New article on Field Emission tv developments

Have a look at:
http://technology.guardian.co.uk/wee...813113,00.html

"A 20-inch prototype display is expected by the end of next year and, beyond that, 32-inch or even 42-inch sizes beckon, with production pencilled in for 2009 or 2010".

It's a long time to wait... personally, I can just about hold out for the Toshiba/Canon SED (but if they delay it again, there's gonna be a 50in 1080p Pioneer plasma with my name on it).

Goodness me, now we have polymer light-emitting diode (PLED) tv technology to deal with as well. And I thought the current tv market was confusing enough!

I'm just hoping for something thats as good with HD as an LCD and handles SD as well as an old CRT.

I can hope can't I!

cant they just make an LED tv? as in every pixel is made out of 3 leds RG&B? imagine the black levels lol cant get blacker than off!
colour reproduction might be a bit pants tho

Yes, it's OLED. All the LCD guys are working on it. The early ones look really good, BUT (and it's a big but) the lifetime especially of blue is very poor (1500 hrs or so). In addition there is a problem in that the materials are degraded by moisture. Solving the encapsulation so that humidity in the air doesn't eat the display is a huge hurdle.

Dream on until after 2010. But the potential for the technology is fantastic. Remember that LCDs will have had another 5 years of development too however, and much of what we discuss at present about motion etc will have been solved.

oled isnt the same as led, im talking about the leds that you solder onto a circuit board lol, imagine the head generated from the thing!

Bearing in mind the pixel size you'd need a 400" display - but they already exist for public displays. There's a big one outside Amsterdam Airport.

As LED uses silicon, the only solution would be to tile wafers..and at $50k for a 12" wafer not exactly a consumer product...

As SED is still fixed resolution it's more than likely it won't be much better at all for SD material. The TV would have to have a good scaler and de-interlacer to do that, and that certainly won't be as good as 480i or 480p done natively on a CRT. Considering you need a scaller costing around £800 to achieve excellent results.

It would be better for them just to produce a multi-sync CRT without any slim designs. At around 26" 28" although expensive is easily possible to produce good geometry, colour, brightness and contrast levels.

SED cannot scan like a CRT so it cannot adjust it's resolution, meaning panels although going to be CRT quality for naitve res stuff, anything else won't look all that great.
