From an efficiency standpoint measured in mw per square inch, the order from most to least efficient is:

1. rear projection
2. LCD
3. CRT
4. plasma

Here is a good summary that I believe is as correct as you can make it:

The 45 watts that a 20-inch LCD TV uses is about what it takes to charge a notebook PC, while the 55-inch plasma's 507-watt consumption is closer to that of a large refrigerator. Of course, some sets, such as Panasonic's 50-inch TH-50PHD8UK plasma, can be more efficient than others. It's the same size as Maxent's MX-50X3 plasma, but it used a little more than half as much power when we engaged its power-saving mode.

Size matters as well, so we divided each set's power use by its screen area to get a watts-per-square-inch rating. This way, small and large screens can be compared. While there is some overlap, the TVs we tested form neat groups based on technology:


Microdisplay rear projector: 0.11 to 0.15 watt per square inch
LCD: 0.16 to 0.41 watt per square inch
CRT: 0.25 to 0.40 watt per square inch
Plasma: 0.30 to 0.39 watt per square inch


If power efficiency is all you're after, the clear choice is rear-projection technology, but these sets rarely get as bright as the others. While CRTs and LCDs are brighter, they are currently limited to about 36 and 40 inches, respectively. Of the four, plasma screens are generally the most power hungry, but on a square-inch basis, they are roughly equivalent to a large CRT set. Also, newer TVs are likely to be more efficient than older ones, and new technologies promise to make TVs more efficient (see "The future of TV power").

60" SXRD Altho I should have gone for the 70"..

 

unplug the drug

 

How thick is your plasma? My LCD is only 5.25".

the plamas definetly have the best blacks but my friends got mild to moderate burn-in from playing Madden on his PS2 and the salesman warned me of the same thing. I guess if you don't play games on it it would be a better choice but I've still heard issues about long term issues. LCD have no problems going 10 years+ and Plasmas still are reporting under 6 years.

 

52 Mitsu. DLP... i didnt really care for HD until i got this tv. WOW I also like the fact that the bulbs can be changed without much effort.

 

 

Here's some info I've found when I was researching Plasmas.


Most, if not all, Plasma displays suffer from some sort of image artifacting while the "old school" analog CRT displays do not. Many new Plasma TVs can produce a very good picture with HD or DVD sources. Plasma TVs with bad picture quality suffer from color banding, color dotting, and image artifacts with any source that most anyone can see with side-by-side comparisons done at the store.

The bane of Plasmas (and most new TV technologies out now) is medium-dark to dark scenes in program material. Many Plasmas cannot display the information correctly and instead display a mush of color bands, odd contours, and sometimes just the wrong color entirely. Plasma makers are getting better at improving this issue, but it is still an issue.

HDTV and DVD sources will look better than cable or satellite simply because there is more data in the picture with DVD and HDTV. When image processors have more data to work with, fewer artifacts will be made.

The reason old-school, interlaced, direct-view CRT TVs look better with standard-definition sources is that the interlacing and smaller size is actually hiding a lot of imperfections. With today's much larger, progressive-scan TVs you're simply revealing how bad standard-definition sources are, and viewing them much larger than they were intended.

 

I currently have a tabletop rear projection. I like it alot but if I had the money, the LCD would be in its place.

 

Y'all need to keep up on the CES (Consumer Electronics Show) announcements. Happens each second week of each January of each year.

Engadget's got a good overview:
http://www.engadget.com/category/ces/

The reason I bring it up is that there were a couple of 100" LCDs, the largest "Shipping LCD in the world" (100", $70k) and the current "largest LCD in the world" (not shipping, no price) at 108".

Also, don't miss the new OLED displays... The color is INCREDIBLE. That's a 1,000,000:1 contrast ratio:

Lol.. Can't think of anything we humans can detect at 1ppm!!

Not even Arsenic is dangerous in those ratios. uhh... maybe lawyers, but I digress.

 

1080p lcd

 

i still love my crt monitors, so i voted crt. as for tv's tho, i suppose lcd.
