Organic light emitting display device and method of driving the same

An organic light emitting display device comprising:

• a scan driver for supplying a first scan signal to a first scan line during a first period of a horizontal period, supplying a second scan signal to a second scan line during a second period of the horizontal period, and supplying a light-emitting control signal to light-emitting control lines during the horizontal period;
• a data driver for supplying data signals to data lines during the second period;
• a current sinker coupled to the data lines for sinking a first current;
• and pixels coupled to the first scan line, the second scan line, the light-emitting control lines and the data lines, wherein
• each of the pixels on an i-th horizontal line, wherein i is an integer greater than or equal to 1, comprises:
• an organic light emitting diode;
• a fourth transistor for controlling an amount of current that flows into a second power source via the organic light emitting diode from a first power source;
• a first transistor coupled to a gate electrode of the fourth transistor and directly coupled to a data line of the data lines, and configured to turn on when the second scan signal is supplied to the second scan line;
• a first capacitor coupled between the gate electrode of the fourth transistor and the first power source;
• a second capacitor coupled between the gate electrode of the fourth transistor and the first transistor;
• a second transistor directly coupled between the gate electrode of the fourth transistor and the data line, and configured to turn on when the first scan signal is supplied to the first scan line;
• a third transistor directly coupled between a second electrode of the fourth transistor and the data line, and configured to turn on when the first scan signal is supplied to the first scan line;
• and
• a fifth transistor coupled between an anode electrode of the organic light emitting diode and a common terminal of the first transistor and the second capacitor, and configured to turn on when the first scan signal is supplied to the first scan line.
