[0055] In order to better understand the present application, the display panel and the display device of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0056] Please refer to Figures 1 to 3 , Figure 1is a schematic diagram of a top view structure of a display panel provided in an embodiment of the present application; Figure 2 In one example Figure 1 A schematic diagram of the enlarged structure of position B in the middle; Figure 3 In one example Figure 2 The cross-sectional view at AA in FIG. Wherein, position B is within the display area AA of the display panel 10. Wherein, Figure 2 It is a schematic diagram of the enlarged structure after hiding the conductive layer.

[0057] like Figures 1 to 3 As shown, an embodiment of the first aspect of the present application provides a display panel 10, including a substrate 100, an isolation structure 200, a light-emitting unit 300, a first electrode 400 and a second electrode 600, wherein a plurality of second electrodes 600 are arranged at intervals on the substrate 100. The isolation structure 200 is arranged on the same side of the substrate 100 as the second electrode 600, and the isolation structure 200 encloses an isolation opening 210 and a first opening 220, the second electrode 600 is exposed from the isolation opening 210, and the orthographic projection of the second electrode 600 on the substrate 100 is staggered from the orthographic projection of the first opening 220 on the substrate 100. The light-emitting unit 300 includes a first light-emitting unit 310 and a second light-emitting unit 320, the first light-emitting unit 310 is located in the isolation opening 210 and on the side of the second electrode 600 facing away from the substrate 100, and the second light-emitting unit 320 is located in the first opening 220. The first electrode 400 includes a first sub-electrode 410 and a second sub-electrode 420. The first sub-electrode 410 is located in the isolation opening 210. The first sub-electrode 410 is located on the side of the first light-emitting unit 310 facing away from the substrate 100. At least a portion of the first sub-electrode 410 overlaps with the inner wall surface of the isolation structure 200 facing the isolation opening 210. The second sub-electrode 420 is located in the first opening 220. The second sub-electrode 420 is not located on the side of the second light-emitting unit 320 facing away from the substrate 100. At least a portion of the second sub-electrode 420 overlaps with the inner wall surface of the isolation structure 200 facing the first opening 220.

[0058] Optionally, when the display panel 10 is in use, the first light-emitting unit 310 is powered on and emits light, and the second light-emitting unit 320 does not emit light, that is, the first opening 220 can be used as a light-transmitting opening. The first opening 220 as a light-transmitting opening can improve the transmittance of the display panel 10. The increase in transmittance helps implement the under-screen camera solution and improve the imaging effect of the under-screen camera. In addition, the first opening 220 can also be used to accommodate fingerprint routing, thereby reducing the overall thickness of the display panel 10.

[0059] Optionally, the isolation structure 200 is used to isolate the light-emitting unit 300 and the first electrode 400. The second light-emitting unit 320 can be evaporated synchronously with the first light-emitting unit 310, and the second sub-electrode 420 can be evaporated synchronously with the first sub-electrode 410. During evaporation, due to the isolation effect of the isolation structure 200, the evaporated material will fall into different openings respectively to form the light-emitting units 300 arranged at intervals or the first electrodes 400 arranged at intervals. Among them, the materials of the first sub-electrode 410 and the second sub-electrode 420 are the same. Optionally, the second electrode 600 and the first sub-electrode 410 are both electrically connected to the first light-emitting unit 310 to supply power to the first light-emitting unit 310. Specifically, one of the second electrode 600 and the first sub-electrode 410 is an anode and the other is a cathode. The embodiment of the present application is illustrated by taking the second electrode 600 as an anode and the first sub-electrode 410 as a cathode. In the present application, the second electrode 600 is not provided on the side of the second light-emitting unit 320 facing the substrate 100, so that only the first light-emitting unit 310 can be powered on and emit light. The second light-emitting unit 320 in the first opening 220 has no anode power supply and does not emit light, and the second sub-electrode 420 in the first opening 220 is used as a shielding layer.

[0060] In the display panel 10 provided in the embodiment of the present application, by using the isolation structure 200 to separate the light-emitting unit 300 and the first electrode 400, no mask is required when evaporating the light-emitting unit 300 and the first electrode 400, thereby saving the mask mold opening fee and manufacturing cost. By arranging the second sub-electrode 420 in the first opening 220, the second sub-electrode 420 can play the role of a shielding layer, thereby improving the parasitic capacitance generated in the display panel 10 and improving the performance of the display panel 10. By evaporating the second light-emitting unit 320 and the first light-emitting unit 310 simultaneously, the second sub-electrode 420 and the first sub-electrode 410 are simultaneously evaporated, and the second light-emitting unit 320 and the second sub-electrode 420 do not need to add additional steps to prepare, thereby reducing the preparation process and reducing the production cost of the display panel 10.

[0061] In some optional embodiments, a conductive layer 500 is further included, the conductive layer 500 includes a first sub-conductive layer 510 arranged on the substrate 100 and a second sub-conductive layer 520 located on the side of the isolation structure 200 away from the substrate 100, the first sub-conductive layer 510 includes a first signal line 511, the second sub-conductive layer 520 includes a second signal line 521, and the first signal line 511 and the second signal line 521 are located on different sides of the first sub-electrode 410.

[0062] Optionally, the orthographic projection of the first opening 220 on the substrate 100 is at least partially outside the orthographic projection of the first signal line 511 on the substrate 100 , and the orthographic projection of the first opening 220 on the substrate 100 is at least partially outside the orthographic projection of the second signal line 521 on the substrate 100 .

[0063] Even if the first signal line 511 and the second signal line 521 are not necessarily directly opposite to the first opening 220, when no shielding layer is provided on the first opening 220, parasitic capacitance will still be generated between the first signal line 511 and the second signal line 521 through the first opening 220. When the first signal line 511 and the second signal line 521 overlap, the parasitic capacitance between the first signal line 511 and the second signal line 521 is the largest. However, even if the first signal line 511 and the second signal line 521 are staggered, when no shielding layer is provided on the first opening 220, parasitic capacitance will still be generated between the first signal line 511 and the second signal line 521 through the first opening 220. In the present application, by preparing the second sub-electrode 420 in the first opening 220, the second sub-electrode 420 made of metal material can act as a shielding layer, thereby improving the parasitic capacitance generated in the display panel 10 and improving the performance of the display panel 10.

[0064] Optionally, the orthographic projection of the isolation opening 210 on the substrate 100 is at least partially located outside the orthographic projection of the second signal line 521 on the substrate 100 .

[0065] Optionally, the first signal line 511 includes at least one of a data line, a scan line, a power signal line, and a voltage reference line. There are many ways to set the substrate 100. The substrate 100 may include a substrate and a first conductive layer, a second conductive layer, and a third conductive layer that are arranged on one side of the substrate and stacked, and an insulating layer is arranged between adjacent conductive layers. One of the first conductive layer, the second conductive layer, and the third conductive layer can be arranged in the same layer as the first sub-conductive layer 510. Exemplarily, the pixel driving circuit arranged on the substrate 100 includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate, a source and a drain. The storage capacitor includes a first plate and a second plate.
