Problems solved by technology

However, since the pressure-sensitive touch screen or touch button obtains the relevant position coordinates and pressure values ​​by detecting the strain of the medium, the strain of the medium must reach the minimum range that the strain sensor can detect, so this application is subject to the dielectric material. Strength and thickness limitations, if the medium is thicker and stronger, it is difficult to detect lighter touch movements, which also makes the touch operation not smooth enough

Abstract

The present invention provides a pressure measurement structure and touch control device, comprising a substrate and a sensor, the substrate being provided with an area of strain concentration and an area of non-strain concentration, and the sensor being arranged in the vicinity of strain concentration or within the scope of the area of strain concentration. The substrate at the area of strain concentration is thinner than the substrate at the area of non-strain concentration. The area of non-strain concentration is sensitive to stress reaction, and obvious to strain transformation in such a manner to generate detectable electrical signals when applying pressure on the surface of the substrate. The touch control device comprises at least one pressure measurement structure which has the advantages of sensitive operation and easily controllable cost, and is suitable for environments with high requirement, in wide application fields, such as dust-free and security and protection, etc.

Description

technical field [0001] The invention belongs to the field of touch technology, in particular to a pressure detection structure and a touch device. Background technique [0002] With the development of smart electronic products in recent years, touch screens and touch buttons are widely used in various electronic products and other related products. Its features of intuitive human-computer interaction interface, easy operation and easy definition of virtualization make the operation of these products more humanized and the functions more diversified. Touch screens and touch keys are more and more widely used, and they are required to have more functions and higher reliability to be used in more occasions. Existing touch screens and touch keys include various types, such as capacitive, resistive, infrared, and surface acoustic wave types. These touch screens and touch buttons detect the position of touch by detecting changes in contact resistance, capacitance, blocked infrar...
