Organic Light Emitting Display Device and Driving Method of the same

摘要

PURPOSE: An organic electroluminescent display device and a driving method thereof are provided to improve the display quality by improving the stain pattern. CONSTITUTION: A first transistor(S1) transfers the data voltage to a first capacitor. A second transistor(S2) transfers the initial voltage to a second capacitor. A 3rd transistor(S3) is controlled in order to transfer the initial voltage. A fourth transistor(S4) detects the threshold voltage of a driving transistor(DT). A fifth transistor transfers the data voltage to a gate terminal of the driving transistor.
