Problems solved by technology

[0004] The display screen mainly includes polarizers, filter components, liquid crystal modules, and thin film transistors (Thin Film Transistor, TFT) stacked in sequence. Therefore, the display screen itself already has a relatively large thickness, and when continuing to attach the touch screen to the display screen, It will further increase its thickness. Furthermore, one more bonding process means increasing the probability of product failure and greatly increasing the production cost of the product.

Abstract

The invention relates to an optical filter box which comprises a glass substrate, a first conducting layer, an imprinting glue layer, a second conducting layer, a shading matrix layer and a color photoresist layer. The first conducting layer comprises first conducting patterns. The imprinting glue layer is arranged on the glass substrate. The second conducting layer comprises second conducting patterns, the second conducting patterns comprise continuous conducting grids, and the first conducting layer and the second conducting layer are arranged at intervals in the thickness direction of the imprinting glue layer to form a sensing structure. The wire width of one of a first conducting wire of the first conducting layer and a second conducting wire of the second conducting layer is 0.2-5micrometers, and projection of the other one on the shading matrix layer falls into the grids. The optical filter box can achieve touch operation and filtering, is beneficial to reducing the thickness of electronic equipment, and saves materials and assembly cost. 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 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] 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...
