Abstract
A display controller controls changing timing of a waveform of each of gate clock signals (GCKGCK) so that a display driving operation is performed after the lapse of a relatively short time from a starting point of time of a horizontal scanning period in odd-numbered horizontal scanning periods (Ho), and that a display driving operation is performed after the lapse of a relatively long time from a starting point of time of a horizontal scanning period in even-numbered horizontal scanning periods (Ho). A touch panel controller outputs a pulse of a touch drive signal (STD) so that a position detection operation on a touch panel is started in a stable period after an end of the display driving operation in each of the odd-numbered horizontal scanning periods (Ho).
