All About Those Big TV Screens
The new LCD televisions which are huge and crystal clear use the same technology featured in laptop computer screens and flat-panel desktop monitors. Compact, lightweight, and sharp, LCD TVs provide a sleek and visually superior or alternative to traditional TVs, which use cathode ray tubes. This type of technology is big in scope. This type of plasma display uses technology found in larger flat-panel screens, which typically start at 36 inches across diagonally.
Mainstream LCD TVs have experienced a serious growth spurt in the past few months, expanding from a maximum size of 20 inches to more than 30 inches. Plasma screens, which use a different display technology, have dropped drastically in price making them more affordable for everybody. A 42-inch plasma model that cost seven grand three years ago can now be had for three grand.
You might be wondering whether or not you should buy a plasma or LCD screen. Plasma screens initially seem to be the better deal because they offer the best bang for the buck on the showroom floor. Today, three grand will get you either a 30-inch LCD or a much larger 42-inch plasma TV. However you should also be aware that these televisions emit a lot of heat, are expensive and can be noisy. The plasma has better images but it a much clunkier and awkward set.
The difference between LCD and Plasma technologies is simple. LCD screens employ millions of individual crystals, each of which responds to an electric charge to allow a specific amount and color of light to pass through the glass. Plasma screens use millions of tiny glass bubbles filled with a gas-like substance called plasma. When exposed to an electric charge, the plasma emits ultraviolet rays that cause the coating on the glass to wear out. So in theory the LCD TV is a better buy because it won’t degrade as fast. It also does not have a noisy fan in the back like Plasma.
On the other hand the Plasma image can be better. The pixels on LCD televisions can have slow response times. The colors can also be off on the LCD and it is hard to see the television from an extreme angle.
LCD screens are immune to screen burn in and fade, which means they offer a significantly longer useful life than their plasma counterparts. Another advantage: LCD panels consume about half the power and produce much less heat than plasma displays so they are more economical.
