Document Type and Number:
WIPO Patent Application WO/2022/188420
Kind Code:
A1
Abstract:
A display module, comprising a display panel (20), a buffer layer (11) and a stress release portion (13). The display panel (20) comprises a main body area (201), a first bending area (202), a second bending area (203) and a back area (204), wherein the main body area (201), the first bending area (202), the second bending area (203) and the back area (204) are sequentially connected; the first bending area (202) is bent towards the back side of the display panel (20) to form a curved surface; and the second bending area (203) is bent towards the back side of the display panel (20), such that part of the back area (204) is bent to the back side of the first bending area (202). The buffer layer (11) is located on the back side of the display panel (20) and comprises a first buffer portion (111) and a second buffer portion (112) which are arranged side by side in a first direction in a plane parallel to the display panel (20), the first buffer portion (111) is located in the main body area (201), the second buffer portion (112) is located in the first bending area (202), and the elastic modulus of the second buffer portion (112) is smaller than that of the first buffer portion (111). The stress release portion (13) is arranged on the back side of the second bending area (203), is connected to the portion of the second bending area (203) close to the first bending area (202), and is configured to absorb and release stress borne by the second bending area (203) of the display panel (20) during bending.
