The wheels turn slowly with this kind of thing. They need to do a lot of testing etc to have a good case against Samsung. That all takes time and money.They’ve been using QD tech since 2015. What’s taken so long?
Yes, very possible.Nanoco were the first company that worked out how to synthesise QDs on the multi-kilo scale. It's entirely possible that Samsung's supplier has found an alternative way of doing this that doesn't use Nanoco's protected method and there are plenty of other QD suppliers: in fact, Samsung bought one of them, QD Vision a few years ago: Samsung Acquires Quantum Dot Tech Company QD Vision.
