Patent ID: 8379010

Claim:
An image display apparatus comprising: a plurality of pixel circuits, each of which includes a light-emitting device and a drive device that drives the light-emitting device; a power source line connected to the respective pixel circuits; an image signal line that applies an image data potential depending on an emission brightness of the light emitting device to the drive device; and a drive control unit that controls a magnitude and an output timing of a potential applied to the image signal line, and controls a magnitude and an output timing of a potential applied to the power source line, in order to perform an emission control to the respective pixel circuits all at once in all of the plurality of pixel circuits, wherein the drive control unit gradually changes an image data potential of the image signal line from a first potential serving as a reference potential to a second potential serving as a constant potential so as to start the emission of the light-emitting device, wherein the potential applied to the power source line is changed from a third potential to a fourth potential at the time of starting a light-emitting period by the light emitting device, and wherein the time taken for the image data potential of the image signal line to change from the first potential to the second potential is longer than the time taken for the potential applied to the power source line to change from the third potential to the fourth potential.
