Touch panel system and display device

A touch panel system according, comprising:

• a touch panel including a drive electrode, a position detection electrode, and a pressing detection electrode;
• and
• a controller configured to impart a drive signal to the drive electrode and acquire signal values from each of the position detection electrode and the pressing detection electrode,
• wherein the controller detects a position of an indicator based on the signal values obtained from the position detection electrode and calculates a magnitude of pressing of the indicator based on signal values in a pressing detection range corresponding to the detected position of the indicator among the signal values obtained from the pressing detection electrode,
• the controller amplifies a tentative value based on the signal values in the pressing detection range to calculate the magnitude of pressing of the indicator, and
• the controller calculates the magnitude of pressing of the indicator by amplifying the tentative value more greatly as a contact range of the indicator becomes wider.
