field-emission display

field-emission display

[′fēld i‚mish·ən di‚splā]
(electronics)
A flat-panel electronic display in which electrons are extracted from an array of cold-cathode emitters by applying a voltage between the cathode and a control electrode, and the electrons are then accelerated without deflection over a distance of less than 1 millimeter before colliding with a phosphor-coated flat faceplate.

Satisfying field-emission display requirements, it can produce an array of 0.2 [[micro]meter] to 0.5 [[micro]meter] emitters over an area of about 2,600 [cm.sup.2], with better than 5% height and spacing uniformity.
Displays referred to as field-emission displays (FED) operate on the principle of electrons bumping up against fluorescent bodies, and causing them to emit light.
The company says that its technology will allow largearea flat-panel displays to be produced at lower cost than plasma-display panels or other field-emission displays. PFE's technology is based on thin-film glassy insulators with embedded conducting sites that allow the emission of electrons at low electrical-field strengths.
