The driver IC generates a common voltage to be applied to a common electrode of pixels of a display panel, and generates a high level of a pulse voltage used for driving, by pulses, drive electrodes of a touch panel with its low level set at the common voltage based on data held by a memory region for holding voltage-designating data of the common voltage and amplitude-designating data of the pulse voltage. In addition, the driver IC outputs the common voltage to drive terminals in synchronization with the action timing of the display panel, and outputs a pulse voltage having an amplitude of the high level with respect to the common voltage to the drive terminals in synchronization with the action timing of a touch panel. |
