LIGHT EMISSION DRIVE CIRCUIT AND ITS DRIVE CONTROL METHOD AND DISPLAY UNIT AND ITS DISPLAY DRIVE METHOD

摘要

A light emission drive circuit includes an electric charge accumulating section for accumulating electric charges on the basis of a gradation sequence signal designating a luminance gradation sequence. A light emission control section flows a light emission drive current having a current value in accordance with an amount of the electric charges accumulated in the electric charge accumulating section. A writing control section controls a supplying state of the electric charges based on the gradation sequence signal to the electric charge accumulating section on the basis of a first control signal. A voltage control section controls a drive voltage for operating the light emission controlling section on the basis of a second control signal.
