[0066] Figure 1 This is a schematic diagram of a top view structure of a display panel provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the cross-sectional structure of a display panel provided in an embodiment of the present application.

[0067] In order to better understand this application, Figures 1 to 13 The display panel and the display device according to the embodiments of the present application are described in detail.

[0068] In view of this, first of all, please refer to Figure 1 and Figure 2 An embodiment of the present application provides a display panel having a display area AA and a non-display area NA. For example, the non-display area NA surrounds at least a portion of the display area AA.

[0069] The display panel includes a first conductive layer and a first functional layer 70. The first conductive layer includes a first connection line 80 located in the non-display area NA and at least a portion of the isolation structure 60 located in the display area AA.

At least a portion of the second connection line 73 is located in the non-display area NA.

[0070] The display panel has a display area AA and a non-display area NA. The display area AA is used to display images. Peripheral wiring, functional components, or other structures can be arranged in the non-display area NA to increase the integration of the display panel. The non-display area NA can be arranged around the entire display area AA. Alternatively, the non-display area NA can be arranged around a portion of the display area AA. Optionally, the non-display area NA can also be arranged within the display area AA.

[0071] The first conductive layer includes at least a portion of the isolation structure 60 and a first connection line 80. At least a portion of the isolation structure 60 and the first connection line 80 are disposed in the same layer, and the first connection line 80 and the isolation structure 60 are insulated from each other. Optionally, the first connection line 80 can be disposed around the display area AA. Of course, the first connection line 80 can be located on at least one side of the display area AA, such as at least one of the top, bottom, left, or right borders.

[0072] The first functional layer 70 includes a first functional electrode 71, a second functional electrode 72, and a second connecting line 73. The functions that the first functional electrode 71 and the second functional electrode 72 can perform can be the same, or of course, different. The first functional electrode 71 and the second functional electrode 72 can be touch electrodes, such as self-capacitive touch electrodes or mutual-capacitive touch electrodes. For example, the first functional electrode 71 and the second functional electrode 72 can be touch drive electrodes, or the first functional electrode 71 and the second functional electrode 72 can be touch sensing electrodes, or one of the first functional electrode 71 and the second functional electrode 72 can be a touch drive electrode and the other a touch sensing electrode. The first functional layer may include a touch functional layer.

[0073] Optionally, the first functional electrode 71 and the second functional electrode 72 may be stacked or arranged in different layers. Alternatively, the first functional electrode 71 and the second functional electrode 72 may be located in the same layer but in different regions.

[0074] In some embodiments, the first functional electrode 71 is electrically connected to the first connecting wire 80, and the second functional electrode 72 is electrically connected to the second connecting wire 73. In other embodiments, the first functional electrode 71 is electrically connected to the second connecting wire 73, and the second functional electrode 72 is electrically connected to the first connecting wire 80. The first connecting wire 80 and the second connecting wire 73 are insulated and not electrically connected.

[0075] Optionally, the display panel may include a substrate 10, with a first conductive layer and a first functional layer 70 stacked on the substrate 10 along a thickness direction Z of the substrate, wherein an orthographic projection of the first conductive layer on the substrate 10 and an orthographic projection of the first functional layer 70 on the substrate 10 at least partially overlap. Of course, the orthographic projection of the first conductive layer on the substrate 10 and the orthographic projection of the first functional layer 70 on the substrate 10 are spaced apart.

[0076] In the display panel provided in an embodiment of the present application, the display panel includes a display area AA and a non-display area NA. The display panel includes a first functional electrode 71 and a second functional electrode 72. At least a portion of the isolation structure 60 and the first connecting line 80 are located in the first conductive layer to reduce the manufacturing process of the first connecting line 80. The second connecting line 73, the first functional electrode 71, and the second functional electrode 72 are all located in the first functional layer 70 to reduce the manufacturing process of the second connecting line 73. The connecting line of the first functional electrode 71 and the connecting line of the second functional electrode 72 are the first connecting line 80 and the second connecting line 73, respectively. The first connecting line 80 and the second connecting line 73 transmit different signals. Compared to the solution of arranging the first connecting line 80 in the first functional layer, by arranging the first connecting line 80 and the second connecting line 73 in different conductive layers, the distance between the first connecting line 80 and the second connecting line 73 is increased, and / or the thickness and / or number of layers of the insulating layer between the first connecting line 80 and the second connecting line 73 are increased, thereby reducing the possibility of interference between the two different signals, thereby improving the performance of the display panel.

[0077] In some embodiments, as Figure 2 As shown, the first functional electrode 71 is a touch electrode 711, and the second functional electrode 72 is a pressure sensing electrode 721; and / or, the display panel also includes a substrate 10, and the first functional layer 70 is located on the side of the first conductive layer away from the substrate 10; and / or, the display panel also includes an encapsulation layer 90, and the encapsulation layer 90 is located between the first conductive layer and the first functional layer 70; and / or, the film layer where the first functional electrode 71 is located is located on the side of the film layer where the second functional electrode 72 is located away from the first conductive layer; the first functional electrode 71 is electrically connected to the second connecting line 73; the second functional electrode 72 is electrically connected to the first connecting line 80; and / or, one of the first functional electrode 71 and the second functional electrode 72 is arranged on the same layer as the second connecting line 73.

[0078] The “and / or” here means that the content before and after “and / or” can be set in the same embodiment or in different embodiments.

[0079] In some embodiments, one of the first functional electrode 71 and the second functional electrode 72 is a touch electrode, and the other is a pressure sensing electrode. Alternatively, the first functional electrode 71 is a pressure sensing electrode, and the second functional electrode 72 is a touch electrode. Alternatively, the first functional electrode 71 is a touch electrode 711, and the second functional electrode 72 is a pressure sensing electrode 721.

[0080] The touch electrodes 711 may include first and second touch electrodes that are insulated from each other. The first touch electrodes may include a plurality of first touch electrode blocks 711a arranged along a first direction Y and electrically connected in sequence. The second touch electrodes may include a plurality of second touch electrode blocks 711b arranged along a second direction X and electrically connected in sequence. Touch capacitance is formed between the first touch electrode blocks 711a and the second touch electrode blocks 711b. To implement the touch function, a user can touch the touch area of ​​the display panel with a finger or other device. The charge carried by the finger or other device can cause the touch capacitance at the touch point to change, thereby implementing the touch function.

[0081] The pressure sensing electrode 721 can form a pressure sensing capacitor. The deformation caused by a finger or other device at the touch point can change the pressure sensing capacitor, thereby realizing a touch function or other functions, such as a weighing function or an atmospheric pressure detection function. In these optional embodiments, by setting the first functional electrode 71 and the second functional electrode 72 as electrodes with different functions, the functions of the display panel are increased, thereby achieving functional diversification of the display panel.

[0082] The touch electrodes 711 and the pressure sensing electrodes 721 may both be located in the display area AA, so that the touch area includes the display area AA, allowing the user to interact with the display screen through touch.

[0083] Optionally, the first functional layer 70 is located on a side of the first conductive layer facing away from the substrate 10 . Optionally, the first functional layer 70 may be a touch functional layer, and the first functional layer 70 may implement a touch function.

[0084] Optionally, the display panel further includes an encapsulation layer 90, which is located between the first conductive layer and the first functional layer 70. The encapsulation layer 90 may be an insulating layer. Optionally, the encapsulation layer 90 may include a multi-layer structure, and the number of film layers included in the encapsulation layer 90 between the first conductive layer and the first functional layer 70 in the display area AA may be the same as or different from the number of film layers included in the encapsulation layer 90 between the first conductive layer and the first functional layer 70 in the non-display area NA. In these optional embodiments, by providing the encapsulation layer 90, the distance between the first conductive layer and the first functional layer 70 is increased, thereby increasing the distance between the first connection line 80 and the second connection line 73, thereby reducing the interference between the signal in the first connection line 80 and the signal in the second connection line 73.

[0085] The film layer containing the first functional electrode 71 is located on the side of the film layer containing the second functional electrode 72 that is farther from the first conductive layer. That is, the first and second functional electrodes 71, 72 are located in different film layers. In the thickness direction Z of the display panel, the second functional electrode 72 is located between the first functional electrode 71 and the first conductive layer. The first functional electrode 71 is electrically connected to the second connecting wire 73, while the second functional electrode 72 is electrically connected to the first connecting wire 80. The first functional electrode 71 can transmit signals via the second connecting wire 73, and the second functional electrode 72 can transmit signals via the first connecting wire 80.

[0086] In some examples, the first functional electrode 71 and the second connecting line 73 are disposed in the same layer. The film layer containing the first functional electrode 71 is located on the side of the film layer containing the second functional electrode 72 that is farther away from the first conductive layer. Therefore, the distance between the second connecting line 73 and the first connecting line 80 can be further increased to reduce signal interference between the second connecting line 73 and the first connecting line 80. The first functional electrode 71 and the second connecting line 73 are electrically connected and disposed in the same layer to reduce the number of vias. For example, the first functional electrode 71 and the second connecting line 73 do not require a via to connect them. In other embodiments, the first functional electrode 71 and the second connecting line 73 can also be disposed in different layers.

[0087] In other examples, the second functional electrode 72 and the second connecting line 73 are provided in the same layer. The film layer where the second functional electrode 72 is located is located on the side of the film layer where the first functional electrode 71 is located, away from the first conductive layer. The first functional electrode 71 is electrically connected to the first connecting line 80, and the second functional electrode 72 is electrically connected to the second connecting line 73. Therefore, the distance between the second connecting line 73 and the first connecting line 80 can be further increased to reduce signal interference between the second connecting line 73 and the first connecting line 80. The second functional electrode 72 and the second connecting line 73 are electrically connected and provided in the same layer to reduce the number of vias. In other embodiments, the second functional electrode 72 and the second connecting line 73 can also be provided in different layers.

[0088] In these optional embodiments, through the above settings, when the first functional electrode 71 is a touch electrode 711, the touch electrode 711 and the corresponding connecting wires can be set using the wiring method in the relevant technology to simplify the manufacturing process of the first functional electrode 71 and the corresponding connecting wires.

[0089] Figure 3 This is a schematic diagram of the cross-sectional structure of another display panel provided in an embodiment of the present application.

[0090] In some embodiments, as Figure 3 As shown, the first functional layer 70 further includes a first shielding portion 74, and the film layer where the first shielding portion 74 is located is located between the film layer where the first connecting line 80 is located and the film layer where the second connecting line 73 is located. Optionally, the display panel further includes a substrate 10, and the overlapping area of ​​the orthographic projection of the first connecting line 80 on the substrate 10 and the orthographic projection of the second connecting line 73 on the substrate 10 overlaps with the orthographic projection of the first shielding portion 74 on the substrate 10.

[0091] The first shielding portion 74 , the first connecting line 80 , and the second connecting line 73 are provided in different film layers, and the first shielding portion 74 is located between the first connecting line 80 and the second connecting line 73 .

[0092] The orthographic projection of the first connecting line 80 on the substrate 10 and the orthographic projection of the second connecting line 73 on the substrate 10 may only partially overlap. Of course, the orthographic projection of the first connecting line 80 on the substrate 10 and the orthographic projection of the second connecting line 73 on the substrate 10 may also overlap. The overlapping area or the overlapping area is located within the orthographic projection of the first shielding portion on the substrate and is less than or equal to the orthographic projection area of ​​the first shielding portion on the substrate.

[0093] In these optional embodiments, through the above-mentioned arrangement, the first connecting line 80 and the second connecting line 73 are located on the upper and lower sides of the first shielding portion 74, so that the first shielding portion 74 can play a shielding role between the first connecting line 80 and the second connecting line 73, further reducing the possibility of mutual interference between the signal in the first connecting line 80 and the signal in the second connecting line 73.

[0094] In some embodiments, the first shielding portion 74 is electrically connected to a power line or a ground line. The first shielding portion 74 is electrically connected to a DC potential line. The display panel may include a pixel circuit, and a first high-voltage power line, a first low-voltage power line, an initialization signal line, etc. connected to the pixel circuit. The first shielding portion 74 may be electrically connected to the first high-voltage power line, the first low-voltage power line, or the initialization signal line connected to the pixel circuit. The display panel may include a scanning circuit, which is electrically connected to the pixel circuit via a scanning line. The first shielding portion 74 may be electrically connected to a second high-voltage power line, a second low-voltage power line, etc. connected to the scanning circuit. Alternatively, the first shielding portion 74 may be electrically connected to an additionally provided DC potential line.

[0095] In these optional embodiments, the first shielding portion 74 is electrically connected to a power line or a ground line, so that the first shielding portion 74 can have a fixed-level signal, thereby improving the reliability of the shielding function of the first shielding portion 74. In addition, the connection between the first shielding portion 74 and other wiring can be simplified, shortening the connection line.

[0096] In some embodiments, the overlapping area of ​​the orthographic projection of the first connecting line 80 on the substrate 10 and the orthographic projection of the second connecting line 73 on the substrate 10 is located within the orthographic projection of the first shielding portion 74 on the substrate 10. In other words, the area of ​​the overlapping area of ​​the orthographic projection of the first connecting line 80 on the substrate 10 and the orthographic projection of the second connecting line 73 on the substrate 10 is less than or equal to the orthographic projection area of ​​the first shielding portion 74 on the substrate 10, so as to further improve the shielding effect of the first shielding portion 74 and reduce the possibility that the overlapping area of ​​part of the first connecting line 80 and the second connecting line 73 exceeds the orthographic projection area of ​​the first shielding portion 74 on the substrate 10 due to process errors.

[0097] In some embodiments, one of the first functional electrode 71 and the second functional electrode 72 is disposed on the same layer as the first shielding portion 74. One of the first functional electrode 71 and the second functional electrode 72 is disposed on the same layer as the first shielding portion 74, and the other is disposed on the same layer as the second connecting line 73. The film layer where the second connecting line 73 is located is located on the side of the film layer where the first shielding portion 74 is located away from the substrate 10.

[0098] Multiple structures arranged on the same layer can be obtained by patterning the same film layer, thereby simplifying the process.

[0099] In some examples, the first functional electrode 71 is disposed on the same layer as the first shielding portion 74. In other examples, the second functional electrode 72 is disposed on the same layer as the first shielding portion 74.

[0100] Furthermore, the second connecting line 73 and the first functional electrode 71 are provided on the same layer, and the second functional electrode 72 and the first shielding portion 74 are provided on the same layer.

[0101] In these optional embodiments, the above configuration is used to reduce the number of manufacturing steps of the first shielding portion 74 , thereby reducing the overall manufacturing steps of the display panel and lowering the manufacturing cost.

[0102] In some embodiments, as Figure 2As shown, the film layer containing the pressure-sensing electrodes 721 is located on the side of the film layer containing the touch electrodes 711 that faces the substrate 10. That is, in the thickness direction Z, the substrate 10, the film layer containing the pressure-sensing electrodes 721, and the film layer containing the touch electrodes 711 are stacked sequentially. As can be seen from the foregoing, in the thickness direction Z, the substrate 10, the film layer containing the first connecting wires 80, and the film layer containing the second connecting wires 73 are sequentially arranged. Arranging the pressure-sensing electrodes 721 and the touch electrodes 711 in this manner can reduce the difficulty of connecting the first connecting wires 80 and the pressure-sensing electrodes 721, while also reducing the difficulty of connecting the second connecting wires 73 and the touch electrodes 711. This simplifies the process, improves the manufacturing yield, and reduces the number of vias.

[0104] In some embodiments, as Figures 2 to 5 As shown, the second connecting wires 73 are electrically connected to the touch electrodes 711, the first connecting wires 80 are electrically connected to the pressure sensing electrodes 721, the second connecting wires 73 and the touch electrodes 711 are provided on the same layer, and the first shielding portion 74 and the pressure sensing electrodes 721 are provided on the same layer. In other words, the second connecting wires 73 and the touch electrodes 711 are manufactured in a single process, and the second connecting wires 73 and the pressure sensing electrodes 721 are manufactured in a single process, thereby reducing process steps and improving production efficiency.

[0105] Figure 6 This is a schematic diagram of the cross-sectional structure of another display panel provided in an embodiment of the present application.

[0106] In some embodiments, as Figures 3 to 6 As shown, at least one touch electrode 711 includes multiple touch electrode blocks, at least two adjacent touch electrode blocks are interconnected via a bridge portion 712, and the bridge portion 712 and the touch electrode blocks are arranged in different layers. The bridge portion 712 and the pressure sensing electrode 721 are arranged in the same layer.

[0107] Alternatively, as Figure 6 As shown, the first functional layer 70 includes a first film layer M1 and a second film layer M2 stacked in sequence in a direction away from the first conductive layer (or substrate 10 ), the touch electrode block is disposed in the second film layer M2 , and the bridge portion 712 is disposed in the first film layer M1 .

[0108] In the display panel, the touch electrodes 711 include a plurality of first touch electrode blocks 711a and a plurality of second touch electrode blocks 711b. The plurality of first touch electrode blocks 711a can be sequentially distributed along a first direction Y to form a touch column, with the first touch electrode blocks 711a in the same touch column electrically connected. The plurality of second touch electrode blocks 711b can be sequentially distributed along a second direction X to form a touch row. The plurality of second touch electrode blocks 711b in the same touch row, sequentially distributed along the second direction X, are electrically connected to each other, with the connecting portions between the second touch electrode blocks 711b being disposed on the same layer as the second touch electrode blocks 711b. The first touch electrode blocks 711a and the second touch electrode blocks 711b have overlapping regions, requiring bridges 712 to electrically connect the first touch electrode blocks 711a in the same column. For example, two adjacent first touch electrode blocks 711a are electrically connected via the bridges 712. The first touch electrode block 711 a and the second touch electrode block 711 b are arranged on the same layer, and the bridge portion 712 and the touch electrode 711 are arranged on different layers.

[0109] Optionally, the orthographic projection of the touch electrode block on the substrate 10 may at least partially overlap with the orthographic projection of the pressure sensing electrode 721 on the substrate 10. For example, the orthographic projection of the first touch electrode block 711a on the substrate 10 may at least partially overlap with the orthographic projection of the pressure sensing electrode 721 on the substrate 10, or the orthographic projection of the second touch electrode block 711b on the substrate 10 may at least partially overlap with the orthographic projection of the pressure sensing electrode 721 on the substrate 10.

[0110] like Figure 3 and Figure 5 As shown, the bridge portion 712 is provided in the same layer as the pressure sensing electrode 721. Optionally, the bridge portion 712 is located between two adjacent pressure sensing electrodes 721. For example, the bridge portion 712 is located between two adjacent pressure sensing electrodes 721 that are connected to each other (e.g., Figure 5 Alternatively, the bridge portion 712 is located between two adjacent pressure sensing electrodes 721 that are insulated from each other.

[0111] like Figure 6 As shown, the first functional layer 70 includes a first film layer M1 and a second film layer M2. The first touch electrode block 711a and the second touch electrode block 711b are both located in the second film layer M2. The bridge portion 712 is located in the first film layer M1. The first film layer M1 and the second film layer M2 are insulated.

[0112] In these optional embodiments, through the above configuration, while realizing the touch function of the touch electrode 711 , the thickness of the entire film layer is reduced, thereby achieving a lighter and thinner display panel.

[0113] Figure 7FIG. 1 is a schematic diagram of a cross-sectional structure of another display panel provided in an embodiment of the present application. In some embodiments, Figure 7 As shown, the first functional layer 70 includes a first film layer M1 and a second film layer M2. The second connecting line 73 includes a first branch circuit E1 located in the first film layer M1 and a second branch circuit E2 located in the second film layer M2. The overlapping region of the orthographic projection of the first branch circuit on the substrate and the orthographic projection of the first connecting line on the substrate overlaps with the orthographic projection of the first shielding portion on the substrate. The first shielding portion reduces signal interference between the first branch circuit and the first connecting line. The overlapping region of the orthographic projection of the second branch circuit on the substrate and the orthographic projection of the first connecting line on the substrate overlaps with the orthographic projection of the first shielding portion on the substrate. The first shielding portion reduces signal interference between the second branch circuit and the first connecting line.

[0114] Optionally, there are multiple second connection lines 73 , and the multiple second connection lines 73 are distributed at least in two opposite frames of the display panel.

[0115] The second connecting line 73 includes a first branch circuit E1 and a second branch circuit E2. Optionally, both the first branch circuit E1 and the second branch circuit E2 are electrically connected to the touch electrode blocks. For example, both the first branch circuit E1 and the second branch circuit E2 are electrically connected to the first touch electrode block 711a. And / or both the first branch circuit E1 and the second branch circuit E2 are electrically connected to the second touch electrode block 711b. Optionally, the first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be electrically connected to the same touch electrode block. Alternatively, both ends of a row of touch electrode blocks are electrically connected to the corresponding first branch circuit E1 and second branch circuit E2, respectively.

[0116] The first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be arranged on the same layer or on different layers. The first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be located in the same frame, or the first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be located in different frames, such as opposite frames. The first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be electrically connected to the same touch electrode block.

[0117] The first branch circuit E1 and the second branch circuit E2 of the same second connecting line can be arranged in different layers. The overlapping area of ​​the orthographic projection of the first branch circuit E1 and the orthographic projection of the second branch circuit E2 on the substrate 10 overlaps with the orthographic projection of the first shielding portion 74 on the substrate 10.

[0118] In some examples, the orthographic projection of the first branch circuit E1 on the substrate 10 and the orthographic projection of the first connecting line 80 on the substrate 10 may only partially overlap. Of course, the orthographic projection of the first branch circuit E1 on the substrate 10 and the orthographic projection of the first connecting line 80 on the substrate 10 may also overlap. The overlapping area or the overlapping area is located within the orthographic projection of the first shielding portion 74 on the substrate 10 and is less than or equal to the orthographic projection area of ​​the first shielding portion 74 on the substrate 10.

[0119] In some examples, the orthographic projection of the second branch circuit E2 on the substrate 10 and the orthographic projection of the first connecting line 80 on the substrate 10 may only partially overlap. Of course, the orthographic projection of the second branch circuit E2 on the substrate 10 and the orthographic projection of the first connecting line 80 on the substrate 10 may also overlap. The overlapping area or the overlapping area is located within the orthographic projection of the first shielding portion 74 on the substrate 10 and is less than or equal to the orthographic projection area of ​​the first shielding portion 74 on the substrate 10.

[0120] In some examples, at least one of the plurality of second connection lines 73 is located on one side of the display panel, and at least one second connection line 73 is located on the other side of the display panel. Alternatively, the plurality of second connection lines 73 may be provided on the left and right opposite sides of the display panel. Of course, the plurality of second connection lines 73 may also be provided on the upper and lower opposite sides of the display panel.

[0121] In these optional embodiments, the first branch circuit E1 and the second branch circuit E2 are provided to reduce the impedance of the second connecting line 73 or enhance the signal strength, thereby improving touch sensitivity. The orthographic projections of the first branch circuit E1 and the second branch circuit E2 on the substrate 10 are both located within the orthographic projection of the first shielding portion 74 on the substrate 10, thereby enhancing the shielding effect of the first shielding portion 74 and reducing the impact of the pressure sensing signal on the second connecting line 73. The second connecting line 73 can be electrically connected to the touch control chip.

[0122] Figure 8 Schematic diagram of a top view structure of another display panel provided in an embodiment of the present application. Figure 8 As shown, the first shielding portion 74 is provided in a ring shape around the first functional electrode 71 or the second functional electrode 72 .

[0123] Optionally, the orthographic projection shape of the first shielding portion 74 on the substrate 10 may match the outline shape of the non-display area NA. For example, if the outline shape of the non-display area NA is rectangular, the orthographic projection shape of the first shielding portion 74 on the substrate 10 may be a rectangular ring. Of course, the orthographic projection shape of the first shielding portion 74 on the substrate 10 may also be any shape.

[0124] Optionally, when the first shielding portion 74 and the first functional electrode 71 are disposed in the same layer, the first shielding portion 74 is disposed around the first functional electrode 71 . When the first shielding portion 74 and the second functional electrode 72 are disposed in the same layer, the first shielding portion 74 is disposed around the second functional electrode 72 .

[0125] Optionally, the orthographic projection of the first shielding portion 74 on the substrate 10 includes a continuous closed shape, that is, the first shielding portion 74 is an integrated structure, which reduces the number of connection lines between the first shielding portion 74 and the external circuit, thereby reducing the difficulty of the manufacturing process and improving production efficiency.

[0126] Figure 9 FIG. 1 is a schematic diagram of a cross-sectional structure of another display panel provided in an embodiment of the present application. In some embodiments, Figure 9 As shown, the display panel also includes a light-emitting device layer. The light-emitting device layer includes a first electrode layer 20, a light-emitting layer 40, and a second electrode layer 50. The first electrode layer 20 is located on one side of the substrate 10. The light-emitting layer 40 includes a plurality of light-emitting units 41, and the isolation structure 60 is at least partially located between the light-emitting units 41. The second electrode layer 50 is located on the side of the light-emitting unit 41 facing away from the first electrode layer 20.

[0127] The isolation structure 60 is at least partially located between the light-emitting units 41. Optionally, the isolation structure 60 can enclose a plurality of isolation openings 64, and at least a portion of the light-emitting units 41 is disposed within the plurality of isolation openings 64, that is, the orthographic projection of the light-emitting unit 41 on the substrate 10 is at least partially located within the orthographic projection of the isolation opening 64 on the substrate 10.

[0128] The light-emitting layer 40 is located on one side of the substrate 10 and includes a plurality of light-emitting units 41 in a direction parallel to the plane of the substrate 10. The light-emitting unit 41 is the main device for realizing the light-emitting display. In some embodiments, a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL) may be stacked between the first electrode layer and the second electrode layer.

[0129] Optionally, the first electrode layer 20 includes multiple first electrodes 21 , the multiple first electrodes 21 and the multiple isolation openings 64 are correspondingly arranged, each first electrode 21 and each light-emitting unit 41 are correspondingly arranged, and the first electrode 21 is located on the side of each light-emitting unit 41 facing the substrate 10 .

[0130] Optionally, the second electrode layer 50 includes multiple second electrodes, the multiple second electrodes are correspondingly arranged with the multiple isolation openings 64 , each second electrode is correspondingly arranged with each light-emitting unit 41 , and the second electrode is located on the side of each light-emitting unit 41 facing away from the substrate 10 .

[0131] In some examples, the second electrode layer 50 is electrically connected to the isolation structure 60 .

[0132] Optionally, at least part of the isolation structure 60 is made of a conductive material, and the second electrode and the isolation structure 60 are conductively connected, so that the plurality of second electrodes can be interconnected through the isolation structure 60 to form a full-surface electrode.

[0133] In these optional embodiments, the isolation opening 64 can be used for the production of the light-emitting unit 41 and the production of the second electrode. For example, the light-emitting unit 41 includes light-emitting units 41 of multiple different colors. When producing light-emitting units 41 of the same color in the isolation opening 64, the corresponding second electrode can be produced together in the isolation opening 64, so as to achieve patterning of the light-emitting layer and the second electrode layer through the isolation effect of the isolation structure.

[0134] In some embodiments, one of the first electrode layer 20 and the second electrode layer 50 is an anode layer, and the other is a cathode layer.

[0135] Optionally, the first electrode layer 20 is an anode layer, and the second electrode layer 50 is a cathode layer. Of course, the first electrode layer 20 can also be a cathode layer, and the second electrode layer 50 can also be an anode layer.

[0136] In some embodiments, as Figure 9 As shown, the first functional layer 70 further includes a first shielding portion 74 , and at least one of the second electrode layer 50 and the isolation structure 60 is electrically connected to the first shielding portion 74 .

[0137] In some examples, the second electrode layer 50 is electrically connected to the first shield portion 74. In other examples, the isolation structure 60 is electrically connected to the first shield portion 74. In still other examples, both the second electrode layer 50 and the isolation structure 60 are electrically connected to the first shield portion 74.

[0138] In some examples, at least one of the second electrode layer 50 and the first shielding portion 74 needs to be electrically connected to a control chip in the display device through a connecting wire, and the first shielding portion 74 can also be electrically connected to the second electrode layer 50 or the isolation structure 60 through a connecting wire.

[0139] In these optional embodiments, the second electrode layer 50 and the isolation structure 60 can be electrically connected to each other, and the second electrode layer 50 can provide a fixed-level signal. By electrically connecting the first shielding portion 74 to the second electrode layer 50 and / or the isolation structure 60, the first shielding portion 74 can carry the same fixed-level signal, thereby improving the shielding effect of the first shielding portion 74.

[0140] Figure 10 This is a schematic diagram of the cross-sectional structure of another display panel provided in an embodiment of the present application.

[0141] In some embodiments, as Figure 10 As shown, the first electrode layer 20 further includes a second shielding portion 22 located in the non-display area NA. The display panel further includes a driving circuit layer 11 . The film layer where the second shielding portion 22 is located is located between the driving circuit layer 11 and the film layer where the first connecting line 80 is located.

[0142] Optionally, the drive circuit layer 11 may include a scanning circuit located in the non-display area NA and a pixel circuit located in the display area AA. The scanning circuit may include a multi-stage shift register, etc. The drive circuit layer may be used to form the gate, source, drain, and plate of the transistor in the pixel circuit, as well as the scan line, data line, power line, transistor and capacitor in the scanning circuit, etc. The drive circuit layer may include a gate layer, a capacitor plate layer, a source and drain layer, etc.

[0143] In some examples, the first electrode layer 20 is an anode layer, and the first electrode 21 included in the first electrode layer 20 is located in the display area AA. Of course, the portion of the first electrode layer 20 located in the non-display area NA may not be provided with the light-emitting unit 41, so the first electrode 21 does not need to be provided in the non-display area NA. To improve integration, a second shielding portion 22 may be provided in the portion of the first electrode layer 20 located in the non-display area NA. The second shielding portion 22 and the first electrode 21 are layered together. The second shielding portion 22 can shield signals between the scanning circuit and the first functional layer in the driver circuit layer 11. For example, the second shielding portion 22 can shield signals between the scanning circuit and the first connecting line 80. Electrically connecting the second shielding portion 22 to the first shielding portion 74 can reduce the difficulty of routing shielding signals in the non-display area NA, simplify the connection between the shielding signal routing and the metal layer in the display area AA, and reduce manufacturing complexity. Optionally, the second shielding portion 22 and the first shielding portion 74 can be electrically connected via a via.

[0144] In some embodiments, the second shielding portion 22 is electrically connected to a power line or a ground line, so that the first shielding portion 74 can have a fixed level signal, thereby improving the reliability of the shielding effect of the second shielding portion 22 .

[0145] The second shielding portion 22 can be electrically connected to a DC potential line. The second shielding portion 22 can be electrically connected to a first high-voltage power line, a first low-voltage power line, or an initialization signal line connected to the pixel circuit. The display panel may include a scanning circuit electrically connected to the pixel circuit via the scanning lines. The second shielding portion 22 can be electrically connected to a second high-voltage power line, a second low-voltage power line, or the like connected to the scanning circuit. Alternatively, the second shielding portion 22 can be electrically connected to an additionally provided DC potential line.

[0146] Figure 11 This is a schematic diagram of a top view structure of another display panel provided in an embodiment of the present application.

[0147] In some embodiments, as Figure 11 As shown, the display panel may include a driver chip and / or a touch chip IC, the driver chip may be electrically connected to the scanning circuit and the data line, and the touch chip IC may be electrically connected to the touch electrode 711. The first shielding portion 74 may be directly electrically connected to the driver chip or the touch chip IC.

[0148] Optionally, the touch control chip IC and the driver chip may be integrated together. Of course, the touch control chip IC and the driver chip may also be separate structures.

[0149] In these optional embodiments, by electrically connecting the first shielding portion 74 and the touch chip IC, the first shielding portion 74 does not need to be electrically connected to the circuits in the driving circuit layer 11, thereby simplifying the layout difficulty of the first shielding portion 74. In addition, the direct electrical connection between the first shielding portion 74 and the touch chip IC can also improve the reliability of the shielding effect of the first shielding portion 74 and reduce the possibility that the first shielding portion 74 cannot provide a shielding effect when other circuits are damaged or fail.

[0150] Figure 12 This is a schematic diagram of the cross-sectional structure of another display panel provided in an embodiment of the present application.

[0151] In some embodiments, as Figure 12 As shown, the display panel further includes a substrate 10 and a pixel definition layer 30 disposed on one side of the substrate 10 . The pixel definition layer 30 includes a pixel defining portion 31 and a pixel opening surrounded by the pixel defining portion 31 .

[0152] Optionally, a plurality of light emitting units 41 are disposed in a plurality of pixel openings, wherein the light emitting units 41 in different pixel openings may be spaced apart from each other.

[0153] Further optionally, the isolation structure 60 is located on the side of the pixel defining portion 31 facing away from the substrate 10 , or a clearance opening is opened on the pixel defining portion 31 , and the isolation structure 60 is located in the clearance opening.

[0154] Optionally, the isolation structure 60 is located on the side of the pixel defining portion 31 facing away from the substrate 10. That is, the isolation opening 64 formed by the isolation structure 60 is located on the side of the pixel opening facing away from the substrate 10. The isolation structure 60 is located within the clearance opening. The clearance opening is formed by a surface depression on the side of the pixel defining portion 31 facing away from the substrate 10. The depth of the depression of the clearance opening can be recessed to a predetermined position of the pixel defining portion 31. For example, the depth of the depression of the clearance opening can be half the thickness of the pixel defining portion 31. The location of the isolation structure 60 within the clearance opening can reduce the space occupied by the isolation structure 60 in the thickness direction Z of the display panel, thereby facilitating a thinner and lighter display panel.

[0155] In some embodiments, as Figure 12 As shown, the display panel includes a substrate 10, and the isolation structure 60 includes a first isolation portion 61 and a second isolation portion 62 stacked in sequence in a direction away from the substrate 10. The orthographic projection of the first isolation portion 61 on the substrate 10 is located within the orthographic projection of the second isolation portion 62 on the substrate 10. The area of ​​the orthographic projection of the first isolation portion 61 on the substrate 10 is smaller than the area of ​​the orthographic projection of the second isolation portion 62 on the substrate 10.

[0156] This design helps to make it difficult for the luminescent material to extend along the side wall of the first isolation part 61 to the side wall of the second isolation part 62 during the preparation of the light-emitting functional layer, thereby realizing the preparation and mutual separation of light-emitting structures in different opening structures without the need for a fine metal mask plate.

[0157] The embodiment of the present application does not limit the specific structural dimensions of the first isolation portion 61 and the second isolation portion 62. For example, the longitudinal cross-section of the isolation structure 60 may be similar to a T-shaped structure.

[0158] The orthographic projection of the first isolation portion 61 on the substrate 10 is smaller than that of the second isolation portion 62 , and usually, the orthographic projection of the first isolation portion 61 on the substrate 10 is located at the center of the orthographic projection of the isolation structure 60 on the substrate 10 .

[0159] Optionally, the first connection line 80 is at least provided at the same layer as the first isolation portion 61 , or the first connection line 80 is at least provided at the same layer as the second isolation portion 62 .

[0160] For example, the first connecting line 80 is disposed only on the same layer as the first isolating portion 61. Alternatively, the first connecting line 80 is disposed only on the same layer as the second isolating portion 62. Alternatively, a portion of the first connecting line 80 is disposed on the same layer as the first isolating portion 61, and another portion of the first connecting line 80 is disposed on the same layer as the second isolating portion 62.

[0161] On this basis, the embodiment of the present application sets the first connecting line 80 and the second isolation part 62 or the first isolation part 61 on the same layer, which is beneficial to reducing the distance between the first connecting line 80 and the pressure sensing electrode 721 and reducing the possibility of interference between the first connecting line 80 and other lines.

[0162] In some embodiments, see Figure 9 The display panel includes a substrate 10, and the isolation structure 60 includes a third isolation portion 63, a first isolation portion 61, and a second isolation portion 62, which are stacked in sequence in a direction away from the substrate 10. The orthographic projection of the first isolation portion 61 on the substrate 10 is located within the orthographic projection of the second isolation portion 62 on the substrate 10, and the orthographic projection of the first isolation portion 61 on the substrate 10 is located within the orthographic projection of the third isolation portion 63 on the substrate 10.

[0163] The third isolation portion 63 may also include a conductive material, and the second electrode may cover a portion of the third isolation portion 63 to achieve electrical connection therebetween, thereby improving the reliability of the electrical connection between the second electrode and the isolation structure 60 .

[0164] The orthographic projection of the first isolation portion 61 on the substrate 10 is located within the orthographic projection of the third isolation portion 63 on the substrate 10 . The orthographic projection area of ​​the first isolation portion 61 on the substrate 10 is smaller than the orthographic projection area of ​​the third isolation portion 63 on the substrate 10 .

[0165] Furthermore, the first connecting line 80 may also be provided on the same layer as the third isolating portion 63. Alternatively, the first connecting line 80 may include two or three parts. When the first connecting line 80 includes two parts, the two parts may be provided on the same layer as any two of the first isolating portion 61, the second isolating portion 62, and the third isolating portion 63. When the first connecting line 80 includes three parts, the three parts may be provided on the same layer as the first isolating portion 61, the second isolating portion 62, and the third isolating portion 63, respectively.

[0166] Optionally, the area of ​​the orthographic projection of the first isolating portion 61 on the substrate 10 is smaller than the area of ​​the orthographic projection of the second isolating portion 62 on the substrate 10, and the area of ​​the orthographic projection of the first isolating portion 61 on the substrate 10 is smaller than the area of ​​the orthographic projection of the third isolating portion 63 on the substrate 10. For example, the longitudinal cross-section of the isolation structure 60 formed by the third isolating portion 63, the first isolating portion 61, and the third isolating portion 63 may be in the shape of an I-beam.

[0167] Figure 13 This is a schematic diagram of the cross-sectional structure of another display panel provided in an embodiment of the present application.

[0168] In some embodiments, as Figure 13 As shown, the display panel further includes an encapsulation layer 90 , which is located between the first conductive layer and the first functional layer 70 .

[0169] Optionally, the encapsulation layer 90 includes a first encapsulation layer 91, which includes a plurality of first encapsulation portions. The isolation structure 60 encloses a plurality of isolation openings 64. The display panel further includes a light-emitting device layer. The first encapsulation layer 91 is located between the light-emitting device layer and the first conductive layer. The light-emitting device layer includes a plurality of light-emitting devices, at least partially located within the isolation openings 64. The first encapsulation portions cover the corresponding light-emitting devices. The light-emitting devices may include a first electrode, a light-emitting unit, and a second electrode.

[0170] In some examples, the isolation structure 60 encloses a plurality of isolation openings 64, and the side walls of each isolation opening 64 are formed by the side walls of the first isolation portion 61 and the side walls of the second isolation portion 62. The side walls of the first isolation portion 61 and the side walls of the second isolation portion 62 make it difficult for the light-emitting material forming the light-emitting unit 41 to extend along the side walls of the first isolation portion 61 to the side walls of the second isolation portion 62, so that the light-emitting material is disconnected at the connection between the first isolation portion 61 and the second isolation portion 62. In the production of light-emitting units 41 of different colors, light-emitting units 41 of different colors need to be prepared multiple times. For example, in the production of the first color light-emitting unit 41, the light-emitting material of the first color can be set on the entire surface of the display panel, and then multiple first packaging parts are formed in the isolation opening 64. After the first color light-emitting unit 41 is completed, the first light-emitting unit 41 and the corresponding first packaging part in the isolation opening 64 corresponding to the other color light-emitting units 41 are removed, and then the production process of the first color light-emitting unit 41 is repeated until the light-emitting unit 41 of each color is completed.

[0171] Optionally, the encapsulation layer 90 further includes an organic encapsulation layer 92, which is located on a side of the first conductive layer and the first encapsulation layer 91 that is close to the first functional layer 70. That is, the organic encapsulation layer 92 can be located on a side of the first encapsulation layer 91 that is away from the substrate 10. Optionally, the organic encapsulation layer 92 can be provided only in the display area AA. Of course, the organic encapsulation layer 92 can also be provided in the display area AA and a portion of the non-display area NA.

[0172] Optionally, the encapsulation layer 90 further includes a second encapsulation layer 93 located between the organic encapsulation layer 92 and the first functional layer 70. That is, the first encapsulation layer 91, the organic encapsulation layer 92 and the second encapsulation layer 93 form a three-layer encapsulation structure.

[0173] Optionally, the first encapsulation layer 91 is an inorganic layer, and the second encapsulation layer 93 is an inorganic layer. This design can set the encapsulation layer 90 to a three-layer structure of inorganic, organic and inorganic, so that the encapsulation layer 90 can be a thin film encapsulation structure, which helps to improve the encapsulation performance of the encapsulation layer 90, thereby improving the encapsulation protection effect of the encapsulation layer 90 on the light-emitting structure.

[0174] In some examples, in the non-display area NA, a first encapsulation layer 91 and / or a second encapsulation layer 93 is disposed between the first connection line 80 and the second connection line 73 .

[0175] Optionally, only the first encapsulation layer 91 may be provided between the first connection line 80 and the second connection line 73; or, only the second encapsulation layer 93 may be provided between the first connection line 80 and the second connection line 73; or both the first encapsulation layer 91 and the second encapsulation layer 93 may be provided between the first connection line 80 and the second connection line 73.

[0176] In these optional embodiments, through the above-mentioned settings, the encapsulation layer 90 can be an insulating layer, and the first encapsulation layer 91 and / or the second encapsulation layer 93 can be an insulating layer, which is beneficial to increase the distance between the first connecting line 80 and the second connecting line 73, and reduce the possibility of mutual interference between the signal in the first connecting line 80 and the signal in the second connecting line 73.
