With all the recent discussions about various display technologies and color
gamuts, I was wondering if anyone has heard anything new about SED displays
and if we¹ll ever actually see one? At least on paper, this really sounds
like an ideal technology that has the best of both CRT and flat-panel
displays and I¹ve really been looking forward to their release, but I¹ve yet
to hear anything about an SED display actually making it into the
marketplace. Also, does anyone know what the expected color gamut for SED
displays will be? I imagine it would be the same type of thing we came to
expect from CRTs...
I wouldn't hold my breath. The announcements a year or so ago along
the lines of "stop buying Plasma and LCD, SED is about to arrive!"
struck me as rather wild for what is an unproved technology. It
had all the ring of investment raising about it, rather than
real product announcements. Technically it just seems like a flat
screen version of the CRT, with all the advantages and disadvantages
that that entails - good blacks, good viewing angle, gamut limited by phosphor,
limited brightness (?), phosphor burn in, etc., and I'd guess there may be some
SED specific issues, such as pixel to pixel uniformity (how uniform
is the electron emitter performance ?), and SED wear out, electronic
driver issues (how do you individually control millions of emitters ?
- you probably don't, you're going to have to multiplex them, giving
a refresh rate), etc.
