Passive or active matrix driving schemes in large displays are prone to high power consumption and cost, respectively. For signage applications such as large out-door displays with low refresh rates there is as yet no technological solution. Here the MEMOLED solution, an organic light-emitting diode with an integrated ferroelectric memory, is presented. Programmability of the integrated memory allows active addressing of the OLED in a passive matrix geometry. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
