Liquid crystal touch screen and manufacturing method thereof

Abstract

The invention provides a liquid crystal touch screen. The liquid crystal touch screen comprises a first polarizer, a first glass substrate arranged on the first polarizer, a liquid crystal layer arranged on the glass substrate, a second glass substrate arranged on the liquid crystal layer, a color light filter arranged on the second glass substrate, a first conductive electrode layer arranged on the color light filter, a second conductive electrode layer arranged on the first conductive electrode layer, and a second polarizer arranged on the second conductive electrode layer.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically relates to a liquid crystal touch screen and a manufacturing method thereof, which are used to increase touch sensitivity, reduce cost, and reduce the weight and thickness of the liquid crystal touch screen. Background technique [0002] The liquid crystal capacitive touch screen 2 is composed of a liquid crystal display (LCD) 21 and a capacitive touch screen 22 . The liquid crystal screen 21 is composed of polarizers 10, 60, optical filters 50, glass substrates 20, 40 and a liquid crystal layer 30, and its schematic structural diagram is as follows figure 1 and image 3 As shown, the touch panel (TP) 22 has two layers of conductive plates 70 , 80 , and the conductive plates 70 , 80 are formed by etching different patterns on the film material by means of laser. The two layers of conductive electrode plates 70 and 80 are driving electrodes and receiving electrodes...

AI Technical Summary

Problems solved by technology

Moreover, the touch screen 22 with the added upper cover film layer 90 is relatively thick and costly, and it is difficult for consumers who pursue lightness, lightness and low cost to accept the introduction of high-cost and heavy touch screen 22 into the market.
