[0073] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0074] Figure 1 A schematic diagram of a display panel according to an embodiment of the present invention is shown in FIG. Figure 1 The display panel includes a first display area AA1 and a second display area AA2, the second display area AA2 at least partially surrounds the first display area AA1, and the transmittance of the first display area AA1 is greater than the transmittance of the second display area AA2.

[0075] Specifically, the second display area AA2 can be set on one side of the first display area AA1, or it can partially or completely surround the first display area AA1. The first display area AA1 can be used as an under-screen camera area (UDC). The transmittance of the first display area AA1 is greater than the transmittance of the second display area AA2. The setting position of the first display area AA1 can correspond to the position of the sensor device under the screen. The correspondence here means that the orthographic projection of the sensor device under the screen on the display panel overlaps with the first display area AA1 at least partially or completely, that is, the orthographic projection of the sensor device under the screen on the display panel is partially located in the first display area AA1, or is completely located in the first display area AA1. Thereby, more light can be received by the sensor device through the first display area AA1. Exemplarily, the sensor device may include a camera device, a light sensor, an ultrasonic sensor, a fingerprint sensor, and a radar sensor. The second display area AA2 can be a normal display area, wherein the resolution of the first display area AA1 and the resolution of the second display area AA2 can be the same or different, and the shape of the first display area AA1 can be circular, rectangular, square, diamond, etc., which is not limited here.

[0076] Figure 2 A schematic diagram of a cross-sectional structure of a display panel AA' provided in an embodiment of the present invention, referring to the figure, the display panel comprises: a substrate 110; a first wiring layer 310, which is arranged on one side of the substrate 110 and located in the first display area AA1;

[0077] A plurality of light-emitting units are disposed on one side of the substrate 110 and are located in the first display area and the second display area. The light-emitting units include a first electrode 131 and a second electrode 511.

[0078] One of the routing lines in the first routing layer 310 is connected to at least two first electrodes 131 located in the first display area AA1 , and / or one of the routing lines in the first routing layer 310 is connected to at least two second electrodes 511 located in the first display area AA1 .

[0079] Specifically, according to the material of the substrate 110, the substrate 110 may be a flexible substrate 110, such as a polyimide substrate 110, or a rigid substrate 110, such as a glass substrate 110. The anode layer 130 is provided with a plurality of first electrodes 131, and the plurality of first electrodes 131 are arranged at intervals. A light-emitting functional layer is arranged in the pixel opening S1, and the exposed first electrode 131 in the pixel opening S1 is connected to the light-emitting functional layer 510. A second electrode 511 is arranged on the side of the light-emitting functional layer away from the substrate 110, and the first electrode 131, the light-emitting functional layer and the second electrode 511 form a light-emitting unit. Among them, the first electrode 131 can serve as the anode of the light-emitting unit and is connected to the driving circuit layer. The driving current formed in the driving circuit layer can provide a driving signal for the anode of the light-emitting unit, and the second electrode can serve as the cathode of the light-emitting unit.

[0080] In order to improve the light transmittance of the first display area AA1, a first wiring layer 310 is provided on one side of the substrate 110, and the first wiring layer 310 can form corresponding wiring by patterning the design, and the first electrodes 131 between different light-emitting units in the first display area AA1 are connected by wiring, and / or the second electrodes 511 between different light-emitting units in the first display area AA1 are connected by wiring, so that the light-emitting units share anode signals and / or cathode signals, thereby reducing the anode wiring and / or cathode wiring in the corresponding first display area AA1, which is beneficial to improving the light transmittance of the first display area AA1. Exemplarily, Figure 2 As shown, at least two first electrodes 131 of the first display area are connected through a wiring in the first wiring layer 310, that is, the first electrodes 130 between the light-emitting units are connected, so that a group of anode signals can be shared, and thus a group of driving circuits can be shared, thereby reducing the structural layout of the driving circuit and further improving the transmittance of the first display area AA1.

[0081] In an embodiment of the present invention, a first routing layer is set between the substrate and the isolation structure, and at least two first electrodes and / or at least two second electrodes are connected by the first routing layer, so that the same driving signal can drive multiple light-emitting units in the first display area, thereby reducing the number of wirings in the first display area and improving the transmittance of the first display area.

[0082] In some embodiments, the second electrode 511 may adopt fine metal mask technology (Fane Metal Mask, FFM) to form the second electrode 511 spaced apart in the first display area AA1 and / or the second display area AA2, and at least two second electrodes 511 may be connected through a wiring in the first wiring layer, that is, at least two second electrodes 511 are connected between the light-emitting units, and a set of cathode signals may be shared, thereby reducing the shading area of ​​the cathode in the first display area AA1, and further improving the transmittance of the first display area AA1. In some cases, the first electrodes between different light-emitting units in the first display area AA1 may be connected through the second wiring structure according to wiring requirements, and the light-emitting units may realize a common anode signal, reducing the number of wirings in the first display area, thereby improving the transmittance of the first display area.

[0083] In some embodiments, Figure 3 A schematic diagram of a cross-sectional structure of another display panel AA' provided in an embodiment of the present invention, see Figure 3 The display panel also includes an isolation layer, including a plurality of first isolation structures 140 located in the first display area, the first isolation structures 140 enclose a first isolation opening, and the second electrode of the light-emitting unit arranged in the first display area AA1 is located in the corresponding first isolation opening and is electrically connected to the corresponding first isolation structure 140; wherein the first wiring layer includes at least one first wiring structure 311, and at least one first wiring structure 311 connects at least two first isolation structures 140.

[0084] Specifically, the first isolation structure 140 encloses and forms a first isolation opening, the first isolation opening is connected to the pixel opening S1, the first isolation structure 140 is insulated from the first electrode 131, and the first isolation structure 140 is connected to the second electrode, and a cathode power supply signal can be provided to the second electrode 511 through the first isolation structure 140. The first isolation structure 140 can be used as a mask when manufacturing the light-emitting functional layer, thereby saving the use of the mask and reducing the manufacturing cost of the display panel. At the same time, the distance requirement between adjacent pixel openings S1 can be reduced, which is conducive to improving the pixel density of the display panel, and the first isolation structure 140 can be used to form an independent light-emitting unit, and the performance of each light-emitting unit can be independently adjusted.

[0085] A first wiring layer 310 is provided between the substrate 110 and the first isolation structure 140. The first wiring layer includes at least one first wiring structure. Exemplarily, a first wiring structure 311 is formed by patterning the first wiring layer 310. Different first isolation structures 140 are connected by the first wiring structure 311, so that an electrical connection is formed between the first isolation structures 140 to achieve cathode signal transmission of the first display area AA1. It should be noted that the first wiring layer 310 is insulated from other metal layers. In order to improve the light transmittance of the first display area AA1, the first wiring layer 310 can be made of a transparent conductive material, such as indium tin oxide (ITO). The embodiment of the present invention sets a first wiring layer 310 between the substrate and the isolation structure, and uses the first wiring layer 310 to connect different first isolation structures 140, so as to realize power signal transmission in the first display area. Compared with the second electrode 511 using fine metal mask technology, the first isolation structure 140 arranged at intervals can reduce the shielding area in the first display area AA1, thereby improving the transmittance of the first display area AA1.

[0086] Based on the above embodiment, the first isolation structure 140 of the first display area AA1 can also be an integrated structure, that is, different first isolation structures 140 are connected to form a mesh-connected first isolation structure 140. Since the second electrode is located in the corresponding first isolation opening and is electrically connected to the corresponding first isolation structure 140, the mesh-connected first isolation structure 140 can provide cathode signal transmission of the first display area AA1. In some cases, the first electrodes between different light-emitting units in the first display area AA1 can be connected through the second wiring structure 410 according to wiring requirements, and the light-emitting units can realize a common anode signal, and realize the same drive signal to drive multiple light-emitting units in the first display area, thereby reducing the number of wiring in the first display area and improving the transmittance of the first display area.

[0087] Continue to see Figure 3In some embodiments, at least one first wiring structure includes a first wiring structure 311, wherein the first wiring structure 311 connects a plurality of first isolation structures 140. Specifically, the anode layer 130 is disposed between the substrate 110 and the first isolation structure 140, and the anode layer 130 is provided with a plurality of spaced first electrodes 131, and the orthographic projection of the first electrode 131 on the substrate 110 overlaps with the orthographic projection of the pixel opening S1 on the substrate 110, and the first electrode 131 is exposed in the pixel opening S1, and different first electrodes 131 are insulated from each other. The first isolation structures 140 between at least two first electrodes 131 may be connected by the first wiring structure 311, and illustratively, the first isolation structures 140 are spaced from each other, and a spacer region is formed between the first isolation structures 140, so that the first electrodes 131 are insulated from each other. The first wiring structure 311 may be provided in the insulated spacer region between the first electrodes 131, and the first wiring structure 311 is insulated from the first electrode 131. In some embodiments, the spacing area between the first electrodes 131 coincides with the spacing between the first isolation structures 140, so that the first wiring layer 310 is connected to the first isolation structure 140. Exemplarily, the first wiring layer 310 can be arranged in the same layer as the first electrode 131, so as to reduce the number of film layers and reduce the thickness of the display panel. The first wiring layer 310 and the anode layer 130 can also be made of the same material, so that they can be prepared in the same layer, reducing the preparation process steps.

[0088] A light-emitting functional layer is disposed in the pixel opening S1, and the first electrode 131 exposed in the pixel opening S1 is connected to the light-emitting functional layer. A second electrode is disposed on the side of the light-emitting functional layer away from the substrate 110, and the first isolation structure 140 is connected to the second electrode. The first electrode 131, the light-emitting functional layer, and the second electrode form a light-emitting unit. When the power supply modes of the first display area AA1 and the second display area AA2 are the same, for example, when one pixel driving circuit supplies power to one light-emitting unit, the first electrode 131 of one light-emitting unit can be connected to one pixel driving circuit. In some embodiments, in order to further increase the transmittance of the first display area AA1, the first display area AA1 does not have a pixel driving circuit, but the corresponding driving circuit layer is disposed in the second display area AA2, and multiple pixel driving circuits are disposed in the driving circuit layer of the second display area AA2. In the first display area AA1, at least one conductive layer 320 is disposed between the anode layer 130 and the substrate 110, and the first electrode 131 of the light-emitting unit of the first display area AA1 is connected to a pixel driving circuit of the second display area AA2 through at least one conductive layer 320. The pixel driving circuit outputs the corresponding driving current to the connected light-emitting unit through the conductive layer 320. A first planar layer 330 is also provided between the anode layer 130 and at least one conductive layer 320, and the first planar layer 330 can planarize the surface of the conductive layer away from the substrate 110. Exemplarily, the material of the first planar layer 330 can be an organic glue, which can ensure the planarization reliability of the first planar layer 330. A first through hole is provided on the first planar layer 330, and the anode layer 130 and the conductive layer 330 are connected through the first through hole.

[0089] In some embodiments, Figure 4 FIG. 1 is a schematic diagram of a cross-sectional structure of another display panel AA′ provided in an embodiment of the present invention. Figure 4 The display panel may include: two conductive layers 320, the two conductive layers 320 are stacked between the anode layer 130 and the substrate 110; the first electrode 131 is connected to at least one pixel driving circuit of the second display area AA2 through the two conductive layers 320.

The anode layer 130 and the first conductive layer 321 are connected through the first through hole, and the second conductive layer 322 and the first conductive layer 321 are connected through the second through hole. By arranging multiple layers of conductive layers 320, the circuit space is increased to avoid circuit congestion affecting the transmittance of the first display area. In some embodiments, the second through hole can also penetrate the first flat layer 331 and the second flat layer 332, and the anode layer 130 can be directly connected to the second conductive layer 322 through the second through hole.

[0090] In some embodiments, Figure 5 FIG. 1 is a schematic diagram of a cross-sectional structure of another display panel AA′ provided in an embodiment of the present invention. Figure 5 The first routing structure 311 is arranged on a side of the anode layer 130 close to the substrate 110. For example, the first routing structure 311 is arranged on the same layer as the first conductive layer 321 or the second conductive layer 322. In the embodiment of the present invention, taking the first conductive layer 321 as an example, the first routing layer 310 is arranged on the same layer as the first conductive layer 321. The first flat layer 331 is provided with corresponding first vias. The first vias penetrate the first routing layer 310 and the insulating layer between the first isolation structure 140 and the anode layer 130. Different first isolation structures 140 and the first routing layer 310 are connected through the corresponding first vias.

Specifically, in the first display area AA1, the first isolation structures 140 arranged at intervals can be interconnected by the first wiring structures 311 of the first wiring layer 310, thereby realizing regional cathode signal transmission in the first display area.

[0092] Optionally, the first wiring structure 311 connects the plurality of first isolation structures 140 and the second electrode of the light-emitting unit disposed in the second display area AA2, that is, in the first display area AA1, the first wiring structure 311 forms an electrical connection between the first isolation structures 140, and between the first display area AA1 and the second display area AA2, the first wiring structure 311 is used to connect the second electrode of the light-emitting unit of the second display area AA2, so that the cathode signal of the second display area AA2 can be introduced into the first display area AA1, and there is no need to set a line for introducing cathode signal transmission in the first display area AA1, further reducing the number of wirings in the first display area AA1. By connecting the plurality of first isolation structures 140 and the second electrode of the light-emitting unit of the second display area AA2, the cathode signal can be connected to the first display area AA1 from all directions, reducing the influence of line resistance and improving display uniformity.
