SED is a very interesting technology which should start making its 
mark in a couple of years.  It uses CRT phosphors to produce CRT-like 
behavior but without the light-scatter problems of a CRT tube.

As usual the 100,000:1 contrast ratio is way overstated.  It is based 
on SED being able to obtain true black because the electron emitters 
can be turned completely off.  It remains to be seen how well 
real-world SED displays will handle the region near black.

If SED was indeed able to produce a userful contrast range of 
100,000:1, then surely far more than the current 8-bits would be 
necessary to control it.
