For smartphones, most think that Microled will be too expensive, but by using a electrochromatic Blue QD Film as the backlight for photoluminescent Red and Green, cost savings over Blue LE Diodes and their manufacturing and transfer problems can be accomplished, especially for the smaller size smartphone screen.

QMC makes commercial-ready Blue QD now. There is a big difference between having a sheet of electrochromatic Blue QD as a backlight and having to manufacture Blue QD Leds, and transfer them onto a backplane. The film would give better performance by greater coverage and lower cost by less material, material handling, material transfer and attach.
