Claim 0:
1. An organic light-emitting display device including a display panel including a driving thin film transistor (TFT), comprising:
a sensing unit configured to perform a sensing operation for external compensation of the display panel; and
an analog-digital converter (ADC) configured to perform a conversion operation of converting an analog value held in the sensing unit into a digital value,
wherein the sensing unit comprises:
a basic sensing unit configured to perform a sensing operation on the driving TFT; and
a dummy sensing unit configured to perform 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.
