Laser TV — the Death of Plasma? 351
spoco2 writes, "As reported in major news outlets yesterday in Australia (The Age, the Herald Sun), a new television technology has been developed which is touted (by the developers) as far and away superior to both plasma and LCD. From The Age: 'With a worldwide launch date scheduled for Christmas 2007, under recognisable brands like Mitsubishi and Samsung, Novalux chief executive Jean-Michel Pelaprat is so bold as to predict the death of plasma. "If you look at any screen today, the color content is roughly about 30-35 per cent of what the eye can see," he said. "But for the very first time with a laser TV we'll be able to see 90 per cent of what the eye can see. All of a sudden what you see is a lifelike image on display."' The developing company, Arasor International, is said to be listing on the Australian stock exchange shortly."

Yes, some entrepeneurs will push the envelope when trying to introduce something new. I used to work at Mitel Corp, which made business telephone systems. After much pre-announcement, we were supposed to roll out our SX-200 at a major trade show. Unfortunately, the software wasn't fully debugged, and so the thing didn't work properly. So Terry Matthews (that's Sir Terry now, of course) went out, bought a NorTel SL-1, and installed it at the back of the booth behind a curtain. They ran cables out to the SX-200, which was to all intents and purposes an empty shell. Everyone thought the SX-200 was fantastic, we got a lot of pre-orders, and when the software was debugged just a few months later, the SX-200 became one of the most successful PBX's of all time.
So there's certainly precedent for the idea of presenting something as a "done deal" while it's still in development. The question is, will the Laser TV actually appear in the market, as the SX-200 did?
And will we need goggles to watch it? The goggles.. they do nothing!

Colour gamut (Score:5, Interesting)
The problem with the extended colour gamut of the new system is that existing source material is based on the sRGB colour space, which encompasses roughly 35% of the eye's gamut. Anything shorter wavelength than blue, such as spectral violet; many saturated greens and oranges, and most cyans are not available, and the nearest colour is used.
We're all used to this, so when a violet flower is shown as purple (red + blue) on our displays, we don't question it. But try putting a vase of violets next to your TV and you'll see the difference.
Some proper digital photography setups try to improve on the situation using colour profiles, which is simply a lookup table to transform the RGB colours in the file to absolute colour values.
Digital cameras can record colours outside sRGB, so if you ensure your workflow never enforces that constraint, you can end up with a file that can be printed using colours your monitor can't see.
Typically, the input file (usually a raw camera file) is transformed via a device profile (representing the camera's actual spectral response) into a working space (a device-independent space for editing). Whilst editing, the image is viewed using a transform to sRGB (or your display's output profile, if you've calibrated it), but this restriction is for viewing only and doesn't change the file. Then, when you print, the image is converted via a device profile for your printer to print to the extremes of its capabilities - which may exceed sRGB in some colours (e.g. cyan), and be even worse in others (e.g. pure blue).
To make use of this new TV system, we'd need something similar - wide-gamut source material, and device profiles for each set (or simply assume sRGB as default, for backwards-compatibility). Otherwise, it's like listening to music mixed for cheap portable radios (i.e. most current CDs) on a real hi-fi system.

Most 6 or 7 component inkjets can go well beyond sRGB gamut.
Life stops being simple and nice once you take that step, thought. With AdobeRGB for example, you cannot share any of your images with your friends or print them in commercial shops unless the recipient can handle color profiles properly. XP image preview actually can, but none of the browsers do.
True, you can change the profile but unless you've got full photoshop, it's more conversion steps as the freeware utilities that I'm aware of can only do TIFF and JPG.
2nd hurdle is actually getting the photos to print. You have to be able to bypass all windows color management (which uses sRGB) and use photoshop (or photoshop elements) to print, which needs to have the profile for your printer AND photo paper for things to work right.
As an end result, you *may* get images of a lagoon or something that has deeper hues your commercial print shop would print. But how many of images like that "ordinary" people have in the 1st place?
There are even wider gamuts as AdobeRGB still doesn't surpass what you can see. I think PhotoPro will show all the colors (reference) eye can see and in fact quite a lot it can't, since color vision is not nice and linear.
Bottom line is, unless you're absolutely sure what you're doing, stick with the sRGB! Going with AdobeRGB or similar will make your photos look WORSE unless the rest of the cain supports it.

n the first place, I seriously doubt that there's any meaningful way of measuring the "percentage coverage" of a gamut of colors, since the mapping of colors into a plane is somewhat arbitrary and there are two very different systems in wide use. I notice that this comparison of Adobe RGB vs. sRGB [cambridgeincolour.com] doesn't try to estimate any "percentages."
Neither does Poynton's invaluable Color FAQ. [poynton.com]
Second, if we're talking about something like "area included in the CIE xy plane by thus and such system of reproduction" as a percentage of "area included by the entire spectrum," I seriously doubt that you can get a number anything like 90% with only three primaries. You're still trying to approximate a blobby blunt shape with an inscribed triangle.
The article is so vague on details that it's not clear how many primary colors are used. If it uses six primaries instead of three, I'm prepared to believe it could give meaningfully better color than traditional systems. How important that is remains to be seen. HDTV gives obviously, dramatically better picture quality (in terms of resolution) than traditional TV, but it doesn't seem to be setting the world on fire.
The big question, of course, is where one would find program material encoded with more than three primaries; it would need to be specially recorded for this system (requiring new video, broadcast, and optical disk standards).

Red lasers need not be frequency doubled because they can manufacture Diode lasers to that frequency and is available in higher power ranges. Blue DPSS lasers were developed, usign 808nm infared lasers frequency doubled, the power available is still really low, (and I can't wait to rip apart a blue ray drive to get the laser out!) and the lasers are extremely expensive. Hopefully with greater production of blue lasers the prices will go down.
The next issue to deal with in the U.S. (I don't know austrailian law) lasers are regulated by the FDA and any laser over the power of 5mw that exposes radiation to the public has to have an FDA varience to legally operate.
