Crunch, that is an Excellent infographic on Micro-LED
So good I am posting it again for those that might have skipped it -
Micro LED: Understand the New Display Technology in 3 minutes
The importance of micro-LED has been very underreported.
First, it is uses emissive quantum dots in some kind of electrically conductive silicone or polymer. The QD are electrically stimulated to luminesce, hence they are emissive. Emissive QD must meet higher specifications than photoluminescent QD and so are harder to manufacture and presumably would cost more than previous generations of QD. This cost is offset by their higher brightness requiring less QD for similar applications.
Second, Micro-LED are 100 times smaller than regular LED. This is a manufacturing challenge to effect size reduction. This retooling is expensive, but it is offset in that Micro-LED require much fewer layers and no backlight, lowering overall manufacturing expense over time.
Third, from examples I see in papers, Red, Green AND Blue QD are all a requirement. This is the first application commercially proposed to use Blue QD. While QMC has not announced their being able to make Blue QD, Uniglobe-Kisco said it in a marketing blurb for SID-Displayweek upcoming.
Fourth, while there may be a few QD manufacturers presenting at the Micro-LED Forum in Taiwan, none have announced the ability to manufacture Blue QD, and more importantly, the ability to mass-produce them. What does it take to manufacture Blue QD? Why has it not been done commercially prior to now? First, Blue QD would be the smallest size of any QD Color. Red are the biggest, Green are much smaller, and Blue and UV (if possible) would be smaller still, perhaps under 2nm. It is difficult by batch method to time and temperature something that small which requires precision. An automated process can be duplicated. Second, it might require different materials than currently used which would require new science and understanding, a new paradigm for QD manufacture. It might also require different integration into QD products, which is more than just retooling, it is reconceptualization.
Fifth and finally, Apple is reported to be considering using Micro-LED in next gen smartphones. This is a small size application but represents a quantum leap in display technology that would put Apple way ahead in smartphones.
Hundreds of millions of units would be sold yearly. If this technology is near ready for smartphones, and if it is possible to integrate Micro-LED into large screen displays, it has the potential to quantum-leapfrog Samsung's QLED technology for displays that are less expensive to manufacture with much better detail and brightness.
We know the QD display market is only beginning now. Millions of units today will be hundreds of millions in a few years. What better time to adapt a new technology that is the future?
