Patent ID: 7561124

Claim:
A pixel circuit of a display device for realizing a certain color during a display period of time comprising: at least two light emitting elements between a first constant voltage source and a second constant voltage source, each said light emitting element for emitting a corresponding one of colors during the display period of time; and an active element commonly connected to the at least two light emitting elements to drive the at least two light emitting elements, the active element comprising a driving transistor coupled between the first constant voltage source and the at least two light emitting elements, wherein the active element time-divisionally drives the at least two light emitting elements during the display period of time, such that one said light emitting element emits the corresponding one of the colors per a sub display period of time, and wherein 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.
