Abstract

The invention discloses a rollable display device, which comprises a flexible display panel, a storage shell and a flexible covered edge, wherein the flexible display panel comprises two correspondingshort side surfaces and two corresponding long side surfaces; the storage shell is provided with an opening along one short side surface of the flexible display panel, the other short side surface ofthe flexible display panel is fixedly connected to the interior of the storage shell, and the flexible display panel is relatively rolled in or rolled out of the storage shell through the opening; the flexible covered edge is arranged on at least one long side surface of the flexible display panel; and at least one universal ball module is arranged in the flexible covered edge. According to the invention, the flexible covered edge and the universal ball module are additionally arranged, so that the friction force generated in the process that the flexible display panel is rolled in and out ofthe storage shell can be greatly reduced, the technical problems of jamming, unsmooth movement and the like in the rolling-in and rolling-out process are solved, then the product quality of the rollable flexible display device is improved, and the service life of the rollable flexible display device is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a rollable flexible display device. Background technique [0002] Organic Light-Emitting Diode (OLED) displays are currently used in flexible display products such as foldable mobile phones, smart watches, and vehicle displays due to their advantages of thinness, flexibility, foldability, and curling. The concept of rollable products with better bending performance has also appeared in major exhibitions, becoming a major technological innovation after folding. [0003] In order to achieve the overall free curling, flexible materials must be used for each layer of the OLED module. At the same time, how to improve the curling smoothness of the module in the mechanism has become an important technical problem for rollable products. Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a rollable flexible display device in the prior art. Wherein, the edge o...
