[0077] It should be noted that, without conflict, different features in the embodiments of the present application can be combined with each other.

[0078] Please refer to Figure 1 , Figure 1 which is a display panel provided in this embodiment. The display panel may include an array substrate 110, a first electrode layer, an isolation structure 141, and a touch control electrode 142. The related technical solutions of the isolation structure and the touch control electrode are described in patent applications PCT / CN2023 / 134518, 202310759370.2, 202310740412.8, 202310707209.0, 202311346196.5, 202311395816.4, the content of which is incorporated into this application by reference for reference.

[0079] The array substrate 110 may include a plurality of film layer structures, such as a substrate, a buffer layer, an active layer, a plurality of metal layers, a plurality of insulating layers, and a planarization layer, etc. The plurality of film layer structures of the array substrate 110 may form a plurality of thin film transistors (TFTs) at different positions of the array substrate 110, and the thin film transistors may cooperate with each other to form a plurality of driving units, and the driving units are used to drive the pixels to emit light.

[0080] The first electrode layer is located on one side of the array substrate 110, and the first electrode layer includes a plurality of first electrodes 120. Each first electrode 120 may be electrically connected to one or more driving units in the array substrate 110 to obtain electrical energy from the driving units. The plurality of first electrodes 120 may be arranged at intervals.

[0081] The isolation structure 141 and the touch control electrode 142 are located on the same side of the array substrate 110 as the first electrode layer. There is a gap between the isolation structure 141 and the touch control electrode 142, and the isolation structure 141 includes a plurality of first openings exposing the first electrodes 120. Optionally, please refer to Figure 1 and Figure 2 , Figure 2 which is a schematic diagram of the isolation structure 141 provided in this embodiment, and the isolation structure 141 may be provided on the same layer as the touch control electrode 142.

[0082] Please refer to Figures 1 to 4 , Figure 3 which is a schematic diagram of the first electrode layer provided in this embodiment, Figure 4 is a perspective view of the isolation structure 141, the touch control electrode 142, and the first electrode layer, Figure 1 is Figure 4 a cross-sectional schematic diagram of the position A-A shown. Among them, at least a part of the orthographic projection of at least one touch control electrode 142 on the array substrate 110 coincides with at least a part of the orthographic projection of at least one first electrode 120 on the array substrate 110.

[0083] Based on the above design, at the overlapping position of the first electrode 120 and the touch electrode 142, the first electrode 120 can act as a shielding layer to isolate the influence of the touch electrode 142 on other traces in the array substrate 110, thereby reducing the interference of the touch electrode 142 on the display signal in the array substrate 110.

[0084] In some possible implementation manners, the display panel may further include a pixel defining layer 130. The pixel defining layer 130 is located on a side of the first electrode layer away from the array substrate 110. The pixel defining layer 130 includes a second opening exposing the first electrode 120. Adjacent first electrodes 120 are isolated from each other through the pixel defining layer 130. The isolation structure 141 and the touch electrode 142 are located on a side of the pixel defining layer 130 away from the array substrate 110. The orthographic projections of the isolation structure 141 and the touch electrode 142 on the array substrate 110 are within the orthographic projection of the pixel defining layer 130 on the array substrate 110. The second opening of the pixel defining layer 130 communicates with the first opening of the isolation structure 141 to form a pixel opening.

[0085] In some possible implementation manners, the touch electrode 142 may adopt a self-capacitance layout manner, that is, an electrode block composed of one touch electrode 142 or a plurality of adjacent touch electrodes 142 can be relatively independently connected to a touch detection circuit through traces. For example, please refer to Figure 5 , Figure 5 For Figure 4 the cross-sectional schematic view at the B-B position shown in

[0086] In a possible implementation manner, the display panel includes at least one pixel unit. Please refer to Figure 6 , Figure 6 For Figures 2 to 4Schematic diagram of a pixel unit 200 shown by the dashed box in the middle, where the touch electrode 142 includes a target touch electrode 1421 corresponding to the pixel unit. The pixel unit includes adjacent first sub-pixel 201 and second sub-pixel 202. The first sub-pixel 201 and the second sub-pixel 202 share a first electrode 120 as a common electrode 121. At least a part of the target touch electrode 1421 is located between the isolation structure 141 corresponding to the first sub-pixel 201 and the isolation structure 141 corresponding to the second sub-pixel 202, and the orthographic projection of the target touch electrode 1421 on the array substrate 110 coincides at least partially with the orthographic projection of the common electrode 121 on the array substrate 110.

[0087] For example, in terms of the film layer where the isolation structure 141 is located, there may be a first gap between the isolation structures 141 corresponding to the first sub-pixel 201 and the second sub-pixel 202 of the pixel unit, and at least a part of the target touch electrode 1421 corresponding to the pixel unit may be located in this first gap. In terms of the first electrode layer, the first sub-pixel 201 and the second sub-pixel 202 of the pixel unit can share a first electrode 120 as a common electrode 121. When the common electrode 121 is driven by the pixel driving circuit in the array substrate 110, the first sub-pixel 201 and the second sub-pixel 202 can emit light simultaneously.

[0088] In this case, the orthographic projection of the part of the target touch electrode 1421 located in the first gap on the array substrate 110 coincides at least partially with the orthographic projection of the common electrode 121 on the array substrate 110. The common electrode 121 can shield this part of the touch electrode 142.

[0089] Furthermore, please refer to again Figure 6 , in some possible implementation manners, the pixel unit further includes a third sub-pixel 203 and a fourth sub-pixel 204. The first sub-pixel 201, the second sub-pixel 202, the third sub-pixel 203, and the fourth sub-pixel 204 are arranged in an array, and the first sub-pixel 201 and the second sub-pixel 202 are in the same column in the first direction D1, and the third sub-pixel 203 and the fourth sub-pixel 204 are in the same column in the first direction D1. The first sub-pixel 201 can be in the same row in the second direction D2 as one of the third sub-pixel 203 and the fourth sub-pixel 204, and the second sub-pixel 202 can be in the same row in the second direction D2 as the other of the third sub-pixel 203 and the fourth sub-pixel 204. Wherein, the second direction D2 intersects with the first direction D1. For example, the second direction D2 can be perpendicular to the first direction D1.

[0090] Regarding the film layer where the isolation structure 141 is located, there is a first gap between the isolation structure 141 corresponding to the first sub-pixel 201 and the isolation structure 141 corresponding to the second sub-pixel 202, and there is a second gap between the isolation structure 141 corresponding to the third sub-pixel 203 and the isolation structure 141 corresponding to the fourth sub-pixel 204. The target touch electrode 1421 extends in the first gap and the second gap along the second direction D2.

[0091] Regarding the first electrode layer, the first sub-pixel 201 and the second sub-pixel 202 can share a first electrode 120 as a common electrode 121, while the third sub-pixel 203 and the fourth sub-pixel 204 can respectively have different first electrodes 120 as first independent electrodes 122.

[0092] Regarding the relationship between the target touch electrode 1421 and the first electrode layer, a part of the projection of the target touch electrode 1421 on the array substrate 110 is located between the projections of the first electrode 120 of the third sub-pixel 203 (i.e., the first independent electrode 122 of the third sub-pixel 203) and the first electrode 120 of the fourth sub-pixel 204 (i.e., the first independent electrode 122 of the fourth sub-pixel 204) on the array substrate 110; another part of the projection of the target touch electrode 1421 on the array substrate 110 coincides with the projection of the common electrode 121 on the array substrate 110.

[0093] It should be noted that the display panel provided in this embodiment may also have other pixel units in addition to the above pixel units. For example, the pixel units in the light-transmitting display area where an under-screen camera needs to be set may not have corresponding touch electrodes 142. There may be relatively large light-transmitting gaps between the isolation structures 141 of different sub-pixels, and the isolation structures 141 can be electrically connected through a light-transmitting conductive layer. Or, touch electrodes 142 may not be provided at other positions where touch detection does not need to be implemented, which will not be elaborated here one by one.

[0094] On this basis, in a possible implementation manner, the first sub-pixel 201 and the second sub-pixel 202 are sub-pixels that emit the first color light, the third sub-pixel 203 is a sub-pixel that emits the second color light, and the fourth sub-pixel 204 is a sub-pixel that emits the third color light; the first color light, the second color light, and the third color light are different. For example, the first color light is blue light, the second color light is red light, and the third color light is green light.

[0095] Adopting the above pixel layout can make the white light center when the three-color sub-pixels emit light in a pixel unit located at the center of the pixel unit, thereby ensuring that color deviation is not likely to occur at the boundary position of the display panel.

[0096] It should be noted that in this embodiment, the first color light, the second color light, and the third color light can also have other different combinations. For example, in other implementation manners of this embodiment, the first color light can also be green light, and the second color light and the third color light are red light and blue light respectively.

[0097] In some possible implementation manners, the accuracy of touch detection is lower than that of display. Therefore, a plurality of adjacent touch electrodes 142 can be connected to each other to form a touch electrode block, and the touch electrode block as a whole is connected to a touch detection chip as a touch detection point.

[0098] For example, at least some adjacent touch electrodes 142 can be electrically connected to each other through a first connection trace 301 to form a touch electrode block, and the first connection trace 301 is located in the first electrode layer and / or the array substrate 110. Optionally, in the first direction D1, the target touch electrodes 1421 corresponding to at least two adjacent pixel units are electrically connected to each other through the first connection trace 301.

[0099] Specifically, in a possible implementation manner, please refer to Figure 7 , in the second direction D2, the target touch electrodes 1421 corresponding to at least two adjacent pixel units 200 (as shown by the rectangular dotted line frame in Figure 7 ) are spaced apart from each other (as shown by the elliptical dotted line frame in Figure 7 ).

[0100] Please refer to Figure 8 , in the first direction D1, the target touch electrodes 1421 corresponding to at least two adjacent pixel units are electrically connected to each other through the first connection trace 301. In the second direction D2, the target touch electrodes 1421 corresponding to two adjacent pixel units can be electrically connected to each other through a second connection trace 302, and the second connection trace 302 is located in the first electrode layer and / or the array substrate 110.

[0101] Thus, please refer to Figure 9 , Figure 9 is a schematic diagram of the connection relationship of the target touch electrode 1421, the first connection trace 301, and the second connection trace 302 in the above solution. Among them, a plurality of adjacent target touch electrodes 1421 can be connected into a conductive integral structure through the first connection trace 301 and the second connection trace 302 as a touch electrode block.

[0102] It should be noted that, please refer to Figure 7 again. In the above solution, the isolation structures 141 of a plurality of adjacent pixel units can be directly connected to each other. Therefore, it is not necessary to set additional connection traces in other film layers to connect the respective isolation structures 141, thereby reducing the wiring difficulty of other film layers.

[0103] In another possible implementation, please refer to Figure 10 , in the second direction D2, the target touch electrodes 1421 corresponding to at least two adjacent pixel units (as shown by the rectangular dashed box in Figure 10 ) extend along the second direction D2 until they are interconnected. In this way, the target touch electrodes 1421 corresponding to two adjacent pixel units can be connected in the second direction D2 to form an electrode strip (as shown by the elliptical dashed box in Figure 7 ).

[0104] In the first direction D1, the target touch electrodes 1421 corresponding to at least two adjacent pixel units are electrically connected to each other through the first connection trace 301.

[0105] Please refer to Figure 11 , Figure 11 , which is a schematic diagram of the connection relationship between the target touch electrode 1421 and the first connection trace 301 in the above solution. Among them, multiple adjacent target touch electrodes 1421 can be connected into a conductive integral structure only through the first connection trace 301 as a touch electrode block. In this way, compared with the connection solution shown in Figure 9 , the connection solution shown in Figure 11 requires fewer connection traces provided on the first electrode layer and / or the array substrate 110, which is more conducive to the routing layout of the first electrode layer and / or the array substrate 110, and thus more conducive to improving the pixel density.

[0106] Optionally, please refer to Figure 10 again. In the second direction D2, the target touch electrode 1421 disconnects the isolation structures 141 on both sides of it. Therefore, please refer to Figure 12 . On the basis of the above solution, the isolation structures 141 on both sides of the target touch electrode 1421 in the second direction D2 can be electrically connected through the third connection trace 303, and the third connection trace 303 is located on the first electrode layer and / or the array substrate 110. In this way, the overall connectivity rate of the isolation structure 141 can be higher, thereby reducing the power supply voltage drop (IR drop) when the isolation structure 141 transmits the common voltage VSS as a whole.

[0107] It should be noted that in this embodiment, Figure 9 and Figure 11 only show two possible connection methods of the connection traces and the touch electrode 142. In other implementation manners of this embodiment, on the premise of ensuring that multiple adjacent target touch electrodes 1421 can be connected into a touch electrode block, the number of the first connection trace 301 and / or the second connection trace 302 can also be reduced, as shown in Figure 13 and Figure 14 .

[0108] Further, in one example, please refer back to Figure 7 or Figure 10 , the width of the first part of the target touch electrode 1421 located in the first gap may be the same as the width of the second part of the target touch electrode 1421 located in the second gap.

[0109] In another example, please refer to Figure 15 or Figure 16 , in the first direction D1, the width W1 of the first part of the target touch electrode 1421 located in the first gap is less than the width W2 of the second part of the target touch electrode 1421 located in the second gap. Thus, by adjusting the width W2 of the second part of the target touch electrode 1421 located in the second gap, the opening areas of the third sub-pixel 203 and the fourth sub-pixel 204 can be adjusted, so that the opening areas of each sub-pixel are more adapted to the attenuation rates of different color light-emitting materials, ensuring the long-term display color uniformity of the display panel.

[0110] In some other possible implementation manners, please refer to Figure 17 and Figure 18 , different from the solution shown in Figure 6 , in the solutions shown in Figure 17 and Figure 18 , the first sub-pixel 201 may also have an independent first electrode 120 as a second independent electrode 124, and the second sub-pixel 202 may also have an independent first electrode 120 as a third independent electrode 125. Among them, at least one of the second independent electrode 124 and the third independent electrode 125 may at least partially overlap with the positive projection of the target touch electrode 142 on the array substrate.

[0111] On this basis, the first sub-pixel 201 and the second sub-pixel 202 may be sub-pixels that emit the same color light (for example, both the first sub-pixel 201 and the second sub-pixel 202 are blue-light-emitting sub-pixels). For example, the second independent electrode 124 and the third independent electrode 125 are driven by the same pixel driving circuit; the first sub-pixel 201 and the second sub-pixel 202 may be sub-pixels that emit different color lights. For example, the second independent electrode 124 and the third independent electrode 125 are driven by different pixel driving circuits.

[0112] In some possible implementation manners, the isolation structure 141 includes a second support portion and a second shielding portion that are stacked in a direction away from the array substrate 110, and the positive projection of the second support portion on the array substrate 110 is located within the positive projection of the second shielding portion on the array substrate 110.

For example, the material of the first metal layer may be molybdenum, the material of the second metal layer may be aluminum, and the material of the third metal layer may be titanium.

[0114] In some possible implementation manners, please refer to Figure 1 again, and the display panel may further include a light-emitting layer and a second electrode layer.

[0115] The light-emitting layer is located on a side of the first electrode layer away from the array substrate 110. The light-emitting layer includes a plurality of light-emitting units 150, and the light-emitting units 150 are located in the second opening and in contact with the first electrode 120.

[0116] The second electrode layer is located on a side of the light-emitting layer away from the array substrate 110. The second electrode layer includes a plurality of second electrodes 160. At least a part of the second electrodes 160 is located in the second opening and in contact with the light-emitting units 150, and the second electrodes 160 extend from the second opening to be in electrical contact with the isolation structure 141.

[0117] Wherein, the light-emitting units 150 are located between the first electrode 120 and the second electrode 160. When there is a potential difference between the first electrode 120 and the second electrode 160, the light-emitting units 150 are driven to emit light.

[0118] In some possible implementation manners, please refer to Figure 1 again, and the display panel may further include a first encapsulation layer on a side of the second electrode 160 away from the array substrate 110.

[0119] The first encapsulation layer includes a plurality of first encapsulation units 170. At least a part of the first encapsulation units 170 is located in the second opening, and the first encapsulation units 170 extend from the second opening to a side of the isolation structure 141 away from the array substrate 110.

[0120] Optionally, the first encapsulation units 170 corresponding to adjacent sub-pixels are disconnected from each other on a side of the isolation structure 141 away from the array substrate 110.

[0121] Wherein, in the case of having the isolation structure 141, the light-emitting units 150, the second electrodes 160, and the first encapsulation units 170 can be formed in different pixel openings by means of etching after whole-layer evaporation.

[0122] Optionally, the isolation structure 141 includes a second support portion and a second shielding portion stacked in a direction away from the array substrate 110, and a positive projection of the second support portion on the array substrate 110 is located within a positive projection of the second shielding portion on the array substrate 110.

[0123] Optionally, the second support portion includes a first metal layer and a second metal layer stacked in a direction away from the array substrate 110, and the second shielding portion includes a third metal layer. For example, the material of the first metal layer may be molybdenum, the material of the second metal layer may be aluminum, and the material of the third metal layer may be titanium.

[0124] Optionally, the second electrode layer may extend from within the second opening to make electrical contact with the first metal layer.

[0125] In some possible implementation manners, please refer again to Figure 1 , the display panel further includes a second encapsulation layer 180 and a third encapsulation layer 190.

[0126] The second encapsulation layer 180 is located on a side of the first encapsulation layer away from the array substrate 110, and the third encapsulation layer 190 is located on a side of the second encapsulation layer 180 away from the array substrate 110.

[0127] Optionally, the materials of the first encapsulation layer and the third encapsulation layer 190 include inorganic materials, and the material of the second encapsulation layer 180 includes organic materials. For example, the first encapsulation layer and the third encapsulation layer 190 may be formed by chemical vapor deposition, and the second encapsulation layer 180 may be formed by inkjet printing.
