Sony has demoed a new type of display they are coining 'Crystal LED'. It literally uses 6+ million LED's (1080p in a traditional RGB sub-pixel format) as the screen. Besides the obvious benefits of LED, this is essentially using the LED casing as the screen, further improving efficiency and contrast versus the traditional method of attaching the display substrate to other layers behind a screen.
Like OLED, this is self-illuminating and should prove to have deep blacks and very low response times.

It's the viewing angles, really. Sony's 55-inch Crystal LED display prototype is an impressive piece, but being able to view clearly from near-90 degree angles, color intact, is quite a spectacle in person. We did our best to recapture it that from the showfloor of Sony's CES 2012 booth, which you can view in the gallery below. We spent some time watching a series of slides and video clips on the device, both in bright light and in a more cavernous unit next to an LCD TV. The colors were more vibrant, particularly the reds, and blacks were truer and darker. The colors, it should be noted, also looked a little bit warmer than its 55-inch BRAVIA LCD counterpart. As far as the actual hardware, there's not much to the eye — square no-nonsense plastic edges. Remember: it's a prototype, after all. It may be the future as Howard Stringer sees it, but it's more evolutionary than revolutionary.

While LG and Samsung trumpet their OLED prototypes, Sony has apparently moved on from the tech, choosing to highlight a new 55-inch Crystal LED prototype at CES 2012. Its display relies on "ultrafine" mounted to each RGB color, equivalent to the number of pixels, which is all affixed directly to the front of the display. We don't have the full details, but so far Sony is claiming 3.5 times contrast, 1.4 times the color gamut and 10 times faster response time than LCDs.
Update: We've seen it in person and we can certainly say it was both bright and beautiful, however it was only displaying still images at a frustratingly slow refresh rate. In other words, it was a prototype, but one we'd love to watch some real videos on some time soon.

[CES 2012] Sony has shows its Crystal LED display prototype to the world for the first time. The 55-inch display has a native 1080p resolution, but what makes it so extraordinary is that it uses a combined 6 million of tiny individual LED lights. Why 6 million? A 1080p display has about 2M pixels (2,073,600 to be exact), and each pixel is composed of three sub-pixels (Red, Green and Blue). To build this Crystal LED display, Sony had to manufacture, place and wire those 6M LED lights – that in itself is impressive.The advantage of such a technique is extremely high contrast because there is no notion of backlight here. Crystal LED is a self-emitting display technology, so a black pixel won’t be grey because there is light bleeding out from the backlight. The pixels can also be mounted closer to the display glass, which makes the view angle much better. Finally, because the light doesn’t go through color filters, the color reproduction should be much better than what an LCD would provide for example.
Beyond this amazing feat of technology, the real question is: is it better than OLED? It may be in some aspects. For example, OLED displays are notoriously hard to tweak when it comes to color. Even at manufacturing time, every single display needs to be tested and tuned to provide colors similar to similar displays. That said, the idea of having 6M LED lights seems scary from a manufacturing and economical standpoint – that’s why Sony isn’t committed to making this a product yet. However, Sony did have to show some kind of answer to LG and Samsung 55” OLED TVs, and LG has already committed to make this a “product” that buyers can get “in 2012”.

The may not even be a prototype, but more of a concept tech (ie. unclear whether it will be pursued), but it certainly is interesting. I had always assumed the reason for OLED was both form-factor AND efficiency. If the latter isn't the case, or Sony has solved the problems, this could prove to be a viable competitor. Since there's no backlight, we're really talking about what? A few cm's thickness or so? This isn't a phone, so no one is really going to care about that versus a 5mm display.
Regardless, this is a very interesting demo. Could this be the start of a new LCD/Plasma war? Only this time it will be OLED/LED? If they actually pursue this, I'm curious what sort of manufacturing process is involved? The promise of OLED is will eventually have very cheap fabrication processes. Is this something that can follow suit?
Holy HELL ... check out the viewing angles
