Abstract

The invention applies to the field of touch screens, and provides a resistance-type touch screen and a manufacturing method thereof. The touch screen comprises a lower conducting layer, a flexible printed circuit board and an upper conducting layer, wherein the lower conducting layer is taken as a voltage distribution layer; isolation points are attached to one side of the lower conducting layer; the flexible printed circuit board is positioned on the isolation-point side of the lower conducting layer and is electrically connected with the lower conducting layer; and the upper conducting layer is used for detecting voltage and is bonded to the flexible printed circuit board. The resistance-type touch screen provided by the invention has the advantages of leaving out conductive electrodes, insulation-layer printing, acid etching, demoulding and other intermediate links in a process, shortening process flow, improving product yield and saving manpower and material resources.

Description

technical field

[0001] The invention belongs to the field of touch screens, in particular to a resistive touch screen and a manufacturing method thereof. Background technique

[0002] As a kind of human-computer interaction interface, touch screen has entered various fields, especially widely used in portable electronic equipment and public inquiry equipment. A resistive touch screen is a sensor that converts the physical position of a touch point (X, Y) in a rectangular area into a voltage representing the X-axis coordinates and the Y-axis coordinates. Many Liquid Crystal Display (LCD) modules use Resistive touch screen. The screen part of the resistive touch screen is a multi-layer composite film that matches the surface of the display. It consists of a layer of glass or plexiglass as the base layer, and the surface is coated with a transparent conductive layer. Scratch-resistant plastic layer, its inner surface is also coated with a transparent conductive layer, and the...
