PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

PURPOSE: A pixel and an organic light emitting display device using the same are provided to display a uniform image regardless of the difference of a threshold voltage by compensating for the threshold voltage of a driving transistor. CONSTITUTION: A pixel and an organic electroluminescent display device using the same include an organic light-emitting diode(OLED), transistors(M1-M5), and a pixel(110). An anode electrode is connected to a first power source and a cathode electrode is connected to a second power source. The first transistor is connected between the anode electrode of the organic light-emitting diode and the first power source and a gate electrode is connected to the first node. A second transistor is connected between the first node(N1) and the first power source and the gate electrode is connected to a scanning line. The pixel comprises a capacitor(C1) connected between a connection node of the first and fourth transistor and the second node.
