Question 1

Describe the twisted nematic (TN) technology.

Accepted Answer

The most common TFT displays use a technology called twisted nematic (TN), which produces a decent display for a modest price.Most TN displays use only 6 bits for each color-red, green, and blue-and that 18-bit display will not reproduce the full 24-bit true color that video cards can send to it.This means the panel fudges a little bit when asked to do something it can't do, and this can produce noticeable problems with reproduction.
