Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A sweep signal driver comprising:
a plurality of stages configured to sequentially output emission signals to emission lines, and sequentially output sweep signals to sweep signal lines,
wherein the plurality of stages comprises a kth stage configured to output a kth emission signal to a kth emission line, and output a kth sweep signal to a kth sweep signal line, where k is a natural number, the kth stage comprising:
a first pull-up node;
a second pull-up node;
a third pull-up node;
a node connection circuit between the first pull-up node and the second pull-up node, and between the first pull-up node and the third pull-up node;
a first output circuit configured to output a sweep clock signal of a sweep clock terminal to a first output terminal connected to the kth sweep signal line when the third pull-up node has a gate-on voltage; and
a second output circuit configured to output a gate-on voltage to a second output terminal connected to the kth emission line when the second pull-up node has a gate-on voltage, and

wherein a pulse of the kth sweep signal linearly changes from a gate-off voltage to the gate-on voltage.
