We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction electron emitter emits electrons that excite a phosphor coating on the display panel, the same basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs can combine the slim form factor of LCDs with the high contrast ratios, refresh rates and overall better picture quality of CRTs. Canon also claims that SED consumes less power than LCD displays.
In October 2006 Toshiba and Canon demonstrated a television with a 55-inch SED screen at the Ceatac exhibition in Chiba, Japan, saying they plan to put the screens into mass production in 2008.
At 55 inches, the prototype SED screen on display here is the largest yet demonstrated in public
Leading the charge will be these 1080p 55-inch models with 450 nits of brightness, 50,000:1 contrast ratio, stunning 1ms response time...and no price tag yet.
OLED (Organic light emitting diode)
OLED-Displays are the latest and most promising buzzwords in display technology.
To give you an idea of their potential, imagine a cardboard-thin TV screen.
Now imagine that you can roll up your TV, put it away or carry it wherever you go.
Automatically, you start appreciating why millions, if not billions, of dollars are being poured into PLED research every year.
Samsung displayed its 17-inch AMOLED that was only 12mm thick — the panel itself is only 1.8mm thick, at the 2006 Korea Electronics Show. Being one of the thinnest in the world, the display is based on organic LED technology and generates brightness and image quality to LCD displays available today.
