[0058] The substrate of flexible OLED is made of flexible organic materials. Currently, the most widely used one is polyimide (PI), which has a thickness of tens of microns. The thinner substrate material makes the flexible OLED products display poorly due to static electricity when subjected to strict electrostatic tests or when certain terminals are subjected to strict usage conditions.

[0059] Please refer to Figure 1 As shown, a related display panel 100 includes a substrate 10, the substrate 10 includes a display area 101 and a non-display area 102, and the non-display area 102 is arranged around the display area 101. The inventors have found through research that in actual use or testing scenarios, external static electricity generally enters the non-display area 102 from the outside of the display panel 100, and then extends from the non-display area 102 to the display area 101. The static electricity entering the display panel 100 will cause the thin film transistor (TFT) characteristics to fluctuate, resulting in display abnormality or functional failure.

[0060] Based on this, the present application provides a display panel and a display device solution to solve the above problems.

[0061] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, a display panel 100 provided in an embodiment of the present application is provided. The display panel 100 includes a substrate 10, a first electrostatic shielding line 11 and an electrostatic protection structure 13, wherein the substrate 10 includes a display area 101 and a non-display area 102, the non-display area 102 is arranged around the display area 101, the first electrostatic shielding line 11 is located on one side of the substrate 10 and in the non-display area 102, and the first electrostatic shielding line 11 is arranged in a closed manner around the display area 101. The electrostatic protection structure 13 and the first electrostatic shielding line 11 are located on the same side of the substrate 10 and in the non-display area 102, and the electrostatic protection structure 13 is electrically connected to the first electrostatic shielding line 11, and is used to absorb static electricity on the first electrostatic shielding line 11.

[0062] The display panel 100 provided in the embodiment of the present application sets a closed first electrostatic shielding line 11 in the non-display area 102, so that static electricity is conducted on the first electrostatic shielding line 11, thereby preventing static electricity from being transmitted to the display area 101. The static electricity can be transmitted to the electrostatic protection structure 13 electrically connected to the first electrostatic shielding line 11 and absorbed by the luminescent material in the electrostatic protection structure 13, thereby reducing the risk of static electricity entering the display area 101 and causing poor display, thereby improving the performance of the display panel.

[0063] Reference Figure 2 , Figure 3As shown, in one embodiment, the second electrostatic shielding line 12 and the first electrostatic shielding line 11 are located on the same side of the substrate 10 and in the non-display area 102, the second electrostatic shielding line 12 is closed around the first electrostatic shielding line 11, and the spacing between the first electrostatic shielding line 11 and the second electrostatic shielding line 12 is not equal.

[0064] Preferably, the first electrostatic shielding line 11 and the second electrostatic shielding line 12 are arranged at intervals. The first electrostatic shielding line 11 and the second electrostatic shielding line 12 are located on a side of the electrostatic protection structure 13 close to the substrate 10 .

[0065] The second electrostatic shielding wire 12 is used to absorb external static electricity and release part of the absorbed external static electricity to the first electrostatic shielding wire 11. Specifically, when the external static electricity is strong, it will break through the second electrostatic shielding wire 12 and the first electrostatic shielding wire 11 arranged inside and outside, so that the second electrostatic shielding wire 12 is connected to the first electrostatic shielding wire 11, and then the luminescent material in the electrostatic protection structure 13 finally absorbs the static electricity.

[0066] Specifically, the first electrostatic shielding line 11 and the second electrostatic shielding line 12 are in a closed shape, such as a closed ellipse, circle or polygon, or other shapes known to those skilled in the art, and the polygon may be a triangle, a quadrilateral, a pentagon, etc. The outline of the display area 101 is a rectangle, and the shapes of the first electrostatic shielding line 11 and the second electrostatic shielding line 12 are preferably rectangular.

[0067] Reference Figure 2 , Figure 3 As shown, in one embodiment, the second electrostatic shielding line 12 includes a first tip portion 121 protruding toward a side close to the display area 101, and the minimum distance between the first electrostatic shielding line 11 and the second electrostatic shielding line 12 is located at the first tip portion 121, so that part of the external static electricity absorbed by the second electrostatic shielding line 12 is released to the first electrostatic shielding line 11 through the first tip portion 121.

[0068] With the side where the display area 101 is located as the inner side, and the side away from the display area 101 as the outer side, in this embodiment, by setting an inwardly convex first tip portion 121, when external static electricity is transmitted to the second electrostatic shielding line 12, some static electricity will accumulate at the tip of the first tip portion 121, thereby gathering the static electricity on the second electrostatic shielding line 12. Furthermore, the minimum spacing between the second electrostatic shielding line 12 and the first electrostatic shielding line 11 is the position of the first tip portion 121. When the static electricity on the second electrostatic shielding line 12 is strong, the first tip portion 121 discharges. In other words, part of the static electricity on the second electrostatic shielding line 12 is released to the first electrostatic shielding line 11 through the first tip portion 121, thereby increasing the release speed of the static electricity.

[0069] Specifically, the side of the first electrostatic shielding line 11 is arranged in a straight line, and the side of the second electrostatic shielding line 12 is arranged in a non-straight line, specifically in a sawtooth shape.

[0070] Preferably, the second electrostatic shielding wire 12 includes a plurality of first tip portions 121. The plurality of first tip portions 121 disposed at intervals on the second electrostatic shielding wire 12 improves the ability of the tip of the second electrostatic shielding wire 12 to accumulate and discharge static electricity.

[0071] Specifically, the electrostatic protection structures 13 correspond to the first tip portions 121 in number and position.

[0072] Preferably, the orthographic projection of the electrostatic protection structure 13 on the substrate 10 overlaps with the orthographic projection of the first tip portion 121 on the substrate 10. The electrostatic protection structure 13 covers at least part of the first tip portion 121, and the electrostatic protection structure 13 is distributed at the location of the first tip portion 121, so that the static electricity released from the first tip portion 121 to the first electrostatic shielding line 11 is guided in a targeted manner and absorbed in time by the electrostatic protection structure 13 at the corresponding position.

[0073] Continue to refer to Figure 3 As shown, in one embodiment, the second electrostatic shielding line 12 includes a second tip portion 122 protruding toward a side away from the display area 101, and the second tip portion 122 is used to absorb external static electricity. The second electrostatic shielding line 12 mainly absorbs external static electricity through the protruding second tip portion 122.

[0074] Preferably, the second electrostatic shielding wire 12 includes a plurality of second tip portions 122. That is, the second electrostatic shielding wire 12 includes a plurality of inwardly convex sawtooth-shaped first tip portions 121 and a plurality of outwardly convex sawtooth-shaped second tip portions 122, which helps to improve the electrostatic handling capability.

[0075] Preferably, the first tip portion 121 and the second tip portion 122 are arranged alternately. The orthographic projection of the electrostatic protection structure 13 on the substrate 10 overlaps with the orthographic projection of the second tip portion 122 on the substrate 10. The alternating arrangement of the first tip portion 121 and the second tip portion 122 makes the distribution of static electricity on the second electrostatic shielding line 12 more uniform.

Since the second light-emitting composite layer 131 and the first light-emitting composite layer 201 are arranged on the same layer, and the second metal layer 132 and the first metal layer 202 are arranged on the same layer, the electrostatic protection structure 13 located in the non-display area 102 is similar to the normal pixel structure located in the display area 101.
