Optical filter box and touch display screen

Abstract

The invention relates to an optical filter box, which includes a glass substrate, a first embossing glue layer, a shading matrix layer, a first conducting layer, a color light resistance layer, a second embossing glue layer and a second conducting layer, wherein the glass substrate comprises a first surface and a second surface that are arranged oppositely; the first embossing glue layer is arranged on the first surface, and a first groove is formed in one side of the first embossing glue layer, far from the first surface; the shading matrix layer is arranged on the first surface; the first conducting layer is accommodated in the first groove, and includes first conducting patterns; the color light resistance layer is arranged on the surface of the first embossing glue layer, far from the glass substrate, and the projection of each color light resistance unit is in a grid unit on the shading matrix layer; the second embossing glue layer is arranged on the second surface, and a second groove is formed in the second embossing glue layer; the second conducting layer is accommodated in the second groove and includes second conducting patterns. The optical filter box realizes the touch operation and has the light filtering function, facilitates reduction of thickness and cost of electronic products. The invention further provides a touch display screen.

Description

technical field [0001] The invention relates to the field of plane display, in particular to an optical filter assembly and a touch display screen using the optical filter assembly. Background technique [0002] A touch screen is an inductive device that can receive input signals such as touch. 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 of 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 in...

AI Technical Summary

Problems solved by technology

[0004] The display screen mainly includes a polarizer, a filter assembly, a protective film, a liquid crystal module, and a thin film transistor (TFT, Thin Film Transistor). , already has a relatively large thickness, and when the touch screen continues to be attached to the display screen, its thickness will be further increased. Furthermore, one more lamination process means that the probability of product failure is increased and the production of the product is greatly increased. cost
