Abstract
An organic light emitting display device includes pixels connected to scan lines, data lines, and emission control lines to emit light components in response to amounts of current that flow from a first driving power source to a second driving power source, a sensing unit connected between the first or second driving power source and the pixels to measure to at least one of current and voltage, a controller to sense a control signal in response to at least one of the current and the voltage measured by the sensing unit, a timing controller to supply a plurality of emission start signals with different widths in a one frame period in response to the control signal when the organic light emitting display device is driven at a low frequency, and an emission driver to supply emission control signals to the emission control lines in response to the emission start signals.
