Patent ID: 8629816

Claim:
An emission control driver including a plurality of stages adapted to receive voltages from a first power source and a second power source and to generate emission control signals, wherein each of the stages comprises: a first signal processing unit to generate a first output signal based on an input signal, a clock signal, a inverted input signal, the first power source, and the second power source, the first output signal being supplied at a first node of the first signal processing unit; a second signal processing unit to output an emission control signal based on the first output signal and the input signal, the emission control signal corresponding to an inverse of the first output signal; a third signal processing unit to transmit a voltage of the first power source or the second power source to the first signal processing unit based on the emission control signal, a inverted clock signal, and an inverted emission control signal when a first path, between the first power source and the first node, and a second path, between the second power source and the first node, are blocked by the clock signal, the inverted emission control signal corresponding to an inverse of the emission control signal; and a fourth signal processing unit to output the inverted emission control signal based on the emission control signal and the first output signal, wherein the second signal processing unit is coupled between the first signal processing unit and the third signal processing unit.
