What’s an SED monitor?

SED monitors are the next generation of TV screens, offering vivid color images and high-definition displays. They use electron emission and micro-manufacturing technologies to produce light, with a narrow gap between two electrical poles. SEDs provide sharper color and faster video response time than LCDs and plasma displays, while also having lower power consumption.

Surface conductive SED (Electron-Emitter Display) monitors are being hailed as the next generation of television screens. Developments in 1986 and 1999 led to a joint research team from Canon and Toshiba. Deciding that the firm had a future in the market, they formed SED Inc. in October 2004.

The best-selling feature of the SED monitor is its ability to produce vivid color images that far exceed the types of displays offered today. With the advent of high-vision broadcasting and broadband networking, along with digital cameras, camcorders, and DVDs, there is a growing demand for high-quality, high-definition displays. Businesses and the public are looking for bigger screens with higher definition and picture quality.

The common television we use today, which primarily uses a cathode ray tube (CRT), does not lend itself to being enlarged beyond a certain point. Were such TVs enlarged further than they are now, they would be significantly heavier and the depth of the drives would have to be greater. The challenge for manufacturers was to combine a new type of display with the same image quality as a CRT in a thinner, larger unit.

The SED monitor has successfully met this challenge. This monitor uses Canon’s proprietary electron emission and micro-manufacturing technologies. These were combined with Toshiba’s CRT and mass production technologies for liquid crystal displays (LCDs) and semiconductors.

The SED monitor uses the collision of electrons with a phosphor-coated screen to produce light, as do CRTs. What makes this monitor unique is the incorporation of a very narrow gap, several nanometers wide, between two electrical poles. When 10 volts of electricity is applied, electrons are emitted from one side of the slit. Some of these electrons scatter to the other side of the slit, causing light to radiate as they collide with the phosphor-coated glass.

Since the SED monitor works on the same light production theory as CRT monitors, it can provide sharper and more dynamic color than LCDs and plasma displays. SEDs also have a faster video response time. Since the monitor does not require electronic beam deflection, it is possible to make screens a few centimeters thick.
Another important advantage of the SED monitor is low power consumption. The SED uses only two-thirds of the power required to operate a plasma screen. It also has lower power consumption than LCDs and traditional CRTs. Not only will this monitor transform the way we watch television and movies, but thanks to its low power consumption it will also be environmentally friendly.
