Pixel and organic light emitting display using the same

An organic light emitting display, comprising:

• pixels positioned in regions divided by scan lines and data lines;
• a scan driver for supplying scan signals to the scan lines and for supplying an emission control signal to an emission control line commonly coupled to the pixels;
• a data driver for supplying data signals to the data lines in synchronization with the scan signals;
• and
• a control driver for supplying a first control signal to a first control line commonly coupled to the pixels and for supplying a second control signal to a second control line commonly coupled to the pixels,
• wherein each of the pixels positioned in an ith (i is a natural number) horizontal line comprises:
• an organic light emitting diode (OLED);
• a first transistor for controlling an amount of current supplied from a first power supply coupled to a first electrode thereof to the OLED to correspond to a voltage applied to a first node;
• a second transistor coupled between a data line and a second node and turned on when a scan signal is supplied to an ith scan line;
• a third transistor coupled between the first node and the second node and turned on when the second control signal is supplied;
• a first capacitor coupled between the second node and a fixed voltage source;
• and
• a second capacitor and a third capacitor serially coupled between the first node and the first power supply.
