Emission control line drivers, organic light emitting display devices using the same and methods of controlling a width of an emission control signal

An organic light emitting display device, comprising:

• a scan driver adapted to sequentially supply a scan signal to scan lines;
• a data driver adapted to supply a respective data signal to data lines;
• an emission control line driver adapted to supply a respective emission control signal to emission control lines;
• and
• pixels positioned at intersection portions of the scan lines, the emission control lines, and the data lines, the emission control line driver, including:
• even-numbered stages that are connected to even-numbered emission control lines, respectively, and are driven by a first clock signal;
• and
• odd-numbered stages that are connected to odd-numbered emission control lines, respectively, and are driven by a second clock signal, wherein each of the stages includes,
• an input unit adapted to receive a control signal and an inverted control signal output from a previous one of the even and odd numbered stages or from an external source, the input unit being adapted to control voltages of a first node and a second node;
• a first output unit adapted to generate an emission control signal based on the voltages of the first node and the second node;
• and
• a second output unit adapted to generate an inverted emission control signal based on the voltages of the first node and the second node.

A method for adjusting a width of an emission control signal, comprising:

• supplying a first clock signal to even-numbered stages of an emission control line driver, the even-numbered stages being connected to even-numbered emission control lines of a panel, respectively,
• supplying a second clock signal to odd-numbered stages of the emission control line driver, the odd-numbered stages being connected to odd-numbered emission control lines, respectively,
• wherein each of the even and the odd numbered stages includes an input unit, a first output unit and a second output unit, and driving each of the even and odd numbered stages includes:
• supplying a control signal and an inverted control signal output from a previous one of the even and the odd numbered stages or from an external source to the input unit, the input unit being adapted to control voltages of a first node and a second node;
• generating and outputting from the first output unit an emission control signal based on the voltages of the first node and the second node and output;
• and
• generating and outputting from the second output unit an inverted emission control signal based on the voltages of the first node and the second node.
