Claim 10:
11. A method for driving an organic light-emitting display device including a display panel including a driving thin film transistor (TFT), the method comprising:
performing, by a sensing unit, a sensing operation for external compensation of the display panel; and
performing, by an ADC, a conversion operation of converting an analog value held in the sensing unit into a digital value,
wherein the performing the sensing operation comprises:
performing, by a basic sensing unit comprised in the sensing unit, a sensing operation on the driving TFT; and
performing, by a dummy sensing unit comprised in the sensing unit, a sensing operation on changes in a gain and an offset of the ADC, and
the basic sensing unit and the dummy sensing unit are in a cascade connection to each other.
