Problems solved by technology

However, since the resistive touch screen realizes sensing by controlling the pressure, if the screen is designed to be multi-touch, the screen pressure becomes unbalanced, resulting in error-prone operations during multi-touch
In addition, the resistive touch screen is also more prone to damage to the touch part of the screen due to scratches, etc.

Abstract

The present invention relates to a pressure sensing-based touch panel and display device. The touch panel comprises a touch screen, infrared light emitters arranged below the touch screen and an infrared light receiver. The touch screen is deformed and bent by pressing, infrared light emitted by any infrared light emitter, after being reflected by the touch screen, is received by a corresponding infrared light receiver, and an included angle theta is formed between the infrared light emitted towards the touch screen by the infrared light emitter and a perpendicular line perpendicular to the touch screen. According to the pressure sensing-based touch panel and display device, a principle that bending deformation of the touch screen may be caused by a pressure and the total amount of received infrared light is influenced is used, pressure grades are obtained by calculating, and then corresponding applications or instructions are run according to the pressure grades.

Description

technical field [0001] The invention relates to screen touch technology, in particular to a touch screen based on pressure sensing, a display device and a method for realizing pressure sensing. Background technique [0002] With the rapid development of electronic communication technology, portable electronic products such as smart phones and tablet computers have penetrated into all aspects of people's daily life and become indispensable products in work, study and life. [0003] In the past, the human-computer interaction method of portable electronic products such as mobile phones usually adopts the button trigger method, that is, people perform command operations on electronic products through the buttons set on the electronic products. However, with the development of touch technology, the touch screen performs command operations through direct finger contact with the screen, and gradually replaces the button trigger mode with a simple, convenient and natural human-comp...
