Abstract
An emission control driver includes: a plurality of stages having: a first circuit portion configured to generate a first control signal at a first node and a second control signal at a second node; a second circuit portion configured to control a voltage level of the first control signal; a third circuit portion configured to generate a third control signal based on the first control signal, the second control signal, and the second clock signal; a first output transistor configured to output a first voltage as the emission control signal in response to the first control signal; and a second output transistor configured to output a second voltage as the emission control signal, and wherein the third circuit portion comprises a first capacitor configured to maintain a substantially constant voltage between both electrodes while each of the plurality of stages outputs the emission control signal.
