Optics

An area of electronics in which nanotechnology can make a significant difference is in optics; specifically displays and lighting.

It is true that displays have been becoming lighter and of a much higher standard in recent years, but the limits of current technology are fast being reached. Displays are still not very portable, and usually take up a lot of space. Imagine if a crystal-clear display existed that could be rolled up or folded away when not in use? Or a lightbulb that wasted no energy and saved the user vast amounts of money? Traditional light bulbs waste about 90% of their electricity use by turning it into heat.
