Screen body of touch screen

Abstract

The invention provides a screen body of a touch screen, which comprises a first conducting layer, a second conducting layer and a third conducting layer, wherein the first conducting layer is at least provided with a first pair of edges, which comprises a first edge and a second edge, and the second edge is roughly parallel to the first edge, so that when a power source is loaded onto the first edge and the second edge, a voltage drop can be caused on the first conducting layer between the first edge and the second edge; the second conducting layer is separated from the first conducting layerby a first partitioning layer and provided with a second pair of edges, which comprises a third edge and a fourth edge, and the third edge is roughly parallel to the fourth edge, so that when the power source is loaded onto the third edge and the fourth edge, a voltage drop can be caused on the second conducting layer between the third edge and the fourth edge; and the third conducting layer is separated from the second conducting layer by a second partitioning layer and provided with a plurality of conducting areas which are insulated from each other.

Description

technical field [0001] The invention relates to touch screen technology, in particular to a touch screen body. 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. By pressing the touch screen with a finger or a touch pen, the user can click a certain function button on the screen or input text, graphics and other contents by handwriting. [0003] In principle, touch screens can be divided into four basic types: resistive touch screens, capacitive touch screens, infrared touch screens, and surface acoustic wave touch screens. Among them, the resistive touch screen is the lowest cost and most widely used touch screen. Regardless of the type of touch screen, it is composed of a touch screen body and a touch screen controller. [0004] Resistive touch screens are divided into four-wire resistive touch screens and five-wire...

AI Technical Summary

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: the touch screen in the prior art only includes a resistive touch sensing device, and cannot identify the exact positions of two touch points at the same time, so that gesture recognition with multiple fingers cannot be performed.
