There is a bit of confusion for many people when it comes to the differences between LCD and plasma TVs. Many people think that it is the same technology with a different name. They may also believe that a flat screen television or flat screen monitor is the same.
To further that misconception, you can factor in how the LCD and plasma flat screen televisions are different than the typical cathode-ray tv sets still found in many households. If you want to get really confusing, not every flat screen television or flat screen monitor is actually plasma or LCD. Confusing isn’t it?
LCD and plasma TVs vary in how their projection of an image is made. A LCD television is two pieces of a material, transparent of course, that have liquid crystal pumped between. The crystal cells filter the colors.
A plasma TV has two pieces of glass and gas is pumped in between. The gas is charged and the particles, once struck by the gas, give off red, green and blue phosphors. This process produces pixels and makes up the picture.
If one is choosing between lcd and plasma what is the best choice? Opinions vary, but one flaw of plasma televisions is “screen burn”, caused when the set is left on too long. A screen burn occurs when a static image is left on the screen for a long time and remains even when you change the channel.
The burn effect is permanent if a stable image is on the screen for extended perions of time. Computer monitors are also prone to screen burn.
LCD and plasma TVs are probably still considered much better than their predecessors. They are much slimmer and are generally preferred because they take up less space. They can even be hung on walls with the proper mounting equipment and brackets, or you can purchase LCD and plasma tv stands.
Whatever type you choose, compare the pictures and the costs before you make the purchase. If you check around the different retail stores, then you may be able to find a great deal.
