Introduction
SED means “Surface Conduction Electron Emitter Display”, is a flat panel display technology .
Co-developed by Canon and Thoshibacorporation.
A best inter mix of LCD & CRT technologies.
An SED display is very similar to a CRT

Technology
The CRT displays having the signal passing to the screen
The surface conduction electron emitter apparatus consists of a thin slit across which electrons tunnel when exited by moderate voltages

How SED works??
SED has thousand of tiny electron guns known as “emitters” for each phosphor sub-pixel.
A sub-pixel is just one of the three colors (red, green, blue) that that make up a pixel.
It takes three emitters to create one pixel on the screen & over 6 million SED emitters to produce a true high definition image.

Disadvantages
SED may also be susceptible to Screen burn-In.
High production cost.
Un known life expectancy.
Currently prototype only.

Conclusion
SED will be the next generation display technology in the near byfuture,,all of the claims made by the breakers of SED you would
think that there Should be no reason tobuy any other typedisplay
