Title: TOUCH PANEL DEVICE AND TOUCH PANEL CONTROL METHOD
Abstract:
Provided is a touch panel device that easily sets the tactile sensation resulting from an oscillatory wave of a plurality of piezoelectric elements to match the desires of a user. To achieve same, a tactile sensation pattern table (51) stores a plurality of tactile sensation patterns resulting from the combination of a plurality of parameter values of a phase difference table (54), a frequency table (53), and a voltage table (52). An oscillation drive control unit (18) causes the oscillation of the touch panel (12) by imposing a drive signal on each of a first through third sect of piezoelectric elements on the basis of a parameter value obtained from the voltage table (52), a parameter value obtained from the frequency table (53), and a parameter value obtained from the phase difference table (54) corresponding to a tactile sensation pattern of the tactile sensation pattern table (51).
