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 (20) for supplying an off-driving voltage to a driving transistor (DT) for driving a light emitting element in each sub-pixel (SP), and sensing a voltage corresponding to a leakage current of the driving transistor (DT), and a bright point estimator (50) for estimating a progressive bright point of a sub-pixel (SP) by comparing a voltage value sensed through the data driver (DT) with a reference value, and darkening and correcting the sub-pixel (SP) estimated to have the progressive bright point.
