Document Type and Number:
WIPO Patent Application WO/2023/220984
Kind Code:
A1
Abstract:
A display panel and a display apparatus. The display panel comprises: a display substrate (21), which comprises a light-emitting area (A), and a non-light-emitting area (B), which surrounds the light-emitting area (A), wherein the light-emitting area (A) comprises a first light-emitting area (A1), which is located in a first display area, and a second light-emitting area (A2), which is located in a second display area; a functional film layer (22), which is arranged on a light-emitting side of the display substrate (21); a low refractive layer (23), which is arranged on the side of the functional film layer (22) that is away from the display substrate (21); and a first high refractive layer (24), which is arranged on the side of the low refractive layer (23) that is away from the display substrate (21), wherein the refractive index of the first high refractive layer (24) is greater than the refractive index of the low refractive layer (23); the side face of the low refractive layer (23) that faces the first light-emitting area (A1) is in contact with the first high refractive layer (24) to form a first total reflection interface (s1), and the side face of the low refractive layer (23) that faces the second light-emitting area (A2) is in contact with the first high refractive layer (24) to form a second total reflection interface (s2); and in the normal direction of the display substrate (21), the minimum distance (d1) between the first light-emitting area (A1) and the first total reflection interface (s1) is different from the minimum distance (d2) between the second light-emitting area (A2) and the second total reflection interface (s2).
