Patent ID: 11908419
Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 14:
15. The display device according to claim 12, wherein the first controller includes:
a first transistor controlled by the block signal and configured to output the clock signal;
a second transistor controlled by the group signal and configured to connect the first transistor to the first node; and
a third transistor controlled by a third gate-on voltage supplied through a third power line, and configured to connect a fifth power line supplied with a second gate-off voltage to the first node,
wherein:
the first controller outputs the clock signal to the first node through the first and second transistors when the block signal and the group signal are in the gate-on level, and
the first controller outputs the second gate-off voltage to the first node through the third transistor when at least one of the clock signal, the block signal, and the group signal is in the gate-off level.
