Title:
DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/178685
Kind Code:
A1
Abstract:
A display panel and a display apparatus, which relate to the technical field of displays. The display panel comprises: a light-emitting substrate (100), which comprises a plurality of light-emitting devices (3) which are arranged in an array; a first light extraction layer (7), which is at least located on a light emission side of some of the light-emitting devices (3), and comprises a plurality of prisms (71) which extend in a first direction (OB) and are arranged in a second direction (OA); and a second light extraction layer (9), which is located on the light emission side of the light-emitting devices (3) and is located on the side of the first light extraction layer (7) that is away from the light-emitting substrate (100), and comprises a plurality of convex lenses (91) that are arranged in an array, wherein an orthographic projection of the first light extraction layer (7) on the light-emitting substrate (100) is located within an orthographic projection of the second light extraction layer (9) on the light-emitting substrate (100), and the maximum size (W) of the prisms (71) in the second direction (OA) is less than or equal to the maximum size (D) of the convex lenses (91) in the second direction (OA), the first direction (OB) intersecting with the second direction (OA). The display panel can solve chromatic aberration problems in a large angle of view, and can improve light emission intensity of the display panel in a positive angle of view.
