SURFACE CONDUCTION ELECTRON EMISSION DISPLAY(SED)
Introduction
STRUCTURE OF SED
Three main parts
The Glass panel and Phosphorous layer
The Surface conduction electron emitting unit
The Spacer
Fig-1 INTERNAL STRUCTURE OF SED
FABRICATION PROCEDURE
Nano gaps are the electron guns of SED
Fabricated by hydrogen absorption under high pressure treatment
Edge roughness of nano gaps improves electron emission
100nm is normally used as the separation
The thicknesses of this device are shown in the bottom-right corner
Working of SED
Creating the picture
It’s a electron emitting device
Electrons are emitted from the electron emission region by applying a voltage to the electrodes
A set has three SCE’s for every pixel
Millions of these SCE’s are arranged in a matri
