Those are two types of lighting used for the back lighting they use in LCD computer monitor's & LCD TV's to light up the screen from screen of the LCD from the back of the LCD. Do you understand what I am saying???

But there are four (4) types of LED backlighting. See - »reviews.cnet.com/2795-6482_7-399.html
Mine is edge-lit without local dimming, but the backlighting will globally dim on dark scenes to improve the black level. Mine also has backlight scanning, which I have disabled.

I agree that they should be marketed as "LED illuminated LCD TVs".

Now I have to get the WiFi streaming set up properly. Samsung's AllShare server was crappy. The TV works with the Win7 / Windows Media Player streaming, but the setup is clunky and I have to rename MKV files to WMV for them to play. Also, there's no real FF/rewind function.

Any suggestions on a better DLNA server than what's built in to Win7?

While they're definitely better w.r.t. size, power usage, and longevity, I don't think edge-lit LED have any inherent advantage w.r.t. picture quality.

I'd just go to some more stores, widen the scope, and take the time to look at more TVs before buying one.

The real question is it a one-off defect, or will I have similar artifacts if I buy one of these $800 TVs.

Regarding the Sony, 46" is too big for the room. Do they have any 40" versions?

There were noticeable bright spots near the corners. See above. The bright spots in the lower right are about the size of dimes. (The spots near the laptop image are just reflections of the store lighting.)

Other than that, the picture looked fine. Don’t know if I’d want spots like that after spending $800.

Most HDTVs has glossy screens. It seems like this would be a problem with the bright reflections. Does anyone know of any 37" or 40" TVs with a matte screen and that will play movies/videos via a USB port or WiFi?

IllIlIlllIll posted : the only very minor issue i have with led edge lit lcd panels is the uniformity of the light across large lcd panels.
its obviously brighter on the edge of the display panel than the center, most regular people wont even notice it.
the other very minor issue is the white tone with a slight blue hue to it but again, most people wont notice this.
even CFL back lit lcd displays have a very slightly "warm" white due to the phosphor used for the CFL tube.
overall, i prefer led edge lit for many reasons, less power consumption & heat, thinner display panel and longer life of the led's, the led's would most likely outlive (depending on how hard they are driven) the lcd panel (chances of a single pixel defect is much greater).
i dont drive the led's more than level 1, its better on the eyes when youre 3 feet from the set in a dark room and its better for the led's.

said by Jahntassa:

LED-LCD are generally brighter, or at least better color reproduction, generally better viewing angle, thinner, cooler, and use less energy. Plus, in theory, they should have a longer lifetime than CCFL-LCD.

First, I should note there are two types of "LED TV" -- edge lit and full back lit. Almost all LED TVs are edge lit, and they use white LEDs. For those, "thinner, cooler, and use less energy" definitely applies. However, there are 'full backlit' panels, and they use a lot more energy. Of course there's only a handful of such TVs and monitors were ever produced -- one is a now discontinued Sony Bravia. I think they used RGB LEDs instead of white ones -- they definitely had better color reproduction and are much more stable.

As for the usual edge lit TVs -- viewing angle is really the property of the LCD, so the backlight should have no effect on it. Brightness doesn't depend on technology, and color reproduction I think really depends the individual components used. They are definitely different, but whether one is better or not, that's debateable. Personally, I think wide spectrum CCFLs are better than most white LEDs. RGB LED can be better than even wide spectrum CCFLs, but you won't find that in many panels, so for practical purposes, its a moot point.

Another thinig is that even though LEDs can have a very long life time compared to CCFLs most white LEDs suffer from color shift because in reality they are blue LEDs with phosphor. (there are whites made out of RGB LEDs, but I don't think those are used in TVs)

But to answer your question directly, "What is an LED TV?".

This is simply a LCD TV that is lit by LED's from behind rather than being lit from the edges with various flouresecent bulbs.

There is a link on the page you rpovided that has a brief explanation of the differences in flat panel TV's that offers some explanation of the LED.
