Abstract

An organic light emitting display device which secures a sufficient compensation time during which a threshold voltage of a driving transistor is compensated by driving a display panel using a simultaneous emission driving method by which a plurality of pixels simultaneously emit light. The organic light emitting display device may reduce a length (or, a time) of a non-emission period by storing a data signal of a current frame into a second capacitor of the pixel in an emission period of a previous frame and by adjusting a voltage at a gate electrode of a driving transistor of the pixel based on a voltage stored in the second capacitor in a data writing period of the current frame.
