No, I believe the two are quite different. From a non-technical standpoint, QD technology is based on "semiconductor nanocrystal technology", or microscopic particles that emit light at specific wavelengths depending on their size. This allows QD-enabled displays to emit pure, accurate colours within a very narrow bandwidth and minimal waste of energy. It's essentially a layer that sits on top of the LEDs. Blue light passes through, is "energised" to specific wavelengths (RGB) and bounces off the light guide plate and out the top just like a regular LCD.

For colour purity and range, the more specific the wavelength, the better. That's why BRAVIA TVs with Triluminos look great. Many LCD TVs offer a colour gamut that only achieves 60-70% of NTSC standard. Tune this layer of nanocrystals right and you can get 100% of the standard with extreme accuracy.

What makes QD unique is that you get the best of both worlds: excellent CRI without the manufacturing cost/performance tradeoff typical of other lighting tech. OLED is expensive and difficult to manufacture on a large panel. QD offers similar benefits but at a lower cost.

Sony is unlikely to be the only manufacturer using QD technology for long. I believe Sony licensed patents from QD Vision, but Apple is conducting their own research in QDs. Last December Apple filed patents related to QD tech and again earlier this month. Phosphor-based LEDs may just be Sony's way of staying one step ahead.

As mentioned earlier, Xperia's phosphor-based LED tech appears quite different from a colour reproduction standpoint. I'm not even certain you can combine true Triluminos QD-based tech with the Live Colour phosphor-based LED tech. QDs passes the (normally) blue LED light through a layer of nanocrystals, which energises the wavelength to emit different colours. Phosphor is a material you coat the LEDs directly, or several layers (red and green in Xperia's case), which broadens the emitted spectrum.

Both appear to attain similar goals: purer, vivid colours with great accuracy and a very wide gamut. Yet from what information is publicly available, they achieve this through different processes. It could be possible to have both phosphor coated LEDs that then pass through a QD nanocrystal layer. But why? This would increase your manufacturing costs for a diminishing return. Logically you would chose one or the other depending on the panel.

It raises the suspicion that the Triluminos tech in Xperia devices is indeed a software-based enhancement. Conversely, it is the Live Colour enhancement on BRAVIA that is an algorithm powered by an image processor. Since BRAVIA TVs are much bigger and panel thinness isn't a priority, QD tech may be a better fit. For smaller panels (10.1 inch and below), phosphor-based LEDs may be financially feasible.

Note that my own Sony VAIO Pro (13 inch) has Triluminos, but no mention of Live Colour. Thanks to the quality IPS panel, it too is a fantastic display. Long live VAIO.


@Goldenface

The Xperia Z Ultra has a great display, but as far as I can determine it does not employ this phosphor-based LED technology. Certainly not in the same way that the XZ2 and Tablet Z2 does on a hardware level. The XZU White Papers made no mention of it, and given Sony's tendency to advertise technology trademarks (X-Reality, ClearAudio+ etc), it would be unusual if it did.

The XZU's great screen likely comes come down to a superb IPS panel, unlike the XZ1 which was rumoured to use a Vertical Alignment (VA) LCD. Combined with the Triluminos colour enhancement - be it software (likely) or hardware based - and a large viewing area and you get a fantastic display.

More from Zomg
Android |OT3| This thread is incompatible with all of your devices.

This sounds interesting

I was actually more interested in the quite high number of devices getting Android 4.4. Even T, TX, TL and V, late 2012 flagships... Hopefully the early Z line (ZL, ZR, Z, Tablet Z) will have a quite long update history.

Quad Speakers ? Cool !!

Why you don't create the new Z2 tablet thread ?

maybe if sony slapped a small (2"-3") e-ink display at the back of the device for viewing messages and notifications, it would have appeared a little more exciting.

or a low resolution amoled strip just for viewing notifications.

they can make these back panel displays have the same color as the rest of the back not to alter the design.

it will be a better power saving method compared to the galaxy s5's "monochromizing" to save power.

It has been made already now.

I'd said it be for and id say it again Why Only 16GB Internal Memory??? In The Flagship Z2! Again This is The only thing Stopping me Buying it. When will it Happen SONY? in the Z10??

@Ardian:
Wasn't there something exceptional about the Z2 that you couldn't tell us before the announcement?
I'm just curious, what was it?
