The German company BMG MIS (formerly AEG MIS) has developed “Geameleon ”- ChLCDs full color and monochrome in various sizes and resolutions. These ChLCDs can be used in extremely wide temperature applications i.e. for outdoor application. Various update versions can be applied to achieve a reasonable update time even at very low temperatures. Because of its very low power consumption, this technology is highly preferred to be used in self-sustaining applications (solar power applications).
