ORGANIC LIGHT EMITTING DIODE DISPLAY AND DRIVING METHOD THEREOF

摘要

An OLED display device and a driving method thereof are provided to minimize image sticking by generating a black gray scale voltage and a real data voltage to be supplied to a gate of driving thin film transistors symmetrically with respect to a reference voltage. An OLED(Organic Light Emitting Diode) display device includes an OLED element(OLED), a driving element(pT2), and a data driver. The OLED element is emitted by a current. The driving element drives the OLED element according to a gate voltage applied to a gate electrode thereof. The data driver supplies a symmetric inverse voltage to a data voltage with respect to the data voltage and a reference voltage to a gate electrode of the driving element.
