Electron source with micropoint emissive cathodes and display means by cathodoluminescence excited by field emission using said source

摘要

Each cathode (5) comprises an electrically conducting layer (22) and microtips (12) and, according to the invention, a continuous resistive layer (24) is provided between the conducting layer and the microtips. The display device comprises a cathodoluminescent anode (16) opposite the source. …IMAGE…
