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.
