Problems solved by technology

However, since the touch screen can only perceive the plane position of the touch (X axis and Y axis), it cannot perceive the vertical position information (Z axis) of the touch, that is, it cannot perceive the pressure of the touch

Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Glossary:

[0026] Touch chip is also called touch IC, and touch here refers to single-point or multi-point touch technology; IC, that is, integrated circuit, is a general term for semiconductor component products. Integrated circuits use semiconductor manufacturing technology to manufacture many transistors, resistors, capacitors and other components on a small single crystal silicon chip, and combine the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. circuit. It is represented by the letter "IC" (also with the text symbol "N", etc.) in the circuit. IC is a general term for semiconductor component products.

Abstract

The invention discloses a touch screen which comprises a touch screen body and an elastic plate. When any position of the touch screen body is stressed, the elastic plate deforms, so that the distance between a pressure induction electrode and a machine shell grounding area is changed, the self-capacity of the pressure induction electrode is changed, the variation of an induction capacitor is converted into the amplitude of pressure through a corresponding conversion device, and pressure detection is achieved. The invention further discloses a mobile phone which comprises a mobile phone body, a terminal machine shell, the touch screen, an adhesive flexible circuit board and a touch chip. When any position of the touch screen body is stressed, the elastic plate deforms, the self-capacity of the pressure induction electrode is changed, a variation signal of the induction capacitor is transmitted to the touch chip through the flexible circuit board, the variation signal of the induction capacitor is converted into a pressure signal through the touch chip to be output and displayed, and pressure detection is achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductor equipment, in particular to a touch screen and a mobile phone. Background technique [0002] At present, the touch screen has become the main human-computer interaction interface of personal mobile communication devices and comprehensive information terminals such as tablet computers, smart phones, medical equipment, and vehicle center consoles. Among them, the touch screen has become the main technology used in the touch interaction of small and medium-sized information terminals due to its characteristics of multi-touch, fast response, and long service life. However, since the touch screen can only sense the plane position of the touch (X axis and Y axis), it cannot perceive the vertical position information (Z axis) of the touch, that is, it cannot sense the pressure of the touch. [0003] Therefore, how to make the touch screen realize the pressure value of sensing touch is a technical ...
