Liquid-crystal display with touch function and preparation method thereof

Abstract

The invention relates to a liquid-crystal display with a touch function and a preparation method thereof. The liquid-crystal display with the touch function comprises a first substrate and a second substrate, wherein the first substrate and the second substrate are oppositely packaged together and clamp a liquid crystal therebetween; the external surface of the first substrate is provided with a first polaroid, and the external surface of the second substrate is provided with a second polaroid with an integral structure and a touch structure layer for determining a position coordinate of a touch point. The invention not only causes the liquid crystal display to directly realize the touch function, but also realizes zero-distance combination of no gap between the touch structure and a liquid crystal panel through integrating the touch structure layer for determining the position coordinate of the touch point on the second substrate, thereby the technical defects of entering ashes and entering aqueous vapor of a conventional touch screen are completely overcome, and the technical defect of reducing display quality due to a Newton's ring generated by the conventional touch screen can be effectively avoided. Besides, the invention has the advantages of small thickness, light weight, material cost reduction, process step reduction, production time shortening and the like.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display with touch function and a preparation method thereof. Background technique [0002] With its advantages of ease of use, durability, fast response, and space saving, more and more people feel the superiority and convenience of using a touch screen. The touch screen gives the multimedia system a new look, so it is a very attractive new multimedia interactive device. The touch screen greatly simplifies the use of electronic products such as computers and mobile phones, and expands the application range of electronic products such as computers and mobile phones in the public information market. [0003] In the prior art, a liquid crystal display with a touch function usually installs a touch panel on the liquid crystal display. The coordinate position of the touch point on the screen is measured through the touch panel, and the toucher's inten...

AI Technical Summary

Problems solved by technology

Practical applications have found that due to the gap between the assembled touch panel and the liquid crystal display, not only is there a technical defect that dust and water vapor are easy to enter the gap, but also the gap will cause the refraction of light to produce a rainbow-like Newton ring phenomenon, which reduces the display quality

In addition, the touch screen of the prior art assembly structure also has technical defects of relatively large thickness and weight
