ABSTRACT:
A drive unit which can prevent the decrease of the luminance of a self-luminous device due to degradation or a change is electric characteristic thereof. The drive unit has a semiconductor device having an electric characteristic almost the same as the that of the self-luminous device, and drives the semiconductor device in accordance with the frequency of light emission of the self-luminous device. The device generates a characteristic change detection signal indicating the degree of a change in an electric characteristic of the semiconductor device, and supplies the self-luminous device with a drive signal having a current level or a voltage level based on the characteristic change detection signal.
