Emission Driver and Organic Light Emitting Display Using the same

The present invention relates to a light emitting control line driver to freely control the width of the emission control signal. Emission control line drive unit of the present invention is connected to the odd-numbered emission control lines are respectively connected to odd-numbered stages and the even-numbered emission control lines are driven by a first clock signal, the second even-numbered driven by the second clock signal comprises the stages, each of the stages is transferred from the single-stage receive or supply the emission control signal is inverted light emitting control signal, and a first driving unit for generating an emission control signal when supplied a start signal and an inverted start signal from the outside, the prior receive or supply a light emission control signal and a reverse light emission control signal of the stage the stage, received from an external supplying the start signal and the inverted start signal and a second driving unit for generating a reverse light emission control signal.
