The present invention relates to an active-matrix organic light-emitting diode (AMOLED) compensation pixel circuit. More specifically, it concerns an AMOLED compensation pixel circuit capable of compensating for luminance variations caused not only by area changes due to substrate stretching but also by voltage drops resulting from increased resistance as wiring length increases.
