AnandTech: LCD Tips, FAQ, & Glossary
(Click here to view the original thread with full colors/images)
Posted by: TotalRecall
Looking for a new LCD monitor, or just have some general questions? AnandTech has written a short guide to LCDs, with some FAQs, tips, and a glossary of commonly used terms.
To briefly go over how LCDs are possible, we have to understand Reinitzer’s discovery 115 years ago. Cholesteryl benzoate is a very tightly packed fibrous material. Typically, it arranges itself in a tight helix pattern that is “twisted” together. Although LCDs today don’t use cholesteryl benzoate, the materials used today share some similar properties. Modern LCDs are composed of a pool of twisted liquid crystals in front of every sub-pixel on the display. Applying various degrees of current to the liquid crystals untwists them ever slightly (enough to allow light to pass).
This very important principal in LCD technology is called the twisted nematic field effect. The important thing to understand is that LCDs do not generate light; they simply allow or inhibit light from passing through a certain place on a substrate.
Check it out here. While you're there, they also have a preview up on the Athlon 64. They've taken an 1.8GHz Opteron and nForce 3 reference board and overclocked to 2 GHz, the expected speed of the Althon 64. Read on here.
