Patent ID: 8274455

Claim:
A pixel driving circuit for a display device in which a plurality of gate lines and data lines are arranged, the pixel driving circuit being disposed at an intersection between the gate lines and the data lines, the pixel driving circuit comprising; at least two light emitting elements for emitting certain colors within a period of time; a switching device for transmitting data signals received through one of the data lines in response to scan signals received through one of the gate lines; a driving device connected to the at least two light emitting elements to sequentially transmit driving signals to the at least two light emitting elements in response to the data signals transmitted by the switching device; and a power source control part connected to the at least two light emitting elements to sequentially transmit power source signals, wherein the at least two light emitting elements are sequentially emitted per a sub-period of time in the period of time in response to the power source signals to realize the certain colors in the period of time.
