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.
