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.

Abstract: A touch panel include a cover member, a drive electrode, a pressure detecting electrode, and a position detecting electrode. The pressure detecting electrode and the position detecting electrode are alternately arranged in a first direction. The pressure detecting electrode includes a plurality of pressure detecting sections, arranged side by side in a second direction orthogonal to the first direction, that each independently detect a pressure. The position detecting electrode includes a plurality of position detecting sections, arranged side by side in the second direction, that each independently detect a touched position. The area of a pressure detecting section is larger than the area of a position detecting section.
