ABSTRACT:
A field emission display with enhanced brightness and contrast, and a method for making such a display, is described. The display has a backplate and an opposing face plate, where a glass plate acts as a base for the faceplate. A patterned layer of transparent conductive material is formed over the glass plate, and acts as an anode for the display. There is a plurality of phosphorescent elements formed over the anode. Openings extending between the phosphorescent elements and through the anode. The baseplate, formed on a substrate, is mounted opposite and parallel to the faceplate. There is a reflective, conductive layer over the substrate. A plurality of electron-emitting tips are formed on the baseplate, extend through openings in the reflective, conductive layer, and are formed directly opposite to the phosphorescent elements, and are divided into smaller groups, or pixels. There is black matrix material over the anode around the periphery of each of the pixels. An anti-reflective layer is optionally formed over the interior surface of the glass plate, or only in the openings. Spacers with a reflective surface may be used, surrounding each pixel, to provide additional reflectivity.
