Abstract
A touch panel system includes a touch panel including a drive electrode, a position detection electrode, and a pressure detection electrode, and a controller configured to impart a drive signal to the drive electrode and acquire a signal value from each of the position detection electrode and the pressure detection electrode. The controller is configured to detect a touch range by a pointer based on the signal value obtained from the position detection electrode, determine a pressure detection range corresponding to the touch range, of the signal value obtained from the pressure detection electrode, and calculate a magnitude of a pressure by the pointer based on the signal value in the pressure detection range.
