Abstract

A display device includes: a shell; a flexible display screen, which is accommodated in the shell in a curlable manner; a rotating shaft, which is arranged in the shell and is used for supporting the flexible display screen to be curled and stretched; and a retaining device, which is arranged in the shell, is linked with the rotating shaft and is used for limiting the flexible display screen to move towards a non-target direction. The retaining device comprises a first retaining assembly at least arranged at one end of the rotating shaft, the first retaining assembly comprises a first retaining piece and a second retaining piece, the first retaining piece and the second retaining piece are oppositely arranged, a braking structure is arranged between the first retaining piece and the second retaining piece, and the first retaining piece and the second retaining piece can move towards the opposite direction to form braking or move towards the opposite direction to release braking; and by arranging the retaining device, the retaining pieces in the retaining device are controlled to limit or release the movement of a display panel, so that a flexible display screen is prevented from flowing back in the rolling-out or rolling-in process, and the flexible display screen is protected from being damaged by external force.

Description

technical field [0001] The invention relates to the display field, in particular to a display device. Background technique [0002] With the development of OLED display technology, flexible OLED technology has gradually matured. As a new display technology module, curly OLED display module will be the direction of innovation and development of global panel and module manufacturers in the future. [0003] Generally, a rollable OLED display module is composed of a reel and a flexible display. The flexible display can play images, and a reel is arranged inside the reel. One end of the flexible screen is connected to the reel, and the flexible screen can be rolled into the reel. The rolling and unfolding of the flexible screen is realized by using the first rolling shaft, and the square containing body is used to accommodate the rolled flexible screen. Utilizing the rigidity of the anti-curl strip on the second reel to fix the unfolded flexible screen can achieve a certain anti...
