Sony Crystal Led = Quantum Dot Led? Very Likely!
I've been closely following the Sony Crystal LED since it was announced. And I found few articles in the internet that if you try to connect the dots would strongly suggest that Sony has been readying to release a QUANTUM DOT DISPLAY.
First, a statement from Stringer November last year.
According to the Sony chief executive, who spoke yesterday with The Wall Street Journal, his company has a "tremendous amount of research and development going into a different kind of TV set." Stringer declined to provide details on what his company's television might offer.
Sony Crystal LED is semiconductor based just like quantum dot. All the qualities of quantum dot display is present in the Sony Crystal LED display except perhaps the supposed 10x brightness of quantum dots.
Nanoco, a british company which makes quantum dot, has been supplying a major electronic company with their cadmium-free quantum dots since April last year. Below is an article stating Nanoco's delivery of red cadmium-free quantum dots to a major Japanese corporation. April 2011
01/04/2011 "Nanoco Group plc (AIM: NANO), a world leader in the development and manufacture of cadmium-free quantum dots, announces that it has successfully produced the 1kg batch of red cadmium-free quantum dots (CFQD™) specified by a major Japanese corporation, which triggers a US$2 million payment to Nanoco by the corporation."
Nanoco successfully delivered green quantum dots to a major Japanese corporation.
31/01/2012 Nanoco Group plc(AIM: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other nanomaterials, announces that it has achieved the performance milestone for green quantum dots being developed in its supply and licence agreement with a major Japanese corporation, triggering a US$1 million payment.
CES. Sony showed that they are working on a semiconductor based display and their calling it Crystal LED. They are the only company that has shown so far anything that resembles a quantum dot display.
Nanoco signed a commercial joint development agreement with a major electronics company in Asia.

Nanoco Group plc (AIM: NANO), a world leader in the development and manufacture of cadmium-free quantum dots and other nanomaterials, announces that it has signed a commercial joint development agreement (JDA) with a major electronics company in Asia in connection with the use of the Company's cadmium-free quantum dots (CFQD™) in the electronics company's display products.
(January) Sony: Crystal Led will be available later this year.
(December 2011) Nanoco: Quantum Led TVs available by the end of 2012.
Sony execs told the Wall Street Journal that the Crystal LED Display technology is more stable than OLED, so there should be fewer manufacturing errors, which presumably could lower the price for the sets. While there’s no public timeline for when commercial sets using the new technology would be available, a Sony exec told the Journal that units will be available later this year.
http://www.digitaltrends.com/home-th...-soon-as-2012/But it could slip to 2013.
The British company Nanoco has announced it is working with several unnamed electronics companies, with the intention of bringing the first quantum dot televisions to market by the end of 2012.
There is one rumor that Sony is shooting for an early 2013 release date.
Unfortunately I don't have a link for this.
(March) Nanoco CEO stated Quantum LED TVs will be available 2013.
The chief executive of Nanoco Group today said he expects the first products containing its quantum dot technology to hit the market next year and he is confident the business will turn its first profit in two years' time.
And this quote from Sony.

"2013 will be the year that we will really fight back with new technologies. said Negishi"
Wiki: Quantum Dot has more natural colors.
First-hand Observer on CES: Sony showed real world demo materials. (It shows confidence on the natural colors.)
Color range: Nanocrystal displays should be able to yield a greater portion of the visible spectrum than current technologies. As shown in the diagram, QD Vision calculates as much as 30% more of the visible spectrum would be available using QDs in a QD-LED vs. a CRT TV.
Low power consumption: QD Vision estimates its nanocrystal displays could use 30 to 50% less electrical power than an LCD, in large part because nanocrystal displays don't need a backlight.
Color accuracy: Nanocrystal displays would yield more purity in colors than other types of display technologies. Some display technologies, such as LCDs, can’t create a pure red, green, or blue for the display; instead, they need to add a few other colors to those three to display pure colors. Quantum dots, on the other hand, create pure red, green, and blue to create all other colors.
Brightness: 50~100 times brighter than CRT and LCD displays ~40,000*cd/m2
Added flexibility: QDs are soluble in both aqueous and non-aqueous solvents, which provides for printable and flexible displays of all sizes, including large area TVs
Improved lifetime: QDs are inorganic, which can give the potential for improved lifetimes when compared to alternative OLED technologies. However, since many parts of QD-LED are made of organic materials, further development is required to improve the functional lifetime.
Other advantages include better saturated green, manufacture ability on polymers, thin display, same material used to generate difference colors, and higher resolution.

- Off-axis it was perfect. The LG OLED whites had a green tint off axis, and I didn't check well enough on the Samsung to be certain.
- Sony used much better, real world demo material. Samsung had a lot of CGI stuff that doesn't give you any indication how it might handle a skin tone, or a normal movie. LG had half of their sets running a horrid 3D demo loop (everything comes WAY out of the screen, giving me a headache instantly) and so it was harder to get a good feel for it. Seeing real material was very good.
- Motion was just so good. Nothing against the OLED displays, as they looked great, but just didn't have the same "wow" factor as the OLED.
- The Sharp 8K had incredible resolution, but otherwise the panel was just a bit ordinary in terms of off-axis, blacks, motion, and contrast ratio.
