Display device and protective cover plate

Abstract

The invention discloses a display device and a protective cover plate. The display device includes a display panel including a bent region and a non-bent region; an adhesive layer prepared on the surface of the display panel; and the protective cover plate attached to the display panel through the adhesive layer; wherein the protective cover plate includes a first portion corresponding to the non-bent region and a second portion corresponding to the bent region, the first portion having a hardness greater than the hardness of the second portion.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a protective cover. Background technique [0002] The size of the mobile phone screen has been developed to the limit, and the portability and one-handed operability of the screen above 6.5 inches are very poor. In order to obtain a larger display area without affecting the portability and one-handed operability, the mobile phone can be bent demand is growing stronger. However, the current upcoming or related concept products are not mature enough, and there are deficiencies in terms of technology and consumer recognition. Among them, the cover of the bendable mobile phone (Cover Window) is the key factor limiting the bendable screen. OLED has very good bendable properties, but the production of OLED screens also requires a cover (Cover Window) to play a protective role. Cover Glass) also has high light transmittance, hardness above 9H, and high ...

AI Technical Summary

Problems solved by technology

The current flexible cover is difficult to achieve the hardness and light transmittance of the glass cover, and cannot pass the reliability test, and consumers will not accept it

[0003] At present, the bendable mobile phones released on the market include the use of two rigid LCD screens, which are connected through mechanical structures to realize the bending function, but there are many problems: such as increasing the number of screen driver ICs, resulting in increased cost and power consumption; There will be irremovable borders in the bent part, which will affect the use of consumers; the screen is difficult to bend inward, and the bending angle is limited by the mechanical structure; the thickness of the whole machine module will increase greatly after bending, and the portability is poor

At present, there is also a bendable flexible screen. The thickness of the mobile phone and the cost of portability are better than the first solution, but this method also has many problems, such as the hardness of the Cover Window is not enough, and it is difficult to pass the reliability test. There are wrinkles in the bending area of ​​the rear Cover Window, etc., and it is not yet possible to achieve mass production and push it to consumers
