Pixel and organic light emitting display device using the same

An organic light emitting display device, comprising:

• a scan driver sequentially supplying scan signals to scan lines so that transistors receiving the scan signals are turned on when the scan signals are supplied, and sequentially supplying light emitting control signals to light emitting control lines so that transistors receiving the light emitting control signals are turned off when the light emitting control signals are supplied;
• a data driver supplying data signals to the data lines when the scan signals are supplied;
• and
• pixels coupled to respective scan lines and data lines, wherein the pixels each include:
• an organic light emitting diode;
• a second transistor configured to control a connection between a first power source and the organic light emitting diode, the second transistor having a gate electrode and controlling an amount of current supplied from the first power source to the organic light emitting diode in correspondence with a voltage at the gate electrode;
• a first transistor configured to control a connection between the gate electrode of the second transistor and a data line, the first transistor having a gate electrode coupled to a scan line;
• a third transistor configured to control a connection between the organic light emitting diode and a second electrode of the second transistor, the third transistor having a gate electrode coupled to a light emitting control line;
• a first capacitor having a first electrode coupled to the gate electrode of the second transistor and having a second electrode coupled to a first electrode of the second transistor;
• and
• a second capacitor having a first electrode coupled to the gate electrode of the second transistor, the second capacitor controlling a voltage of the gate electrode of the second transistor in correspondence with a voltage variation of the organic light emitting diode.
