I've been reading about these for at least a year, but it is FINALLY commercially available. I'll take a dozen plz, k thx.
Samsung LED TV


I dunno, maybe it has been available for a while, but I only recently saw the commercials for it, and got excited. This is technology that can revolutionize more than just TV's. It is one step closer to thin-film LEDs, and that could be used to heads-up displays in automobiles, aircraft, glasses (eventually contact lenses), etc.

Just wait...

Well, LED is great and all, but...

OLED is really where it's at. Talk of painting a TV (doubt it will ever happen, but the fact that the tech could definitely get a wall to change colors is awesome) sold me.

If this is the 1st gen, super crap tech.. then I can't wait till they can scale it up.

I'm kind of saddened that laser TVs haven't come farther. They may not be the best for a ton of applications, but they kick some major butt as far as TVs go.

peace

I think a number of TVs would get thinner (though admittedly not that thin) if all the components except the screen and backlight were moved to a box beneath the TV.

That's the thing. The hardware to control the tv won't get much bigger. And if you spread it out, you'll have a 1" thick TV. With better colors and blacks that are truly black, not the my TV is more sorta black than your sorta black. And the power consumption continues to drop w/ OLED. It's better in pretty much every way. They have a little bit farther to go w/ getting the life of the different colors up to par, but once the tech matures, it will be everywhere. It's already mature for phone screens, and has already started coming out (AMOLED).

Oh I totally agree, its just that for the time being, large screen sizes aren't feasible, and longevity is poor. I don't want an 11" TV that needs to be replaced in a year.

Maybe it's just me, but I'd rather the TVs remain a bit thicker and the components stay where they are. You're either going to have a TV wall mounted or on a stand. My LCD TV for example is on a stand, and since it's not completely up against a wall, there's just about half a foot of empty space behind it so I've got plenty of room and added thickness doesn't get in the way of anything. Likewise, if it's wall mounted, if it sticks out from the wall another inch, is it really going to intrude into your space that much? I know there may be a few specialized applications where a TV that thin might be necessary, but for me, I'd rather have a thicker TV and have more room for my other components.

Thinner = lighter = easier.

imho and all that.

That is true. I never move my TV so weight didn't cross my mind.

The biggest advantage of LED TVs is that the backlight has become obsolete. LEDs produce their own light, creating a more vivid picture. It is not filtering unwanted color from a super-source (backlight), but is instead producing the wavelengths required to accurately display the picture. Since there is no backlight to filter out, the black can be an actual black (absense of light) rather than an attempt to block out a super-source. No backlight also means MUCH less power consumption, especially compared to the incredibly small amount of power required to turn on LEDs. Without all that heavy backlight hardware, the TV can become much lighter as well.

I am pretty sure that ghosting won't be an issue for this type of TV too, but I am not sure about that one.

Are you sure there is no backlight? I thought these TVs use the same panel technology (Samsung=PVA, LG and Panasonic=IPS), but the backlight source is now made up of LEDs, instead of traditional light sources.

Think MirageX is right.

These cutting-edge TVs use LEDs as their primary light source, rather than traditional Cold Cathode Fluorescent Lamps (CCFL).

I know in HUGE HDTV's (think new one in Kaufman Stadium) can use LED's as their pixels, but that's only b/c the massive viewing distance blurs them together to look like 1 pixel.

<sidenote + rant>
I was in cpe210 yesterday and some 213 students kept calling LED's: leds (like the metal, lead). It was annoying to no end.

Yeah ShadowCat is slightly confused. The panel technology is the same (the part that decides what COLOR the light that gets through is), the backlight is different. The new LED backlights allow groups of pixels to be selectively darkened depending on the light levels necessary. This allows the better CONTRAST ratios, and "true" black levels. Older CCFL type backlights were always on, and relied on the panel to block out its light to create black levels.

So in a LED TV the backlight is NOT obsolete, just upgraded. Its like going from one light bulb to light a room to two dozen decent flashlights that can be adjusted and turned on/off independent of one-another.

Since SC made the thread, I assumed his seniority would assure a properly placed thread. That coupled w/ I only use the "view new posts" button anymore, means I'm not gonna catch it.
