SED, I *think* stands for Surface emitter Diode or something. It may have a different name now but it was definitely SED when it was first talked about.
Basically, every pixel is an individual miniature cathode ray emitter, the theory was you'd get the flatness of LCD/plasma but with the superior contrast of a CRT display. I believe it was Sony developing it and they'd got as far as making pre-release prototypes which, if any of them had been up to standard, may have been sold individually (at a very high price) but I think it got shelved when Sony's financial woes caught up with them.
hmmm , interesting , assuming they were fast enough , motion should be very good , and obviously contrast , detail , had never heard of it before ...
