Each pixel is usually composed three sub-pixels, a purple, a inexperienced, and a blue one.

Manufacturers' policies for the appropriate number of defective pixels vary significantly. At one point, Samsung held a zero-tolerance policy for LCD displays sold in Korea. As of 2005, though, Samsung adheres to the much less restrictive ISO commonplace.
