Abstract

The invention relates to the technical field of display devices, particularly to a rollable display device. The device comprises a shell, a driving mechanism and a flexible bearing film that are disposed in the shell, and a flexible display screen. The flexible bearing film is arranged to rotate under the driving of the driving mechanism; a first end of the flexible display screen is fixed to theflexible bearing film, a second end of the flexible display screen is arranged to extend out of the shell from an opening formed in the shell, and the flexible display screen can be rolled on the flexible bearing film and can be unfolded under the pulling of an external force. According to the rollable display device of the embodiment, the rolling number of turns of the flexible display screen canbe reduced, so that stress-strain accumulation of the flexible display screen can be reduced, the film interlayer extrusion condition of the flexible display screen is relieved, and the flexible display screen is not prone to being damaged.

Description

technical field [0001] The present application relates to the technical field of display devices, in particular to a rollable display device. Background technique [0002] With the advancement of technology and the development of society, flexible display screens have gradually entered the field of vision of consumers. The rollable flexible display screens not only facilitate the lives of consumers, but also bring consumers a new user experience. When some rollable display devices roll up the flexible display, due to the limited diameter of the reel for winding up the flexible display, as the number of winding turns increases, the accumulation of stress and strain will continue to increase, and the film layers of the flexible display will be squeezed. Serious pressure may easily cause display failure. Contents of the invention [0003] An embodiment of the present application provides a rollable display device, including a housing, a drive mechanism and a flexible carryin...
