TRIODE STRUCTURE FLAT PANEL DISPLAY EMPLOYING FLAT FIELD EMISSION CATHODES

摘要

A flat panel display for displaying visual information includes a plurality of corresponding light-emitting anodes (130), and fieldemission cathodes (170), each of the anodes emitting light in response to emission from each of the corresponding cathodes, each of the cathodes (170) including a layer of low work function material having a relatively flat emission surface of a plurality of distributed localized electron emission sites and a grid assembly (102) interposed between the corresponding anodes (130) and cathodes (170) to thereby control emission levels to the anodes from the corresponding cathodes.
