Organic light emitting display device and method of driving the same

An organic light emitting display device, comprising:

• pixels connected to scan lines, data lines, and emission control lines and configured 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 driving power source and the pixels or between the second driving power source and the pixels and configured to measure to at least one of current and voltage;
• a controller configured to generate a control signal in response to at least one of the current and the voltage measured by the sensing unit;
• a timing controller configured 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 configured to supply emission control signals to the emission control lines in response to the emission start signals.
