Canon & Toshiba demo SED TV @CES, yet another HD disp tech
Despite all the display technologies that have been come up with, such as Plasma, LCD, Rear projection, OLED as well as projectors, most still have a hard time trying to match the picture quality of a good CRT display. Unfortunately, large CRT’s have a major drawback due to their depth, never mind the sheer weight! As most consumers only have a standard definition TV, they will need to upgrade to a HDTV set in order to get the benefit out of high definition content, particularly with the expected launch of Blu-ray and HD DVD players & movies over the coming months as well as the increasing number of HD broadcasts becoming available.
Well, Canon and Toshiba have been demonstrating a yet another display technology, this time SED (Surface conduction Electron-emitter Display). This works in pretty much the same way as a CRT TV, but with the exception that each phosphor has its own dedicated electron emitter, unlike a traditional CRT which has one main electron gun. As a result, these electron emitters can be placed in close proximity to their designated phosphors, resulting in a very thin display, but with all the advantages of a traditional CRT display, such as deep blacks, 1ms response and a contrast ratio of up to at least 100,000:1, but without the weight and depth of a regular CRT TV.
The only drawback the display has is that as its resolution is fixed to the number of phosphors, the TV only works best at its native resolution, as with plasma, LCD and other fixed resolution displays. According to the source, the TVs demonstrated at the CES had a size of ~30″, although it is unclear what its native resolution is.
