Abstract
A light emitting display including a selection signal unit, an emission control signal unit and a plurality of pixels. The selection signal unit receives a first start signal, generates a first shift signal, generates a selection signal using the first shift signal, and outputs the selection signal. The emission control signal unit receives a clock signal and a second start signal, generates a second shift signal, generates first and second emission control signals using the first and second shift signals, and outputs the emission control signals. At least one of the pixels includes first and second light emitting elements. The first light emitting element is emitted by the first emission control signal in the first field, and the second light emitting element is emitted by the second emission control signal in the second field.
