ABSTRACT:
A multi-chromic lateral field emission devices ("FEDs") includes 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.
