What is different between plasma tv and LCD tv?
Answer:
Well, PLASMA is a big power hog, runs hot, operates like a flourescent bulb does and is heavy...but it hangs on a wall real NICE.I guess that's the only reason I would buy plasma.if I needed to hang it on a wall.
NOW LCD is VERY RUGGED.runs cooler, uses less energy, is a tried and true technology, only one other type of TV is more rugged and that is the CRT Projection TVs.so it runs a close 2nd in reliability. Also, they have smaller LCDs that are MORE reliable than the LCD projection TVs..and those can be wall mounted !!
Overall, LCD is not going to kill your wallet..
But I chose CRT projection only because I'm Cheap and I don't want to have to repair my Projection TV set after spending hours repairing Plasmas and LCDs and DLPs..
I'm not sure of the science behind the plasma but an LCD is litteraly liquid crystals. I prefer LCD in most spaces. Plasma screens have to much glare because of the smoother surface on the screen. They are good in a room which no outside light reflects on the TV. LCD still has a very sharp image without the glare.
Essentially the difference is in how they actually display the picture.
LCD's use a thin layer of crystals (like you'd have on a digital watch) between two panes of glass to create the picture. An electrical current stimulates the crystals which then change color, the pattern of the current determines the color of the crystals and therefor the picture that's displayed.
Plasma TV's work similarly but instead of having a thin layer of crystals it has Xenon and Neon gas contained in hundreds or even thousands of tiny cells. When the electricity excites the gas it changes colors which determines the picture.
I've not priced either but I assume that LCD's are a little cheaper at the moment because they've been out a little longer. I think.
LCDs give sharper picture quality as far as I know, but as I said I haven't been keeping up with the newest technology.
See below for the actual "how" and "why" an LCD or Plasma TV works.
Plasma tv's are much more expensive than LCD, and don't have near the life expectancy. Plasmas have to be level, can't be moved, jarred, and can be ruined by pressing on the screen(must have protective shield). Picture quality may be some better, but not worth the extra costs(my opinion). I have a DLP that gives LCD'S a run for the money...1/2 cost of LCD; 1/5 cost of plasma.
Basically, A plasma's image is created by heated inert gases embedded between two glass panels. Now in terms of quality, the highest resolution available is somewhere around 1366X768 pixels, or regular 1080i high definition. Plasmas are relatively cheaper than flat panel LCD TVs (anywhere from $800 - $3500) because they are cheaper to manufacture and their life expectancy is rated in terms of hours. Plasma sets are said to have about 60,000 hours which comes out to be about 20 years (on average). The one thing they leave out is that plasma sets suffer from pixel loss, which can happen early in their lives. One more thing you would have to look out for is image burn-in; that happens when a static image (i.e. the ESPN scoreboard at the bottom of TV screen) stays on consistently over long periods of time. The nice thing is that they are flat and mount nicely to a wall, but the screen itself is glass so glare may become a problem in well-lit rooms.
LCD come in two types: projection LCD and flat-panel lcds.
Projection lcds are basically the "new" big screens. They longer use the three tubes to produce an image, instead they run off of lcd chips that filter light coming through them. They are less tall, not as deep and are able to deliver a high definition picture. The highest resolution available for these is is 1920X1080 which is what is now considered to be true high definition. If you have ever seen a blu-ray movie then you know how good the quality is. "True" high defintion or 1080p is not really that big a deal right now beacase TV stations are only broadcasting in in 1080i. I personally though, would recommend that you purchase a 1080p tv because youll be set for the many years to come. Durability-wise, it is probably the most durable of the three types. The only thing you really need to worry about with this type of set is the light bulb inside that helps produce the image. Those are usually replaced about every 5 years, so it would be a good idea to get a service plan with the tv, becasue that will be covered. Price-wise, they run about the same price as plasma sets, so it comes down to whether you want your tv mounted on the wall or not. If thats not a big deal, then I would stick with a lcd proj.
Finally, lcd flat panels are the most expensive ($1200-4500) but definitely the nicest sets. They are by far the sexiest looking, and come in true hd quality. Now as far as durability goes, they outlive the plasmas and may be just as good as the projection version, if maintained properly. The quality of the picture is the best due to the fact that the screen has no glare, you get a ful 180 degrees of angle wiew and now some are now 1080p capable. If you have the money, and want to make a bachelor pad out of your home, then this is the way to go. Good luck and I hope this helps :)
P.S. Oh, I almost forgot to talk about the economy of the three types. Plasmas consume the most energy by far, followed by the LCD flat panels then the projection. Youll be fine with any of the LCD sets.
