PURPOSE: A method of driving an organic electro-luminescence display device are provided to maintain the brightness uniformity of each pixel by charging a storage capacitor with a threshold voltage of the driving transistor. CONSTITUTION: In a method of driving an organic electro-luminescence display device, a low level power supplied to a voltage supply line is charged to a second Node. A switching transistor is turned on by a first scan pulse supplied to the gate line, and black data supplied to a data line are charged to the first node via the switching transistor. A high level power voltage supplied to the voltage supply line is supplied to a driving transistor. A threshold voltage of a driving transistor is charged to the storage capacitance. The data voltage supplied to a data line is supplied by the driving transistor via the switching transistor. |
