Abstract

The invention provides a pressure detecting method and equipment, and relates to the field of electronic equipment. The method comprises the following steps of: responding to an object to contact a capacitive touch screen, and obtaining the first capacitance distribution information of the capacitive touch screen at the first moment and the second capacitance distribution information of the capacitive touch screen at the second moment in the contact process; determining the contact pressure change value of the object and the capacitive touch screen in the second moment and the first moment at least according to the elastic parameters of the object, the first capacitance distribution information and the second capacitance distribution information. The method and the equipment have the advantage that the pressure detection by the capacitive touch screen is realized under the condition of not increasing the hardware cost.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a pressure detection method and equipment. Background technique [0002] With the popularity and development of electronic devices, more and more electronic devices use touch screens as input interfaces. Existing touch screens mainly include resistive touch screens and capacitive touch screens. Since the capacitive touch screen has higher sensitivity, higher light transmittance, longer service life, etc., the capacitive touch screen is more favored by consumers. [0003] The basic principle of the capacitive touch screen is that when the finger or the human body approaches or touches, by measuring the changing parasitic capacitance outside the fixed capacitance between the corresponding electrodes of the touch screen, the touch position of the finger and the proximity parameters of the human body can be determined. [0004] In order for a capacitive touch...
