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.

While flat-panel TVs have existed in research labs since 1964, they did not become the main display technology until the early 2000s, when the technologies became affordable. They are much thinner and lighter than 1950s-1980s televisions and monitors, which typically used heavy, bulky cathode ray tube (CRT) picture tubes. The flat-panel TV depicted here is from 2008.
