[0058] Virtual reality (VR) displays utilize computer graphics systems and various display and control interface devices to provide an immersive experience within a computer-generated, interactive three-dimensional environment. VR displays work by displaying images for each eye separately. This differentiated information creates a three-dimensional perception in the human mind.

[0059] Current VR display devices use lenses to magnify the image and focus it on the human eye, which has the effect of magnifying a small screen. Figure 1 As shown, the user's eyeballs are usually set corresponding to the central area of ​​the display panel, and the light output of the light-emitting unit 300' in the central area is usually not blocked, but the light output of the light-emitting unit in the edge area may be blocked by the isolation structure 200', which leads to inconsistent light output in the central area and the edge area, resulting in inconsistent viewing angles in the middle and edges of the screen. The human eye perceives inconsistent brightness and color deviation in the middle and edges of the screen, affecting the performance of the VR display device.

[0060] In order to solve the above technical problems, this application is proposed. Figures 2 to 6 The display panel and the display device according to the embodiment of the present application are described in detail.

[0061] Please also refer to Figures 2 to 4 , Figure 2 A top view of a display panel provided in an embodiment of the present application is shown. Figure 3 In one example Figure 2 The cross-sectional view at AA in the middle, Figure 4 This is a schematic structural diagram of a display panel provided by an embodiment of the present application in use.

[0062] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present application provides a display panel 10 , which includes a substrate 100 , an isolation structure 200 and a light-emitting layer 300 .

[0063] The display panel comprises a first area ZA and a second area BA surrounding at least part of the first area ZA, and the display panel comprises: a substrate 100; an isolation structure 200 arranged on one side of the substrate 100, the isolation structure 200 encloses a first isolation opening 210 located in the first area ZA and a second isolation opening 220 located in the second area BA; and a light-emitting layer 300 comprising light-emitting units, the light-emitting units comprising first light-emitting units 310 located in the first isolation opening 210 and second light-emitting units 320 located in the second isolation opening 220, wherein the isolation structure 200 comprises a first isolation segment 201 and a second isolation segment 202, the first isolation segment 201 encloses the first isolation opening 210, the second isolation segment 202 encloses the second isolation opening 220 and is located on a side of the second isolation opening 220 facing the first area ZA, the minimum distance from the first light-emitting unit 310 to the first isolation segment 201 corresponding to the first isolation opening 210 where the first light-emitting unit 310 is located is a first distance d1, the minimum distance from the second light-emitting unit 320 to the second isolation segment 202 corresponding to the second isolation opening 220 where the second light-emitting unit 320 is located is a second distance d2, and the first distance d1 and the second distance d2 satisfy: d1 < d2.

[0064] In the display panel provided in the embodiments of the present application, the display panel comprises a substrate 100, an isolation structure 200 and a light-emitting layer 300, the isolation structure 200 encloses an isolation opening, and the light-emitting units are located in the isolation opening to realize light-emitting display of the display panel. The isolation structure 200 comprises a first isolation opening 210 and a second isolation opening 220, and the second isolation opening 220 is located in the second area BA, i.e., the second isolation opening 220 is located in the edge display area of the display panel. The first light-emitting units 310 are arranged in the first isolation opening 210, and the first light-emitting units 310 are arranged close to the center of the display panel. The second light-emitting units 320 are arranged in the second isolation opening 220, and the second light-emitting units 320 are arranged close to the edge of the display panel. The first distance d1 and the second distance d2 satisfy: d1 < d2, i.e., the distance from the second light-emitting unit 320 to the second isolation segment 202 is farther, which can reduce the shielding effect of the second isolation segment 202, so that the small-angle light emitted by the second light-emitting unit 320 can be emitted from the second isolation opening 220. The light emission amounts of the first area ZA and the second area BA tend to be consistent, thereby improving the display effect of the display panel and improving the use performance of the display panel.

[0065] When the display panel is used in a virtual reality display device, the eyeball center of the user is usually arranged corresponding to the central area of the display panel, the light emitted by the first light-emitting units 310 is less shielded by the isolation structure 200, and the light emitted by the second light-emitting units 320 may be shielded by the second isolation segment 202, Figure 4 The light emission direction of the light shielded by the second light-emitting unit 320 before the position adjustment is shown by a dashed line. Figure 4The second light-emitting unit 320 emits light in the direction indicated by the solid arrow in the embodiment of the application. By increasing the second distance d2 between the second isolation segment 202 and the second light-emitting unit 320, the blocking effect of the second isolation segment 202 can be reduced, so that the small-angle light emitted by the second light-emitting unit 320 can be emitted by the second isolation opening 220. The amount of light emitted by the first zone ZA and the second zone BA tends to be consistent, thereby improving the display effect of the display panel and improving the use performance of the display panel.

[0066] Optionally, in the first zone ZA, the distance between the first light-emitting unit 310 in a certain first isolation opening 210 and the first isolation segment 201 surrounding the first isolation opening 210 is a first distance d1. The first distance can be the distance from the first light-emitting unit 310 to the first isolation segment 201 at any position in the circumferential direction thereof. Optionally, the first distance can be the minimum distance from the geometric center of the orthographic projection of the first light-emitting unit 310 to the first isolation segment 201 at any position in the circumferential direction thereof.

[0067] Optionally, when the first light-emitting unit 310 and the second light-emitting unit 320 are adjacent, the isolation segment located between the first light-emitting unit 310 and the second light-emitting unit 320 can be used as the first isolation segment 201 or the second isolation segment 202.

[0068] Optionally, in the second zone BA, the distance between the second light-emitting unit 320 in a certain second isolation opening 220 and the first isolation segment 201 located on the side of the first zone ZA is a second distance d2. Optionally, the minimum distance from the geometric center of the orthographic projection of the second light-emitting unit 320 to the second isolation segment 202 located on the side of the first zone ZA is a second distance d2.

[0069] In some optional embodiments, a plurality of second isolation openings 220 are distributed at intervals in the second zone BA, and each second isolation opening 220 is provided with a second light-emitting unit 320. Among at least two adjacent second light-emitting units 320, the second distance d2 corresponding to the second light-emitting unit 320 located closer to the first zone ZA is smaller than the second distance d2 corresponding to the second light-emitting unit 320 located farther away from the first zone ZA.

[0070] The second distance d2 corresponding to the second light-emitting unit 320 is the second distance d2 between the second light-emitting unit 320 and the second isolation segment located on the side of the first zone ZA.

[0071] In these optional embodiments, a plurality of second isolation openings 220 are arranged in the second area BA, and each of the second isolation openings 220 is arranged with a second light emitting unit 320. Among two adjacent second light emitting units 320, the second distance d2 of the second light emitting unit 320 close to the first area ZA is smaller than the second distance d2 of the second light emitting unit 320 away from the first area ZA, that is, the second distance d2 of each second light emitting unit 320 gradually increases in the direction away from the first area ZA, which can gradually reduce the shielding effect of the second isolation segment 202 on the second light emitting unit 320, and further improve the display uniformity.

[0072] Optionally, the comparison of the second distance d2 of the two adjacent second light emitting units 320 can be the comparison of the second distance d2 of the second light emitting units 320 of different colors.

[0073] Alternatively, in other optional embodiments, among at least two adjacent second light emitting units 320 of the same color, the second distance d2 of the second light emitting unit 320 close to the first area ZA is smaller than the second distance d2 of the second light emitting unit 320 away from the first area ZA.

[0074] In these optional embodiments, the comparison of the second distance d2 of the two adjacent second light emitting units 320 is the comparison of the second distance d2 of the second light emitting units 320 of the same light emitting color, the emitted light of the second light emitting units 320 of the same light emitting color has the same wavelength, and the second distance d2 of the second light emitting units 320 of the same color gradually increases in the direction away from the first area ZA, which can better ensure the light emitting effect.

[0075] In some optional embodiments, among at least two adjacent second light emitting units 320 of the same color, the distance difference between the second distance d2 of the second light emitting unit 320 close to the first area ZA and the second distance d2 of the second light emitting unit 320 away from the first area ZA is d c The distance difference d c is different for the second light emitting units 320 of different colors.

[0076] In these optional embodiments, the distance difference d is different for the second light emitting units 320 of different colors, that is, the second distance d2 of the second light emitting units 320 of different colors changes with different gradients in the direction away from the first area ZA, so as to better adapt to the wavelengths of the emitted light of the second light emitting units 320 of different colors, and better ensure the light emitting effect.

[0106] Optionally, the second electrode 303 and the third sub-layer are electrically connected to each other, which can increase the distribution area of the conductive material and reduce the voltage drop of the second electrode 303.

[0107] Optionally, the display panel further includes a pixel definition layer 400.

The pixel opening 420 and the isolation opening are in communication, and the light emitting structure is located in the pixel opening 420. That is, the light emitting material located in the pixel opening 420 forms the light emitting structure 302.

The first height h1 and the second height h2 of the second isolation segment 202 satisfy the following: h1>h2. That is, the height of the second isolation segment 202, where the second light-emitting unit 320 is located toward the first zone ZA, is lower, which can reduce the shielding effect of the second isolation segment 202, allowing the small-angle light emitted by the second light-emitting unit 320 to be emitted from the second isolation opening 220. This makes the light emission amounts of the first zone ZA and the second zone BA tend to be consistent, thereby improving the display effect of the display panel and enhancing the performance of the display panel.

[0111] When the display panel is used in a display device such as virtual reality, the eyeball center of the user usually corresponds to the center region setting of the display panel, and the light emitted by the first light emitting unit 310 is less blocked by the isolation structure 200, while the light emitted by the second light emitting unit 320 can be blocked by the second isolation segment 202. By reducing the height of the second isolation segment 202, the blocking effect of the second isolation segment 202 can be reduced, so that the small-angle light emitted by the second light emitting unit 320 can be emitted by the second isolation opening 220. The light emission amounts of the first region ZA and the second region BA are consistent, thereby improving the display effect of the display panel and improving the use performance of the display panel.

[0114] In some optional embodiments, among at least two adjacent second isolation openings 220 of the same color second light emitting unit 320, the second height h2 of the second isolation segment 202 corresponding to the second isolation opening 220 disposed close to the first region ZA is greater than the second height h2 of the second isolation segment 202 corresponding to the second isolation opening 220 disposed away from the first region ZA;
