Abstract

The invention provides a foldable display device. The display device comprises a front frame, a bottom frame assembly, a display panel and a support plate, and the display panel is arranged between the front frame and the bottom frame assembly; the support plate is arranged between the display panel and the bottom frame assembly, and comprises a bending area and non-bending areas arranged on the two sides of the bending area. A plurality of open holes which are distributed in an array are formed in the bending area; each open hole comprises two curved side walls which are oppositely arranged and respectively consist of at least one section of arc-shaped part, so that the extension performance and the deformation recovery capability of the bending area of the support plate are improved, thestress and the dislocation amount between the support plate and the display panel are dispersed and reduced, the risk of separation of an inner film layer of the foldable display device is reduced, meanwhile, the integrated support plate can provide good support for all parts of the display panel so as to improve the flatness of the foldable display device, and the assembling difficulty of the display panel, the front frame and the bottom frame assembly is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a foldable display device. Background technique [0002] With the development of display technology, consumers have increasingly diversified and personalized demands on display panels. Foldable display devices have advantages such as bendability and portability, and are favored by consumers. [0003] In order to alleviate the problems of waviness and creases caused by repeated folding or unfolding of existing foldable display devices, it is necessary to attach a metal sheet covering the entire surface on the back of the display panel and only cover the non-bending area of ​​the display panel. This will not only increase the difficulty of assembly and production cost, but also cause a step difference in the bending area of ​​the display panel due to the lack of full coverage of the support plate, reducing the flatness of the display device. [0004] To sum up, existing ...
