HDTV Forum

i know SED is a little ways away, i was just wondering if someone out there would have some intelligent observations about how these two pictures will compare...

A new entry has been added to our dictionary...

Like many things that simply are not out there yet there is not much to say at this point. In all the TIPS List exchanges over CES it was never mentioned once. I will post a link there and see if there is any response.

Richard,

I was at the Toshiba area on a couple of occasions and it didn't catch my eye.

Hugh,

It was there, but behind closed doors.

Richard,

Regarding your question about 1080p, I am writing an article about the
HDTV industry, one section deals with 1080p and includes SED, SXRD and
all the others, and the findings at CES 2005.

SED was demo on a private reception, I do not have time for those if I
have to cover all CES Hi Def properly, I am on the run all the time to
get all the information I need, in fact I made an exception with JVC
on their typical Mandalay Bay set up out of the LVCC.

Regarding SED, other than the explanation of how it works, what I have
for CES is:

CES 2005
SED
SED products are expected to perform with 1 millisecond response time
and 8600:1 CR, and are planned to be offered in late 2005/early 2006
at a price range of LCD-TV panels of equivalent size, starting with
50" model. The company expects SED panels to challenge the flat-panel
market currently dominated by plasmas and LCD-TVs.

36" 1280x720, flat panel with CRT performance (demo)
50" 1920x1080, TTM late 05/early 06, $ TBA

FYI, this is my summarized version of how this SED works:

---------------------------------------------
SED
Toshiba and Canon have been working together since 1999 in a join
venture for the development of SED panels, expected to be 55 inches
and above. Flat panel TV with SED (surface-conduction
electron-emitter display) technology is said to be similar than CRT
beam-emitting technology to obtain comparable clear images but with a
flat panel. SED handles fast images without jagged edges and consumes
one-third the electric current needed by plasma. Although the first
SED televisions could be available in 2005, full production is
expected in 2006.

SED is formed by two glass plates with vacuum in between, one mounted
with electron emitters and pixels similar in number to those of a CRT
electron gun, and another glass plate coated with a fluorescent
substance. The technology has a very narrow slit (several nanometers
wide) made from ultrafine-particle film; reaction to voltage produces
a tunneling effect and the emission of electrons, which are
accelerated by the voltage applied between the glass plates and
collide with the fluorescent-coated glass plate, which emits light.

SED has a wide angle of viewing, similar to CRT. Larger screens can
be manufactured increasing the number of electron emitters to match
the required number of pixels. SEDs do not need electronic-beam
deflection. Wall-mounted large-screen TV displays can be made with
only a few centimeters thick.

Bob,

I have not heard anyone from Toshiba addressing the burn-in subject,
but when you look at how it works, I would suspect that it should be
as the risks of CRT with a bit of plasma mix together; we will find
out soon.
