Problems solved by technology

The display cover used to protect the display panel in the flexible display device also needs to have the performance of bending or folding. However, due to the performance limitation of bending or folding, compared with the cover used in the traditional rigid display device, the flexible display device The impact resistance of the display cover plate is poor. When the display device is subjected to external impact, it is easy to cause problems such as broken bright spots or even cracks on the display panel, which will affect the service life of the display panel.

Abstract

The invention discloses a display cover plate, a display device and a preparation method, relates to the technical field of display, and can improve the rigidity of the display cover plate applied to a flexible display device so as to improve the impact resistance and avoid the problems that a display panel generates display broken bright spots and even cracks and the like due to the fact that the display device is subjected to external impact. The display cover plate comprises a first material layer; a second material layer; the second material layer is arranged between the first material layer and the third material layer, and the rigidity of the first material layer and the rigidity of the third material layer are both larger than that of the second material layer; under the condition that the display cover plate is used for being fixedly connected with a display panel, the first material layer is close to the display panel relative to the third material layer, or the third material layer is close to the display panel relative to the first material layer.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display cover plate, a display device and a manufacturing method. Background technique [0002] With the development of display technology, flexible display devices are favored by consumers due to their bendable or foldable properties. The display cover used to protect the display panel in the flexible display device also needs to have the performance of bending or folding. However, due to the limitation of the bending or folding performance, compared with the cover used in the traditional rigid display device, the flexible display device has The display cover plate has poor impact resistance. When the display device is subjected to external impact, it is easy to cause the display panel to display broken bright spots or even cracks, thereby affecting the service life of the display panel. SUMMARY OF THE INVENTION [0003] The embodiments of the present applic...
