Abstract:
A light emission control driver includes stages, each including: an input circuit controlling voltages of first and second nodes (N1, N2) 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 (N3) based on the voltage of N1 and a second CS; a second main circuit controlling the voltage of N3 based on the voltage of N2; an output circuit controlling output of an emission control signal (ECS) based on the voltages of N2 and N3; 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 N2.
