FED HDTV
Overview
FED (Field Emission Display) technology
is similar to its cousin: SED. They both produce
images using millions of electron emitters that are located only millimeters
from a phosphorus coated screen. They also both produce images, color and light
when electrons collide with the phosphorus coated screen. The differences
between SED and FED HDTVs is how the electron emitters work.
SED electron emitters use an extremely narrow slit several nanometers wide to help guide the electrons to the correct area of the screen. To get around SED’s patents, FED manufactures are using other methods such as carbon nanotubes to correctly direct the electrons.
Production Update
A Sony spin-off company named Field Emission Technologies plans on producing FED HDTVS no earlier than late 2009. No other manufacture is planning on
producing FED TVs.
