[0062] Figure 1 is a schematic structural diagram of a display panel 10 provided in an embodiment of the present application; Figure 2 In one example Figure 1 Cross-sectional view at AA in the middle.

[0063] like Figure 1 and Figure 2 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 and a conductive shielding layer 300. The isolation structure 200 is disposed on the substrate 100, and the isolation structure 200 encloses an isolation opening 210 and a light-transmitting opening 220, and the isolation opening 210 is used to accommodate the light-emitting unit 500; the conductive shielding layer 300 is disposed on the substrate 100, and the conductive shielding layer 300 includes a conductive shielding portion 310, and the orthographic projection of the conductive shielding portion 310 on the substrate 100 and the orthographic projection of the light-transmitting opening 220 on the substrate 100 are at least partially overlapped.

[0064] In the display panel 10 provided in the embodiment of the present application, the display panel 10 includes a substrate 100, an isolation structure 200 and a conductive shielding layer 300. The isolation structure 200 is used to form an isolation opening 210 so that the light-emitting unit 500 can be arranged in the isolation opening 210. The isolation structure 200 is also used to form a light-transmitting opening 220 to improve the light-transmitting performance of the display panel 10. However, forming the light-transmitting opening 220 on the isolation structure 200 will cause parasitic capacitance to be easily generated at the position of the light-transmitting opening 220 between the conductive layers 400 located on the upper and lower sides of the isolation structure 200. The present application sets a conductive shielding portion 310, and makes the orthographic projection of the conductive shielding portion 310 on the substrate 100 and the orthographic projection of the light-transmitting opening 220 on the substrate 100 at least partially overlap, so that the conductive shielding portion 310 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.

[0065] In some optional embodiments, the display panel 10 also includes a conductive layer 400, the conductive layer 400 includes a second sub-conductive layer 420 located on the side of the isolation structure 200 away from the substrate 100, the second sub-conductive layer 420 includes a second signal line 421, and the orthographic projection of the second signal line 421 on the substrate 100 and the orthographic projection of the light-transmitting opening 220 on the substrate 100 are staggered.

[0066] In these optional embodiments, the orthographic projection of the second signal line 421 on the substrate 100 and the orthographic projection of the light-transmitting opening 220 on the substrate 100 are at least partially misaligned, thereby improving the influence of the second signal line 421 on the transmittance.

[0067] Optionally, the conductive layer 400 further includes a first sub-conductive layer 410 located on the side of the conductive shielding layer 300 facing the substrate 100, and the first sub-conductive layer 410 includes a first signal line 411, and the orthographic projection of the first signal line 411 on the substrate 100 and the orthographic projection of the second signal line 421 on the substrate 100 are at least partially overlapped. This makes it easy to generate parasitic capacitance between the first signal line 411 and the second signal line 421, and by providing the conductive shielding portion 310, the conductive shielding portion 310 can play a shielding role, thereby improving the parasitic capacitance between the first signal line 411 and the second signal line 421.

[0068] Optionally, the orthographic projection of the first signal line 411 on the substrate 100 and the orthographic projection of the light-transmitting opening 220 on the substrate 100 are staggered to improve the influence of the first signal line 411 on the transmittance.

[0069] There are many ways to set the first signal line 411. The first signal line 411 may include at least one of a data line, a scan line, and a voltage reference line. The second signal line 421 may include one of the signal lines such as a touch line. As long as the first signal line 411 and the second signal line 421 can transmit current and meet the above positional relationship, it will be fine.

[0070] There are many ways to set the substrate 100. The substrate 100 may include a substrate 110 and a first conductive layer, a second conductive layer, and a third conductive layer that are arranged on one side of the substrate 110 and are stacked. An insulating layer is provided between adjacent conductive layers. Exemplarily, the pixel driving circuit provided on the array substrate 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. As an example, the gate and the first plate may be located in the first conductive layer, the second plate may be located in the second conductive layer, and the source and the drain may be located in the third conductive layer.

[0071] Optionally, the substrate 100 also includes a first electrode layer 120 arranged on the substrate 110. The first electrode layer 120 may include a first electrode 121 corresponding to each isolation opening 210. The first electrode 121 is arranged corresponding to each light-emitting unit 500. The first electrode 121 is located on the side of each light-emitting unit 500 facing the substrate 110.

[0072] There are many ways to set the isolation structure 200.

[0073] In these optional embodiments, the orthographic projection of the first sublayer 201 on the substrate 100 is located within the orthographic projection of the second sublayer 202 on the substrate 100, so that a concave is formed on the side of the second sublayer 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 tight mask evaporation process and simplifying the preparation process of the display panel 10.

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

Optionally, the material of the first sublayer 201 includes a conductive material, and the second electrode 610 and the first sublayer 201 are electrically connected to each other. Optionally, the material of the second sublayer 202 may also include a conductive material to increase the distribution area of ​​the conductive part in the isolation structure 200 and reduce the overall resistance of the second electrode 610.

[0075] Optionally, the isolation structure 200 may further include a third sublayer 203 located on the side of the first sublayer 201 facing the substrate 100, and the orthographic projection of the first sublayer 201 on the substrate 100 is located within the orthographic projection of the third sublayer 203 on the substrate 100. By providing the third sublayer 203, when the first sublayer 201 is side-engraved so that the orthographic projection of the first sublayer 201 on the substrate 100 is located within the orthographic projection of the second sublayer 202 on the substrate 100, the material under the third sublayer 203 can be protected to avoid damage to the layer structure under the third sublayer 203. Optionally, the material of the third sublayer 203 includes a conductive material, and the second electrode 610 is also electrically connected to the third sublayer 203 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] There are many settings for the conductive shielding layer 300. As mentioned above, when the display panel 10 includes a first electrode layer 120, the conductive shielding layer 300 can be set on the side of the first electrode layer 120 facing the substrate 110, or the conductive shielding layer 300 can be set on the side of the first electrode layer 120 facing away from the substrate 110.

[0077] Optionally, the conductive shielding layer 300 is disposed on the side of the first electrode layer 120 facing the substrate 110, and there may be multiple conductive shielding portions 310, and at least one of the multiple conductive shielding portions 310 may be connected to the first electrode 121, so that the first electrode 121 may be connected to the pixel driving circuit through the conductive shielding portion 310. The conductive shielding portion 310 may not only shield the first signal line 411 and the second signal line 421, but also be used to connect the first electrode 121 and the pixel driving circuit, thereby enriching the role of the conductive shielding portion 310 and simplifying the structure of the display panel 10.

[0078] Optionally, each conductive shielding portion 310 is connected to each first electrode 121 , so that the structure and shape of each conductive shielding portion 310 tend to be consistent, further simplifying the structure of the display panel 10 .

[0079] Optionally, a planarization layer 130 is disposed between the substrate 110 and the first electrode layer 120, and the conductive shielding layer 300 is disposed on the side of the planarization layer 130 facing the substrate 100. The planarization layer 130 is disposed between the conductive shielding portion 310 and the first electrode layer 120, which can improve the short circuit connection problem between the conductive 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 conductive shielding layer 300 is disposed on a side of the third conductive layer 400 facing away from the substrate 110 .

The conductive 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, and 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 orthographic projection of the power signal line 700 on the substrate 110 and the orthographic projection of the light-transmitting opening on the substrate are staggered to improve the influence of the power signal line 700 on the transmittance.

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

[0084] The power signal line 700 may 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 may be a driving power voltage signal line, so that the power signal line 700 may have a more stable potential. The power signal line 700 having a stable potential means that its voltage is stable within a frame display period. The driving power voltage signal line may be a VSS signal line or a VDD signal line.

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

[0086] Optionally, the conductive shielding portion 310 may be located between two adjacent power signal lines 700 connected thereto. Alternatively, in other embodiments, the orthographic projection of the conductive shielding portion 310 on the substrate 100 and the orthographic projection of at least one of the two adjacent power signal lines 700 connected thereto on the substrate 100 are overlapped to increase the contact area between the conductive shielding portion 310 and the power signal line 700.

In these embodiments, the conductive shielding portion 310 and the power signal line 700 are directly connected through a via hole, which can improve the stability of the connection between the conductive shielding portion 310 and the power signal line 700, thereby enabling the conductive shielding portion 310 to provide a stable shielding effect.

[0088] Optional, please continue to Figure 4 , at least part of the orthographic projection of the power signal line 700 on the substrate 110 is located within the orthographic projection of the conductive shielding portion 310 on the substrate 110. On the one hand, the distance between the power signal line 700 and the conductive shielding portion 310 can be reduced, and the power signal line 700 and the conductive shielding portion 310 can be connected by drilling along the thickness direction of the display panel; on the other hand, the size of the conductive shielding portion 310 can be increased, and the shielding effect of the conductive shielding portion 310 can be improved.

[0089] Optionally, as described above, the power signal line 700 may 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 conductive shielding portion 310 and the bridge line 320 are arranged in the same layer. The conductive shielding portion 310 is, for example, located in the fourth conductive layer, so that the bridge line 320 and the conductive shielding portion 310 can be prepared simultaneously in the same process step, which can simplify the preparation process of the display panel.

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

The insulating layer 140 includes a plurality of insulating parts, each of which covers the edge area of ​​each first electrode 121, and the effective area is exposed by the pixel opening 141.

For example, the material of the conductive shielding portion 310 includes at least one of indium tin oxide and indium zinc oxide, so that the conductive shielding portion 310 has not only good transmittance but also good conductivity.

[0102] In some optional embodiments, the orthographic projection of the light-transmitting opening 220 on the substrate 100 is located within the orthographic projection of the conductive shielding portion 310 on the substrate 100.
