LED TV ?

[Bob Pl]

One of my kids is looking at TV's 42 - 46 inch & she asked me about LED TV. I do not know much. I have a 5 yr old LCD that's just fine.

Any links or tech opinions on LED?

Thanks

It's a rebranded LCD for marketing purposes.

Don't know about the "marketing purpose" as George alluded but he is right in that it's a different type of LCD. Instead of liquid crystals, it's light emitting diodes. Now I was just at a Magnolia A/V and LEDs have a brighter pictures that "pops" out at you visually and will last longer, Plasmas are more of a natural look with deeper blacks. LCDs are cheaper and LEDs are the new "fad" (i.e. 3D tv)

OK, that's two strikes...

An "LED" TV is an LCD that features an LED-based backlight rather than a fluorescent one. Current marketing trends seem to just collapse LCD-LED into "LED".

An LED backlight can help save power as well as allowing the backlight to be dimmed for dark scenes for darker black areas. Some implementations allow for select areas of the screen to be dimmed.

So, to answer our question directly.... "yes" on "LED" TVs.

Some implementations allow for select areas of the screen to be dimmed.

This will be more expensive than the implementations that use LEDs lit from the edge of the screen. I've seen Samsung C6300 series of these cheaper edge-lit versions at Best Buy and thought they looked great compared to the older fluorescent-based Samsung A650 series that I have in my apartment now.

I find CNET HDTV articles to be very good. This one (though with older HDTV models) talks about the differences that Will summarized:

We just bought a new LED they look much better than any of the LCD tvs that I saw LED backlit with local dimming is the hot ticked, for value Costco has the Samsung 6400 that is edge lit but a good deal

Aren't the edge LED lit ones the super, super thin models. There's some wow factor in a 50" TV that's less than 1" deep, even if it's not quite as good as a back lit.

Just random thoughts, I've had to replaced plenty of burnt out florecent bulbs in my house, I've never had to replace a burnt out LED (any I have plenty of them running in my e-projects).
