Problems solved by technology

[0005] The object of the present invention is to provide a flexible display screen and a display device, which are used to solve the problem that when the flexible display screen is curled on the reel, due to the shear stress generated during the curling process, the shear stress will be transmitted to the flexible display screen and cause intermediate lamination. It is easy to peel off, resulting in abnormal display and reducing the technical problem of the service life of the rollable screen

Abstract

The invention provides a flexible display screen and a display device. The display device comprises a flexible display screen. The flexible display screen is used for being wound on a reel in a curledmode and comprises a back plate, a middle lamination layer and a cover plate which are arranged in a stacked mode. A plurality of continuous first trapezoidal structures are arranged on the upper surface of the back plate; a plurality of continuous second trapezoidal structures are arranged on the lower surface of the cover plate; when the flexible display screen is curled and wound on the reel,the first trapezoidal structure and the second trapezoidal structure are used for decomposing the shear stress generated by the reel in the curling process in the surface direction of the middle lamination layer to reduce the stress of the flexible display screen, so that the stripping phenomenon of the middle lamination layer of the flexible display screen is reduced, the risk of failure is reduced, and the service life of the flexible display screen is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display screen and a display device. Background technique [0002] At present, people are increasingly dependent on electronic products such as mobile phones, tablet computers, and smart wearable devices. In order to enhance user experience and enhance product competitiveness, the use of large screens has become a development trend. For the inconvenience of carrying large-screen electronic equipment, a rollable electronic display device emerges at the historic moment. When not in use, the electronic display screen can be rolled into the reel and stored in a small-sized form, which is easy to carry; Pull out from the reel. [0003] With the development of flexible electronic display technology and the release and launch of Huawei and Samsung's folding screen mobile phones, the competition in the folding screen mobile phone market is becoming more and more fierce. Wi...
