Abstract: A display device with a touch detection function includes a substrate, pixel electrodes arranged in a matrix in a display region on a plane parallel to the substrate, a display function layer having a function to display the image in the display region, drive electrodes provided facing the pixel electrodes, touch detection electrodes that form electrostatic capacitance between there and the drive electrodes, a control unit that generates a control signal to switch between a display operation period for applying a display signal between the pixel and drive electrodes and a display stop period for stopping the display operation. The control unit generates first and second control signals respectively having a first frequency and a second frequency that is different from the first frequency, and has first and second operation modes respectively including a period controlled by the first control signal and a period controlled by the second control signal.

Abstract: According to one embodiment, a display device includes a display unit and a driver unit. The driver unit includes a display drive unit, a power supply unit and a control unit. The control unit instructs a display period in which the image is displayed in the display unit and a non-display period in which the image is not displayed to the display drive unit, and instructs mitigation driving which mitigates a difference in an electrical load of the display drive unit between the display period and the non-display period to the power supply unit in the non-display period.
