Patent ID: 8803770

Claim:
A pixel comprising: an organic light emitting diode connected between a first power supply and a second power supply; a first transistor connected between the first power supply and the organic light emitting diode, the first transistor including a gate electrode connected to a first node; a second transistor connected between a first electrode of the first transistor connected to the first power supply and a data line, the second transistor including a gate electrode connected to a current scanning line; a third transistor connected between a second electrode of the first transistor connected to the organic light emitting diode and the first node, the third transistor including a gate electrode connected to the current scanning line; a fourth transistor connected between the second electrode of the first transistor and the organic light emitting diode, the fourth transistor including a gate electrode connected to a light emitting control line and is turned on by a light emitting control signal supplied to the light emitting control line during a first period of an initialization period, wherein the first period and the initialization period start when a previous scanning signal supplied to the previous scanning line changes state and the fourth transistor is on, and is turned off by the light emitting control signal during a second period of the initialization period following the first period of the initialization period; a fifth transistor connected between the second power supply or a third power supply that is an initialization power supply and the first node, the fifth transistor including a gate electrode connected to a previous scanning line; a sixth transistor directly connected between the second power supply or the third power supply and the fourth transistor, the sixth transistor including a gate electrode connected to the previous scanning line; a storage capacitor connected between the first power supply and the first node; and a seventh transistor connected between the first electrode of the first transistor and the first power supply, the seventh transistor including a gate electrode connected to the light emitting control line.
