The MEMOLED: Active Addressing with Passive Driving

Passive or active matrix driving schemes in large displays are prone to high power consumption and cost, respectively. For signage applications such as large outdoor 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.
