Has anyone come face-to-face with an SED monitor yet? I stumbled
across some articles (see below) about SED technology and it sounds
promising. SED was jointly developed by Canon and Toshiba. It seems
like an attempt to combine the best of CRT and LCD technology.
Article #1 - Close Encounters of the Third Kind: SED
http://www.behardware.com/articles/593-1/close-encounters-of-the-third-kind-sed.html
Article #2 (I forget where I found this; hope the author will forgive
my lack of attribution)
"Surface-conduction Electron-emitter Display (SED) monitors are hailed
as the next generation of television screens. Developments in 1986 and
1999 brought about a joint research team from Canon and Toshiba.
Deciding that the venture had a future in the market, they formed SED
Inc. in October 2004.
The biggest selling feature of the SED monitor is its ability to
produce vivid color images that far surpass the types of display on
offer today. With the advent of high-vision broadcasting and broadband
network, along with digital cameras, camcorders and DVDS, demand is
spreading for high quality, high definition displays. Businesses and
the public are seeking larger screens with higher definition and image
quality.
The common television we use today, which mainly uses a cathode ray
tube (CRT), is not suitable to be enlarged beyond a certain point. If
such television sets were enlarged any further than they are now, they
would be significantly heavier and the depth of the units would have
to be deeper. The challenge for manufacturers was to combine a new
kind of display with the same picture quality as the CRT in a slimmer,
larger unit.
The SED monitor has successfully met this challenge. The SED monitor
uses Canon's proprietary electron-emission and microfabrication
technologies. These were combined with Toshiba's CRT and mass
production technologies for Liquid Crystal Displays (LCD) and
semiconductors.
The SED monitor utilises the collision of electrons with a
phosphor-coated screen to produce light, as do CRTs. What makes the
SED monitor unique is the incorporation of a very narrow gap, several
nanometers wide, between two electric poles. When 10 volts of
electricity are applied, electrons are emitted from one side of the
slit. Some of these electrons spread to the other side of the slit,
causing light to radiate when they clash with the phosphor-coated
glass.
As the SED monitor works with the same light production theory as CRT
monitors, it can provide a sharper, more dynamic color than LCDs and
plasma displays. SEDs also have a faster video response time. As the
SED monitor does not require electronic beam deflection, it is
possible to make screens which are only a few centimeters thick.
Another major benefit of the SED monitor is low power consumption. The
SED uses only two thirds of the power needed to run a plasma screen.
It also has lower power consumption than LCDs and the traditional
CRTs. The SED monitor will not only transform the way we view
television and films, but because of its low power use, it will be
earth-friendly too."
