What is the difference between LCD and Plasma?

Plasma -  A popular display technology, employed by many state-of-the-art flat-panel TVs, that produces colored light at the screen surface rather than projecting a separate light source through or off of other elements to conjure a picture. A plasma "screen" is actually a dense network of individual cells, three for each pixel of the display (coated with red, green and blue phosphors, respectively). Each cell is impregnated with a rare-gas mixture and connected to an individual electrode. When the electrode for a given cell is charged with an electrical voltage, the gas is converted to a plasma state and emits a burst of ultraviolet light; this in turn causes the phosphors to react and produce bright visible light at the pixel level. By varying the voltage and intensity of the electrical charge, the proper combination of red, green and blue light is produced in each pixel to combine into a bright, colorful composite image.

LCD - (liquid crystal display) Display system used on many electronic products including clocks, answering machines, handheld organizers, camcorders and personal computers. Liquid crystals are sandwiched between two glass plates. Minor temperature variations are introduced to particular points in the display using pinpoint electric charges, illuminating the crystals or causing them to change colors in predetermined patterns.

Plasma TV technology for large TVs is older but there isn't much room for improvement.  In general, they do a better job with displaying dark/black colors and have better response times when viewing fast changing pictures.  Plasma TVs are generally heavier and use more power than comparably sized LCD TVs.  Older plasma TVs were prone to burn in if the image did not change on the screen.  Newer plasma TVs have picture shifting that will subtly move the picture if it senses that it has not changed over a certain period.  A plasma picture will lose its contrast over time, just like the older Cathode Ray Tube (CRT) TVs do.  Early plasma haters said that they would only last for 5 years.  You know find people predicting lifespans more like 20 years.  The plasma TV viewing angle is great, meaning that you have a great picture looking at the screen from areas other than straight in front of it at eye level.

LCD technology for large TVs is relatively new and the first were very expensive when compared to plasma.  Prices are now comprable.  LCD TVs continue to get better at displaying the dark/black colors and their response times are getting better.  Nobody wants to watch blurry sports because the TV can't keep up with the motion.  LCD TVs are lighter in weight and use less power than comparably sized Plasma TVs.  OCD TVs do not have burn-in if the picture does not change at all for a long period of time.  LCD TVs can suffer from dead pixels (black spot) or stuck pixels (bright spot) over time.  The LCD viewing angle is less than plasma, meaning that your picture degrades after you reach a certain angle to the left, right up,or down from the middle of the screen.

LCD means Liquid Crystal Display.  These sets work just like your laptop screen.  The benefit of LCD is that they are available with matte finish screens which reduce glare, can be matched up to 120hz sources like blu-ray seemlessly, and are available in sizes below 42".  The also make fantastic computer monitors, no matter what the size.

Plasma works in theory like a flourescent light bulb.  There are gasses sandwiched between two panes of glass.  When charged with electricity, these gasses emit light.  To dispell some rumors, no the gas cannot leak out, burn in is no longer an issue with plasma, and plasma is ok even if you have alot of natural light in your room.

When trying to decide which technology is right for you.  You just have to go and look at them side by side.  Think about what you like to watch.  For instance, if you are a sports fan, plasma may be the best.  If you have a blu-ray player, then maybe a 120hz  lcd is right for you.  

Dont forget that with a HDTV, you only get out of it what you put into it.  If you want it to look like it does in the store, you MUST have an HD source (HD cable or Sat, blu-ray, etc) and you will need to spend some money on accessories like the right cables to get the best performance.

Both LCD and Plasma are amazing technologies and depending on what you are watching have killer picture!

Hope this helps!

Answer 3

The difference between LCD and plasma television is one that you should research before making a final decision on the type of television that is best for you.

Both LCD and plasma TV's are good and each has certain advantages over the other. However, with the increasing screen size of LCD televisions, comparisons between the two is an important factor in the buying process.

both formats have managed to coexist reasonably amicably, which is mostly due to the problems that LCD's have had with reaching the same sort of screen sizes that plasma television has been able to tackle more or less effortlessly.

The perception among consumers thus far seems to be that LCD is the technology of tomorrow, and plasma is the technology of the past.

With the introduction of larger LCD televisions, some rivalry of technology has arisen between LCD televisions and Plasma televisions. However, when it comes to price, size, and other special features, the public will need to decide which features they really want and how much they are willing to pay for them.that's it .bye.
