Abstract
A light-detecting element, an analog-to-digital converter circuit, and a parallel-serial converter circuit are mounted on a substrate, using a thin film transistor, of an active matrix-type display device, and when a circuit is selected by an external chip-select signal, the luminance is adjusted by transmitting a signal of the light-detecting element, converted into digital data, to a luminance control circuit in sync with a clock signal.
