LCD TV – The Good and the Bad
An LCD TV is very thin and light and therefore great to save space. Anyone who has an LCD monitor for their desktop computer will relate. Remember the large chunky one ones we used to all have? That is what a standard television set is like now. Along with great picture quality there is almost not static image burn-in problems because the fluorescent backlight is filtered by the liquid crystal in solid state.
The TV lasts a life time or for as long as 50,000 to 80,000 hours claimed by manufacturers. This outshines the plasma whose life expectancy is much less. These TVs will last as long as the backlight can produce white light. The backlight can be changed out too so they are extremely good value in that regard. It can also be doubled up for use with a computer of any kind. Most computers monitors are LCD anyway.
LCD’s are economical meaning they are good for the environment. LCD TVs use less power than Plasma TV’s or CRT TV’s and in some cases less than half the power!
They are not currently available in the larger sizes greater than 40in. When made in larger sizes, they are more expensive than plasmas.
The use of filters and a white backlight can reduce the quality of a true red green and blue output. Blacks look more like dark grays because some of the white light always passes through.
There is a possibility for reduced angle of vision. As the white light passes directly through an LCD pixel and the nature of polarizing filters, the viewing angle is decreased. You will notice loss of quality for blacks and colors at angles greater 20 degrees off axis.
To be fair I think the good outweighs the bad and they are extremely good value for money compared to the plasmas unless of course you want a really big screen.
