Abstract
The present disclosure relates to an organic light emitting display device which is implemented to reduce or suppress the residual image and the flicker. According to an embodiment, a circuit includes an organic light emitting diode disposed between a first node and a first power source, a driving transistor disposed between the first node and a second power source and driving the organic light emitting device, a first transistor transmitting a data signal to the driving transistor, and a first control transistor disposed between the first node and a second node. The first control transistor applies a reverse current to the driving transistor during a first period and holes accumulated on the active layer of the driving transistor are removed during the first period, whereby a current path efficiency is improved.
