PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

PURPOSE: A pixel and organic light emitting display device using the same are provided to display a desired image regardless of voltage supplied to an anode electrode. CONSTITUTION: In a pixel and organic light emitting display device using the same, the first electrode of a first transistor(M1) is connected to a first power source. The first transistor controls the amount of current provided to an organic light-emitting diode(OLED). A third transistor(M3) and a storage capacitor(Cst) are connected to a gate electrode and a second between electrode of the first transistor. A second transistor(M2) is connected between the third transistor the first node of the storage capacitor and a data line. The second transistor is turned on at the different time of the third transistor. A fourth transistor(M4) is connected between the gate electrode of the first transistor and a reference voltage source. The fourth transistor and the second transistor are turned on/off at the same time.
