Abstract: According to an aspect, a display device includes: a substrate that has a display area; pixels that are provided in the display area and are arranged in a first direction and a second direction intersecting the first direction; gate lines that extend in the first direction and are arranged in the second direction; and a first gate driver and a second gate driver that are configured to supply gate drive signals to the gate lines. The first and second gate drivers are each provided along the second direction and are arranged in the first direction. The first and second gate drivers are configured to: sequentially scan the gate lines in a first area of the display area; and simultaneously scan more than one of the gate lines that are adjacent to one another in the second direction in a second area different from the first area of the display area.

Abstract: A display device includes: pixels arranged in a display region; photodiodes provided in two or more of the pixels, respectively; a shift register circuit configured to sequentially output an output signal to the pixels and the photodiodes; a switching circuit configured to switch coupling between the shift register circuit and the pixels, and coupling between the shift register circuit and the photodiodes; and a control circuit configured to control a display period for display by the pixels and a detection period for detection by the photodiodes in a time division manner. The control circuit is configured to sequentially output a gate drive signal to the pixels by an operation of the shift register circuit and the switching circuit in the display period, and sequentially output a sensor control signal to the photodiodes by an operation of the shift register circuit and the switching circuit in the detection 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.
