Example Embodiment

[0023] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0024] The resistive touch screen provided by the embodiment of the present invention only needs upper and lower conductive layers, isolation points, and a flexible printed circuit board in structure. The lower conductive layer serves as a voltage distribution layer. One side of the resistive touch screen is attached with isolation points, and the flexible printed circuit board is located on the lower conductive layer. On the side of the isolation point, the lower conductive layer is electrically connected, and the upper conductive layer is used for detecting voltage and bonding with the flexib...

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...
