    Abstract: A display apparatus includes: a plurality of pixels arranged in a row-column configuration and divided into a plurality of units each including a plurality of rows; a plurality of scanning signal lines configured to select one row from the pixels; a plurality of pixel signal lines configured to supply pixel signals to the one row; a control circuit configured to output an image signal in which the pixel signals are time-division multiplexed and a plurality of separation control signals for separating the pixel signals from the image signal; and a separation circuit including signal lines and configured to separate the pixel signals from the image signal and output the pixel signals to the pixel signal lines based on the separation control signals. The control circuit switches ends to be supplied with the separation control signals between first ends and second ends of the signal lines in each unit.

    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 capable of suppressing the display quality deterioration is provided even if an optically transparent nondisplay area is formed inside the display area of the display panel of the display device. The display device comprises a display panel including signal lines, scanning lines, and pixels that are connected to the signal lines and scanning lines and surrounded by the signal lines and scanning lines. The display panel includes a display area and an optically transparent nondisplay area inside the display area, and a drive circuit for driving the signal lines. The drive circuit includes at least one of a first drive scheme wherein drive voltages are set smaller as distances between adjacent signal lines corresponding to the drive circuit are shorter, a second drive scheme in which the rising speed of drive waveforms are set smaller as distances between adjacent signal lines corresponding to the drive circuit are shorter, and a third drive scheme in which drive times are set longer as distances between adjacent signal lines corresponding to the drive circuit are shorter.
