touch screen

Abstract

The invention discloses a touch display screen, which comprises a TFT (thin film transistor) module, a liquid crystal module, a filter module and an upper polaroid, wherein the TFT module, the liquid crystal module, the filter module and the upper polaroid are stacked in sequence; the TFT module comprises a lower glass substrate and TFT electrodes arranged on the upper surface of the lower glass substrate; the filter module comprises an upper glass substrate, common electrodes and a filter layer, wherein the common electrodes and the filter layer are arranged on the lower surface of the upper glass substrate in a stacking manner; the touch display screen also comprises a transparent conducting layer arranged at one side, backing on to the liquid crystal module, of the upper glass substrate, and used for providing a touch function; the transparent conducting layer comprises a matrix and conducting nanometer wires filled in the matrix; the matrix is solidified transparent photosensitive resin; the transparent conducting layer is attached to the surface, backing on to one side of the filter module, of the upper polaroid, or attached to the surface, facing one side of the filter module, of the upper polaroid, or attached to the surface, facing one side of the upper polaroid, of the upper glass substrate. The touch display screen not only is in favor of the reduction of the thickness of an electronic product but also is capable of greatly reducing the material and assembly cost.

Description

technical field [0001] The present invention relates to a display screen, in particular to a touch display screen. Background technique [0002] A touch screen is an inductive device that receives an input signal from a touch light. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] Currently, electronic products with a touch display function include a display screen and a touch screen located on the display screen. However, as a component independent from the display screen, the touch screen needs to be ordered according to the size of the display screen when it is used in some electronic products that realize human-computer interaction, and then assembled. There are two main ways to as...

Problems solved by technology

[0004] As a combined module of polarizers, filters, liquid crystal modules, and TFTs, the display screen has a large thickness. At the same time, the touch screen and the display screen are independent components. When assembling electronic products, not only complex assembly processes are required, It will also increase the thickness and weight of electronic products again

Furthermore, one more assembly process means increasing the probability of defective products and greatly increasing the production cost of products
