The invention discloses an electronic device and a pressure detection method thereof. The electronic device comprises a touching driving chip, a first detection electrode, a second detection electrode and a controller. The touching driving chip is connected with the first detection electrode and the second detection electrode, and is used for driving the first detection electrode and the second detection electrode to conduct first input data scanning, and position information and pressure information of a first touching point are obtained; the controller is connected with the touching driving chip, and is used for judging whether a touching point is an interference pressure point or not according to the result of first input data scanning, if the touching point is the interference pressure point, the position information and the pressure information of the first touching point are insulated. The interference pressure point can be detected when the electronic device is subjected to pressure detection, position information and pressure information of the interference pressure point are insulated, and when the electronic device is subjected to pressure detection, the influence caused by water drops and oil stains or mild deformation of the electronic device on the pressure detection accuracy is avoided.
Description
technical field [0001] The invention relates to the technical field of pressure detection, and more specifically, to an electronic device and a pressure detection method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with pressure detection functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become the Indispensable and important tool. [0003] When the existing electronic equipment with pressure detection function performs pressure detection, water droplets, oil stains or slight deformation of the electronic equipment will affect the accuracy of the electronic equipment for pressure detection. Contents of the invention [0004] In order to solve the above problems, the present invention provides an electronic device and its pressure detection method, which avoids the influence of water droplets, oil stains or s...
