摘要： A touch panel system includes an electrostatic capacitance type touch panel including a drive electrode, a position detection electrode, and a pressing force detection electrode; and a controller configured to provide a drive signal to the drive electrode and acquire a position signal value from the position detection electrode and a pressing force signal value from the pressing force detection electrode. The controller detects a position of a pointer based on the position signal value, and acquires a pressing force generated by the pointer based on a rate of change of a smoothed value of the pressing force value based on the pressing force signal value.

摘要： The present invention simultaneously detects a location of an electric conductor and pressure that is applied by the electric conductor. A touch panel (1) includes a plurality of sensing electrodes (2) that extend in a first direction for detecting a touch location based on an electrostatic capacitance; and pressure detecting electrodes (4) each of which extends in the first direction and is provided between adjacent two of the plurality of sensing electrodes (2). Each of the pressure detecting electrodes (4) has a width smaller than that of each of the sensing electrodes (2) and has resistance that changes in response to applied pressure.
