LCD TV DEAL

   CONTRAST / BLACK LEVELS
   ADVANTAGE: Closer than a year ago, but still Plasma. LCD TV manufacturers have made great improvements in black levels and in many cases have managed to match the contrast ratio of plasma displays. However, Plasma displays still maintain a clear advantage in this category due to fading blacks when viewing LCDs from off axis. For scenes with a lot of dark and light images shown simultaneously – as with content originating from DVDs, video games, and NTSC TV signals – plasmas still consistently outperform LCD TVs.
   COLOR ACCURACY
   ADVANTAGE: Preference to plasma but depends upon room light, manufacturer and model. Plasma color richness and naturalness will prevail in rooms with lower to normal lighting. LCDs will be better in very brightly lit rooms due to their inherent anti glare technology and brightness.
   VIEWING ANGLES
   LCD TV manufacturers have done much to improve their displays’ viewing angles. The substrate material on newer-generation LCD models by Sharp and Sony has helped to expand those units’ viewing angles, though they still have some ground to cover before catching plasma. Expect the best LCD HDTVs to have between 120 and 130 degree viewing angles.
   ADVANTAGE: Plasma
   FUNCTIONAL CONSIDERATIONS
   COMPUTER USE
   LCD flat screens display static images from computer or VGA sources extremely well, with full color detail, no flicker, and no screen burn-in. Moreover, the number of pixels per square inch on an LCD display is typically higher than other display technologies, so LCD monitors are especially good at displaying large amounts of data – like you would find on an Excel spreadsheet for example – with exceptional clarity and precision. For the same reasons, LCD TVs will also be a slightly better template for video gaming.
   Plasma technology has increased anti burn in tactics as well as computer and static signal handling. There are still issues with each depending very much on the model and manufacturer. For example, most EDTV plasma displays do not handle a computer input well and product a very jaggy image when viewing static images from same. Users may want to consider a commercial version plasma if their application calls for a lot of computer use.
   ADVANTAGE: LCD
   FAST-MOVING VIDEO PLAYBACK
   Plasma gets the nod here because of their excellent performance with fast-moving images and high contrast levels. There are still some 2nd tier manufacturers whose plasma product displays some phosphor lag, a drag time in scenes changing from bright to dark.
   While the “response time” of LCD TVs has markedly improved in the last couple of years, they still suffer from a slight “trailer” effect, where the individual pixels are just slightly out of step with the image on the screen. During fast moving sports scenes, the most discerning eyes can detect this slight motion response lag.
   ADVANTAGE: Plasma
   HIGH ALTITUDE
   There is a reason LCD flat panels are the preferred visual display units for use on airplanes: LCD TVs aren’t affected by increases or decreases in air pressure. Their performance is consistent regardless of the altitude at which they’re utilized.
   This is not the case for a plasma. The display element in plasma TVs is actually a glass substrate envelope with rare natural gases compressed therein. So, at high altitudes (6,500 feet and above), an air-pressure differential emerges, which causes plasma displays to emit a buzzing sound due to the lower air pressure. This noise can sound rather like the humming of an old neon sign. NEC has been effective in producing several plasma models that are rated to 9,500 feet.
   ADVANTAGE: LCD, at 6,500 feet and higher.
   LONGEVITY
   ADVANTAGE: Even, depending upon manufacturer quality.
   SCREEN BURN IN
   ADVANTAGE: LCD, though not as much a concern as it was a year ago.
   PRODUCTION SIZE AND COST
   ADVANTAGE: Plasma, though the playing field is leveling. Even though production costs and retail prices have come down for both technologies, plasma still has the edge as far as production cost and capacity go.
   POWER CONSUMPTION
   Because LCDs use florescent backlighting to produce images, they require substantially less power to operate than plasmas do. LCD TVs consume about half the power that plasma displays consume. The reason: Plasmas use a lot of electricity to light each and every pixel you see on a screen – even the dark ones. Though plasma manufacturers have improved voltage consumption requirements a plasma TV will consume around a third more power for the same size display.
   ADVANTAGE: LCD
   PRICE AND RESOLUTION
   LCD HDTV displays will have a higher resolution per same size comparison than plasma. The lowest resolution of a 40 inch LCD will be 1366 X 768 – easily full HD resolution in 1080i or 720p. A 42 inch HD plasma has a resolution of 1024 X 768. While this is not truly an HD resolution, it’s close enough so that it’s difficult to know the difference. A 50 inch plasma TV will have a res

2. chicagoi Said,

   plasma tv’s use a neon-xenon gas that is sealed in plasma, it is then electrically charged when you’re looking at television and the gas gets warm and changes color accordingly so you get that extremely vibrant color from the phosporuos which creates an image also called a pixle. LCD’s use a crystal that requires a florecent light to aid it in creating an image, LCD’s use less energy and are generally smaller and lighter. Plasma Tv’s advantages: Sharper images, deeper color, better contrast ratio, available in larger screen sizes, better color accuracy and it is less susceptible to lag between frames. Plasma Tv’s disadvantages: Uses more electricity, can overheat, the gasses can burn and create black spots on the screen, shorter life span than LCD’s and not that good with static images. LCD Tv’s advantages: longer lifespan, lower energy cost, usually lighter than plasmas, wall mountable, more brightness over plasma, since it does not require the heating of gasses. LCD Tv’s disadvantages: more expensive, if a pixle burn out you will need to replace the entire screen rather than the single pixle, usually not bigger than 72 inches, not as good as tracking moving objects (mainly for sports), lower contrast ratio, and less vibrant looking colors.

3. Insolentleet aka breaking Said,

   LCDs are getting better all the time.
   Plasmas have little tiny “light bulbs” of each color for each dot on the screen. Plasmas are bigger because they can only make the light bulbs so small. They use more electricity than LCD. The colors are better and can be seen from side angles
   LCDs have layers of each color that allow a light from behind to shine through of a given color for each dot. They are smaller because making the screen with larger dots would be all splotchy. LCDs still have issues of not seeing them well from side angles and fast motion cannot switch the dots fast enough and the picture blurrs, BUT they are getting better. Tvs that say 120 hz mean the dots switch faster and won’t blurr.

   Kudos to That G for the link. In addition to the information on there, on a personal note I’ve found my el cheapo LCD ($800) to have a better picture quality than the Plasma I paid $2000 for several years ago (fyi, if you ever find yourself moving interstate, a plasma has a crap resale value, I got $120 for mine and it was 18 months old! ) My LCD is a lot bigger than the plasma and I love it!
   I really don’t know anything about the technical side of it but there’s a layperson’s perspective for you.

   Plasma is better for dark picture, LCD is better for bright, also LCD lasts alot longer and doesnt burn in picture.
   This is best TV you will find for your money. The LG 47LG70 47-Inch 1080p 120Hz LCD HDTV, and this is the cheapest and most reputable place to buy it, Amazon is AWSOME and they give you FREE SHIPPING!! This if defiantly the best model you can buy. And its not too expensive.

   LCD is better than Plasma trust me. Its all about picture quality. LCDs last longer.
