there are many types of televisions like:PLASMA TVLCD TVand many many more...LG Plasma Although they are the darlings of the media and the generic for flat panel display in the minds of many, plasmas are about to be in a serious fight with other technologies for the
flat panel crown.
LCD displays, seen on the desktop for years as computer monitors, and commonplace in smaller flat panel TVs, are finally increasing in size to the point they are becoming a rival to plasmas in the 42" – 50” size range. Picture quality is similar to plasmas; however LCDs are immune to the burn-in that can affect plasma displays. This burn-in occurs when plasma units are used to display static images such as video game screens and stock or sports tickers.
LCD TVLCD TVs are a bit more expensive than plasmas at 42" and larger sizes, but they should last a while longer. Plasma displays should last 20,000 – 25,000 hours and LCDs should give 30,000+ hours of useful life. However, the latest generation of plasma displays from NEC, LG & others is claimed to have a 60,000 hour life. If that is an industry trend, the traditional lifespan advantage held by LCDs may soon disappear. This comes at a time when Sony and other major consumer electronics manufacturers are either abandoning plasma or reducing their plasma offerings. Others, such as Panasonic, Fujitsu and Pioneer are firmly commited to Plasma technology.
Currently Sony has a 42", NEC a 40", Sharp a 45", and Samsung a 40" LCD TV or display.
