The touch trace 420 is rewired to the connecting part 220 in the non-display area NA. The connecting part 220 is arranged closer to the substrate 100. More insulating layers are arranged on the connecting part 220. The connecting part 220 is not easy to be damaged. The risk of damage of the touch trace 420 can be improved, and the use performance of the display panel can be improved.
[0085] In addition, the touch signal is usually electrically connected to the touch electrode 410 through a signal line in the substrate 100, for signal transmission. The connecting part 220 is closer to the substrate 100 than the touch trace 420. The connection between the connecting part 220 and the signal line in the substrate 100 is more stable. Compared with the connection between the touch trace 420 and the signal line in the substrate 100, the touch trace 420 is first connected to the connecting part 220 which is closer, and then the connecting part 220 is connected to the signal line which is closer.

The isolation structure 200 can separate the light-emitting material into independent light-emitting units 300, so as to form the light-emitting unit 300 located in each isolation opening 211.
[0088] Optionally, the touch electrode 410 can be a mutual-capacitance touch electrode, and the touch electrode 410 includes a touch driving electrode and a touch sensing electrode, and the touch function is realized through the interaction of the touch driving electrode and the touch sensing electrode. Optionally, the touch wire 420 includes a first wire part and a second wire part, the first wire part is connected to the touch driving electrode, and the second wire part is connected to the touch sensing electrode.

Optionally, the touch driving electrode and the touch sensing electrode are arranged in the same layer, one of the touch driving electrode and the touch sensing electrode is connected to each other in the same layer, and the other is connected to each other through a bridge electrode, and the bridge electrode is arranged in a layer different from the conductive layer in which the touch driving electrode and the touch sensing electrode are arranged. That is, the touch function layer 400 includes two conductive layers, one of which is used to arrange the touch electrode 410, and the other of which is used to arrange the bridge electrode. The touch wire 420 can be arranged in the same layer as the touch electrode 410 or the bridge electrode.

A plurality of touch electrodes 410 are arranged in the same layer, and a bridge electrode arranged in a different layer is not required to connect adjacent touch electrodes 410.

Optionally, when the touch electrode 410 is a self-capacitance touch electrode, the touch wire 420 is arranged in the same layer as the touch electrode 410, and the touch wire 420 can be changed through the connecting part 220.
[0090] In some optional embodiments, the display panel further includes an optical adjustment layer 500, and the optical adjustment layer 500 is arranged on a side of the touch function layer 400 away from the substrate 100.

The touch wire 420 is located on a side of the giving-up slot 511 facing the display area AA, that is, the touch wire 420 and the giving-up slot 511 do not overlap, which can improve the structure of the film layer on the touch wire 420 affected by the opening of the giving-up slot 511, and improve the yield of the touch wire 420.
[0093] Optionally, when the touch electrode 410 is a self-capacitance touch electrode, the touch function layer 400 includes a conductive layer for setting the touch electrode 410 and the touch trace 420, the conductive layer is close to the optical adjustment layer 500, for example, the conductive layer is in contact with the optical adjustment layer 500. The connecting part 220 is arranged away from the optical adjustment layer 500 relative to the touch trace 420, and the touch trace 420 is changed by the connecting part 220, so that the touch signal is transmitted through the film layer away from the optical adjustment layer 500, and the accommodation groove 511 arranged in the optical adjustment layer 500 is not easy to affect the yield of the connecting part 220.

In addition, the connecting part 220 and the isolation part 210 can be prepared and formed in the same process step, so as to simplify the preparation process of the display panel.
[0095] In some optional embodiments, the accommodation groove 511 is located in the adjustment layer farthest from the substrate 100 among the two or more adjustment layers, that is, the accommodation groove 511 is located in the adjustment layer farthest from the substrate 100 among the optical adjustment layer 500.
[0096] Specifically, the two or more adjustment layers include: a first adjustment layer 510 located on the side of the touch function layer 400 away from the substrate 100; and a second adjustment layer 520 arranged on the side of the first adjustment layer 510 away from the substrate 100, wherein the accommodation groove 511 is arranged in the first adjustment layer 510.
[0097] In the alternative embodiments, the two or more adjustment layers include a first adjustment layer 510 and a second adjustment layer 520, and the second adjustment layer 520 is located on a side of the first adjustment layer 510 away from the substrate 100. The relief groove 511 is arranged on the first adjustment layer 510 close to the touch function layer 400, so as to avoid the problem that the relief groove 511 affects the touch trace 420. By changing the touch trace 420 to the connection part 220, the influence of the relief groove 511 on the touch trace 420 can be improved, and the user can also set the shape of the relief groove 511 according to the use requirement. The relief groove 511 is arranged to accommodate the second adjustment layer 520, so as to improve the overflow problem of the second adjustment layer 520, so that the second adjustment layer 520 can be cut off at the relief groove 511, thereby reducing the display panel defects.
[0098] In the alternative embodiments, the second adjustment layer 520 is prepared by an inkjet printing process, and the relief groove 511 can better improve the overflow problem of the second adjustment layer 520.
[0099] Optionally, the refractive index of the second adjustment layer 520 is greater than the refractive index of the first adjustment layer 510.
