ELECTRON SOURCE COMPRISING EMISSIVE CATHODES WITH MICROTIPS, AND DISPLAY DEVICE WORKING BY CATHOD LUMINESCENCE EXCITED BY FIELD EMISSION USING THIS 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…
