Abstract

The invention provides a foldable display device, which comprises a shell; the middle frame comprises a middle frame bending device; a display panel including a panel bending region; the face frame device comprises a face frame provided with an opening, a face frame bending device, a face frame sliding device and a face frame elastic device. When the display panel is in a bending state, the middleframe bending device and the face frame bending device form a first cavity, and the panel bending area is bent into the first cavity; when the display panel is in a non-bending state, the surface frame bending device enables the panel bending area to be in a flattening state by supporting the middle frame bending device. According to the invention, the combined action of the face frame bending device, the face frame sliding device and the face frame elastic device, can effectively release the stress when the foldable display device is in a bending state, thereby the display panel can be smoothly bent and rolled, and avoid wrinkles and fracture damage.

Description

technical field [0001] The present invention relates to the display field, in particular to a foldable display device. Background technique [0002] With the development of flexible display panel technology, foldable or rollable display devices have become an extremely important development direction in future display technology. Due to the advantages of thinness, non-fragility, bendability, foldability, and wearability, flexible display panels can be used in bendable and deformable electronic products, such as smart watches, VR head-mounted displays, and vehicle displays. [0003] During the folding or bending process of the display device, a large stress will be generated in the bending area of ​​the flexible display panel. If the stress is not released, the stress will be too concentrated in the bending area, resulting in fracture or wrinkling. Therefore, it is necessary to install appropriate mechanical components inside the display device so that after the flexible dis...
