Summary: LCD-TVs - Part I
The technology I've described in this installment is called TN (twisted-nematic) LCD for obvious reasons. (Confusingly, the liquid-crystal fluid is sometimes called TN as well.) This type of display is inexpensive to manufacture and offers fast response times, so it's often used in computer monitors and laptop screens. However, it suffers from poor viewing angles, so it's not used in modern LCD TVs. Still, it is fundamental to understanding how these TVs actually work, which I'll dig into next time. Until then, happy viewing!
