Single-layer multi-point touch screen and its single-layer multi-point conductive film

Abstract

A single-layer multi-point conductive film, comprising a transparent base, a decorative conductive layer, a first conductive layer, an insulating layer, a second conductive layer, a first lead electrode and a second lead electrode; the transparent base includes a body and a part of the body At least one flexible connecting part formed by side extension, the decorative conductive layer is located in the projection area of ​​the frame area on the transparent substrate; The frame area at the edge of the area; the first conductive layer is arranged in the sensing area; the insulating layer is located above the first conductive thread and embedded in the grid groove; the second conductive layer is arranged in the sensing area of ​​the transparent substrate , and separated from the first conductive layer by the insulating layer, the first lead electrode and the second lead electrode are located on the surface of the decorative conductive layer. The above-mentioned single-layer multi-point conductive film has the characteristics of low cost. At the same time, a single-layer multi-point touch screen using the above-mentioned single-layer multi-point conductive film is also provided.

Description

technical field [0001] The invention relates to a touch conductive film, in particular to a single-layer multi-point conductive film and a single-layer multi-point touch screen using the single-layer multi-point conductive film. Background technique [0002] The transparent conductive film is a film with good conductivity and high light transmittance in the visible light band. At present, transparent conductive films have been widely used in fields such as flat panel displays, photovoltaic devices, touch panels, and electromagnetic shielding, and have an extremely broad market space. [0003] 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. The manufacturing technology of touch screen is developing rapidly, but for the traditional single-layer multi-point conductive film, it needs to be attached to the flexib...

AI Technical Summary

Problems solved by technology

The manufacturing technology of touch screen is developing rapidly, but for the traditional single-layer multi-point conductive film, it needs to be attached to the flexible printed circuit board (Flexible Printed Circuit, FPC), and need to carry out laminating process, which increases the cost of manpower and material resources

At the same time, in the ITO corresponding process, 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 waste of precious metals, which in turn makes the product cost high. Lead to higher cost of traditional single-layer multi-point conductive film
