Plasma uses gas plasma cells charged by precise electrical voltages to create a picture.



LCD screens (liquid crystal display) are in layman's terms sandwiches made up of liquid crystal pushed in the space between two glass plates. Images are created by varying the amount of electrical charge applied to the crystals



Each technology have their pro & cons, here are pros & cons for your decision

Pros of Plasma

- Better contrast ratio

- better ability to render deep blacks, more color depth,

- better motion tracking (response time)

- more availability in very large screen sizes.



Cons of Plasma

- more susceptible to burn-in (although this is not as much of a factor now, due to technology improvements in the past few years)

- more heat generation (as well as more power consumption)

- screen glare in brightly lit rooms

- heavier weight, and more delicate to ship.



Pros of LCD

- LCD television advantages include no burn-in susceptibility

- cooler running

- less screen glare, more functional at high altitudes

- longer display life (although improvements are being made in Plasma screen life)

- looks better in brightly lit rooms

- less power consumption than Plasma.

Cons of LCD

- Lower contrast ratio

- not as good rendering deep blacks

- not as good at tracking motion (although this is improving, especially with the implementation of 120Hz refresh rates (and some now offer 240Hz) on higher-end models).

I recommend that you go online to Home Theater Magazine and read the reviews on tvs, along with the pro and con of each technology. You will notice that Panasonic has more plasma tv being recommended than any type of tv from any manufacturer. In November issue of the magazine it named the Panasonic plasma tv model VT25 as the best tv for 2010. If you read yahoo questions, you will notice that 95% of tv problems comes from LCD tv and 95% of those are the bargain price tv. Hope this will help you out.

plasma eat power up the watts a good LCD can save you a lot of money make sure you look at the box of the LCD TV to make sure it a ECO TV and Enegy star TV to!

Outward appearances are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results.



Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element).



LCD TVs, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer.



The ADVANTAGES of Plasma over LCD are:



1. Larger screen size availability.



2. Better contrast ratio and ability to render deeper blacks.



3. Better color accuracy and saturation.



4. Better motion tracking (little or no motion lag in fast moving images).



The DISADVANTAGES of Plasma vs LCD include:



1. Plasma TVs are more susceptible to burn-in of static images. However, this problem has diminished greatly in recent years as a result of the incorporation "pixel orbiting" and related technologies.



2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images.



3. Does not perform as well at higher altitudes.



4. Potentially shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements.



LCD television ADVANTAGES over Plasma include:



1. No burn-in of static images.



2. Cooler running temperature.



3. No high altitude use issues.



4. Increased image brightness over Plasma, which makes LCD TVs better for viewing in brightly lit rooms.



5. Lighter weight (when comparing same screen sizes) than Plasma counterparts.



6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans.



DISADVANTAGES of LCD vs Plasma televisions include:



1. Lower contrast ratio, not as good rendering deep blacks, although the increasing incorporation of LED backlighting has narrowed this gap.



2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving with the recent implementation of 120Hz screen refresh rates and 240Hz processing in higher-end LCD sets.



3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with 46 and 47-inch screen sizes becoming more common, and some LCD sets having a screen size as large as 65-inches also available to the general public.



4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you.



5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing).

The final decision as to what type of flat panel television to purchase (LCD or Plasma) is really up to you here are pros & cons of each for your decision these pros and cons may help to you deside which one is more better



Pros of Plasma

- Better contrast ratio

- better ability to render deep blacks, more color depth,

- better motion tracking (response time)

- more availability in very large screen sizes.

Cons of Plasma

- more susceptible to burn-in (although this is not as much of a factor now, due to technology improvements in the past few years)

- more heat generation (as well as more power consumption)

- screen glare in brightly lit rooms

- heavier weight, and more delicate to ship.

Good brand that I would recommend for Plasma is Panasonic or Samsung
