Hawk, the first part of the first article, https://www.photonics.com/Article.aspx?AID=62068 has an illustration of an EL backlight on the left side. It shows that instead of blue LED diodes (as on the right side illustration). Blue QD film can be patterned by screen printing for where its needed on the film behind the red and green QD that it will illuminate. This is very cost effective vs diodes. Quantum Materials has Blue QD and I look forward to it being incorporated into thin-film true LED products, including microLED.

Pet Peeve: The article, which seems to promote flourescent proteins for bio-displays does not mention cadmium-free quantum dots as the successor to cadmium QD, and the near universal rejection of Cd QD in the marketplace.
Instead, it speaks of Cd QD as a problem yet to be overcome. Well, maybe that is true of Nanosys, but not Quantum Materials, which has published their high efficiency Cd-Free QD info.

Pet Peeve #2: I have a Google Alert for Quantum Dots and every day someone is promoting an expensive QD Market Report that still includes QD Vision, often in the title. Get a Clue! QD Vision has been gone for almost a year now. Another reason these reports are old and outdated is because Quantum Materials is hardly mentioned as a QD manufacturer.
