Problems solved by technology

[0005] When there is a soft material under the flexible cover, with the addition of external force, the flexible cover will deform with the optical adhesive layer, and its surface hardness will decrease significantly, which cannot meet the needs of the display
The main reason is that the optical adhesive layer is a viscoelastic material and has no compression resistance. It is prone to permanent deformation after being subjected to pressure, resulting in fine cracks on the surface of the flexible cover due to subsidence, which reduces the surface hardness of the entire display device.

Abstract

The invention provides a flexible displaying device. The device comprises a flexible displaying panel, an optical glue layer, a flexible cover plate and a crush-resistance layer; the optical glue layer is arranged at the side, close to the flexible cover plate, of the flexible displaying panel; the crush-resistance layer is arranged between the optical glue layer and the flexible cover plate to reduce deformation of the optical glue layer due to pressure. By arranging the crush-resistance layer between the optical glue layer and the flexible cover plate in the flexible displaying device, the deformation of the optical glue layer due to pressure can be reduced, and then the surface hardness of the flexible displaying device is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device. Background technique [0002] With the development of display technology, display devices have higher and higher requirements for color and lightness. AMOLED (Active-matrix organic light emitting diode, active matrix organic light-emitting diode) is gradually entering consumer electronics markets such as mobile devices and televisions. . Organic light-emitting diode (Organic Light-Emitting Diode, OLED) flexible display device has the advantages of thinness, bendability, foldability, impact resistance, etc., and has become the focus of extensive research at present. [0003] The flexible cover replaces the traditional protective glass cover as the outermost layer of the OLED flexible display device, and must have the high hardness, durability and bending resistance of glass at the same time. [0004] At present, the surface hardness of the flexible co...
