Organic Light Emitting Display Device and Driving Method Thereof

摘要

PURPOSE: An organic light emitting display device and a driving method thereof are provided to minimize noise by making the emission time of pixels different. CONSTITUTION: A control signal is supplied to a control line(CL) during a threshold voltage compensation period. Third and fourth transistors(M3,M4) are turned on. The voltage of a reference power source(Vref) is supplied to a first node. A second node(N2) and the second electrode of the second transistor are electrically connected. A scan signal is supplied to scanning lines(S1~Sn) during a scan period. The data signal is supplied to the data lines. The lighting control signal is provided to lighting control lines(E1~En) during a threshold voltage compensation period and a scan period.
