Abstract:
An active-matrix organic light-emitting diode pixel circuit and a driving method for the same are provided to eliminate adverse effects of variation in transistor threshold voltage. However, owing to internal parasitic parameters of transistors, compensation for variation in a threshold voltage is not necessarily fully achieved. Therefore, mura otherwise arising from variation in a threshold voltage and degradation of organic light-emitting diodes is eliminated at an emission stage by an external processor's sensing an anode voltage of the organic light-emitting diodes, calculating an offset value related thereto, and adjusting an originally output data voltage with the offset value.
