LED engine DLP... The ultimate technology?

[tranCendenZ]

I have to say, I'm very interested in LED DLP... It seems to be the ultimate technology...

No burn in.
No rainbow effect.
Good black level.
No bulb that burns out.
Relatively small.
Reasonably priced.
No user convergence adjustments needed.

About the only con is that its not a flat panel, but I'll give that up for much more reasonable price and better picture quality.

This Samsung is the first that uses the technology, it became available in the last month or two:

I will probably hop on this bandwagon to replace my 56" 1080i CRT RPTV once we are a few generations in. Looks good!

On paper it seems great. I've seen 2 in stores and the picture didn't wow me. it definitely didn't look like it can compete with the 2nd gen Sony XBR or even the A2000 series. Of course, with the TV setup and environment in stores that's a very weak judgment. I'm planning to get a new TV after the Christmas season is over, and I'd like to get an LED DLP if it looks good, but my vote right now is still for the Sonys.

Im waiting for SED to come out and decimate all

[Crazy Legs]

HD Beat (now Engadget HD, ugh) liked their Samsung review set. I've been looking forward to the technology to hit the market for a while now. I'm not planning to upgrade my set yet, but I'm hoping that if family and friends buy a new TV they will consier LED-DLP.

SED has several of the inherent weaknesses of CRT (and bonuses of course), though. Personally I think LED engine DLP has a chance of delivering a better picture than SED even - of course it won't be a flat panel like SED, though.

It will be interesting to see how this technology is refined 2nd and 3rd gen.

also watch for this coming late next year..


october 10, 2006 - If you thought Toshiba and Canon's SED technology was the only up and coming rival for the plasma/LCD/DLP establishment, think again. News.com.au reports today that a pair of technology companies, Australian Arasor International and American Novalux, has announced an entirely new technology high definition displays.



The technology is based upon a unique optoelectronic chip paired with a laser projection device to create the image. The technology is scheduled to launch in Q4 2007, branded and manufactured by companies like Mitsubishi and Samsung.

The technology partners that developed the technology are talking a big game. Speaking with News.com.au, Novalux chief executive Jean-Michel Pelaprat said "If you look at any screen today, the colour content is roughly about 30-35 percent of what the eye can see. But the very first time with a laster TV we'll be able to see 90 percent of what the eye can see." In technical terms, Mr. Pelaprat is claiming greater than 10-bit color depth for displays making use of the technology, unquestionably an impressive advance if it proves true.

A breakthrough in bit-depth is actually the least of the companies' claims. The News.com.au reports that the laser projection HDTVs will use a quarter of the electricity that current HDTV technologies do, and will also cost half the price, which technically would suggest about $1,000 or less for a 50-inch display in Q4 2007.

So far it seems LCD's and Plasma's will become outdated!

And upcoming are SED's, LED DLP's, Laser, and AMOLED

Think those will be years before they come down in price and become a standard.

[CR2500]

Not too off-topic, but if you had the choice of DLP, HD-ILA, or LCoS, which would you get for the money?

Like what? Only negatives I can think of about CRT is geometry and convergence aren't perfect but SED is fixed pixel so that shouldn't be a problem.

[Lupine]

Haven't had the pleasure of seeing an LED DLP, but the Consumer Reports preview was encouraging, especially considering the cost premium you pay for LED screens.

What about the eye destroying part? And the hugeass size of the TV's... my 3 year old Philips CRT 36" with stand weighs more then i do .

Or we talking about the actual technology... though the refresh rate still counts on that one.

[vazel]

Hmm, I never thought about SED inheriting the 60Hz flicker problem. Although it's never bugged me for movies and games. It's only when reading a lot that it gets annoying.

I'm not sure it even does inherit that problem, that's one of the reasons i don't use CRT's though. My eye's are strained enough as it is .

SEDs are only slightly larger (in depth) than LCDs and Plasmas.

They are the size of flat-panels, but have the PQ of a CRT.

And yes, CRT still reigns King in the PQ department.

That is debatable. While I currently use an HD CRT because I feel it is best overall PQ right now with least disadvantages, near the edges of the screen and corners CRT HDTVs are pretty much standard definition while the center of the screen is high definition - poor focus at the edges/corners is an inherent weakness of CRT. Not to mention the vast majority of CRT HDTV sets cannot fully resolve 1920x1080 resolution (you need massive 9" CRTs for this) anyway.

SED will also inherit the burnin weakness of CRT. We have yet to see how many other CRT-weaknesses or new weaknesses the technology will have. Not to mention it will be prohibitively expensive.

I hear Laser DLP will also be quite expensive as well... Seems like LED DLP might be the best choice in its 2nd & 3rd gen at an affordable price. It seems the first gen LED DLP from Samsung axed dynamic aperture to cut costs - adding that back in for next-gen of LED DLP could very likely bring it to the top of the pack overall with the enhanced contrast level that can offer combined with the other benefits LED DLP has shown thus far.

Cheaping out on CRT tech leads to poor focus and ability to resolve resolutions. They are quite solvable problems. However the burn-in issue is of slightly more concern, mind you it has again been less of a concern for years now on non-rear projection CRT tech for quite awhile(thanks to improvements in CRT tech)

RE: CRT

You're right, out of the box, a CRT will have the problems you noted. But, after the break-in period, and a ISF calibration, it's picture cannot be rivaled.

Mine is three years old, it's on about 6 hours a day, and it doesn't have the slightess hint of burn-in.

RE: SED

All the tech articles I've read said they don't suffer from burn-in. If you've heard otherwise, please share, because I'm interested.

Thanks!

[tranCendenZ]

Well it looks like LED DLP might be it in the near future. SED just pulled out of CES 2007 apparently.

I don't see how SED won't have burn-in since it uses phosphors, and most tech articles I've read seem to agree there. Also, even after ISF calibration CRT generally suffers from poor focus in the corners compared to the center of the screen; usually if you sharpen up the corners the center goes out of focus and if you sharpen up the center the corners go out of focus.

[CR2500]

and SED also has eyestrain + radiation

I think Flatpanel TFT LCD TV's are the way to go..

Not if you want the best in color and contrast. LCD has gotten very good with color but that's with the high end models. Most everyone seems to be getting the mediocre ones, like the popular Westinghouse sets.

Also, some have screen-doors and there is no such thing as black on an LCD.

I don't think thats ture.. I have a 40" Samsung LCD and I find the black to be more black then that on most CRT TV's and the contrast is 6000:1 dynamic contrast ratio. LN-S4096D is the model and here is the link..LN-S4096D but it has amazing color and depth..

True, if you have the $$$ for a good Aquos/Samsung, they are true Home Theater quality. But for the most part I was refering to the Tier-2 brand LCD HD-monitors.

[vazel]

pff, whatever. it's impossible to have better blacks than a crt on a device that gets its light from a backlight.

Yea the back light kinda messes the whole thing up.

I will try to find the article on it but, theres a company that makes 50 inch LED powered LCD tvs, at a whopping 50K. It sports a 200,000:1 contrast ratio which he better described as infinity. The black on the tv is just like if it was off. The reviewer said though that the unit made insane amounts of heat and images with light like sunlight were literally blinding.

Wasn't that the HDR TV? It required liquid cooling i think, all i know was it was huge, ugly, and hot as hell.

So pretty much a CRT
