A Surface-conduction Electron-emitter Display

(SED) is a flat panel display technology that uses

Surface Conduction Electron emitters (SCEs) for

every individual display pixel.

The surface conduction electron emitter electrons

that excite a phosphor coating on the display panel

to display images.

Scans the signal Activates the necessary SCE s, which generate electrons

that fly through the vacuum to the screen

Fabrication of Nano Gaps Nano Gaps are the electron guns of SED Fabricated by hydrogen absorption under high pressure

treatment100nm is normally used as the separation

Scans the signal

However, where CRTs use one

electron gun for the whole

screen, SEDs use an electron

emitter for each pixel

red, green and blue aspect of

simultaneously & virtually

Sharp resolution and fast response(1ms) and only 3cms in thickness

Excellent colour and contrast potential

Relatively inexpensive production cost

180 Viewing angle.

Extremely low power consumption

Lower cost than LCD or PLASMA

overcome

They can be used in a wide range of applications including:

computer monitors,

television, instrument panels,aircraft cockpit displays, signage etc.And in consumer devices such as video players, gaming devices, clocks,

watches,calculators, and telephones with SED Display technology.

Continued development for commercial applications like medical equipment

withSED Display. SED display panel segment is expected to continue displaying growth

additionally, the advent of digital Hi-Vision broadcasting and next-generation DVDs with

best vision quality.

SED monitors can be adopted for military instead ofCRT displays because

they are smaller, lighter and more efficient.
