Sony demonstrated the current state of their FED (Field Emission Display) TV display technology in Japan.
Sony introduced a 19.2 inch FED panel. The specifications of this FED display are quite interesting with 1,280×960px resolution, a brightness of 400cd/m2, a contrast of 20,000: 1 and 0.306mm pixel pitch. The FED display technology uses the same principles as CRT and is supposed to have better picture quality than LCD and Plasma panels and has low power consumption.
FED is not SED, but also not that different. First FED panel TVs are earliest to be expected in 2009.
Sony handles FED development via a company called Field Emission Technologies Inc., which they formed back in 2006 TechGate Investment Inc.,.
