摘要:
An organic electroluminescent display device includes an organic light-emitting diode, a first transistor outputting a data voltage by an nth scan signal (n is a natural number), a second transistor providing a current to the organic light-emitting by the data voltage, a capacitor storing the data voltage, and a third transistor supplying the second transistor and the capacitor with a pre-charge voltage by an (n−1)th scan signal, the pre-charge voltage having an opposite polarity to the data voltage.
