Abstract

The embodiment of the present invention discloses a terminal, which is used to solve the problem of high cost in implementing pressure touch in the prior art, and save cost. The terminal includes a cover plate, a display module, and a metal middle frame, wherein the display module is located between the cover plate and the metal middle frame, the metal middle frame is grounded, and the terminal further includes: a conductive layer, the conductive layer is attached to the lower surface of the display module; there is at least one gap between the conductive layer and the metal middle frame, wherein the conductive layer, the metal middle frame and the At least one gap forms at least one capacitor, wherein the change in capacitance of the at least one capacitor reflects the magnitude of at least one pressure acting on the cover plate.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a terminal. Background technique [0002] As a human-computer interaction module, the touch screen is more and more widely used in electronic devices such as mobile phones, ipads and personal computers (English full name: PersonalComputer, abbreviation: PC), and the requirements for the intuitive feeling of its human-computer interaction are also increasing. The higher, for example: pressure touch through pressure sensing. [0003] At present, the structure of the pressure material required for pressure sensing is a sandwich structure, and the pressure material is assembled on the pressure sensor, so that the four corners below the liquid crystal display (full name in English: Liquid Crystal Display abbreviation: LCD) are arranged using a dedicated independent pressure sensor. [0004] However, the pressure material is a special pressure material, and the material cost is high, ...
