[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] To release the electrostatic charge on the first electrode lead, embodiments of the present invention provide the following technical solution:

[0040] Figure 1 This is a top view of the first type of light-emitting screen provided according to an embodiment of the present invention, see [link / reference]. Figure 1 The light-emitting screen includes: a substrate 01; multiple light-emitting units 02, each light-emitting unit 02 including a first electrode, a light-emitting device layer, and a stack of second electrodes, the first electrode being located on the surface of the substrate 01; multiple first electrode leads 03 corresponding to and connected to the first electrodes; the multiple first electrode leads 03 include a first preset lead L1, the first preset lead L1 being provided with at least one first sharp corner structure S1; and an anti-static lead 04, the anti-static lead 04 being provided with at least one second sharp corner structure S2, the first sharp corner structure S1 and the second sharp corner structure S2 being arranged opposite to each other for releasing static charge.

[0041] For example, Figure 1 The diagram shows four light-emitting units 02 and four first electrode leads 03, all of which are first preset leads L1.

[0042] In the technical solution provided in this embodiment, the first sharp corner structure S1 of the first preset lead L1 and the second sharp corner structure S2 of the anti-static lead 04 are arranged opposite to each other. Since the sharp corner structure can collect static charge, the first sharp corner structure S1 and the second sharp corner structure S2 can release the static charge of the first electrode lead 03, thereby avoiding damage to the light-emitting screen by the first electrode.

[0043] Optionally, based on the above technical solutions, see [reference needed]. Figure 2 , Figure 2 This is a top view of a second type of light-emitting screen provided according to an embodiment of the present invention. Multiple first electrode leads 03 include second preset leads L2, which are arranged adjacent to first preset leads L1. The second preset leads L2 are provided with at least one third sharp corner structure S3, which is arranged opposite to the first sharp corner structure S1 for releasing static charge. The anti-static lead 04 is reused as the second preset lead L2, and the second sharp corner structure S2 is reused as the third sharp corner structure S3.

[0044] Specifically, the anti-static lead 04 is reused as the second preset lead L2 among multiple first electrode leads 03, simplifying the structure of the light-emitting screen and reducing manufacturing costs. Furthermore, the elimination of the need for a separate anti-static lead 04 allows for a wider first electrode lead 03, which helps reduce its resistance. The third sharp-angle structure S3, positioned opposite to the first sharp-angle structure S1, is used to release electrostatic charges, effectively dissipating the electrostatic charge from the first electrode lead 03 and preventing damage to the light-emitting screen from the first electrode.

[0045] Optionally, based on the above technical solutions, see [reference needed]. Figure 1 It also includes a first insulating layer 05, and a first preset lead L1 and an antistatic lead 04 located on the same surface of the first insulating layer 05.

[0046] See Figure 2 When the antistatic lead 04 is reused as the second preset lead L2, the second preset lead L2 and the first preset lead L1 are located on the same surface of the first insulating layer 05.

[0047] The above technical solution can release the electrostatic charge on the first electrode lead 03 located in the first insulating layer 05, thereby preventing the first electrode from damaging the light-emitting screen.

[0048] Optionally, based on the above technical solutions, see [reference needed]. Figure 3 and Figure 4 , Figure 3 This is a top view of the third type of light-emitting screen provided according to an embodiment of the present invention. Figure 4 yes Figure 3A schematic cross-sectional view of the first electrode lead along the A1-A2 direction is shown. The light-emitting screen also includes a second insulating layer 06, with the first preset lead L1 and the anti-static lead 04 located on different surfaces of the second insulating layer 06. Further, see... Figure 4 The second insulating layer 06 includes a first surface and a second surface disposed opposite to the first surface. The first preset lead L1 is located on the first surface, and the antistatic lead 04 is located on the second surface.

[0049] The above technical solution can release the electrostatic charge on the first electrode lead 03 located in the second insulating layer 06, thereby preventing the first electrode from damaging the light-emitting screen.

[0050] See Figure 5 and Figure 6 , Figure 5 This is a top view of the fourth type of light-emitting screen provided according to an embodiment of the present invention. Figure 6 yes Figure 5 A cross-sectional view of the first electrode lead in the A1-A2 direction. When the anti-static lead 04 is reused as the second preset lead L2, the light-emitting screen also includes a fourth insulating layer 07. Multiple first electrode leads include a third preset lead L3. The first preset lead L1 and the third preset lead L3 are located on different surfaces of the fourth insulating layer 07. The first preset lead L1 is provided with a fourth sharp corner structure S4, and the third preset lead L3 is provided with a fifth sharp corner structure S5. The fourth sharp corner structure S4 and the fifth sharp corner structure S5 are arranged opposite to each other to release static charge.

[0051] The above technical solution can release the electrostatic charge on the first electrode lead 03 (first preset lead L1 and third preset lead L3) located on the two opposite surfaces of the fourth insulating layer 07, thereby preventing the first electrode from damaging the light-emitting screen.

[0052] Optionally, based on the above technical solutions, see [reference needed]. Figure 7 , Figure 7 This is a top view of the fifth type of light-emitting screen provided according to an embodiment of the present invention. The light-emitting screen further includes a third insulating layer 08, which is located between the first preset lead L1 and the anti-static lead 04.

[0053] The above technical solution provides a third insulating layer 08 between the first preset lead L1 and the anti-static lead 04. While the first sharp corner structure S1 and the second sharp corner structure S2 release the static charge of the first preset lead L1, it can prevent short circuits in the first preset lead L1 and the anti-static lead 04 except for the portions of the first sharp corner structure S1 and the second sharp corner structure S2.

[0054] See Figure 8 , Figure 8This is a top view of the sixth type of light-emitting screen provided according to an embodiment of the present invention. When the anti-static lead 04 is reused as the second preset lead L2, the third insulating layer 08 is located between the second preset lead L2 and the first preset lead L1.

[0055] The above technical solution provides a third insulating layer 08 between the first preset lead L1 and the second preset lead L2. While the first sharp corner structure S1 and the third sharp corner structure S3 release electrostatic charges, it can prevent short circuits from occurring in the portions of the first preset lead L1 and the second preset lead L2 excluding the first sharp corner structure S1 and the third sharp corner structure S3.

[0056] Optionally, based on the above technical solutions, see [reference needed]. Figure 9 , Figure 9 yes Figure 7 A top view of the third insulating layer having a first through hole. The third insulating layer 08 has a first through hole T1, a first sharp corner structure S1 located in the first through hole T1, and a second sharp corner structure S2 located in the first through hole T1.

[0057] The above technical solution provides a first through hole T1 in the third insulating layer 08, which exposes the first sharp corner structure S1 and the second sharp corner structure S2, thereby helping to improve the ability of the first sharp corner structure S1 and the second sharp corner structure S2 to release electrostatic charges.

[0058] See Figure 10 , Figure 10 yes Figure 8 A top view of the third insulating layer with a first through hole. When the anti-static lead 04 is reused as the second preset lead L2, the third insulating layer 08 is provided with a first through hole T1, the first sharp corner structure S1 is located in the first through hole T1, and the third sharp corner structure S3 is located in the first through hole T1.

[0059] The above technical solution provides a first through hole T1 in the third insulating layer 08, which exposes the first sharp corner structure S1 and the third sharp corner structure S3, thereby helping to improve the ability of the first sharp corner structure S1 and the third sharp corner structure S3 to release electrostatic charges.

[0061] In the above technical solution, the second insulating layer 06 is provided with a second through hole T2, which exposes the first sharp corner structure S1 and the second sharp corner structure S2, which helps to improve the ability of the first sharp corner structure S1 and the second sharp corner structure S2 to release electrostatic charge.

[0062] See Figure 12 , Figure 12 yes Figure 6 The schematic diagram shows that the second insulating layer is provided with a second through hole. When the anti-static lead 04 is reused as the second preset lead L2, the fourth insulating layer 07 is provided with a second through hole T2, the fourth sharp corner structure S4 is located in the second through hole T2, and the fifth sharp corner structure S5 is located in the second through hole T2.

[0063] The above technical solution provides a second through hole T2 in the fourth insulating layer 07, which exposes the fourth sharp corner structure S4 and the fifth sharp corner structure S5, thus helping to improve the ability of the fourth sharp corner structure S4 and the fifth sharp corner structure S5 to release electrostatic charge.
