Pressure sensor and system of intelligent terminal

Abstract

The invention relates to the technical field of mobile terminals, in particular to a pressure sensor and system of an intelligent terminal. The pressure sensor includes a cantilever arm, a first flexible circuit board and a first pressure sensing chip, wherein the two ends of the cantilever arm are fixedly connected to the opposite faces of a middle frame and a screen of the intelligent terminal respectively. The first pressure sensing chip is fixedly arranged on the cantilever arm through a first flexible circuit board, and the first flexible circuit board is connected with a terminal processor of the intelligent terminal; when pressure exists on a screen of the intelligent terminal, the cantilever arm bends and deforms after being pressed by gravity, the first pressure sensing chip detects displacement information of the cantilever arm after bending deformation is generated from an initial position, the displacement information is sent to the terminal processor through the first flexible circuit board, and pressure sensing information is obtained after the displacement information is processed. And when the pressure on the screen of the intelligent terminal disappears, the cantilever arm recovers to the shape of the initial state, so that the control range of the screen of the intelligent terminal is expanded.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a pressure sensor and system for an intelligent terminal. Background technique [0002] With the development of mobile communications and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones has become more and more popular. Mobile phones have become an indispensable communication tool in people's lives, and are also entertainment equipment for most people. As the screen of the mobile phone is getting bigger and bigger, the content of the screen is more and more, and there are more and more various operation methods, so the operation of the mobile phone also encounters various problems, such as how to control the mobile phone. [0003] In the prior art, a pressure sensor is placed at both ends of the cover plate of the screen, but the defect of this solution is that the pressure sensing of the full screen cann...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a pressure sensor is placed at both ends of the cover plate of the screen, but the defect of this solution is that the pressure sensing of the full screen cannot be realized. Due to structural limitations and other reasons, when the pressure sensor is working There will be dead corners, especially at the edge of the mobile phone screen, where operations cannot be performed, thereby affecting the screen-to-body ratio of the mobile phone; another solution is to stick a pressure-sensitive sheet under the screen to sense the screen by detecting the deformation curvature of the screen. pressure, this solution will also have the above-mentioned dead angle problem
