ABSTRACT:
A pixel circuit of display device for realizing a certain color during a display period of time comprising. The pixel circuit includes at least two light emitting elements, each said light emitting element for emitting a corresponding one of colors during the display period of time. An active element is commonly connected to the at least two light emitting elements to drive the at least two light emitting elements in response to at least one emission control signal. The active element time-divisionally drives the at least two light emitting elements using the at least one emission control signal during the display period of time per a sub display period of time. The at least two light emitting elements realize the certain color in the display period of time by time-divisionally emitting the corresponding ones of the colors, one of the corresponding ones of the colors being emitted per the sub display period of time.
