Lev13than writes "An article in the Toronto Star questions whether the battle between LCD and Plasma is the next VHS vs. Beta: "LCD is now in plasma country, and this means war — a war some say plasma can't hope to win". Rationale for LCD's victory include plasma's burn-in vs. LCD's ruggedness, improved images and falling prices. While the Beta analogy isn't particularly helpful (since both technologies play the same content), the article does raise interesting points."

Laser TV — the Death of Plasma? 351 comments
spoco2 writes, "As reported in major news outlets yesterday in Australia (The Age, the Herald Sun), a new television technology has been developed which is touted (by the developers) as far and away superior to both plasma and LCD. From The Age: 'With a worldwide launch date scheduled for Christmas 2007, under recognisable brands like Mitsubishi and Samsung, Novalux chief executive Jean-Michel Pelaprat is so bold as to predict the death of plasma. "If you look at any screen today, the color content is roughly about 30-35 per cent of what the eye can see," he said. "But for the very first time with a laser TV we'll be able to see 90 per cent of what the eye can see. All of a sudden what you see is a lifelike image on display."' The developing company, Arasor International, is said to be listing on the Australian stock exchange shortly."

New Larger TVs Favor LCD Over Plasma 211 comments
Information Week is carrying a Reuters story examining the shift towards LCD technology in recent large-screen television models. Though some analysts acknowledge that plasma displays have faster response times over large surfaces, the industry seems to be betting that consumers will prefer higher resolution images over time. From the article: "CPT's Wu agrees that plasma panels, especially 50-inch and larger ones, do excel LCDs in some aspects of picture quality, but he says the sheer size of the LCD camp will help LCD panels overcome whatever drawbacks they have in a timely manner ...With the 40-inch-class market gradually taken over by LCD TVs, plasma models need to migrate to the market for 50-inch TVs and above, but demand is not as well developed there, analysts say. 'The United States accounts for more than 70 percent of demand for 50-inch plasma TVs and larger. In other words, there is virtually no 50-inch-class plasma TV market outside the United States,' DisplaySearch director Hisakazu Torii said."

Now the trick would be how to get such a model to compete with the existing model of disposable devices. It hasn't worked for printers even though everyone is aware that desktop inkjets and laserjets are a rip off. You can pick up a 8-10 year old office laser printer for only about double the price of a new cheapo laser printer, and the old "beast" might take up more space in your home but it will probably last another 10 years and be servicable. and you can usually put around four times more paper in it, so you don't have to fill it up as often or find a place to store your half-used reams of paper.
I don't know anyone who actually went out and bought an old laser printer in preference to one of the new junk ones. so I'm guessing this isn't working out either.

I have a Sony CRT-based HDTV, and I really would love a flat-panel big screen. I think right now I'd favor LCD, but that preference is partly based on hearsay about Plasma (supposedly high power and supposedly short life), not direct experience.
I have had direct experience with LCD, and I love it - except for the uneven fading of the CCFL backlights (maybe LED would improve this?), and the poor image quality when viewing non-native resolutions (which is improving with newer technology, and is mainly a problem only with PCs or SDTV).
I haven't really warmed up to DLP - poor off-angle viewing and relatively dim image - but I can see the economy in it.
So, I'm torn - each have strengths and weaknesses, but I'd hate to see one drop out simply because some information wasn't brought up.
I imagine if people knew that Betamax was capable of better image quality without breaking backward-compatibiltiy, it might have trumped VHS (okay, there was also the closed-source problem, and the legendary porn industry influence).

LCD backlights prohibitively expensive to replace? The fact is, they CAN be replaced, and aside from a few manufacturers who INSIST on gluing or epoxying the cases together, they are relatively easy to replace, and the tubes themselves cost anywhere from $2.00 to $30.00. Compare that to plasma, where to replace the screen you may as well just buy a whole new set (it's the equivalent of replacing a picture tube on a conventional television or monitor).
Buy a set based on:
- Response time
- color purity
- contrast ratio and black level
- Image burn-in possibility (a potential issue for static displays and console gaming)
Until OLED sets become available, Plasma will win color purity and contrast ratio hands down. LCD will win for weight/ease of installation and possibly versatility.

I looked at a ton of different makes and models for months before settling on this one. Let's see the pros and cons laid out for plasma vs. lcd.
Plasma: Pros
1. Relatively cheap at large sizes
2. Good contrast
3. Nearly perfect refresh, just like a CRT, so fast moving imagery doesn't ghost
4. Bright and viewable from all angles
Plasma: Cons
1. Eats alot of power and generates a ton of heat. Put your face next to one and it's like standing under a hair dryer.
2. Image burn-in is *still* a concern
3. Glass covering screen doubles as a mirror. Very distracting.
4. Looks really bad close up due to CRT-style pixel gates, can count the columns
5. Low native resolutions regardless of size. Most 42" and below only do 1024x768 native, which is a 4:3 resolution, so displaying a pc on one guarantees a stupid looking stretched desktop since the screen is actually 16:9 sized.
6. Fragile and delicate
7. Supposedly short life
Now for my friend the LCD.
LCD: Pros
1. Proven technology used for computers and other devices for years.
2. Light and durable, easily moved at nearly any size.
3. Contrast and black levels have improved dramatically over the last 3 years.
4. High native resolutions; most screens give you a true 16:9 ratio out of the box with 1366x768 being the standard.
5. Anti-reflective coated screens ensure that you're watching the movie instead of watching yourself eat popcorn. Similar to laptop and other LCD screens in that respect.
6. Some models feature user-replaceable backlights (mine does)
7. Latest screens have very fast (8ms or less) refresh times, no more ghosting or problems watching sports
8. Save quite a bit of power when compared to CRT or plasma screens
LCD: Cons
1. Expensive when you get into 42"+ territory
2. Can exhibit dead or stuck pixels eventually, sometimes this is user-repairable, sometimes not
3. Still not 100% 'contrasty' like plasma or CRTs, this is changing though
So the way I see it, an LCD is the clear winner. All of my clients bought LCD instead of plasma, even though they all tend to be thrifty and save money wherever they can. A trip to a very good home theater store, and you'll see why they (and I) chose LCD over plasma. It really is worth a few extra bucks.

"Expensive, pixels viewable with large screens, picture can fade over time, slow pixel response time can cause motion blurs."
Here's another view from Planar's Ali Gard:
http://blog.planar.com/embedded/2006/01/crts-lcds
An excerpt:
"LCD's luminance is controlled by the luminosity of the backlight / edgelight. The backlights in LCD monitors are almost always CCFL (cold cathode florescent lamps). The life of the backlight is determined by how long it takes until the lamp reaches half of its original luminance. Similar to CRTs phosphors in CCFL's age and their efficiency declines. LCD's don't suffer from flicker, or image burn just a few years ago that time was about 30,000 hours. Newer lamp technology has increased that time to 60,000 hours to reach half brightness."
That puts it at 3.5 to 7 years (if you accept the manufacturer's claims). What he doesn't address is that the CCFL will fade unevenly which is most obvious in large panels.

Presuming one watches TV on average 6 hours a day - with 2.5 years guaranty - that would make 10 years of lifetime. 10 years later I'm sure it would be possible to replace cheaply the panel with new one - just like it is happening now with CRTs.
CRTs are also prone to degradation - just like plasma and LCD. It's just the quality of CRT sucks (HD LCD/Plasma really provide better viewing experience) so nobody watches them too much. (After coming to IT, I barely can look at CRT TV at all: 50Hz just hurt my eyes too much.)

Sure, it's the size of a typical european car and weighs about the same but, for picture quality, there's a reason why most stores quietly moved it away from the much higher markup flat pannels they'd rather still be able to sell.
Granted, the follow on model (34XBR970) actually dropped picture quality (from 1440 horizontal scan lines to something like 1100) to get set reliability up. The point still remains: For reference picture quality, people still seem to be picking CRT after a decade of promises about the latest flat pannel having the greatest ever picture.
It's true the average consumer doesn't see that. Then again, they're remembering their $199 CRT of yesteryear and comparing it to a $1,999 flat pannel. Compare the budget end of any line, even an overall superior one, to a line that barely has a budget line and typical models cost ten times as much as the other's budget end and, sure, it'll give you a skewed result.

I'm not sure what you mean by "it's a pain to keep a quality image" and "difficult to maintain properly."

Wrong, Entrenched Ideas on Technology (Score:5, Informative)
As a writer of an article, one should do more than research the televisions of one company and base all aspects of technology on it. That company, would be Sony as indicated by the author of this article as it is the only manufacturer that is being represented.
This article is filled with entrenched ideas of plasma technology from about half a decade ago, when LCD televisions were prohibitively expensive and small.
It does not need to be restated that this article has no resemblence to the Beta vs. VHS wars as all televisions will continue to be able to display a standard picture, but here are the wrong ideas being perpetrated by this author.
Plasma's burn-in has been eliminated due to algorithms developed by both Samsung and Panasonic to essentially shift on-screen images ever so slightly to avoid a single image to stay in one place. In fact, even if you blasted a pure white image on the screen to purpose for a day (a standard accident, perhaps?) then the technology can even cure that over a day period of standard use.
Black bars will not cause burn-in on today's plasma televisions. Television station logos that sit non-stop in the bottom-right corner are the only culprits. Even most stations have figured out to shift the logo a bit or make it transparent enough that the older plasma television crowd will not have burn-ins.
Sony abandoned its plasma television technology because it just couldn't win. Sony was using glass from another manufacturer, which is a very expensive part. Consumer Reports and CNet routinely choose Panasonic plasmas as the very best because they manufacture the key plasma television components. Likewise, the article states that Sony abandoned it in favor of LCD technology. Sony also abandoned the tube television technology which was a cornerstone of the company's name. One would imagine a specialist, nay a leader, in tube television technology would have been most adept at establishing plasma technology.
Plasma televisions are not hot. Hovering one's hand above the vents of plasma televisions today reveal no more heat than a standard television, except suspiciously on brands such as Sony or Akai. Go through a Best Buy and feel the lack of heat emanating from a Pioneer, LG, Samsung, or Panasonic. In fact, Samsung did use to have fans to cool its plasma, but over time it has been eliminated.
Now for some editorializing... I pass by three plasma televisions every day in a work environment. A Samsung plasma hangs suspended from a ceiling displaying a static computer display giving graphical and textual read-outs. The display never changes interface except a screensaver comes up every thirty minutes. It does not have burn-in when somebody gets caught surfing the web on it by accident (I always find that one funny). A Sony plasma hangs in the boardroom, it is hardly on except for a teleconference, and it works day in and day out with just a face on it most of the time. A Panasonic plasma plays video non-stop in the breakroom and is only turned off at night. That display is smaller than the rest at 42 inches, but it is phenomenal color-wise and it hasn't failed either. Plasma technology is not terrible. It's very good. LCDs do not offer lighter weight or thinner enclosures than plasma (so far). LCD panel televisions will defeat plasma in the situation where it becomes thinner, lighter, larger, and more beautiful displaying images (this encompasses the entire image quality and motion playback attributes) in a fast enough time with a matching price to plasma on size. The problem is that plasma if you look online is far cheaper than an equivalent LCD panel television. Retail chains are making a load of money off of plasma units in-store. LCD television technology is priced exactly as it is worth in both on and off-line venues.
I'm just glad the author of the article didn't compare this to the Wii vs. Playstation 3 war or the Zune vs. iPod war.

Plasmas vs LCDs, I'm rooting for Plasma (Score:5, Informative)
I wouldn't touch LCDs over 40". I work in retail and I hear both sides of the story. Sharp and other brands like Sony push LCDs through like mad, while Panasonic is primarily a plasma brand.
Power consumptionPlasmas and LCDs use a comparable amount of power. A 42" Panasonic plasma uses at most 350W (TH42PA60). An LCD of the same size would use about 300W at most. The difference is that the plasma only consumes 350W when it is displaying a full white picture. If it is a dark scene, it consumes less power (since the pixels are not arcing as often). LCDs consume a rather fixed rate of power since the backlight is always illuminated.
Brightness
Plasmas work by emitting light, whereas LCDs work by blocking light. Since LCDs block light, it is difficult to stop light from leaking around blocked areas. Philips' latest LCD is capable of dimming certain areas of the backlight, but the leaking is still there. Plasmas on the other hand won't get leaking. In fact, in darker scenes the detail will always prevail over an LCD.
Lifespan
Panasonic now boast that their plasmas will last 60,000 hours, which is now comparable to LCDs. Like LCDs, plasmas lose brightness over time. Panasonic's 60,000 hour figure is the length of time it takes to become half as bright. Philips, Sony, Sharp and Toshiba all boast similar figures for their LCDs and plasmas.
Price
Well, here it becomes weird. Panasonic invested a huge amount of serious dollars into a new factory which aims to pump out hundreds of thousands of plasmas each year. A 42" plasma is generally cheaper than a 42" LCD. The difference is that it is immensely expensive to create large LCDs that will not have poor constrast and brightness and remain responsive (i.e. 10ms or less). Plasmas on the other hand "prefer" to be big. It is impossible to create small plasmas because of the size of the pixel. So if the TV screen size gets bigger, the price increase from plasma to LCD will too.
My biased opinion
I work for a company which exclusively sells Fisher & Paykel, New Zealand's largest whiteware manufacturer. Until recently, F&P were Panasonic's importers in NZ, until they were big enough here to take care of themselves. They still work closely together (one of F&P's double ovens has a built in Panasonic microwave) but because of their reputation together and because of where I work, I sell more Panasonic appliances than any other brand. Panasonic's primary interest in terms of TVs is plasma, and from all the evidence that I was given from all brands saying that x was better than y, Panasonic's was the only evidence that remained consistent over the course of 3 or 4 years. It concluded for anything big (say, 42" or larger), go plasma, for anything small, go LCD.
I cannot see Plasma TVs failing. Over the last year, Panasonic's TH42PA50 plasma was the top-selling TV of any classification throughout Australia, and the top-selling 42" TV in New Zealand. The PA60 model boasts even more features for the same price.

That just isn't so. The super-high-end TV market is driven by the sports fanatics. For every one wall-sized unit sold to a movie nut, ten are sold to (American) football nuts.

Re:I bought a Rear Projection TV (Score:5, Informative)
Why?
1. Rear projection CRT may look the best, but they are way too bulky for the space. I wanted a sleeker TV, not a bigger one than my old standard CRT.
2. My wife sees the rainbows on DLPs. It's less obvious with higher-priced models (where the color wheel spins faster), but it renders them unwatchable for fast content (like sports or action movies) for her.
3. Plasma versus LCD came down not to their performance with hi-def content, but with their performance with standard content. I've had my plasma TV for more than a year, and most stations I watch are still standard def. In my opinion, standard def TV looks better with plasma than with LCD. I looked at lots and lots of TVs, and I switched them in the stores to standard def broadcasts instead of leaving them on the hi-def channel the retailer wanted to show. Of course standard def content looks worse on a big-screen TV than on a small TV, but the static and artifact pixels were far more visible with LCD than with plasma.
This whole discussion is silly, anyway. Both types of TVs can play the same content, as can rear-projection TVs, DLPs, and even those polymer TVs in the Slashdot article yesterday. There's no reason they cannot all co-exist in the marketplace. As long as there are people like me who dislike LCDs, there will be a market for them. (I don't even use LCD computer monitors - CRTs still look so much better it's unbearable.)

Funny you should say that... Samsung finally shipped their LED-based DLP a few weeks ago.

I don't know if they have removed the fan altogether, but they have removed the color wheel (one less thing spinning at 10k+ RPM...) and the LEDs generate a LOT less heat than the traditional bulb, so I'd imagine it's effectively silent.
Going a bit off topic (well, not really, we're talking TVs!) Sony was showing off a prototype SXRD (ie LCoS) TV at CES 2006 that was about a foot deep (they had it hanging on a wall). Combine these innovations in projection TVs (true 1080p DMD/LCoS chips, LED lamps, thin cabinets, etc) and amazingly they may start taking some of the plasma/LCD market segment, ie low footprint HDTVs - especially in the 50"+ range, where there is a huge price advantage for projection TVs.
