Abstract

The invention discloses a flexible display device. The flexible display device comprises a flexible display screen and a plurality of first reels, and the flexible display screen comprises a pluralityof sets of flexible film layers corresponding to the multiple first reels one to one; and one end of each set of flexible film layer is connected with the first reel corresponding to the flexible film layer, so that when the flexible display screen is in a curled state, each set of flexible film layer is curled on the first reel corresponding to the set of flexible film layer, and thus the curling capacity of the flexible display screen is improved.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a flexible display device. Background technique [0002] With the development of flexible display technology, OLED has shown its great potential in flexible display. From fixed flexible displays to foldable displays, displays are both large and portable. In order to enable the display screen to further meet the requirement of convenient storage or portability when not in use, more and more people pay attention to the rollable flexible display screen. [0003] However, due to the need to set polarizers, touch screens, protective film materials and other film layers in the OLED display screen, the thickness of the display screen is relatively large, and the curl lengths of each film layer are different, and the film layers are fixedly connected by adhesives, so that all The stress of the film layer is continuously accumulated during the curling process, resulting i...
