[0063] As shown in Figure 1 and Figure 2 embodiments of the first aspect of the present application provide a display panel 10, comprising a substrate 100, an isolation structure 200 and a shielding layer 300. The isolation structure 200 is arranged on the substrate 100, and the isolation structure 200 encloses to form an isolation opening 210 and a light transmission opening 220, the isolation opening 210 is used to accommodate a light emitting unit 500; the shielding layer 300 is arranged on the substrate 100, and the shielding layer 300 comprises a shielding part 310, and the shielding part 310 is arranged at least partially overlapped with the light transmission opening 220 in the projection of the substrate 100.

However, forming the light transmission opening 220 on the isolation structure 200 will cause the parasitic capacitance to be easily generated between the conductive layers 400 located on the upper and lower sides of the isolation structure 200 at the position of the light transmission opening 220.

[0066] In these optional embodiments, the projection of the second signal line 421 on the substrate 100 is at least partially staggered with the projection of the light transmission opening 220 on the substrate 100, thereby improving the influence of the second signal line 421 on the light transmission rate.

[0067] Optionally, the conductive layer 400 further comprises a first sub-conductive layer 410 located on the side of the shielding layer 300 facing the substrate 100, the first sub-conductive layer 410 comprises a first signal line 411, and the first signal line 411 is arranged at least partially overlapped with the second signal line 421 in the orthographic projection of the substrate 100. The parasitic capacitance between the first signal line 411 and the second signal line 421 is prone to be generated, and the shielding part 310 can shield and improve the parasitic capacitance between the first signal line 411 and the second signal line 421.

[0068] Optionally, the first signal line 411 is arranged in a misaligned manner with the light-transmitting opening 220 in the orthographic projection of the substrate 100, so as to improve the influence of the first signal line 411 on the light transmittance.

[0069] The first signal line 411 can be arranged in various modes, and the first signal line 411 can comprise at least one of a data line, a scan line, and a voltage reference line. The second signal line 421 can comprise one of a touch wire and the like. As long as the first signal line 411 and the second signal line 421 can transmit current and meet the above-mentioned positional relationship, the first signal line 411 and the second signal line 421 can be arranged in various modes.

[0070] The substrate 100 can be arranged in various modes, and the substrate 100 can comprise a substrate 110, a first conductive layer, a second conductive layer, and a third conductive layer arranged on one side of the substrate 110 in a stacked manner. Insulating layers are arranged between adjacent conductive layers. For example, the pixel driving circuit arranged on the array substrate comprises a transistor and a storage capacitor.

For example, the gate and the first plate can be located on the first conductive layer, the second plate can be located on the second conductive layer, and the source and the drain can be located on the third conductive layer.

[0073] In these optional embodiments, the first sub-layer 201 is located within the projection of the second sub-layer 202 on the substrate 100, so that a concave is formed on the side of the second sub-layer 202 facing the substrate 100. When the light-emitting material is evaporated, the light-emitting material can be broken near the isolation structure 200 to form independent light-emitting units 500, thereby omitting the close mask evaporation process and simplifying the preparation process of the display panel 10.

[0074] Optionally, the display panel 10 further comprises a second electrode layer 600, the second electrode layer 600 comprises a second electrode 610 located on the side of each light-emitting unit 500 away from the substrate 100.

By arranging the third sub-layer 203, when the first sub-layer 201 is side-etched so that the projection of the first sub-layer 201 on the substrate 100 is located within the projection of the second sub-layer 202 on the substrate 100, the material under the third sub-layer 203 can be protected, and damage to the layer structure under the third sub-layer 203 can be avoided. Optionally, the material of the third sub-layer 203 comprises a conductive material, and the second electrode 610 is also electrically connected to the third sub-layer 203, so as to increase the contact area between the second electrode 610 and the isolation structure 200 and reduce the overall resistance of the second electrode 610.

[0076] The shielding layer 300 can be arranged on the side of the first electrode layer 120 facing the substrate 110, or the shielding layer 300 can be arranged on the side of the first electrode layer 120 away from the substrate 110.

[0077] Optionally, the shielding layer 300 is arranged on the side of the first electrode layer 120 facing the substrate 110. The number of shielding portions 310 can be multiple. At least one of the multiple shielding portions 310 can be connected to the first electrode 121, so that the first electrode 121 can be connected to the pixel driving circuit through the shielding portion 310. The shielding portion 310 not only has a shielding effect on the first signal line 411 and the second signal line 421, but also can be used to connect the first electrode 121 and the pixel driving circuit, which can enrich the function of the shielding portion 310 and simplify the structure of the display panel 10.

[0079] Optionally, a planarization layer 130 is arranged between the substrate 110 and the first electrode layer 120, and the shielding layer 300 is arranged on the side of the planarization layer 130 facing the substrate 100. The planarization layer 130 is arranged between the shielding portion 310 and the first electrode layer 120, which can improve the short-circuit connection problem between the shielding portion 310 and the first electrode 121.

[0080] As described above, when the substrate 100 includes the first conductive layer 400, the second conductive layer 400, and the third conductive layer 400, the shielding layer 300 is arranged on the side of the third conductive layer 400 away from the substrate 110.

[0081] In other optional embodiments, as shown in Figure 1 and Figure 3 The substrate 100 further includes a power signal line 700. At least one shielding portion 310 and the power signal line 700 are electrically connected to each other. The shielding portion 310 can be used to transmit a power signal, which can increase the distribution area of the power signal line 700 and reduce the resistance of the power signal line 700. The power signal line 700 is, for example, a driving power voltage signal line. For example, the power signal line 700 is used to provide a positive voltage. The power signal line 700 is connected to the first electrode 121 through the pixel driving circuit to drive the first electrode 121.

[0082] Optionally, the power signal line 700 is arranged in a position different from the orthographic projection of the light-transmitting opening on the substrate 110, so as to improve the influence of the power signal line 700 on the light transmittance.

[0083] Optionally, the shielding portion 310 and the power signal line 700 are in the same layer and are in contact with each other. The shielding portion 310 can carry a stable voltage signal, which can improve the problem of parasitic capacitance.

[0084] The power signal line 700 can be at least one of a driving power voltage signal line, a voltage reference line, a ground signal line, and a low-level power voltage signal line. For example, the power signal line 700 can be a driving power voltage signal line, so that the power signal line 700 can have a more stable potential. The power signal line 700 having a stable potential means that the voltage of the power signal line 700 is stable within a frame display period. The driving power voltage signal line can be a VSS signal line or a VDD signal line.

[0085] Optionally, the at least two power signal lines 700 are distributed at intervals, and the shielding part 310 is connected between the adjacent two power signal lines 700, so as to further increase the distribution area of the shielding part 310 and reduce the resistance of the power signal line 700.

[0086] Optionally, the shielding part 310 can be located between the adjacent two power signal lines 700 connected by the shielding part 310. Alternatively, in other embodiments, the shielding part 310 and at least one of the orthogonal projection of the substrate 100 and the adjacent two power signal lines 700 connected by the shielding part 310 are arranged to overlap the orthogonal projection part of the substrate 100, so as to increase the contact area of the shielding part 310 and the power signal line 700.

[0087] In other embodiments, as shown in Figure 1 and Figure 4 , the shielding part 310 is located on the side of the power signal line 700 away from the substrate 110, and the shielding part 310 and the power signal line 700 are connected by a via. In these embodiments, the shielding part 310 and the power signal line 700 are directly connected by a via, which can improve the stability of the connection between the shielding part 310 and the power signal line 700, and thus enable the shielding part 310 to provide a stable shielding effect.

[0088] Optionally, as shown in Figure 4 , at least part of the power signal line 700 is located in the orthogonal projection of the shielding part 310 on the substrate 110. On the one hand, this can reduce the distance between the power signal line 700 and the shielding part 310, and the power signal line 700 and the shielding part 310 can be connected by punching in the thickness direction of the display panel; on the other hand, this can increase the size of the shielding part 310 and improve the shielding effect of the shielding part 310.

[0089] Optionally, as described above, the power signal line 700 can be a driving power voltage signal line, and the substrate 100 includes a bridge line 320 connecting the first electrode 121 and the power signal line 700, and the shielding part 310 and the bridge line 320 are arranged in the same layer. For example, the shielding part 310 is located in the fourth conductive layer, so that the bridge line 320 and the shielding part 310 can be prepared at the same process step, which can simplify the preparation process of the display panel.

[0090] Optionally, the shielding portion 310 and the bridge line 320 are insulated from each other. Alternatively, in other embodiments, the shielding portion 310 and the bridge line 320 can also be connected to each other.

Figure 1 Figure 5 In some other optional embodiments, as shown in FIG. 3B, the shielding layer 300 is disposed on the side of the isolation structure 200 facing the substrate 100, the shielding portion 310 and the isolation structure 200 are at least partially overlapped in the orthographic projection of the substrate 100, and the shielding portion 310 and the isolation structure 200 are electrically connected to each other.

[0092] In these optional embodiments, the shielding layer 300 is disposed on the side of the isolation structure 200 facing the substrate 100 and overlaps the orthographic projection of the isolation structure 200 on the substrate 100, so that the shielding portion 310 and the isolation structure 200 are electrically connected to each other, which can reduce the overall resistance of the first electrode 121.

[0093] Optionally, the shielding layer 300 and the isolation structure 200 are disposed adjacent to each other in the thickness direction, and the shielding portion 310 and the isolation structure 200 are directly connected to each other, which can increase the contact area between the shielding portion 310 and the isolation structure 200.

[0094] As described above, when the isolation structure 200 includes the first sub-layer 201 and the second sub-layer 202, the shielding portion 310 can be electrically connected to the first sub-layer 201, and the shielding portion 310 can be located on the side of the first sub-layer 201 facing the substrate 100. For example, the shielding portion 310 is located on the side of the first sub-layer 201 facing the substrate 100 and is in contact with the first sub-layer 201.

[0095] When the isolation structure 200 further includes the third sub-layer 203 located on the side of the first sub-layer 201 facing the substrate 100, the shielding portion 310 can be electrically connected to the third sub-layer 203, for example, the shielding portion 310 is located on the side of the third sub-layer 203 facing the substrate 100 and is in contact with the first sub-layer 201.

[0096] Optionally, the display panel 10 further includes an insulating layer 140, and the insulating layer 140 is disposed on the substrate 100. The insulating layer 140 has a pixel opening 141, and the orthographic projection of the pixel opening 141 on the substrate 100 is located within the orthographic projection of the isolation opening 210 on the substrate 100. The pixel opening 141 is used to accommodate the light emitting unit 500. By disposing the insulating layer 140, the short circuit connection between the isolation structure 200 and the first electrode 121 can be improved.

[0097] Optionally, when the display panel 10 further includes the insulating layer 140, and the insulating layer 140 includes the pixel opening 141, the pixel opening 141 is located within the isolation opening 210, and the light emitting unit 500 within the isolation opening 210 is located within the pixel opening 141.​

[0098] Optionally, each first electrode 121 is exposed through the pixel opening 141 so that the first electrode 121 can interact with the second electrode 610 to make the light-emitting unit 500 emit light for display.

[0099] There are several ways to set the insulating layer 140, for example, such as Figure 6 As shown, the insulating layer 140 only surrounds each of the first electrodes 121. Each first electrode 121 has an effective area and an edge area surrounding the effective area. The insulating layer 140 includes multiple insulating portions, each covering the edge area of ​​each first electrode 121, allowing the effective area to be exposed through the pixel opening 141. The effective area determines the light-emitting area, and the edge area is covered by the insulating layer 140 to improve the short-circuit connection between the isolation structure 200 and the first electrode 121. That is, in these optional embodiments, the insulating layer 140 has a clearance opening 142, through which at least a portion of the substrate 100 is exposed, and the isolation structure 200 is disposed on the substrate 100 exposed by the clearance opening 142. The clearance opening 142 is formed between adjacent insulating portions, allowing the isolation structure 200 to be disposed on the substrate 100 through the gap between adjacent insulating portions.

[0100] In some alternative embodiments, the insulating layer 140 is a pixel definition layer, and the isolation structure 200 is disposed on the side of the pixel definition layer facing away from the substrate 100. The isolation structure 200 being disposed on the side of the pixel definition layer facing away from the substrate 100 means that the isolation structure 200 and the first electrode 121 are completely separate layers, which can better improve the short-circuit connection between the isolation structure 200 and the first electrode 121.

[0101] There are various material options for the shielding part 310. For example, the material of the shielding part 310 includes at least one of indium tin oxide and indium zinc oxide, so that the shielding part 310 not only has good transmittance, but also good conductivity.

[0102] In some alternative embodiments, the orthographic projection of the light-transmitting opening 220 onto the substrate 100 lies within the orthographic projection of the shielding portion 310 onto the substrate 100. This allows the light-transmitting opening 220 to be completely blocked by the shielding portion 310, thus better mitigating the problem of parasitic capacitance.

[0103] In some optional embodiments, there are multiple light-transmitting openings 220, and these openings are spaced apart. Each light-transmitting opening 220 is provided with a corresponding shielding portion 310. The provision that each light-transmitting opening 220 is provided with a corresponding shielding portion 310 means that the orthographic projection of each light-transmitting opening 220 on the substrate 100 at least partially overlaps with the orthographic projection of at least one shielding portion 310 on the substrate 100. By providing multiple light-transmitting openings 220, the light transmittance of the display panel 10 can be improved.

[0104] Optionally, the number of the light emitting units 500 is multiple, the multiple light emitting units 500 are distributed in rows and columns along the first direction X and the second direction Y, the light transmission opening 220 is located between two adjacent rows of the light emitting units 500, the first direction X is a row direction, the second direction Y is a column direction, and the same light transmission opening 220 overlaps with two or more light emitting units 500 in the column direction. That is, one light transmission opening 220 is provided corresponding to multiple light emitting units 500, which can increase the distribution area of the light transmission opening 220 and further improve the light transmittance of the display panel 10.

[0106] Optionally, as described above, when the substrate 100 comprises a substrate 110 and a first electrode layer 120, the shielding layer 300 can be arranged on the side of the first electrode layer 120 facing the substrate 110, or the shielding layer 300 can be arranged on the side of the first electrode layer 120 away from the substrate 110. Alternatively, the shielding layer 300 can be arranged in the same layer as the first electrode layer 120.

[0107] The arrangement mode of the substrate 100, the isolation structure 200 and the shielding layer 300 is as described above in the embodiment of the display panel 10, and will not be described here again.
