With all the talk of LCD screens these days, you may find yourself wondering what the name actually means--and more importantly, how these amazing things work. LCD stands for "liquid crystal display." LCD screens represent the combination of some pretty amazing technologies.

Advantages of LCD Screens

LCD screens are filled with liquid crystal, which is basically a type of material that is halfway between a solid and a liquid. Using (believe it or not) a relatively simple process involving electric charges and light polarization, these crystals are manipulated to allow light to pass through with varying degrees of brightness. The result is a video picture that doesn't depend on electrons fired through a large compressed gas tube--as old televisions and monitors do.

LCD screens are great because the nature of the technology allows for enormous screens that don't need to gain in thickness. Where a traditional tube television gets deeper and deeper as the screen size increases, there may be no difference in depth between a 17-inch LCD screen and a 30-inch screen. The fact that LCD screens take up so much less space on your desk or in your living room has been a major factor in their growing popularity.

LCD screens do of course have their disadvantages, but buyers may find that these are far outweighed by the benefits. One of the major annoyances is that picture quality drops off substantially when viewed from an angle. Unless you're watching the screen head-on, the picture tends to fade and become substantially darker.
