A comparison of CRT and SED technology
Canon's SED technology could kill off LCD monitors
Canon and Toshiba have teamed up to produce this new flat-screen technology which will be superior to current displays available today. The three main improvements are:
  • Response time - slower response times found on LCD displays can lead to ghosting.
  • Contrast ratio - reported to be 100.000:1, the best LCDs currently only have a contrast ratio of 1000:1.
  • Viewing angle - up to 180, LCD screens can appear dark if they are not viewed straight-on.
SED (Surface-conduction Emission Display) works by using a thin film of Palladium Oxide as an electron emitter which strike a layer of phosphor, just like in a traditional CRT screen. Electrons are emitted at each sub-pixel, and so higher resolution and contrast is achievable. None of the problems associated with LCD screens should affect this technology either because phosphors are illuminated instead of using a backlit display as found in LCDs.

The greater clarity of these new displays will be ideal for photographers and graphic artists, for whom colour accuracy is critical.

Canon hope to be able to market this innovation in the form of televisions by winter 2007. Canon have refused to comment on when this technology will be available for computer monitors, only saying, "There are plans for production, but no details of (SED) monitors can be released at this time."

Looks like a better option than Plasma or LCD... bit of a wait though.

Isn't it funny how eager people get? Just yesterday we've got LCD and Plasma and tomorrow we're crying for SED we don't even know...

cry then... or free yourself from attachment

Two to three decades back any new technology was allowed to mature and would last a decade. The way new technology is being adopted we will not have any one maturing and we would have to abandon it before we can reap the rewards. The consumer is surely the looser since the develpment cost is also paid by the consumer. Those who boought the LCD recently thinking that now is the time as most of the teething problems are sorted are in for a surprise when they find out it is already obsolete.

It's called progress, and leads to economic growth, with a side-effect of wastful obsolescence. Like PCs, if you always waited for the 'best' one, you would never get one, as the next best one is always just around the corner. Electronic goods have generally such a long real lifespan that if everyone stuck to what they had until it broke, and nobody or few bought the new stuff, then the eletronics companies would go out of business.They depend on people buying the new stuff for their income, not only to produce the current goods, but to research and develop the newer goods. And so it goes on, and on..

Nice. But there's other stuff like this in the labs. Every now and then some news leaks as one technology or another achieves some milestone, gets closer to commerciality, or simply gets a journo's interest. Stuff like spindt cathodes. Its all good stuff, who knows which will be the winner(s) and for how long? Personally, I still think OLEP/P-OLED/PLED (the acronym seems to change) is a winner (check out Cambridge Display Technology; its listed in New York under the ticker OLED). And it is already in use in some products - some digicams and some mobile phones; its mainly a question of getting it bigger.
