SED Display Guide

HDTV Guides Edition 5 - SED Display Guides

Surface-conduction electron-emitter display (SED) technology Developed by Toshiba - co-developed with Canon.

They say that SED Displays have:

• "same picture quality as a CRT"
• "wall-mounted large-screen TV displays that are only several centimeters thick"
• "energy consumption that is roughly one-half that of a large-screen CRT and about one-third that of a plasma display panel"

Some news broadcasts had stated that the SED Displays would be available at low cost but Toshiba is considering its SED display TVs as their high end HDTV line. They claim the SED displays will have the best resolution and contrast ratio and response time.

There are boasts of very high capability of displaying black with contrast ratio's from 8400:1 to 100,000:1

Like conventional CRTs, SEDs use the collision of electrons with a phosphor-coated screen to emit light. Electron emitters, which correspond to an electron gun in a CRT, are distributed in an amount equal to the number of pixels on the display.
