摘要：
Disclosed are a pixel circuit (310) of an organic light emitting diode (OLED) panel (300), a display device and a method of driving an OLED panel. The pixel circuit includes a switching element which is driven by a scan signal input through a scan line sequentially selected from among a plurality of scan lines and transfers a driving current corresponding to brightness data input through a data line, and an OLED which is driven by the driving current transferred through the switching element to emit light. According to an exemplary embodiment of the present invention, since a transistor (QN 31 ) which performs a switching functions arranged in a conventional PMOLED panel structure, problems of brightness unbalance and brightness deterioration occurring due to a sequential driving method of a scan line are solved, and a problem of an existing AMOLED panel structure in that a circuit is complicated is solved.
