Claim:
1. A pixel, comprising: an organic light emitting diode (OLED) including a first electrode coupled to a second power source; a first transistor coupled between a data line and a first node; a second transistor including a first electrode, a second electrode and a gate electrode, the second transistor to drive the OLED with a current based on a voltage level of the gate electrode of the second transistor; a third transistor coupled between the first node and the first electrode of the second transistor; a fourth transistor coupled between the gate electrode of the second transistor and an initial power source; a fifth transistor coupled between the second electrode of the second transistor and the gate electrode of the second transistor; a sixth transistor coupled between the first electrode of the second transistor and a first power source; a seventh transistor coupled between the second electrode of the second transistor and the OLED; a first capacitor coupled between the first node and a third power source; and a second capacitor coupled between the gate electrode of the second transistor and the first power source, wherein when the first capacitor is charged with a data signal from the data line, the first transistor is turned on such that the data line is electrically connected to the first node and the third transistor is turned off such that the second transistor is electrically disconnected from the first node.
