I would like to know the pros and cons of LED vs LCD for:
Desk Monitors
Home TV use
LED monitors and TVs have both dropped in price and I am thinking of upgrading to a 24" monitor for my office and possibly also upgrading the home TV size.
Appreciate the feed-back.
Thanks

LED TVs are technically a member of the LCD TV family. The display screen on a LED is a liquid crystal display the same as it is on any other LCD TV. The main difference between the two lies with different backlighting techniques which may change the picture quality characteristics dramatically.
Traditional LCDs have used some form of flourescent lighting from tubes to much more advanced flat arrays of lights. LED TVs use Light Emitting Diodes to light the LCD panel. Just as there are different styles of flourescent lights in traditional LCDs there are also different styles of LED backlighting. There are LED TVs like the Sony KDL-55XBR8 (see review) that have a panel of LED lights behind the LCD panel. In the Sony the LEDs are tri-colored and can be controlled in banks for an effect called “local dimming”. This allows darker areas of the picture to have the backlighting dimmed behind them resulting in better contrast and black levels. In the Luxia line of Samsung LED TVs, the LED lights are surrounding the edge of the panel and this arrangement allows for the very slim depth of those models. Without the ability to do local dimming these are functionally similar to traditional LCDs so in this article we will be comparing local dimming LED TV to traditional LCD TV.
My understanding is that LCD’s now use LED as a lighting source. As such, it’s not LCD VS LED. Old LCD tech has a different lighting source that won’t last as long as the new LCD’s that use LED lighting. Also uses less power. I also believe the LED lighting tech allows for thinner devices.
Ping, to you!
The best monitor in my book, is the HP w2338h. The brigthest 1080p LCD resolution that I’ve seen. I was given one at work when they upgraded me from an old CRT... Loved it so much, I went to the store and still compared it to others and brought one home.
For home get yourself a samsung led 240hz I have last years LCD from them and it was top of
the line at the time the new ones are probably even better. They should be cheaper because 3d tvs are coming this spring if you Want to wait for those
Any of the major LED tv producers; Vizio, Samsung, Sony, LG, Toshiba are “good”. No tv is perfect but you should pick a price range, pick a size, and pick extras like PIP, Game mode, inputs, sound bar capabilities, and see what models if any fall into that range, and then visually compare them yourself.
I have been looking at the 55” Vizio 552, various Samsungs that are backlit, and the LG LH55. Not sure which one I am going to by just yet.
Just saw an “LED LCD” at Sam’s amazingly thin and bright. A flourescent backlight LCD looks fat and obsolete by comparison and uses quite a bit more energy.
VIZIO, SamSung, LG and a couple of other brands are what I’ve been looking at here. All get good feed-back from the ‘computer’ store people I’ve talked with.
It’s basically come down to back lit vs. edge lit LEDs. What i’ve read so far seems to favor edge lit LED LCDs.
OK...thats the kind of info I’m looking to find out. Thanks.
Wait a about two years and there should be OLED monitors and TVs available.
If you are asking this now, it’s safe to say you’re probably not an “early adopter”. (Not to worry, I went flat screen only about a year ago, LOL)
Hence, this probably isn’t something you expect to replace in 1.5 years. Eg; you want much longer life out of it.
The LCD screens have a high voltage power supply which is the primary failure point for these things. Otherwise, the life expectancy is near infinite.
Ergo, my preference is for LED, and would remain that way, unless some kind of lighting condition that I could not otherwise overcome forced me to use the other type. I’ve not encountered nor heard of such a condition, but that may not apply to you and your use.
LED’s seem to run a heck of a lot cooler than LCD (and esecially plasma) so that has to mean energy savings- and the picture is amazing on the LED TV’s I have seen so far
Really? I have read that the edge lit LED LCDs do not have the deeper blacks and some have flashlighting effects around the edges. The backlit LED LCDs have better black levels and can still be very thin. Of last years models the Samsung 8500 while expensive seems to be the gold standard. The back-lit models seem to back as close to a plasma picture as you can get in an LCD model.
Why the preference for edge lit?
The LED backlit LCD panels I’ve seen on several new laptops that have passed my way are just horrifically awful. They are grotesquely blue-biased and the contrast is abysmal. And nothing I did with the color controls could make anything better.
This is not surprising if you’ve ever seen any LED flashlights. It’s still impossible to make a true white LED. The best “white” LEDs still have a significant blue-bias.
For LED flashlights, who cares. But in LCD panels for computer work it makes a big difference.
As far as I’m concerned the whole LED back light thing is primarily a green scam. Yet another inferior technology used solely because it uses slightly less energy than something that actually works.
This might be an apples-oranges question, but how do LED/LCD TVs stack up against plasma? Thinking about the latter based on picture quality.
Still really nowhere close to a good plasma. The LCD panel technology is deficient and will never equal plasma in picture quality.
Well, yer basic C comes before yer basic E....sooooo......gotta figger LCD comes first, eh?
If you go to avsforum.com and go to the LCD section those techies are extemely knowledgeable and know all about black levels plasma is a bit more expensive but has the best black levels but their brightness fades as time passes
