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.

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 driven in a first drive mode for displaying images of a frame in a first frame period and a second drive mode for displaying images of a frame in a second frame period longer than the first frame period is provided. The display device includes a display panel configured to perform display operation for displaying an image based on a pixel signal and a driver configured to switch a drive mode between the first drive mode and the second drive mode. When a switch signal is received while the display device is driven in the second drive mode, the driver is configured to shorten the second frame period and switch the second drive mode to the first drive mode.
