Abstract: The present invention relates to the field of touch technologies, and provides a force detection method, apparatus and device. The force detection method includes: receiving a deformation caused by external force and identified by at least one sensing electrode, and converting the deformation into a corresponding raw feature value characterized by an electrical signal, wherein the raw feature value corresponds to the force; and calculating force information fed back by the at least one sensing electrode according to the raw feature value of the at least one sensing electrode. With the force detection method, apparatus and device according to the invention, when a plurality of positions is pressed by force, the force information at each position may be accurately acquired. In practice, multi-finger press detection may be implemented on the touch screen by using fewer electrodes, thereby reducing the cost and improving the user experience.

Abstract: A method for determining a change of an initial distance of a sensing electrode is provided. The method includes: calculating a real-time pressure output by each sensing electrode according to real-time feature data output by each sensing electrode in a touch screen when a pressure is applied on the touch screen and a corresponding relationship between the feature data and the pressure; rectifying the real-time pressure output by each sensing electrode according to prestored relative elastic coefficients at different press positions relative to each sensing electrode; and determining a sensing electrode whose initial distance is changed among all the sensing electrodes according to a difference between the rectified real-time pressures output by different sensing electrodes, to calibrate the corresponding relationship between the feature data and the pressures of the sensing electrode whose initial distance is changed.
