[0060] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0061] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0062] With the continuous development of full-screen technology, under display camera (UDC) technology has been proposed. Compared with the existing "bangs" screen, blind hole screen, etc., the display screen using under-screen camera technology can also display the camera area, thus realizing a true full-screen.

[0063] In the related technology, the under-screen camera (UDC) technology refers to the technology of setting the camera between the display screen and the shell of the display device. The display panel using the under-screen camera technology usually has two areas, one is the under-screen camera area, which can also be called the secondary screen area or the first display area, and the other is the normal display area, which can also be called the main screen area or the second display area. Among them, the transmittance of the first display area is greater than the transmittance of the second display area. This can be achieved by reducing the number of sub-pixels in the first display area and reducing the size of the sub-pixels. For example, in the UDC area, the light-emitting area of ​​the pixel is reduced, and multiple sub-pixels are connected together using an ITO film layer for driving, so as to improve the transmittance of the UDC area; or the UDC area usually uses an external pixel circuit to realize the driving of the pixel, such as Figure 1 As shown, however, in the prior art, the ITO film layer 2 is arranged at the same layer as the anode Anode layer 1 in the sub-pixel, which results in the ITO film layer 2 needing to avoid the anode Anode layer 1 for winding when connecting the sub-pixels of multiple pixels together. However, when preparing the display function layer of the display panel in the present application, the light-emitting elements with different output light colors are independently manufactured, and the film layer (evaporated film layer such as the light-emitting function layer, etc.) in each light-emitting element is evaporated on the entire surface of the display panel during evaporation, resulting in the anode Anode layer of the light-emitting element being larger. At this time, the ITO film layer 2 has a larger range for winding around the anode Anode layer 1, so it is difficult to achieve a high pixel density (Pixels Per Inch, PPI) design, which affects the development of UDC technology. Therefore, how to achieve a high pixel density (PPI) design for UDC products has become a problem that needs to be solved urgently.

[0064] Based on the above reasons, a first aspect of the present application provides a display panel, which realizes a high pixel density (PPI) design of a UDC product.

[0065] Next, combine Figure 2-Figure 10To describe the display panel provided in an embodiment of the present application, 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 light transmittance of the first display area AA1 is greater than the light transmittance of the second display area AA2. The specific shape, size, relative position relationship, etc. of the first display area AA1 and the second display area AA2 are not limited. For example, the second display area AA2 can be located on at least one side of the first display area AA1 in a certain direction, or can be arranged around the second display area AA2 on multiple sides of the periphery of the first display area AA1. In some embodiments, the display panel may also include a non-display area NAA, which is arranged around the first display area AA1 and the second display area AA2.

[0066] It can be understood that the first display area AA1 is the under display camera (UDC) area of ​​the display panel, which can also be called the secondary screen area; the second display area AA2 is the normal display area of ​​the display panel, which can also be called the main display area.

(The composition, preparation, etc. of the first light-emitting element 310, the first light-emitting element 320, and the isolation structure 400 mentioned below are further described in patents PCT / CN2023 / 134518, CN117979755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, CN117500332A, CN117580403A, CN116669477B, and CN116936581B for reference.)

[0068] Exemplarily, in the present disclosure, the substrate 100 mainly plays a supporting and bearing role. The substrate 100 can be a hard substrate 100 made of materials such as glass or plastic, or a flexible substrate 100 made of materials such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP).

[0069] refer to Figure 4-Figure 6 In a specific embodiment, multiple second lines 21 extend from the second display area AA2 to the first display area AA1, and the orthographic projection of the second line 21 on the substrate 100 at least partially overlaps with the orthographic projection of the light-transmitting opening on the substrate 10; further, at least two first light-emitting elements 310 with the same luminous color are electrically connected to the second line 21 through the first line 11, and the orthographic projection of the first line 11 on the substrate 10 at least partially overlaps with the orthographic projection of the light-transmitting opening on the substrate 10.

[0070] In a specific embodiment, the first wiring layer 10 and the second wiring layer 20 are arranged in different layers, such as Figure 4 and Figure 5 As shown, on the one hand, the second wiring layer 20 is located on the side of the first wiring layer 10 close to the substrate 100. Since the first wiring layer 10 and the first metal layer 30 are arranged in the same layer, that is, the second wiring layer 20 is located on the side of the first metal layer 30 close to the substrate 100, and is located on the side of the first driving unit 210 away from the substrate 100, the anode Anode signal of the first display area AA1 is connected to the first wiring 11 through the first light-emitting element 310, and then connected to the second wiring 21 by the first wiring 11, and finally connected to the first metal line and the first driving unit 210 by the second wiring 21, so that the first display area AA1 realizes the conduction of the anode Anode signal. In this embodiment, by arranging the second wiring layer 20 between the first driving unit 210 and the first metal layer 30, and arranging the first wiring layer 10 and the first metal 230 in the same layer, it is beneficial to increase the wiring space of the first wiring layer 10, and then it is beneficial to realize the high pixel density design of the UDC product, such as Figure 6As shown, on the other hand, the second wiring layer 20 is located on the side of the first wiring layer 10 away from the substrate 100; since the first wiring layer 10 and the first metal layer 30 are arranged in the same layer, that is, the second wiring layer 20 is located on the side of the first metal layer 30 away from the substrate 100, the anode Anode signal of the first display area AA1 is connected to the second wiring 21 through the first light-emitting element 310, the first wiring 11 is electrically connected to two adjacent first light-emitting elements 310, and is electrically connected to the second wiring 21, and finally the second wiring 21 connects the first metal wire 31 and the first driving unit 210, so as to realize the conduction of the anode Anode signal between the first driving unit 210 and the first light-emitting 310 element. Such a design is not only conducive to increasing the wiring space of the first wiring layer 10, and then conducive to realizing the high pixel density design of the UDC product, but also conducive to the flatness of the display functional layer, which can be specifically manifested as the flatness of the first light-emitting element 310.

The second driving unit 220 of the first sub-display area AA21 is electrically connected to the second light-emitting element 320 via the first metal wire 31 and the second wiring 21; that is, the anode Anode signal of the second light-emitting element 220 of the first sub-display area AA21 is transmitted to the second driving unit 220 through the first metal wire 31 and the second wiring 21, so as to realize the conduction of the anode Anode signal between the second driving unit 220 and the second light-emitting element 320 of the first sub-display area AA21.
