Abstract
A flat panel display including a plurality of electrically addressable pixels; using a passive matrix on a first substrate, a passivating layer on at least partially around the pixels; a conductive frame on the passivating layer, and a plurality of cold cathode emitters on select portions of the conductive frame within the display, wherein exciting the conductive frame and addressing one of the pixels using the associated passive matrix causes electrons to strike at least one of the pixels and result in the emission of light from those pixels. Using a metal layer (ML) on a second substrate the extent of electrons emitted is enhanced through the incorporation of a noble gas or mixture thereof, causing a multiplication of the electrons emitted by the cold cathode when the gas is ionized.
