[0065] In the display panel provided in the embodiment of the present application, the display panel includes a substrate 100, an isolation structure 300 and a functional layer 400. The isolation structure 300 includes an isolation portion 301 and a light-emitting area 302 located between at least part of the adjacent isolation portions 301. The light-emitting unit 230 is arranged in the light-emitting area 302 to realize the light-emitting display of the display panel. The functional layer 400 includes a first electrode 410 and a touch electrode 420. The first electrode 410 is located in the light-emitting area 302 and is arranged on the light-emitting unit 230 to drive the light-emitting unit 230 to emit light. The touch electrode 420 is arranged on the side of the isolation portion 301 away from the substrate 100, so that the isolation structure 300 can isolate the touch electrode 420 and the first electrode 410 from each other, and the first electrode 410 and the touch electrode 420 are not easily short-circuited. The present application can divide the functional layer 400 into the first electrode 410 and the touch electrode 420, and the structure of the display panel is simplified without the need to separately set up a touch structure layer, and the touch effect can be guaranteed.

[0066] Optionally, the touch electrode 420 includes a plurality of sub-electrodes 4201 arranged at intervals, and the plurality of sub-electrodes 4201 are connected to each other via a connecting portion 4202 .

[0067] In these optional embodiments, the touch electrode 420 is divided into a plurality of sub-electrodes 4201, and there is a gap between adjacent sub-electrodes 4201 to arrange the first electrode 410, so that the first electrode 410 is distributed more evenly, and the distribution area of ​​a single sub-electrode 4201 can be reduced, thereby reducing the voltage drop of the sub-electrode 4201 and improving the touch effect.

[0068] At least some of the adjacent isolation parts 301 are spaced apart and enclose the light-emitting region 302. Two adjacent isolation parts 301 are spaced apart, and the light-emitting region 302 is formed between the two adjacent isolation parts 301. Alternatively, the isolation part 301 is irregularly shaped, and two parts of the isolation part 301 itself are spaced apart, and the light-emitting region 302 is formed between the two parts spaced apart in the isolation part 301 itself.

[0069] Optionally, the distribution pattern of the touch electrode 420 matches the distribution pattern of the isolation structure 300. The purpose of the isolation structure 300 is to support the touch electrode 420 so that the touch electrode 420 and the first electrode 410 are insulated from each other. Therefore, the isolation structure 300 is provided in the area where the touch electrode 420 is provided, and the isolation structure 300 is located on the side of the touch electrode 420 facing the substrate 100 to support the touch electrode 420.

[0070] Optionally, at least some of the touch electrodes 420 are provided with gaps, and correspondingly, at least some of the isolation parts 301 used to support the touch electrodes 420 are provided with gaps, and the gaps are the light-emitting areas 302. At least some of the first electrodes 410 are located in the gaps (i.e., the light-emitting areas 302) and are electrically connected to each other through the gaps. Optionally, at least some of the sub-electrodes 4201 are provided with gaps, and correspondingly, at least some of the isolation parts 301 used to support the sub-electrodes 4201 are provided with gaps, and at least some of the first electrodes 410 are located in the gaps and are electrically connected to each other through the gaps.

[0071] In the embodiment of the present application, by adding the isolation structure 300, not only can the functional layer 400 be divided into the first electrode 410 and the touch electrode 420, but also by setting a gap between the isolation parts 301 (i.e., the light-emitting area 302), it can also be ensured that the first electrodes 410 can be interconnected to form a whole-surface electrode. On the basis of simplifying the display panel structure, the problem that the touch electrode 420 and the first electrode 410 are arranged in the same layer, which affects the interconnection of the first electrode 410 into a whole-surface electrode, is also solved.

[0072] Optional, such as Figure 1 and Figure 2As shown, the display panel includes a display area AA, and the first electrodes 410 can be interconnected to form a whole-surface electrode.

Optionally, the display panel may further include a non-display area arranged around the display area AA.

[0073] In the embodiment of the present application, the touch electrode 420 is divided into multiple sub-electrodes 4201 , and there are gaps between adjacent sub-electrodes 4201 . At least part of the first electrode 410 is located between adjacent sub-electrodes 4201 . This can reduce the distribution area of ​​a single sub-electrode 4201 and reduce the voltage drop of the touch electrode 420 .

[0074] Optionally, the touch electrode 420 and the isolation part 301 are arranged in a one-to-one correspondence.

The plurality of sub-isolation parts are interconnected by the bridge isolation part, and the plurality of sub-isolation parts are arranged at intervals from each other, so that the sub-electrodes 4201 located on the side of the sub-isolation part away from the substrate 100 can be arranged at intervals from each other, and the bridge isolation part is used to connect the plurality of sub-isolation parts, so that the connection part 4202 located on the side of the bridge isolation part away from the substrate 100 can connect the plurality of sub-electrodes 4201.

The second direction Y intersects with the first direction X, for example, the first direction X and the second direction Y are perpendicular. The second sub-portion 410b being located on the side of the sub-electrode 4201 away from the connecting portion 4202 means that the second sub-portion 410b is located on the side of the sub-electrode 4201 away from the connecting portion 4202 in the same touch electrode 420.
