SEDs Find Backing for Research.
Canon and Toshiba will jointly develop a next generation large screen surface conduction electron emitter display (SED). This new display technology is similar to the CRT in that light is emitted when an electron beam hits a fluorescent body. But instead of a single electron beam position on the screen being controlled by a single electron gun, each of the SED pixels has a miniature electron- emitting counterpart. The difference between SEDs and field emission displays (FEDs) is in the structure of the electron-emitting component.
In an SED, two electrodes are placed near each other on a surface. They are coated with a film of oxidized palladium particles with a nanometer gap in the middle. A voltage is applied across the electrodes and electricity is ...
