«~» From Canon and Toshiba : How Does all this 'SED Stuff Work ?'

«~» Well, instead of having one big electron gun, as we do in a typical CRT television, shooting out
a stream of electrons that zap the phosphors on a TV screen causing them to emit light, in SED
technology, each pixel has 3 of its own microscopic electron emitters, each lighting up the red,
green and blue phosphors within the individual pixel. In a SED TV with a resolution of 1920 x 1080
pixels, the resolution the first SED displays are expected to appear at, that will be a total of
6,220,800 emitters. The electron emitters, a thin film of Palladium Oxide, can be positioned just
millimeters from the phosphor-coated pixels resulting in the slim form factor ;

«~» That's it, in a nutshell, pretty easy to visualize, a lot harder to implement ;

«~» Some key specifications for the 1080p models : 50,000:1 contrast ratio, 1ms response time,
450 nits brightness, 30,000 screen life and low power consumption in comparison to Plasma and
LCD screens ;

«~» When the anticipated full scale production of 70,000 units a month hits its stride towards the
end of 2007, SED televisions should incorporate the picture quality, sharp resolution and fast
response times of traditional CRT tube TVs with the size, weight and form factor of Plasma and
LCD displays, while all the time keeping power consumption extremely low.
