Abstract
The present exemplary embodiments relate to measurement of a characteristic of a driving transistor and sensing driving therefor. Provided are a data driver, an organic light emitting display panel, an organic light emitting display device, and a driving method thereof which are capable of measuring characteristics of a driving transistor even at a data voltage which is not so high within a short sensing time by simultaneously sensing the characteristics of the driving transistors for two or more sub pixels, among a plurality of sub pixels commonly connected to the sensing lines, while measuring characteristics (for example, a threshold voltage or a mobility) of the driving transistor.
