Bending liquid crystal display screen and manufacturing method and manufacturing device of bending liquid crystal display

Abstract

The invention discloses a bending liquid crystal display screen and a manufacturing method and a manufacturing device of the bending liquid crystal display screen. The method includes using plane glass substrates with different thermal expansion coefficients as an array substrate and a color film substrate; coating sealing glue at edges of surfaces of the array substrate and / or the color film substrate; heating the array substrate and the color film substrate, and adhering the expanded the array substrate and the expanded color film substrate together to form an adhesion substrate; and cooling the adhesion substrate to form a bend adhesion substrate with a bending degree. According to the manufacturing method, existing production devices are not required for large-scale changing to perform mass production of the bending liquid crystal display, the produced liquid crystal display screen is good in stability, and the bending degree can not be changed with the changes of using time.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display screens, and in particular, to a curved liquid crystal display screen and a manufacturing method and equipment thereof. Background technique [0002] The liquid crystal display screen has gradually become one of the most rapidly developing display devices due to its advantages of lightness and thinness. At present, due to the use of glass substrate materials, most liquid crystal displays are flat, but for some special applications, such as applications where advertising displays are installed on curved walls, curved displays are often required, but Restricted by the performance of glass substrate materials, it is difficult to manufacture curved liquid crystal displays. Among the existing methods of manufacturing curved liquid crystal display panels, some use resin-type materials that can realize bending as the substrate, and some use a film on the surface of the glass subst...

AI Technical Summary

Problems solved by technology

At present, due to the use of glass substrate materials, most of the LCD screens are flat, but for some special applications, such as the application of advertising screens installed on curved walls, curved screens are often required, but Limited by the performance of the glass substrate material, it is very difficult to manufacture a curved LCD display

In the existing methods of manufacturing curved liquid crystal display screens, some use resin-type materials that can realize bending as the substrate, and some use a thin film on the surface of the glass substrate to use the force of the film to realize the bending of the glass substrate. However, due to these methods In the manufactured curved display, the bending properties of the substrate are not rigid, and the stability is poor. As the use time increases, the curvature of the display will also change.
