Plasma and LCD TV's may look similar but they technology is quite different. With the deadline for networks to broadcast in HD coming up fast it may be time to start seriously thinking of replacing that old cathode ray tube TV. So How do you know which one is right for you and what's the difference anyway? Well, in short a plasma TV is a matrix of tiny gas plasma cells charged with precise electrical voltage to create a picture while an LCD TV is made up of liquid crystals pressed between two glass plates. Images are created by varying the amount of electrical charge applied to the crystals. Each type of TV has it's own advantages and disadvantages and they will be explained below.
Is there a difference in picture quality?
Opinions on this vary depending on who you talk to so the best thing I can suggest is to go down to your local electronics store and take a look for yourself. Just a few years ago plasma TV's did a better job with contrast than LCD's but with the advances in technology this is not always the case. Historically plasma screens had better viewing angles than LCD's. With LCD screens you would see color variations with side viewing while the plasma screen colors remained more constant. This has "mostly" been overcome by LCD manufacturers in the last few years. Make sure you check this visually when looking for a new flat screen. LCD TV's have been known to have problems with fast moving images being blurred. This too has been addressed and for the most part is no longer such a big problem. Be sure look at the refresh rate. The less the number is, the better the quality of fast moving scenes will be. Make sure the refresh rate is under 16ms and you should be fine. Many of the high end models are now at 12ms. LCD TV's can handle a higher native resolution and often can go pixel for pixel so they tend to look much sharper than a Plasma when you are viewing an image that has a high resolution like 1080i/p. Plasma screens are easily scratched so they are protected with a sheet of glass. This adds weight and also can cause glare problems if you are in a room with a lot of windows. When Plasma screens were first produced there life expectancy at full brightness was about 20,000 hours. The LCD screens have always been guaranteed for about 60,000. This problem has been addressed with the newer generation Plasmas and now they are in line with the 50-60,000 hours seen in LCD's
Which one is better for you?
The main advantage a plasma TV has over an LCD is the price of a larger flat panel TV. LCD screens jump quite a bit in price when you start going over 32". If you are on a limited budget and you want a 42 inch screen then the plasma is most likely the one for you. If you have deep pockets and like hi-def and require your image to run at true Native HD resolution then the larger LCD is your best bet.
For the smaller size flat screens 15"-36" the LCD is the way to go. They offer better resolution and if you have noticed the prices keep coming down.
Summary
Plasma's are less expensive for the larger screen sizes and have a slight advantage when it comes to extreme viewing angles. The plasma also wins in handling fast moving images. Both Plasma and LCD now have about the same life span. LCD's are lighter, thinner,and not as fragile as plasma's. When it comes to brightness/contrast many experts favor the plasma but many swear the LCD has similar quality but it really comes down to the make and model.
