Filter Assembly and Touch Display

Abstract

The invention relates to an optical filter assembly, comprising: a glass substrate; a first conductive layer arranged on a side of an embossed adhesive layer close to the glass substrate, including a first conductive pattern; an embossed adhesive layer; arranged on the glass substrate on the material; the second conductive layer, embedded on the side of the embossed adhesive layer away from the glass substrate, includes a second conductive pattern, the second conductive pattern includes a continuous conductive grid, the conductive grid is formed by crossing conductive threads, the first The conductive layer and the second conductive layer are separated from each other in the thickness direction of the embossed adhesive layer to form an induction structure; it also includes a light-shielding matrix layer and a color photoresist layer, wherein the line width of the conductive threads of the first conductive layer and the second conductive layer is 0.2 microns to 5 microns. The optical filter assembly can be operated by touch and has a light filtering function, which is beneficial to reduce the thickness of electronic products, and also saves material and assembly costs; the conductive thread can ensure visual transparency within the above-mentioned line width range. A touch display is also provided.

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 touch input signals. 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 interaction, ...

AI Technical Summary

Problems solved by technology

[0004] The display screen mainly includes polarizers, filter components, liquid crystal modules, and thin film transistors (TFT, Thin Film Transistor) stacked in sequence. Therefore, the display screen itself already has a 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.
