MacObserver excerpts:
Quantum Dot 4KTVs actually use the QDs to produce the required backlighting for LCD panels, and those TVs are, in principle, still LCD displays. The quality of the backlighting from QDs is superior to that from white LEDs in terms of brightness and color gamut. Again, this is great for HDR technology in TVs in that respect, but not so great for TV black levels. QDs are stable and, like LEDs, have a long life.
There is no reason, in principle, that Quantum Dots couldn’t be used for iPads and iPhones, and there are some other products now on the market that use QDs. Paul Gagnon, from IHS, told me:_______ "
I think there are maybe only a handful of [small] devices that use Quantum Dots. I think that’s because it’s a relatively new technology and the implementation is still being worked out. Also, when you think about working on the color purity, that’s more critical in the entertainment space, as in television, than in a mobile display. So maybe manufacturers have thought it was not worthwhile putting the investment into Quantum Dots for small displays."........................
It’s important to remember that there are a myriad of engineering trades when a company selects a display technology: design maturity, cost, the ability to manufacture at the desired scale in numbers and size, power consumption, thickness (for small devices), brightness in daylight conditions (or not), color gamut, longevity of the material, and suitability for specific product designs.
That’s why you’ll see some products like 4KTVs focusing at first on certain technologies while small, personal devices may use another. In time, as technology develops in factors such as applicability, cost and manufacturability, you’ll see a company transition to a different technology or, perhaps, invoke multiple different designs at different price points."
