TOUCHPAD AND ITS FORCE SENSING DATA CALIBRATION METHOD

A touchpad and its force-sensing data correction method are provided. The touchpad has a force-sensing layer and a touch-sensing layer. The force-sensing layer has multiple force-sensing points. The touch-sensing layer has multiple touch-sensing points. One force-sensing point corresponds to n touch-sensing points. The force-sensing information received by the force-sensing layer is adjusted by using the touch-sensing information received by the touch-sensing layer, so that the resolution of the adjusted force-sensing information is higher than the resolution of the original received force-sensing information. In this way, the purpose of calibrating the force-sensing information is achieved, so as to improve the accuracy of determining the force applied by the object during the operation of the touchpad.
