Emission driver and display device including the same

A display apparatus, comprising:

• a display panel including a pixel which includes an organic light emitting diode and an emission control transistor to drive the organic light emitting diode;
• a timing controller to generate a first clock signal, a second clock signal delayed from the first clock signal, a first dimming clock signal, and a second dimming clock signal delayed from the first dimming clock signal;
• an emission driver to output an emission control signal to the emission control transistor, control a rising period of the emission control signal based on the first and second clock signals, and control a falling period of the emission control signal based on the first and second dimming clock signals, wherein the emission driver includes a plurality of circuit stages and where each of the circuit stages includes:
• a first signal generator to generate a first node signal of a first node and a second node signal of a second node based on a carry signal and a second clock signal;
• a second signal generator to generate a first clock signal delayed from the second clock signal and a third node signal of a third node based on the first and second node signals;
• a pull-up circuit to pull up an emission control signal to a first driving voltage based on the third node signal;
• a pull-up controller to control the signal of the third node based on a fourth node signal of a fourth node;
• a pull-down circuit to pull down the emission control signal to a second driving voltage lower than the first driving voltage based on the fourth node signal;
• and
• a first pull-down controller to control the fourth node signal based on a first dimming clock signal and a second dimming clock signal delayed from the first dimming clock signal.
