Problems solved by technology

[0004] However, when the above-mentioned touch display device is touched and pressed, whether one finger or multiple fingers are used, the change of the distance H between the first electrode 101 and the second electrode 102 can only detect the pressing force, but cannot Detect the number of fingers that touch and press, so that different commands can be triggered when a single finger is pressed and multiple fingers are pressed, that is, multi-point pressure touch cannot be realized, which limits the range of touch commands. calling scope

Abstract

A substrate includes a plurality of force sensitive resistors, among which at least two force sensitive resistors connected in series forms a force sensing unit, wherein the first end of the force sensing unit applied with a first voltage, and the second end of the force sensing unit applied with a second voltage which is different from the first voltage; a readout signal line tapped between two adjacent force sensitive resistors connected in series; and the force sensitive resistors are made of piezoresistive material.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate, a display device and a pressure recognition method thereof. Background technique [0002] Touch display devices are more and more used in the field of display technology in various industries. When a user touches the touch screen of the touch display device with a finger, the touch display device can sense the touch position of the finger within the plane of the touch screen. , and the touch pressure of the finger, so that the user can realize human-computer interaction only by touching the pattern or text on the touch screen. [0003] The touch display device mentioned above, such as a mobile phone such as figure 1 As shown, it includes a mobile phone middle frame 103 and a touch screen 100 installed on the mobile phone middle frame 103 . In order to detect the touch pressure of the finger, the above-mentioned mobile phone also includes a first electrode 101 and ...
