Abstract
An organic light emitting display device includes a display panel including a plurality of sub-pixels, each sub-pixel having an organic light emitting diode and a driving transistor to drive the organic light emitting diode; a sensing circuit configured to output sensing data for feature values of the organic light emitting diode or the driving transistor of each sub-pixel; a humidity sensor configured to sense humidity at an edge of the display panel; and a controller configured to compare sense humidity sensed by the humidity sensor with a predetermined critical humidity, and control compensation for variance of the feature values using the sensing data or previously stored reference data, depending on a comparison result.
