SED, or Surface Conduction Electron Emitter Display, is a flat panel display technology co-developed by Canon and Toshiba that combines aspects of LCD and CRT displays. SED has thousands of tiny electron guns called "emitters" for each color sub-pixel that emit electrons to illuminate phosphors when excited by moderate voltages, similar to a CRT, but without the deep vacuum required. Potential advantages of SED include fast response times, high brightness, excellent color and contrast, wide viewing angles, and low power consumption, but high production costs and potential for screen burn-in remain challenges.
3. Introduction
SED means “Surface Conduction Electron Emitter
Display”, is a flat panel display technology .
Co-developed by Canon and Thoshiba
corporation.
A best inter mix of LCD & CRT technologies.
An SED display is very similar to a CRT
4. 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
5. How SED works??
SED has thousand of tiny electron guns known a
“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
true high definition image.
10. Conclusion
D will be the next generation display technology in the n
ure,,all of the claims made by the breakers of SED you w
nk that there Should be no reason tobuy any other type
play
