Optical filter module and touch display screen with same

Abstract

An optical filter module comprises an optical filter layer and a protecting layer which are stacked. The optical filter layer comprises an optical filter substrate, a shading part disposed on the optical filter substrate and a plurality of optical filter units. The optical filter units form an optical filter part. Intervals are arranged among the optical filter units. The shading part is grid-shaped and comprises a plurality of crossed grid lines which are located at the intervals of the optical filter units. The grid lines form a plurality of grid units. Each optical filter unit is accommodated in one corresponding grid unit. The protecting layer sequentially comprises a protecting film substrate, a pressing adhesive layer and a conducting layer, wherein the conducting layer is embedded on one side, away from the protecting film substrate, of the pressing adhesive layer, and the conducting layer comprises a first conducting pattern and a second conducting pattern which form an induction structure and are made of conducting meshes formed by a plurality of conducting wires. By the optical filter module, touch control and optical filter can be achieved simultaneously, thickness of electronic products is reduced, and materials and assembling cost are saved. The invention further provides a touch display screen.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an optical filter module and a touch display screen using the optical filter module. 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-compu...

AI Technical Summary

Problems solved by technology

[0004]The display screen mainly includes polarizer, filter module, liquid crystal module and thin film transistor (TFT, Thin Film Transistor). When the module and thin-film transistor are combined into a display screen, it already has a large thickness, and when the touch screen is continued to be attached to the display screen, its thickness will be further increased. Moreover, one more lamination process means that the product has been increased. The probability of bad, greatly increasing the production cost of the product
