- shabumike, on 10/31/2007, -2/+31LCD uses less energy than CRT televisions or monitors, plasma is on its way out anyway.
- monkeyrun, on 10/31/2007, -0/+18hmm.. strange article, why don't they talk about LCD?
- pdaz, on 10/31/2007, -0/+17Plasma has to excite the electrons and make them vibrate and emit light. Similar to CRT. A 70" plasma has 4 times the screen area as a 35" CRT. Rest is math.
- Tserk, on 11/01/2007, -1/+13Big TVs are still awesome.
- carpespasm, on 11/01/2007, -1/+12hmm, bigger tv = more energry to power? NYAHH......
- allaboutdatiki, on 10/31/2007, -1/+10Gotta love the Sony HDNA ad sitting up there in the right corner of the page ...
- RadiantBeing, on 10/31/2007, -2/+9Or you can buy an LCD TV and use less electricity while enjoying flat panel goodness. Why so glum?
- Yeenoghu, on 10/31/2007, -1/+7The article was amazingly lacking in depth, so it's no surprise they didn't get into the differences between plasma (typically use a lot of energy) and LCD (not so much energy) screens. There are a lot of factors that go into flat panel energy usage that weren't discussed, down to use of power savers on plasma screens, which typically result in dimmer pictures, and the type of backlights in LCDs -- LEDs performing better than CCFLs, for example.
- Hickeroar, on 10/31/2007, -0/+4I think the author did an awful job in distinguishing between LCD and Plasma. Plasma = hog. LCD = not... Plasma = burn in just like a CRT, LCD = VERY VERY rarely do they EVER have burn in. Plasma = not very long "tube" life & expensive replacement. LCD = much longer life & cheaper backlight replacement.
Plasma = higher contrast ratio though... - colonelbuckshot, on 11/01/2007, -2/+6Buried. Why is he talking about Plasmas? All the newest and baddest TVs are LCDs, splendid 50" ones.
LCDs consume much less power than Plasmas or CRT. - ZakNicola, on 11/01/2007, -9/+13consume consume consume
It's like when the SUV's first came out, everyone had to get one. Few years later, everyone starts crying about how much gas they waste.
You too can have the American Dream! Just spend more, and buy my *****! - p0ss, on 11/01/2007, -1/+5Australia is bringing in a new energy rating system. Under this system any TV that scores less than 3 stars will not be allowed to be sold after 2011.
That means all current TV's LCD's Plasmas and CRTS will be effectively banned. The current wave of televisions are incredibly power hungry, regardless of wether they are lcds or not.
Laser TVs and OLEDs are not nearly as consumptive - colonelbuckshot, on 10/31/2007, -0/+3The last good store I went in, there were no Plasmas on sale. All the best new TVs are LCD. They have better picture, don't burn out and consume less power.
- JupiterSSJ4, on 10/31/2007, -0/+2most lcd screens bigger than 40" use at least 260W, the one plasma that consumer reports actually gave a perfect rating (its first perfect rating) uses over 600W. Totally ridiculous!
- jolt459, on 10/31/2007, -3/+5Who cares about energy, as long as I got my foot ball game playin, my wings in my hand, my popcorn on the side, and some beer, I'm set for life!
/sarcasm/ - guyincognitoo, on 10/31/2007, -0/+2I don't know about you, but I don't plan on buying yet another TV anytime soon.
- inactive, on 10/31/2007, -1/+3My tv uses < 200 watts
However, it takes 30 seconds from the time you press the power button until the time you can actually see anything.
On the other hand, it does run linux. (I saw the GPL in the back of the manual) - shad0w, on 10/31/2007, -1/+3Well if you really want to get technical, LCDs have cleaner whites and cripser colors while Plasmas have better blacks and can better handle motion. Regardless, sales of plasmas in the 40" range have been slowly shrinking while LCDs in the 40" range have expanded.
- ManOfCube, on 11/01/2007, -0/+2Sony TVs use several GPL libraries for displaying images. Some of them also have kernel 2.4 but I don't know what for.
- shad0w, on 11/01/2007, -0/+2Correction, *IF* OLED becomes the standard. Remember SEDs? Two years ago SED TVs were the new standard, and now they're vaporware. LCDs and Plasmas are established, cheap technologies and it will be a long while before something as experimental as OLEDs surpasses them in sales.
- zonk3r, on 11/01/2007, -0/+2I noticed that Samsung's DLP systems also have GPL licensing info in the back of the manual. I'm guessing they use it for something similar.
BTW, Samsung's DLP systems with LED backlighting are pretty good for energy efficiency. - grumpyrain, on 11/01/2007, -0/+1precisely.
From memory you are comparing about 0.27W / square inch for LCD to abour 0.32W / square inch for CRT or plasma. - zonk3r, on 11/01/2007, -0/+1I think you meant to say:
It's funny WHEN the Digg comments have more intelligent information... - p0ss, on 11/01/2007, -3/+4LCD's are still power hungry
- mastertop, on 10/31/2007, -1/+2That's a Linux media center?
- slayerab, on 10/31/2007, -2/+3It's called the rat race
- shad0w, on 11/01/2007, -1/+2...And are also way more expensive and aren't ready for the market. I'm sure we'll see low-power LED backlit LCDs before we see laser TVs and OLEDs.
- dvdchris, on 11/01/2007, -1/+2That's like two paragraphs of information. No depth to the article. MUCH better article at cNet about this- http://reviews.cnet.com/4520-6475_7-6400401-2.html - it even compares 54 TVs power consumption.
- bitmanx, on 10/31/2007, -0/+1When you watch HD on a plasma at nite I don't give a rats ass what it costs..
- p0ss, on 10/31/2007, -1/+2LCD will be on the way out soon. Laser TV and OLED are the way of the future.
- grumpyrain, on 11/01/2007, -0/+1Australia is shutting down its analogue TV signals too next year sometime. Yeah, right ....
- Grivako, on 10/31/2007, -0/+1i thought the idea of having a huge ass tv was that everything was bigger and better, including your light bill
- grumpyrain, on 11/01/2007, -0/+1Compare apples with apples please. With all else equal, an LCD TV will consume about 10% less electricity than a CRT TV of the same screen size. The real issue here is that people are significantly upsizing their TVs in the process, which roughly follows a square relationship (double the screen size, quadruple the consumption).
Also, a sales trick that is often employed is to turn the brightness up to exaggerate how sharp the image looks and the colour definition. Make sure when you bring it home you reduce the brightness to an appropriate level. - fraggle35, on 10/31/2007, -0/+1I was really pleased that I'd got a Land Rover when I bought my 52" LCD, Didn't need a big truck to deliver it, it went straight in.

Bah. My LCD consumes half the power of the CRT, and runs less hot. It's all about losses, folks. - floorman56, on 10/31/2007, -0/+1But I unplugged my cell phone charger when I'm not using it so it's all good
- Elliuotatar, on 11/01/2007, -1/+1Maybe you should try doing a comparison. They may be brighter, and have darker black levels, but the picture has tons of noise. They also put out tons of heat, suffer from burn-in, and tend to go bad after a few years.
SED is where it's at. As soon as SED comes to market, LCD and plasmas will go the way of the dinosaur. - trer, on 11/01/2007, -1/+1This will not be an issue once OLED becomes the standard.
- chingy1788, on 11/01/2007, -1/+1im betting the brightness on the LCD is on max, displaying a black screen
and the brightness on the CRT is on minimum displaying a black screen - Plammox, on 10/31/2007, -0/+0(Replying to the right post this time)
My ½ year old Samsung 32" LCD (720p) uses 152W. A 32" CRT with 720p and HDMI (yes, Philips still made them ½ a year ago, when I last checked) uses less than 100W. So your assumption just isn't valid. - rickmarnon, on 10/31/2007, -0/+0everything starts out on fire then people start to complain about them,,,
- krayzee911, on 11/01/2007, -1/+1It's funny that the Digg comments have more intelligent information than the article and its comments. The article itself is a series of questions without answers followed by incoherent ranting and gibberish.
"How much radiation is being turned out?? Whats this going Green?? Is it only for the people out here? Was in The Sears Store,Wilkes-Barre,Pa, counted over 100 TV sets on. Boscovs,Wilkes-Barree,Pa over 60 sets on Can go , on and on, Same thing in almost all stores. When are they going to start doing there part to save energy."
Whoa there, Tex! Sounds like it's about time for your medication... - Plammox, on 11/01/2007, -1/+0My ½ year old Samsung 32" LCD (720p) uses 152W. A 32" CRT with 720p and HDMI (yes, Philips still made them ½ a year ago, when I last checked) uses less than 100W. So your assumption just isn't valid.
- fuzzynyanko, on 10/31/2007, -2/+1I agree with LCDs. My 15" LCD monitor uses like 15 watts of power, and the thing is old.
- x2dx, on 11/01/2007, -3/+2...
- wdehner, on 10/31/2007, -6/+5How are plasmas on their way out? Its more like LCDs are on their way up. More work is being done to actively develop LCDs and add more features versus plasmas which have already been there for a long time. If you compare picture quality of a plasma versus an LCD side by side plasma's will always win. The blacks are blacker and the whites are whiter, etc. Try doing a comparison sometime in a store and you will see.
- p0ss, on 11/01/2007, -3/+1you obviously dont live near a power plant
- trogdor282, on 11/01/2007, -4/+1Idiot.
- x2dx, on 11/01/2007, -6/+3electricity is cheep
