Foldable cover plate assembly, manufacturing method, foldable display device and manufacturing method

Abstract

The embodiment of the invention provides a foldable cover plate assembly and a manufacturing method thereof, and a foldable display device and a manufacturing method thereof, relates to the technical field of display, and can enable a cover plate to have relatively good bending performance and anti-scraping and anti-pressing performance, and can enable the cover plate to realize bidirectional bending. The foldable cover plate assembly comprises a cover plate, the cover plate comprises a folding portion and a non-folding portion, the folding portion comprises an outer bending portion and an inner bending portion, the outer bending portion is recessed from a first side of the cover plate to a second side of the cover plate, the inner bending portion is recessed from the second side to the first side, the thickness of the folding portion is smaller than that of the non-folding portion, and the thickness of the folding portion is smaller than that of the non-folding portion. The first side and the second side are opposite sides of the cover plate; moreover, in the direction perpendicular to the plane where the cover plate is located, the outer bent part and the inner bent part are arranged in a staggered mode, the outer bent part covers the outer axis of the cover plate, and the inner bent part covers the inner axis of the cover plate.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular to a foldable cover assembly and a manufacturing method, a foldable display device and a manufacturing method. Background technique [0002] With the continuous development of flexible display technology, the structures of display devices are becoming more and more diverse. Among them, foldable display devices are favored by consumers due to their advantages of bendability and portability. [0003] The foldable display device includes a foldable display module and a foldable cover assembly covering the foldable display module. In the prior art, the cover in the foldable cover assembly usually adopts a polyimide cover (Cover Polyimide , CPI) or ultra-thin glass (Ultra Thin Glass, UTG) cover plate structure, however, these two cover plates have obvious defects in their own performance, and it is difficult to further optimize the performance of the cover plate. Moreover, b...

[0003] The foldable display device includes a foldable display module and a foldable cover assembly covering the foldable display module. In the prior art, the cover in the foldable cover assembly usually adopts a polyimide cover (Cover Polyimide , CPI) or ultra-thin glass (Ultra Thin Glass, UTG) cover plate structure, however, the defects of the performance of these two cover plates are relatively obvious, it is difficult to further optimize the performance of the cover plate, and based on the existing cover plate Due to the unique structural design, the cover can only be bent in one direction, which also limits the development of foldable display devices.
