Patent ID: 7903052

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 certain section; an active device commonly connected to the at least two light emitting elements to drive the at least two light emitting elements; and a power source control part connected to the active device to transmit power source signals for the at least two light emitting elements to the active device, wherein the active device sequentially controls emission of the at least two light emitting elements in the certain section per a certain period of time in response to the power source signals transmitted through the power source control part, and the at least two light emitting elements are sequentially emitted per the certain period of time to realize the certain colors in the certain section, wherein the active device comprises 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, and a plurality of driving devices for transmitting driving signals to the at least two light emitting elements in response to the data signals and the power source signals, and wherein the plurality of driving devices of the active device are commonly connected to the switching device of the active device.
