PIXEL CIRCUIT OF DISPLAY PANEL, CONTROLLING METHOD OF THE SAME, AND ORGANIC LIGHT EMITTING DISPLAY COMPRISING SAME

摘要

PURPOSE: A pixel circuit of a display panel, controlling method of the same, and an organic light emitting display comprising same are provided to compensate voltage change in the source electrode of a driving transistor in emission. CONSTITUTION: In a pixel circuit of a display panel, controlling method of the same, an OLED comprises an anode electrode and a cathode electrode an NMOS transistor(M1~M6) comprises a first electrode, a second electrode, and a gate electrode A fist capacitor(C1) is interposed between a second node and a third node. The second capacitor(C2) is connected between the third node and the anode electrode of the OLED. A third capacitor(Cis) is connected between the second node and the first electrode of a sixth NMOS transistor.
