Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a folding cover plate and a display device. A first surface of a substrate is provided with a first groove in a bending area. When the folding cover plate is in a horizontal unfolding state, the maximum width of the first groove is larger than the width of the bending area in the first direction. At least one of the two ends of the first groove is located in the non-bending area. The first flexible layer is arranged in the first groove. When the cover plate is bent and folded through the bending area, the curvature radius corresponding to the bending area is decreased. And the deformation of the part of the first flexible layer in the bending area is greater than the deformation of the part of the first flexible layer in the non-bending area. In the first direction, at least one of the two ends of the first flexible layer is located in the non-bending area. At least one of the two ends of the first groove is located in the non-bending area, so that the situation that at least one of the two ends, located at the first groove, of the first flexible layer is stripped and falls off from the first groove in the repeated bending process of the folding cover plate can be prevented, and therefore the service life of the folding cover plate is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a folding cover and a display device. Background technique [0002] With the development of flexible active-matrix organic light-emitting diode (AMOLED) display technology, folding screens have gradually become a trend. The folding cover is an important material part of the folding screen, and its performance is getting more and more attention, and users have higher and higher requirements for the folding cover. [0003] Existing folding covers usually use ultra-thin glass (UTG) covers. However, the existing ultra-thin glass cover plate has the disadvantages of not being durable and having a short service life, which restrict the wide application of the folding cover plate. Contents of the invention [0004] Based on this, it is necessary to provide a folding cover and a display device to address the above technical problems. [0005] A folding cover, comprising: ...
