ABSTRACT:
An emissive display comprising: a first substrate including a plurality of controllable anodes; a layer of phosphor on each of the controllable anodes, wherein each phosphor emits light when the anode on which the phosphor is located is activated and electrons bombard the phosphor; a second substrate comprising a light transmissive lens having a display area through which a display is viewed, first and second electrically conductive layers and an insulating layer, wherein the first and second electrically conductive layers and the insulating layer are light transmissive, wherein the insulating layer is between the first and second electrically conductive layers and wherein the first and second electrically conductive layers and the insulating layer are on a side of the lens facing the controllable anodes and phosphor layers, wherein the second electrically conductive layer is located closer to the first substrate than the first electrically conductive layer and comprises a first plurality of holes corresponding to a second plurality of holes in the insulating layer; a plurality of opaque field emitter cones mounted to the first electrically conductive layer in the first and second plurality of holes, emitting electrons to selectively bombard the phosphors layers, wherein the plurality of opaque field emitter cones covers less than ten percent of the display area of the second substrate, wherein the emitted electrons travel through a space between the second electrically conductive layer and the phosphor layer, wherein light emitted from the phosphor layer travels back through said space and through the second substrate to be viewed by a viewer of the display.
