Abstract

The invention discloses a metal mesh based touch screen capable of sensing touch position and pressure. The touch screen comprises: a transparent substrate; a first metal mesh layer, which is a position sensing layer and senses plane position information of touch by measuring capacitance change; a second metal mesh layer, which is a pressure sensing layer and senses vertical pressure information of touch by measuring resistance change; and a signal control apparatus, which is connected with the first metal mesh layer and the second metal mesh layer and is used for receiving electrical signals of the two metal mesh layers and analyzing a plane position and a vertical pressure of the touch action. The metal mesh layers are adopted as the touch position sensing layer and the pressure sensing layer respectively, and the plane position and the vertical pressure of the touch action are sensed by measuring the capacitance change and the resistance change of metal meshes, thereby realizing transformation of a conventional interpersonal interaction form from a two-dimensional mode to a three-dimensional mode.

Description

technical field

[0001] The invention relates to the technical field of touch screens, in particular to a touch screen capable of sensing touch position and pressure based on a metal grid. Background technique

[0002] With the development and progress of mobile electronic product equipment technology, the use of touch screens is particularly important. At present, there are many different touch sensing technologies, mainly capacitive touch screens, which mainly recognize the plane position information of the finger touch (by obtaining the capacitance changes of the electrodes in the X-axis direction and the Y-axis direction of the point respectively, to accurately calculate location of the touch point). With the continuous improvement of people's requirements for touch technology, the ideal touch screen not only needs to be able to sense the plane position information of touch, but also needs to be able to sense the vertical pressure (Z-axis direction) of touch, so as to re...
