No argument here. For any and all of the above uses, there really
is no substitute for CRT. Not to mention the narrow viewing angle
and the limited ability of TFT monitors to properly display black.

If there was ever made a monitor based on Smoke-emitting Diodes,
I'd be so getting one. The WTF-factor would be through the roof. =)
Everyone want acronyms for their products these days, so they're
bound to run together. SED in this case is short for Surface-
conduction Electron-emitter Display, which basically is a flat-panel
CRT display, where, rather than sharing one big electron cannon,
every pixel on the display has its own.
No pictures yet, unfortunately.

I had to look this up to be sure I wasn't forgetting something. It
is the current flow itself that causes the crystal layer to twist.
Considering that your typical twisted nematic LCDs have a switching
treshold at around 1.5-2.5 volts, it would be tremendously
susceptible to outside magnetic interference, if a magnetic field
induced between the electrodes would be enough to trigger the switch.
It can be verified relatively simple, by holding a magnet to the
screen. Were LCDs governed by magnetism, there would be a reaction.

As far as offtopic threads go, this one has been pretty docile.
But yes, offtopic no less. Mostly I felt the topic needed to be
clarified a bit, before we sprung a score of ravenous vigilantes,
all but prepared to chew the head off anyone who dared refer to
their flat-panel displays in the same fashion as advertised.

Good reading, thanks.
