This article is some what confusing as you can see by the comments. It talks about diffusers in one instance then LED phosphor replacement in another. It basically seems to be marketing mumbo jumbo.

The claim of 60% coverage of color is interesting. What colors are left out? Will this create artifacts that make the resulting colors look 'artificial'?

@pixies My understanding is that the quantum dot enhancer does not replace the RGB color filters of a conventional LCD...it enables a "richer" white backlight...that when filtered down produces a broader gamut of reds and greens.

It seems something is missing here. You have a GaN LED light source, then the QDEF serves as color filters, but how do you decide what color to convert to for each pixel?

I would say cleaver use to words with 'zero change in thickness'. The QD's variation in size can act as a color filter but for a homogeneous filtering the size should be nearly same. We can for sure increase the color range but what about the color sharpness? The early adoption of this technology will depend on the marketability.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
