Sony presented a FED monitor (Field Emission Display) of 19.2 inches, with a resolution of 1 280 X 960, a luminosity of 400 cd/m2 an exceptional contrast rate which reaches 20.000:1! Refresh rate would be between 24 and 240 images per second and the angles of vision would be total (180°), a perfect table.

Field emission display (FED) technology was invented in the 1970s as a possible alternative to the traditional cathode-ray tube TV but has been never commercialized.

What is a SED Monitor?

It’s the next generation of television screens; the SED (Surface-conduction Electron-emitter Display) monitors offer a vivid color images, high definition displays and more larger screens.
The researches began in 1986 by Canon and Toshiba, and later they formed SED Inc. in October 2004.

FED and SED, Two Competitors?

The FED approaches technically the SED, The two Technologies uses hundreds of thousands of micro guns (electron emitters), each one able to generate a pixel, from where the advanced quality of the image With no warm up, heat and No backlight. The FED uses micro guns in cones forms, whereas the SED uses micro guns in the shape of slits, the FED is as finer as the SED, it consumes less energy and it offers a broad angle of vision, and a total absence of dead pixels. Sony aims mainly the professional markets in particular the data-processing monitors (As Computer monitors & televisions) whereas the SED is intended for the market of the large screens.

The marketing of the SED is planned by Toshiba Corp. and Canon for 2009 with Full HD models of more than 26 inches.

THE GREAT LCD MONITOR/ LCD TELEVISION SWINDLE

By russell wyllie, Date: 23/02/2008

I bought the LG 22" 226WTQ-FS Widescreen monitor, with 2ms delay and 60 Hz refresh rate. It is horrible- ugly and blocky at low resolutions, and jitters when watching DVD movies or digital television. LG website advertise it as perfect for movies without blurring or distortion. What a collosal bunch of liars they are!

Your graphics card might be able to produce 100 fps, but LCD monitors only go as high as 75Hz (usually at very low resolution of 960x600 and below). This means you will only see up to 75 frames per second, regardless of the graphics card's ability. My 7950gx2 runs F.E.A.R at 250 fps at peak, and never below 97fps,so a CRT for me is the only option.

Most LCD monitors only use 60Hz (60 frames per second ) in resolutions higher than 960x600, so beware- a CRT monitor is the professional gaming/multimedia monitor you want (Sony 21" Trinitron Monitor with 2048x1680 at 85Hz is great!)

Unfortunately, the market is tied up with LCD's, even though they are far cheaper, they are crap in my opinion, unless you get a 42" LCD television capable of supporting PC's at 100Hz. But there is a snag with the technology in the 42" LCD t.v's- the picture is made stable by adding a black screen in between frames, so you get a consistant brain-fooling, where you think you've seen a smooth picture, but in fact whatever you see will be a series of picture-black-picture-black-picture (60 frames of picture and 40 frames of black screen), not like the CRT's smooth 100 fps of picture. LCD colours are also often less accurate than a CRT. Other LCD displays use a 3:2 rendering method to increase line drawn on the screen (making 3 images out of two).New SED monitors and televisions are in production in China, which are sited as better than LCD, more reliable than a Plasma and less bulky than a CRT. Hang on to your CRT until the SED screens appear in shops.

Or, get a Sony or Viewsonic widescreen CRT at 21", and be grateful that I let you know what a swindle the LCD industry really is...
CRT's are becoming obsolete, so you may not find a widescreen very easily- but it's worth shopping for one...

LCDs are Junk

LCDs Inferior technology for high profit margins that give you motion sickness and eyestrain.
SED is teh Beta Max of the computer monitor industry
it's better then VHS but only if people stop buying LCDs!

SEDs will be expensive

By Franco, Date: 03/09/2008

Although the SED technology is cheaper to produce, the costs will remain high until the stocks of the LCDs, Plasmas and anything else that hasn't sold is sold. Another ripoff by the manufacturers. SEDs were susposed to come onto the market at 50" to 110" displays. Now Canon-Toshiba will make smaller versions to make up the costs of initial production and the law suits that held up SED production. You can look for a low end monitor to be quickly replaced by a higher end and on and on until they produce the SED they planned on for several years ago. Its no longer about new technology, its all about money and profits...real big profits. If we stopped buying LCDs and Plasmas for 90 days, the prices would drop. They are still producing cheap LCDs that do not live up to the hype. I'll keep my CRT until the SEDs are up to the standards I need and not what they think I need.

Where can I view an FED/SED in the UK.
I also dislike the LCD but could not wait for SED/FED to appear!
When FED/SED appear at the right price in the UK ( similar to LCD/Plasma)I will buy one.
