Tiny, easy-to-produce particles, called quantum dots, may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors and medical imaging tools. Although quantum dots have begun to break into the consumer market – in the form of quantum dot TVs – they have been hampered by long-standing uncertainties about their quality. Now, a new measurement technique developed by researchers at Stanford University may finally dissolve those doubts.
[...] The researchers focused on how efficiently quantum dots reemit the light they absorb, one telltale measure of semiconductor quality. While previous attempts to figure out quantum dot efficiency hinted at high performance, this is the first measurement method to confidently show they could compete with single crystals.
[...] “These materials are so efficient that existing measurements were not capable of quantifying just how good they are. This is a giant leap forward,” said Alivisatos. “It may someday enable applications that require materials with luminescence efficiency well above 99 percent, most of which haven’t been invented yet.”

Well, they have to stand by their principals.

I've been interested in the tech since they first started experimenting with it. See this 2006 article: https://www.technologyreview.com/s/405755/nanocrystal-displays/ [technologyreview.com]
The current implementation of "Quantum Dot" technology is still using the old tried and true method of backlights for displays. Nanocrystal Displays are capable of providing their own light.
