Abstract
A light emission apparatus is provided. The apparatus comprises a plurality of pixels that each include a light emission element, and a signal supply unit that supplies to each of the plurality of pixels a signal voltage that accords with inputted image data. Each of the plurality of pixels comprises a first transistor configured to control an amount of current that flows in the light emission element, and a second transistor disposed between a signal line on which the signal voltage is supplied and a gate electrode of the first transistor and, in an on state, write in the gate electrode the signal voltage. The signal supply unit adjusts the signal voltage in accordance with a frame rate.
