Abstract
A touch panel control device includes a delay setter that sets a delay amount corresponding to a first gate clock signal for controlling a drive timing of a gate line provided in a display panel, and a touch panel driver that outputs a drive pulse for detecting the touch position to a drive electrode based on the delay amount set by the delay setter, wherein the touch panel driver outputs a signal having a predetermined voltage level to the drive electrode and a reception electrode before outputting the drive pulse to the drive electrode.
