Plasma
How it works:The central element in a fluorescent light is a plasma, a gas made up of free-flowing ions (electrically charged atoms) and electrons (negatively charged particles). Under normal conditions, a gas is mainly made up of uncharged particles. That is, the individual gas atoms include equal numbers of protons (positively charged particles in the atom's nucleus) and electrons. The negatively charged electrons perfectly balance the positively charged protons, so the atom has a net charge of zero.
Plasma TV Screen Advantages: Long life: the average name brand plasma TV will last 50 to 70,000 hours to half life ( brightness is 50% of original, it will still be 2 to 3 times brighter then a regular TV) This is around 20 years at 6 hours per day. Expect substantially less on a no name Field of vision: A plasma screen TV has a field of vision of almost 180 degrees without loss of picture quality. From any angle you will have a great picture
The price for a plasma screenTV is: $279.99
Disadvantages: Plasma televisions had a notorious reputation for conking out after a given set of viewing hours. In 2004, plasma televisions offered a disadvantageous 20,000 hours of viewing pleasure. Compare that to an LCD TV's 50,000 hours. These days, however, plasma televisions have improved and been given longer life spans. Depending on the brand, plasma TVs have a half-life of 60,000 hours. If you're a normal person with a normal family having normal TV viewing hours, that should not be considered a disadvantage. Imagine this: if you spend at least 5 hours in front of your plasma TV, that will translate to about 33 years of use.
