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.
