Quantum dots are pretty cool, and are just emerging in some TVs. Good to see them in monitors.
They are a way of essentially tuning/filtering the backlight so that you can reproduce colours more accurately. Can let you improve colour without increasing the bandwidth of the source signal - which is cool, given the issues prevalent in 4K and UHD signals.
Combine quantum dots with HDR and the new HEVC codec and we have something that the majority of consumers might actually be able to fit down their last-mile connection!
Obviously we need to see these tested, but I think their pretty neat.
As far as I'm aware, it's just a thin film that you place between the backlight and the screen, so I'm not sure how it would interfere with the pixels themselves. Do correct me if I'm wrong!
This is a neat way to get more out of LED LCD screens (especially with full array backlighting), instead of trying to drive down the cost of OLED.
From what I've just read, quantum dot displays are kind of like OLED displays. But, instead of diodes, the pixels are made up of electroluminescent crystals.
The crystals can hold electrons in sort of the same way a transistor does. Meaning you don't have to be constantly feeding the same amount of power to the pixel to keep it alight. So a still image uses a lot less energy than a moving one.
Play around with the chemistry of the crystals, like Philips and AOC have done, and you can get really colour accurate monitors.
Ahh yes - so these monitors are actually (almost certainly) using a QD film and not the QD-version of OLED that you've just read about. The film sits in front of the backlight and does stuff like enhance blues or reduce yellows that are found in the light - kinda like removing impurities, or boosting deficiencies.
As full QD-LED screens could be made in the same process as OLED, they don't really bring any benefits to the business models currently - as they're too expensive.
With the film approach, which I've heard from those involved is pretty cheap, you can make the argument that it should be integrated into standard equipment.
