Luminance controlling unit, light-emitting unit, and method of controlling luminance

Abstract

A luminance controlling unit includes a luminance controller that controls luminance of a pixel array. The pixel array includes pixels each including a current-driven self-luminescent element. The luminescent controller sets, on the basis of an image signal corresponding to a frame image, a threshold that is directed to detection of a maximum signal level of the image signal, and performs dynamic control of a potential difference between a first voltage and a second voltage on the basis of the maximum signal level detected with reference to the set threshold. The first voltage is outputted from a first voltage source adjacent to an anode of the self-luminescent element, and the second voltage is outputted from a second voltage source adjacent to a cathode of the self-luminescent element.
