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

Abstract

A single-layer multi-touch conductive film, which includes: a transparent substrate, including a sensing area and a frame area adjacent to the sensing area; a first conductive layer, in the shape of a grid, arranged on the transparent substrate In the sensing area, the first conductive layer includes first conductive threads crossing each other, and the sensing area is provided with grid grooves, and the first conductive layer is accommodated in the grid grooves; the insulating layer is located in the first above the conductive thread and embedded in the grid groove; the second conductive layer is in the form of a grid, and is arranged in the sensing area of ​​the transparent substrate, separated from the first conductive layer by the insulating layer, The second conductive layer includes second conductive threads crossing each other, wherein the grid of one of the first conductive layer and the second conductive layer is a regular grid, and the grid of the other layer is a random grid. grid. The cost of the above-mentioned single-layer multi-touch conductive film is relatively low. The invention also provides a single-layer multi-point touch screen.

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...
