Patent number: 11567352Abstract: The present application discloses a display module, a preparation method thereof, and a display apparatus. In a non-display region of the display panel, the display panel and the optical adhesive have a first open pore and a second open pore penetrating through their thickness, respectively; and an orthographic projection of the first open pore falls in an orthographic projection of the second open pore on the cover plate. A light shading part in the light shading region has a third open pore surrounding the light transmitting region; and the light shading part includes a photochromic material in a light shading state, and an orthographic projection of the light shading part on the cover plate at least covers a region, which does not overlap with the orthographic projection of the first open pore on the cover plate, of the orthographic projection of the second open pore on the cover plate.Type: GrantFiled: September 27, 2021Date of Patent: January 31, 2023Assignees: Chengdu BOE Optoelectronics Technology Co., Ltd., BOE Technology Group Co., Ltd,.Inventors: Chuandong Liao, Liqiang Chen, Mengyuan Pang, Yaming Wang, Yanxin Wang, Dongdong Zhao
