Curved-surface display panel preparation method, curved-surface display panel and curved-surface display device

Abstract

The invention relates to a curved-surface display panel preparation method, a curved-surface display panel and a curved-surface display device and belongs to the display technical field. The curved-surface display panel preparation method includes the following steps that: a first polarizing plate is attached to a display panel, wherein the first polarizing plate includes a polarizing layer and a directional shrinking layer; deformation processing is performed on the display panel coated with the first polarizing plate, so that the display panel can be bent and deformed under the stress action of the directional shrinking layer; and shaping processing is performed on the display panel and the first polarizing plate, so that bent and deformed shapes of the display panel and the first polarizing plate can be fixed. With the method adopted, fragmentation of the display panel in a production process due to external force-caused bending can be avoided, and the use intensity of the display panel can be improved, and the structure of a corresponding display device can be simplified, and therefore, the production yield and use stability of the curved-surface display panel can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a curved display panel, a curved display panel, and a curved display device. Background technique [0002] The display panel of the curved display device has a curved shape with a certain radian. Compared with the traditional flat display device, the curved display device has a larger viewing angle on the left and right sides of the screen, which can provide users with better visual experience. [0003] In the prior art, the processing method adopted by the curved display panel is to bend the display panel to a required radian by external force, and cooperate with the corresponding curved surface backlight module to assemble the curved surface display device. The process of this processing method is relatively complicated, and the display panel is prone to cracking during bending by external force, which reduces the production yield of the display panel pr...

Problems solved by technology

The process of this processing method is relatively complicated, and the display panel is prone to cracking during bending by external force, which reduces the production yield of the display panel product; In the process of production or use, the display panel is prone to local fragmentation when it is subjected to vibration or external force impact; a special structure needs to be set in the curved surface display device to maintain the curvature of the display panel, and its structure is more complicated than that of the flat display device. Display device materials and appearance structure are limited, the curvature of the display panel is difficult to maintain, and the stability of display device products is low
