Quantsuff emailed us a link about a new material summarized at Newscientist.com. I have a few thoughts that I’d like to add.
The stuff should be great for illumination. But I have doubts about its use for display purposes. Displays have millions of very small pixels. If one or a few get contaminated with dust or dirt, they will not light, and the display will have a bad dark spot on it. Displays are made in a dust free environment, and paper is a natural carrier of dust. I doubt it could be kept clean enough to be dust free.
