Abstract
A sensing method based on a capacitive touch panel is provided. The capacitive touch panel includes a touch sensor, a pressure sensor, and a deformable insulating layer disposed between the touch sensor and the pressure sensor to form a gap between the touch sensor and the pressure sensor. In the sensing method, at least one touch position is located using the touch sensor. Pressure information is sensed based on a number of self-capacitance variation values detected from the pressure sensor. The self-capacitance variation values are generated by a deformation of the deformable insulating layer under an external force.
