Abstract

An organic light emitting display device includes: a display part comprising a plurality of pixel circuits, a pixel circuit from among the pixel circuits comprising: an organic light emitting diode; and a first transistor, the first transistor comprising a first electrode configured to receive a power source voltage and a second electrode connected to the organic light emitting diode; an initial voltage determiner configured to change a level of an initial voltage using image data of a frame; a sensor configured to apply the initial voltage to the second electrode of the first transistor; and a data driver configured to apply a data voltage to the control electrode of the first transistor.
