Abstract
A touch panel controller is equipped with a control unit that outputs a decimation signal to a drive line driving circuit when touch response magnitude data is a designated value or greater, or in other words, when the distance between a touch panel and a stylus pen is closer than a designated value. Thus, it is possible to realize a touch panel system able to moderate the amount of power consumed when synchronizing drive timings between the pen and the touch panel controller that drives the touch panel, and thereby operate with low power consumption.
