Abstract
Disclosed is an OLED display device capable of sensing and correcting a progressive bright point defect and a method of driving the same. The OLED display device includes a data driver for supplying an off-driving voltage to a driving transistor for driving a light emitting element in each sub-pixel, and sensing a voltage corresponding to a leakage current of the driving transistor, and a bright point estimator for estimating a progressive bright point of a sub-pixel by comparing a voltage value sensed through the data driver with a reference value, and darkening and correcting the sub-pixel estimated to have the progressive bright point.
