Claim 6:
7. A control device for controlling a display device, the display device including a plurality of gate lines and a plurality of common electrodes, the display device used for both image display and touch detection, the control device comprising:
a drive circuit that generates a gate signal as at least a sine wave, wherein
the control device outputs the gate signal to the plurality of gate lines,
when a specific frequency at which harmonics need to be restrained and a frequency of the gate signal satisfy a changing condition, the drive circuit generates the gate signal as the sine wave, and,
when the specific frequency and the frequency of the gate signal do not satisfy the changing condition, the drive circuit generates the gate signal as a square wave.
