摘要： Disclosed are an organic light emitting display device and a display panel thereof, which are capable of performing a recovery driving for recovering a threshold voltage of a driving transistor (DT) to be within a range of compensation for the threshold voltage if the threshold voltage of the driving transistor (DT) deviates from the range of the compensation for the threshold voltage as a driving time of the driving transistor (DT) of a pixel increases.
