ABSTRACT:
An emission driver for an organic light emitting display device is disclosed. The emission driver includes a plurality of flip-flops, and each flip-flop selectively receives two input signals and inverts a level of a received input signal. Also, each flip-flop transmits the level-inverted signal to an adjacent flip-flop, inverts the level-inverted signal, and transmits the inverted level-inverted signal to the adjacent flip-flop and as an emission control signal. To invert the level of the received input signal, the emission driver includes a level shifter, which includes transistors of the same conductivity type arranged to reduce power consumption.
