Abstract
A touch panel system includes a touch panel, a cover member overlapping the touch panel, and a controller. The controller includes a position detection unit configured to detect a position of a pointer, based on a signal value obtained from a position detection electrode, an amplification processing unit configured to perform amplification processing on at least one signal value in a pressing force detection range corresponding to the position of the pointer detected by the position detection unit among signal values obtained from a pressing force detection electrode, and a pressing force detection unit configured to calculate magnitude of a pressing force generated by the pointer, based on a signal value after the amplification processing being a signal value in the pressing force detection range including a signal value obtained by amplification by the amplification processing unit.
