Toshiba / Canon Show Full Functioning Pre Production SED display

Canon and Toshiba's joint venture, SED, Inc displayed pre-production SED (surface emmissive display) technology displays at Canon and Toshiba's CES 2006 booths. 37" model shown are preview of planned 55" 1366 x 786 resolution model release, for Q2 in Japan market.

SED technology is closer to "flattened" CRT technology, but in dimensions and resolutions more like LCD and Plasma.

SED technology, in one form or another has been discussed for the last 5 years, and for 3 years close to reality. Now we are months away from the first commercial launch....lets take a look at whay this technology is so anticipated:

Response time : less than 1 ms!

Contrast ratio : 100,000:1 (brightness is of 400 cd/m²)

Viewing angles : complete, 180° in each direction.

In fact, SED seems to be the offspring of TFT LCD and CRT technologies.

It combines the thinness of the first and the qualities of the second while improving on both!

Like cathode-ray tube TVs, SED technology is based on the collision of electrons with phosphors to emit light; but unlike cathode-ray tubes, there isn’t a single electron gun, but instead a mini electron gun behind each sub-pixel! 1920 x 1080 x 3 = 6.2 million of guns.
