That's right, blue LED panel as backlight is cheaper and more efficient than the expensive Micro LED. High manufacturing cost of Micro LED will significantly reduce Apple's profit and competitiveness in the fierce competitive display market. Our film partners are producing photo luminescent QD LED film with blue LED backlight that uses more than 1 gram of quantum dot in big screen TV. There is a consensus that electro luminescent QD LED display will be out in 2019, there is no doubt our film partners are working on that too, may be our film partners already have electro luminescent QD LED film viable for AMQDLED display, the ultimate future display technology, but why not sell photo luminescent QD LED film first, it uses more quantum dots and QMC will sell more quantum dots for now.
