Single-layer multi-point type touch conducting film and single-layer multi-point type touch screen

Abstract

The invention provides a single-layer multi-point type touch conducting film, and further provides a single-layer multi-point type touch screen. The single-layer multi-point type touch conducting film comprises a transparent substrate, a first conducting layer, an insulating layer and a second conducting layer, wherein the transparent substrate comprises a sensing region and a frame region adjacent to the sensing region; the first conducting layer is of a grid shape, is arranged in the sensing region of the transparent substrate, and comprises crossed first conductive threads, the sensing region is provided with a grid groove, and the first conducting layer is accommodated in the grid groove; the insulating layer is located above the first conductive threads and is embedded into the grid groove; the second conducting layer is of a grid shape, is arranged in the sensing region of the transparent substrate, is separated from the first conducting layer through the insulating layer, and comprises crossed second conductive threads, grids of the first conducting layer or grids of the second conducting layer are regular grids, and grids of the other layer are random grids. The single-layer multi-point type touch conducting film is low in cost.

Description

【Technical field】 [0001] The invention relates to a touch conductive film, in particular to a single-layer multi-point touch conductive film and a single-layer multi-point touch screen using the single-layer multi-point touch conductive film. 【Background technique】 [0002] The transparent conductive film is the sensing element in the touch screen that receives input signals such as touch. Currently, the ITO (Indium Tin Oxide) layer is a vital component in transparent conductive films. Although the manufacturing technology of touch screen is developing rapidly, taking the projected capacitive screen as an example, the basic manufacturing process of the ITO layer has not changed much in recent years, and ITO coating and ITO patterning are always unavoidable. [0003] Indium is an expensive metal material, so using ITO as the material of the conductive layer greatly increases the cost of the touch screen. Furthermore, in the patterning process of the ITO conductive layer, th...

AI Technical Summary

Problems solved by technology

Although the manufacturing technology of the touch screen is developing rapidly, taking the projected capacitive screen as an example, the basic manufacturing process of the ITO layer has not changed much in recent years. It is always inevitable to need ITO coating and ITO patterning.

[0003] Indium is an expensive metal material, so using ITO as the material of the conductive layer greatly increases the cost of the touch screen

Furthermore, in the patterning process of the ITO conductive layer, the entire plated ITO film needs to be etched to form an ITO pattern. In this process, a large amount of ITO is etched away, resulting in a large amount of precious metal waste and pollution.

[0004] Therefore, the ITO material and the corresponding process make the product cost high, resulting in a high cost of the traditional single-layer multi-touch conductive film
