114] When using the terms “including,” “having,” and “comprising” as described herein, another component may be added unless explicitly qualifying terms such as “only,” “consisting of,” etc. are used. Unless otherwise stated, singular terms may include plural forms and should not be construed as having a quantity of one.

[0115] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
