Abstract
An ultraviolet emitter display apparatus and method for making the display is disclosed. The device includes a substrate layer, a pixel electronics layer positioned above the substrate layer, the pixel electronics layer including electronics to drive the ultraviolet emission display. Ultraviolet (UV) emitters may be located above the pixel electronics layer, where the UV emitters may comprise a layer of UV light emitting diodes (LEDs) or a combination of an electron acceleration layer and a UV emission layer. The design further includes a phosphor layer comprising a plurality of phosphor elements, either white phosphor elements in combination with color filters or color phosphor elements.
