Light polarization and filtration module and touch display screen

Abstract

A light polarization and filtration module comprises a light filter module, a polarizing sheet module, a protective adhesive layer and a conducting layer. The light filter module comprises a bearing substrate, a shading matrix and color light resists scattered in the shading matrix, and the shading matrix comprises grid lines formed by shading materials; the polarizing sheet module comprises a polarizing sheet substrate; the protective adhesive layer is arranged on the polarizing sheet substrate; the conducting layer is embedded on the protective adhesive layer and comprises first conducting patterns and second conducting patterns, the first conducting patterns and the second conducting patterns are arranged at intervals in the extension direction of the protective adhesive layer and comprise conducting grids formed by cross connection of conducting silk threads, and projection shadows of the conducting silk threads on the shading matrix drop on the grid lines of the shading matrix. According to the light polarization and filtration module, the touch operation and the polarized light emergency function can be achieved simultaneously, a touch screen is not required to be assembled when the module is used in a display screen, the electronic product thickness is reduced, and costs are saved.

Description

technical field [0001] The invention relates to a touch screen, in particular to a polarizer module and a touch screen. Background technique [0002] A touch screen is an inductive device that receives an input signal from a touch lamp. 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] At present, 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 of the display screen, the touch screen needs to be used according to the display screen when it is used in some electronic products that realize human-computer interaction. The size of the order is ordered, and then assembled. There ar...

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, but also Increase the thickness and weight of electronic products again. Furthermore, one more assembly process means increasing the probability of product failure and greatly increasing the production cost of the product.
