Abstract
A driver comprises odd-numbered stages configured to be driven by first and second clock signals and even-numbered stages configured to be driven by the second and third clock signals. Each stage is coupled to a corresponding emission control line, and includes a first driver, a second driver, and a third driver. In a first stage, the first and second drivers receive first and second start pulses and output first and second output signals, respectively. In each stage except the first stage, the first and second driver receives first and second output signals of a previous stage and outputs first and second output signals of each stage, respectively. In each stage, a third driver receives the first and second output signals of each stage and outputs an emission control signal to be transmitted to an emission control line coupled to each stage.
