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

Abstract

The invention discloses a single-layer multi-point conducting film which comprises a transparent substrate, first conducting layers, insulating layers, second conducting layers, first lead electrodes and second lead electrodes. The transparent substrate comprises a body and at least one flexible connecting portion, one side of the body extends to form each flexible connecting portion, the width of each flexible connecting portion is smaller than that of the side, which extends to form the flexible connecting portion, of the body, the flexible connecting portions are provided with conducting circuits, an induction area and a frame area are arranged on the body, and the frame area is positioned at the edge of the induction area; the first conducting layers are arranged in the induction area; the insulating layers are positioned above first conducting wires and are embedded in grid grooves; the second conducting layers are arranged in the induction area of the transparent substrate and are separated from the first conducting layers by the aid of the insulating layers, and second conducting wires of the second conducting layers are transparent conducting wires. The single-layer multi-point conducting film has the advantage of low cost. The invention further provides a single-layer multi-point touch panel comprising the single-layer multi-point conducting film.

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
