The QMC type of microLED does not use LED diodes at all!
Hawk, your article http://www.ledinside.com/newsletter/2309 makes the point that new techniques must be devised to 'mass transfer' blue LED chips to supply the backlight for microLED. That is using the old/current tech that has LED diodes on the backplane, and for microLED there would, in their mind, be many more of these chips. In my mind, QMC will develop a blue EL QD film that eliminates LED diodes.

Still, the manufacturing cost of micro-LED-based products on average can be three to four times as much as products based on traditional display technologies, according to LEDinside’s analysis. Therefore, developers of micro-LED displays will have to devise effective cost-cutting (or yield-raising) solutions in chip production and mass transfer.
BUT, as we discovered yesterday from another article posted here, a blue QD electroluminescent film can be screen printed placing the blue QD directly at each 'microLED' pixel group on the film. That is not an LED diode, it is an EL Film, and the cost would be much less than the 'mass transfer' of hundreds of micro LED chip diodes, because no chips are needed.

Roger Chu pointed to mass transfer as the most difficult technology bottleneck that prevents the general production cost of micro-LEDs from going down. “Creating mass transfer solutions requires efforts across different industries including LED, semiconductor devices and the entire display supply chain,” said Chu. “Also, new solutions could lead to different specifications for processing equipment, testing equipment, chip products, raw materials and etc. New specification standards will raise the technology barrier for market entrants. The need for cross-industry collaboration will also prolong the R&D period for developers of micro-LED displays."
All the problems mentioned in that quote are bypassed and the structure of a QMC microLED can be thinner, flexible, brighter, more reliable, easier testing, plentiful common raw materials. R&D time would be greatly reduced and microLED could supplant current technology faster than expected. Another "MARKET ANALYST' that caters to current subscribers (Samsung, probably, for example) rather than do the hard research.
