ABSTRACT:
Multi-chromic lateral field emission devices ("FEDs") and methods of fabrication are set forth. The multi-chromic FEDs include a phosphor layer disposed substantially perpendicular to an emission surface. Associated with the phosphor layer are multiple emission regions, and associated with each emission region is an emitter and a filter. Operationally, when electrons are transferred from an emitter into the phosphor layer, a light emission is produced from the associated emission region. The associated filter selectively passes desired wavelengths of light. Specific details of the field emission device, an associated display, and fabrication methods are set forth.
