Pixel and organic light emitting display device using the same

An organic light emitting display device comprising:

• a scan driver for sequentially supplying scan signals having a width of at least 2H (where “H” represents a horizontal period) to scan lines and for supplying emission control signals to emission control lines arranged in parallel to the scan lines, the scan signals partially overlapping with each other;
• a data driver for supplying data signals to data lines;
• and
• pixels located at crossing regions of the scan lines and the data lines, wherein each of the pixels comprises:
• an organic light emitting diode having a cathode electrode electrically coupled to a second power source;
• a first transistor having a first electrode coupled to a first power source, and located between the first power source and the organic light emitting diode, the first transistor being for controlling an amount of current supplied from the first power source to the organic light emitting diode;
• a second transistor between a gate electrode and a second electrode of the first transistor and configured to be turned on when a corresponding one of the scan signals is supplied to a current scan line of the scan lines, the gate electrode of the first transistor being electrically coupled to a first node;
• a third transistor between a corresponding one of the data lines and a second node and configured to be turned on when a corresponding one of the scan signals is supplied to a subsequent scan line of the scan lines;
• a first capacitor electrically coupled between the gate electrode of the first transistor and the second node;
• a fourth transistor configured to be turned on when a corresponding one of the scan signals is supplied to a previous scan line of the scan lines to supply a first voltage to the gate electrode of the first transistor;
• a fifth transistor for supplying a second voltage to the second node when the corresponding one of the scan signals is supplied to the current scan line;
• and
• a sixth transistor between the second electrode of the first transistor and the organic light emitting diode and configured to be turned off when a corresponding emission control signal of the emission control signals is supplied to a current emission control line of the emission control lines,
• wherein the current scan line is an i-th scan line of the scan lines, the previous scan line is an i−2-th scan line of the scan lines, and the subsequent scan line is an i+3-th scan line of the scan lines, wherein i is a natural number.
