Samsung LN70F91BD 70" LCD TV (Source: Samsung)
Samsung delivers world's largest commercially available LCD TV

Samsung aims to impress with the retail launch of its new 70" LCD TV in Korea. The new Samsung  LN70F91BD forgoes the traditional CCFL backlight in favor of an LED backlight for improved picture clarity.

"I am pleased to introduce the 70" Full-HD LCD TV with innovative Local Dimming Technology," said Samsung Digital Media President JongWoo Park. "Samsung will continue to strengthen its LCD TV leadership, enhancing Full-HD and large screen LCD TV line-up.

Also new to the TV is what Samsung calls "local dimming backlighting." Since the backlight consists of hundreds of LED elements, an image displayed on the screen can range from maximum brightness (LEDs at full power) to complete darkness to produce true black (LEDs turned completely off). This differs from traditional CCFL LCDs where black levels can appear more grayish.

Samsung says that the use of the LED backlight gives the LCD TV a dynamic contrast ratio of 500,000:1 while power consumption is cut by as much as 50 percent. According to AVING, the LN70F91BD features ACAP, three HDMI 1.3 port and a USB 2.0 port.

Samsung's 1080p 70" LCD TV is on sale now in Korea for 59 million won ($63,425 USD) and will be available worldwide during the second half of 2007.

Hmm....
5000:1 contrast ratio...or 500,000:1 contrast ratio.
I'll go with the Samsung.

We'll just see about that 500,000:1 contrast ratio. The manipulations manufacturers use to get those numbers border on fraud. Nonetheless, I am looking forward to this technology for its improved efficiency, and promised picture improvements, especially since I am a year or two away from buying a new television.

Yeah, no kidding. Take contrast ratios with a grain. There are some spectacular lower contrast displays that outperform many higher contrast displays. Sacrificing picture quality or using questionable measures just to put a higher number on the box means nothing.

Go to a shop where every display is properly configured and compare side by side. It takes more work and patience than just ordering from hdtv4less.com, but you won't be disappointed.

The light source can be completely turned off. Comprehend before you speak.

It should the same principle as with the Brightside TV.

this is the same contrast that can be seen on a plasma which also turns on or off to the actual black level of the picture.

current lcd's suck. black=black not some odd dark color. plasma's still are the best picture, and, being that you are looking at a picture, that is the only thing that matters.

LED lcd's are long overdue and will take a long time to be inexpensive. I am hoping for a nice 24" lcd (mva maybe?) that has LED backlighting. OF course, this samsung has full control from off to full brightness on each LED. I am not sure the same tech will be put into a 1000 dollar 24" monitor technology. ALso, where are the specs on the color Bit.... i always see contrast ratio and resolution, but your eyes are most sensitive to accuracy of color, something that is left out of the advertisements and "spec" lists.

Plasma TVs may have beautiful colors, but their resolution sucks horribly, plus all plasmas I have seen have awfully large dot pitch. You can actually tell the pixels apart even when standing a couple meters away from the screen. They are only comfortable to look from a distance.

Was 2002 the last time you looked at a plasma? It must have been a really large (50"+) EDTV plasma if you can tell pixels apart from "a couple meters" away. Plasmas are capable of the same resolution as everything else: 1920x1080.

i agree, i worked at an electronics store and i have to say that i don't have much good to say about plasmas, they are horribly inefficient, i haven't seen one with reasonable color reproduction (its usually always an artificial neonish color), even though it goes to an off state there is almost always a green tint to the surface, so its NEVER really a shade of black, which just more even throws off the colors, the glassed screens have such a ridiculous amount of glare, if the TV is on the wrong wall you wont be able to see the picture anyway. and the dot pitch is still huge compared to LCD, its a ton better then the XDTV resolutions, but its still not impressive. now i'm not saying that LCD doesn't have its downfalls, but i put plasma at the bottom of my list. honestly a Sony or Samsung DLP will beat either LCD or plasma for an amazing picture quality.

Impossible. Plasma black is true black unlike LCD see-through back light. Have you tried watching football on an LCD? Motion blur galore. Thanks, but no thanks.

That must've been a pretty sh!tty TV, cause ghosting only occurs on really slow LCDs. Most newer LCD's have single-digit response times, and I'd doubt you'd see blurring on those.

well what ever sony did with our new bravia X series 946 inch 1080p LCD) it works. motion blur = non existant, blacks = okay theyre not perfect, but theyre pretty damn close, easily a match for the 36inch WEGA crt it has just replaced.

also the 40inch sammy we picked up (1080p LCD) has amazing blacks, vivid colours and good contrast, but i think thats due in part to a glossy coating.

plus samsung really over do it... i mean i had my retina's burning when watching a football match, the whole pitch was just a intense lime green, forza 2 looked like complete ass on it too.

and that wierd movie+ setting, which i read can add up to 10 additional frames into what your watching doesnt have produces some wierd effects. sometimes its like watching something in fast forward. the combo of that and how it overblows things made tom cruise in war of the worlds actually look like he was stood on a stage with some bright lights on his face while they played this random film in the background.

wierd

plasma's can be adjusted for color correction if "your store" is high end enough to offer adjustment services.

With that amount of money I can almost add a room to the house and put a 200" HD projection system in.

He was referring to the Panasonic 103" TV.

On topic: I am curious to see how the LED picture differs from traditional back-lighting aside from having incredible contrast ratio.

wow nice language. How about a little clearer question, it could have easily meant have you seen this one (the article) or this one (the topic).

How about you ask a clear question instead of getting all ticked off about someone interpreting your vauge question incorrectly.
