Flat panel display facts for kids
Flat panel display is the name for a number of devices which are either used as computer screens, as televisions, or to display information; for example at an airport. Most of them use Liquid Crystal display technology; which is newer than cathode ray tubes.
The most common display technologies are:
- Twisted Nematic (or TN) displays are cheap to produce, but usually they do not have good color rendition. Very often, the viewing angle is limited. Looking at the display from a greater angle changes the colors noticeably.
- In-Plane Switching is a technology that has a very good color rendition, and that does not suffer from the limited field of view. IPS displays are more expensive to produce, and they also show a slower reaction time than TN.
