Organic light emitting diode display and method of driving the same

摘要

An OLED display device is provided. The OLED display device may include a first capacitor connected between a data line and a first node, a first transistor connected to the first node and a second node, an OLED connected between a low-level source voltage terminal and a third node, a second transistor connected to the second and third nodes, a driving transistor, and a second capacitor. The driving transistor may have a gate connected to the first node, a drain connected to the second node, and a source connected to a high-level source voltage terminal. One end of the second capacitor may receive a second scan signal, and the other end of the second capacitor may be connected to the second node.
