Admittedly, this unusual memory requires an internal lightsource, but the amount of illumination required is tiny and consumes less power than the logic circuits that are used to read data in and out.
This technology also increases the light-source lifetime to 20, 000 hours in ExtremeECO mode and enables as much as 90% power savings, helping to reduce TCO over its life, thus positioning the K750 as one of the most environmental friendly projectors.
