The Samsung Intergalactic Empire keeps presenting hot models left and right. And some LCD televisions too, like this 1080p 70-inch model they introduced today in Korea, the first commercial Full HD TV ever with selective local LED backlighting. The new system, which will be sold around the world during the second half of the year, allows for some amazing features.

To start with, the local backlighting means that the TV can automagically turn off the LEDs in dark areas of the image. This not only brings deep blacks and a 500,000:1 dynamic contrast ratio but also, according to Samsung, it reduces the power consumption "by as much as 50%." It also implements LED scanning, in which "LEDs are rapidly shut off in sequence" eliminating flicker and ghosting.

Samsung has quite a bit of these technologies lined up. While this one will completely turn off the LEDs in some areas, future versions of the technology will adjust the backlighting dynamically over finer surfaces.

DISCUSSION

You have to use the eye test, because the specs are guidance, but you've got to live with watching the thing every day.

For example, at BB I found out that they use CRAPPY input material for their HD displays. They use DirecTV demos at 720p and then split it off to about a gizillion sets. So that really doesn't tell you much.

My first HDTV, from HP (32" LCD 720p) had good specs for its time and equally good reviews. And while it turned out to be great for games it totally bit the big one on SDTV.

My second, a Samsung (50" Plasma 720p) does a really awesome job at SDTV and the HD looks great too, but by far the best SDTV handling I'd seen.

My most recent (and last if my wife has anything to say about it) is a Sony (40" LCD 1080p) which was bought mostly for gaming and looks really great. It does OK with the SDTV, but because it is not my main TV for watching, I don't mind.

Specs help, but...
