Touch liquid crystal display device and manufacturing method thereof

Abstract

The invention provides a touch liquid crystal display device and a manufacturing method thereof and relates to the technical filed of display. The touch liquid crystal display device is lower in production cost compared with the prior art, and effectively improves the whitening phenomenon of touch display. The touch liquid crystal display device comprises a touch screen, a liquid crystal display screen and an adhesion layer between the touch screen and the liquid crystal display screen, the adhesion layer comprises a plurality of non-contact adhesion portions, and the adhesion portions are in contact with the touch screen and the liquid crystal display screen respectively for fixing the touch screen and the liquid crystal display screen. The manufacturing method is used for the production of the touch liquid crystal display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch-sensitive liquid crystal display device and a preparation method thereof. Background technique [0002] The touch display can be operated only by the user touching the icon or text on the display with his finger, which makes the human-computer interaction more straightforward. Today, touch displays have been widely used in all aspects of social life. [0003] like figure 1 As shown, the touch display generally includes a touch screen 10 and a liquid crystal display 20, and the touch screen 10 and the liquid crystal display 20 are fixed by bonding glue 30, wherein the liquid crystal display 20 generally includes a color filter substrate 21 and an array substrate 22 , and the liquid crystal 23 located between the color filter substrate 21 and the array substrate 22 . [0004] The display principle of the liquid crystal display is: after the liquid crystal display is pow...

AI Technical Summary

Problems solved by technology

[0005] When the common electrode and the pixel electrode are located on the same side of the liquid crystal, the inventors have found that there are at least the following problems in the prior art: figure 2 As shown, when the touch display is subjected to a bending test, the touch screen 10 is deformed by an external force, and part of the external force is transmitted to the adhesive 30

[0006] At present, a thinned liquid crystal display is used to solve the whitening phenomenon, but in the process of producing the liquid crystal display, it is necessary to thin the liquid crystal display after box alignment, which adds an additional process and increases the production cost; And thinning is easy to damage the LCD screen, thus reducing the product yield
