Samsung's new 81 series promises to offer dramatic improvements over existing LCD technology. Please post your impressions (if you've managed to see one of these sets in person) and news here. Thanks.

The 81 series ups the ante with an LED backlight, bumping the contrast ratio to a measly 100,000:1, and also comes with 10-bit processing, 8ms response time, an ATSC / clear QAM tuner, CEC HDMI, USB, and also lands in August in 40, 46, 52, and 57-inch sizes( for $3000, $4000, $5000, and $7000, respectively).

The 81s look really interesting.


Will be accepting Sharp's refund offer for my 52D62U and was planning to plow it into a 52D92U in Feb but now I wonder if I should wait for the Samsung 81.


5 months seems like an eternity in LCD land.


On Aug 15, 2006, the D62Us weren't even out (and banding was not the most common word). I thought I got a great deal at $3400 in mid Oct; now 3 months later, they can be had mid $2Ks....

I saw this set in person. Was absolutely impressed. What pissed me off is the Sony people didnt know if the new XBRs were local dimmed or not. So as of now, its the 81 for me.

Everyone who's seen it seems to have a similar opinion. Finally, a display we can be excited about.

From TWICE (This Week in Consumer Electronics) magazine

Quote:
The high-end 81D LCD TV series, which ships in July at prices to be announced later, employs LED backlighting in four screen sizes. Models will include the 57W-inch LN-T5781D, the 52W-inch LN-T5281D, the 46W-inch LN-T4681D, and the 40W-inch LN-T4081D. Each is said to produce contrast levels of 50,000:1 and produce 105 percent wide color gamut. All will also offer 1920-by-1080p screen resolution, new Super Clear Super Patterned Vertical Alignment (SPVA) panels, WiseLink with Bluetooth wireless connection technology and three HDMI inputs.


The OCAP interactive cable-card system, previously reported as a new feature in the series, has been withdrawn, a company spokesman said.

I wonder if LEDBL with Dimming is potentially not creating new types of artefacts. I would like to test those sets with "end of a movie" type material, scrolling white letters on black background. Most of the display would be then dimmed completely but letters would need to be fully lit. In effect it might be that there will be visible non-perfect blacks around letters.


Another observation is that Sony and Samsung use the same panels. But only Sony is showing 70" display with dimmed LEDBL and an 82" prototype. Samsung is targeting such displays only for professional market. It looks like they split the market to avoid competition on higher shelves. This allows Sony to charge 33 k$ for the 70 incher.

One comparison showed how the LED backlit set, even working at 60 hz, was able to show motion as clear as a conventional set running at 120 hz.

Im confused, are these sets 120hz or not? No article seems to mention if they are while the last one quoted says its 60hz and yet you claim them to be 120. So which is it?

Samsung is aping Toshiba's 120Hz response time tech to reduce blurring on LCD (or did Toshiba copy Samsung? Too close to call). Samsung is also adding LED Backlight Scanning.

well if it truly is 120hz and has all those other features, then im in heaven. I cant wait to get this dream tv of mine. I will pay whatever the cost.


BTW, how come some sites say 50000:1 contrast ratio and other sites say 100000:1? I want to get either the 40 or 46" screen and would like to know which is the contrast ratio.

The one on display at CES was 60hz, the 81 series that will be released, will be 120hz. I am very worried about lighting artifacts, depending on the resolution of the LED array. The example of white text on a black background is a good one. The effect could be a white halo glowing around each word.

Well at least in the picture at the top of this thread the black areas next to the very bright/white area don't seem to exhibit any halos. I sounds like you observed this set in person at CES, did you think you saw any of these effects? I hope not, I have high hopes that this might finally be the HD LCD Set I will settle on.

Okay, so that explains the 60Hz/120Hz confusion. Thanks.

There's little doubt in my mind that Samsung licensed "local dimming" technology from Brightside which owns all the patents for backlight modulation. If I'm right, then this article should serve as a nice explanation of how this technology works and what we might expect. I don't think Samsung will be using 1400 LEDs in their backlights, but still, even a fraction of that number should produce stunning results. We'll have to wait and see. So far, things are looking good.

Having recently purchased a 720p DLP front projector, I wasn't even planning to buy a flatscreen TV, but this is making me reconsider. I don't own a TV today so the justification for one will be that much easier.

how bad is overscan that everyone talks about on the samsung sets? I set the sony tv at the store to be full pixel and then viewed it placed right next to the samsung 1080p tv. I could see a tiny bit of overscan on the samsung, losing like a half inch of the picture, but It really didnt bother me that much. I dont know whay people complain about it? I would rather lose that really tiny ammount of tv then deal with banding and cloud issues on other sets. Samsung all the way. Although of course I do hope they allow 1:1 pixel mapping.
