Patent ID: 11961480
Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 8:
9. An organic light emitting display apparatus comprising:
a display panel including a display area in which a pixel array is disposed and a non-display area disposed in at least one side of the display area; and
a plurality of stages,
wherein each of the plurality of stages comprises:
a first node controller controlling a voltage of a first node by using first and second clock signals;
a second node controller controlling a voltage of a second node by using the first and second clock signals, an output clock signal, and a start signal;
a third node directly connecting to the first node through a tenth transistor; and
an output buffer unit including a first transistor and a second transistor,
wherein the first transistor outputs a gate low voltage as a scan signal while the second node is activated, and the second transistor outputs the output clock signal as the scan signal while the third node is activated,
wherein the scan driver supplies a scan signal generated through each of the plurality of stages to a plurality of scan lines of the pixel array, and
wherein a rising edge or a falling edge of the output clock signal is synchronized with a falling edge of the first clock signal or a falling edge of the second clock signal.
