Abstract
Discussed is an OLED display device and a method of driving the same. The OLED display device includes first to third transistors, a capacitor, a driving transistor, and an OLED. The first transistor supplies a data voltage to a first node according to a first scan signal. A first electrode of the second transistor is connected to the first node, and a gate of the second transistor is connected to a second electrode of the second transistor. The third transistor initializes a voltage of a second node according to a second scan signal. One end of the capacitor is connected to the second node, and the other end of the capacitor is connected to a third node. A gate of the driving transistor is connected to the second node, and a source of the driving transistor is connected to the third node. The OLED emits light.
