Pre-Release Thoughts on Samsung LED DLP

[Hitman]

Hey Everyone!

Well, I'm upgrading this spring. Been waiting for the 2nd gen SXRD and along comes this 56" Samsung LED DLP with no color wheel. I've always liked the look of DLP and now with no rainbows, well, I'm excited... Since this is New New New and I can't find any info beyond the official press release, I thought I'd ask you all what you think. The Sony, well, it's an SXRD, it's Bigger. The Samsung, we haven't seen it except at CES but Cnet loved it enough to give it an award. Anyway, what do you think?

I THINK it is the first step of what all projection technologies will be. Simple as that. Instant on, instant off, no heat, no rainbows, a lamp that may outlive the projector... Just freakin' incredible!

How does it ACTUALLY work? Man, I can't wait to see it! But, it'll have to be front projection before I will really overly care about it. Rear projection is not likely to make an appearance in my home. SED may be the next thing working through my doorway.

where can I find out more about this LED DLP you speak of? Are there any links you can provide?

edit: nevermind, I fould a link. Too bad it's gonna be so expensive, cause I think that would be the perfect tv for me.

Hi, here's a few you may not have found:

The prices you're seeing are MSRP, street prices will be lower I'm sure. Well, I'm hoping anyway!

That looks interesting, and I am looking to get a 54-61" DLP rptv by the end of the summer. I will have to keep my eyes open for those

I don't see how switching to an LED light source is going to eliminate the rainbow effect. Maybe somebody can explain it, but to me this is how it looks.

Getting rid of the color wheel does not in itself eliminate the effect as it is caused by the rapid succession of RGB images before your eyes. In a single DLP system this is neccessary to create color, with or without a wheel. With a lamp, a color wheel is used to create the RGB images from white. It is my understanding that these new tvs will flicker their red blue and green LED's in quick succession on to the DLP chip, thus I'd assume the rainbow will still be present. The only way that I am aware of to get rid of rainbow in any projection system is to use a seperate device for each RBG - 3LCD, 3DLP, 3LOCS for example. Am I wrong? As to your question I'd go with the Sony SXRD hands down.

Quote from cnet article:
"DLP HDTV heavy-hitter Samsung announced four new big-screen rear-projection units earlier today and, in terms of potential image-quality improvement, the coolest is the HL-S5679W. This 56-inch single-chip 1080p-resolution DLP an entirely new light engine that ditches the tried-and-true color wheel/lamp system for a trio of LEDs (the "wobulated" DLP chip hasn't changed, however). The result is elimination of the rainbow effect that causes some viewers of DLP TVs to see brief trails of color in certain circumstances. The LED light source also has other benefits, according to Samsung, including the ability to let the TV display a wider color gamut; longer life before needing replacement (20,000 hours vs. 3,000 to 6,000 hours for a typical DLP bulb); and much shorter time to turn on--7 seconds--than typical bulb-based HDTVs....etc."

I don't see rainbows myself. But I do want to make sure my guests don't either. I've got to get a look at this TV and compare to the 2nd gen SXRD. Those cnet guys loved the Samsung enough to give it their Best of CES award for TV's. Worth checking out I think. All these fantastic HDTV's. Isn't it great?

I read that too. But forgive me if I say, in my very humble opinion, I don't think CNET knows what they are talking about. I read Samsung's site, and they didn't mention the elimination of rainbow effect. I'd think they'd be spouting that to the world if it were true. To me it defies logic. How could a single chip DLP produce a color image, without flashing RGB and the subsequent rainbows? This has been bothering me since I read the announcement from CES. Does anyone have a link or knowledge of how this works? Thanks.

I've read that the LED technology does not lend itself as well to LCOS but that it will be adapted sooner or later. It looks like the normal yearly advances in technology may offer some large jumps during the next 18 months or so with the advent of SED and possibly OLED.

Based on what I've read about this new DLP, it wont need a color wheel because there will be separate red, green & blue LED's firing at once to create a single image. Thus ending the rainbow effect. Is this everyone else's understanding?

Just wait for SED. Nuff said!!!

The Red, Green and Blue LED's fire in succession thus ending the need for the color wheel but not rainbow effect. If you fire all 3 at the same time, you end up with white light and you'd need something to manipulate it into color. ie-color wheel.

Good point, but I still wish we could get a definitive answer from Samsung or another manufacturer on how exactly that works because I'm still reading claims that this is doing away with the rainbow effect.

Are we the only one's debating this rainbow thing? Everything, and I mean "Everything" I'm reading is this is the end of Rainbows. I think it's the shear speed of the sequential firing of the RGB LED's vs. the old Color Wheel, that it will just not be possible to see it anymore. This is not your grandfathers DLP...Ha! Anyway, when this hit's the store's, I'm looking at this vs. the 2nd gen SXRD. Winner gets my dough! I'm kind of leaning toward the Samsung at this point, best of CES and because of the long term benefits of the LED's. Bulbs are expensive and I leave my tv on all the time. Anyway, don't we have great TV's to choose from these days?

I just read about this projector last night and had missed this thread. Man I am glad I havent taken the plung yet into a new Projector.

Clint... Any chance you guys are going to review this in the future?

September

I just spoke to a retailer who had this tv listed as available in May, and they said Samsung told them it's delayed to September.

Thanks for the heads up Tsunamaii - looks interesting, not sure which is the better choice between this and the Panasonic ae900u front projector.
