Abstract

The invention discloses a method and device for detecting pressure in a mobile terminal and belongs to the technical field of terminals. The method includes the steps that the capacitance values between transparent electrodes and a supporting column array in a liquid crystal layer of a liquid crystal display screen are detected; the pressure value, acting on the interior of the liquid crystal display screen, of an operating body is determined according to the detected capacitance values. The pressure value in the liquid crystal display screen is determined by detecting the capacitance values between the transparent electrodes arranged on the liquid crystal layer in the liquid crystal display screen and the supporting column array in the liquid crystal layer, it is achieved that third-dimension pressure induction except touch induction is detected in the liquid crystal display screen, more functions can be achieved through the detected pressure value, and man-machine interactivity is improved.

Description

technical field [0001] The present disclosure relates to the field of display technologies, and in particular to a method and device for detecting pressure in a mobile terminal. Background technique [0002] With the development of the liquid crystal display technology, the liquid crystal display has more and more functions, which can realize the sensing of the touch position. By adding a layer of touch panel on the liquid crystal display, the coordinate position where the capacitance change occurs can be determined by detecting the capacitance change in the touch panel, and then the user's touch position on the liquid crystal display can be determined. This method only provides a method for determining two-dimensional coordinates on the liquid crystal display screen, but cannot provide pressure sensing in three-dimensional coordinates. Contents of the invention [0003] In order to solve the problems of related technologies, embodiments of the present disclosure provide ...
