Pixel and organic light emitting display using the same

An organic light emitting display comprising:

• a scan driver for supplying scan signals to scan lines, for supplying emission control signals to emission control lines, and for supplying inverted emission control signals to inverted emission control lines;
• 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 a pixel from among the pixels, positioned in an ith (i is a natural number) horizontal line, comprises:
• an organic light emitting diode (OLED) comprising a cathode electrode coupled to a second power source;
• a first transistor comprising a gate electrode coupled to and sharing a voltage of a first node for controlling an amount of current that flows from a first power source coupled to a first electrode of the first transistor, to the second power source via the OLED;
• a second transistor coupled between one of the data lines and the first electrode of the first transistor, and configured to turn on when one of the scan signals is supplied to an ith scan line of the scan lines;
• a third transistor comprising a first electrode coupled to a second electrode of the first transistor, and a second electrode coupled to and sharing a voltage of a second node, and configured to turn on when the one of the scan signals is supplied to the ith scan line;
• a fourth transistor comprising a first electrode coupled to and sharing the voltage of the second nod;
• and a second electrode coupled to an initializing power source, and configured to turn on when another of the scan signals is supplied to an (i-1)th scan line of the scan lines;
• and
• a fifth transistor coupled between the second node and the first node, and configured to electrically connect the first node to the second node when one of the inverted emission control signals is supplied to an ith inverted emission control line of the inverted emission control lines.
