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 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.

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.
