Abstract
A light emission control driver includes stages, each including: an input circuit controlling voltages of first and second nodes (N, N) based on a first clock signal (CS) and one of a start signal and a carry signal; a first main circuit controlling a voltage of a third node (N) based on the voltage of Nand a second CS; a second main circuit controlling the voltage of Nbased on the voltage of N; an output circuit controlling output of an emission control signal (ECS) based on the voltages of Nand N; a first auxiliary circuit controlling a low level output of the ECS from a first low level to a second low level based on the second CS; and a second auxiliary circuit controlling the low level output in a single step from a high level to the second low level based on the voltage of N
