Abstract
An organic electro-luminescent display apparatus can compensate for the threshold voltage and voltage drop of the driving transistor. The organic electro-luminescent display apparatus divides and drives an initialization time, thereby improving a contrast ratio. The organic electro-luminescent display apparatus minimizes or reduces the change of a current due to a leakage current by correcting the leakage current corresponding to a data voltage with a fixed power source, thereby improving crosstalk. The organic electro-luminescent display apparatus adjusts the duty of the emission control signal, thereby removing or reducing motion blur.
