ABSTRACT:
A field emission display (200) includes a cathode plate (202); a substrate (102) opposing the cathode plate (202); a conductive matrix (104) disposed on the substrate (102) and having via walls (103) defining a plurality of phosphor vias (105); a phosphor (106, 108, 110) disposed within each of the phosphor vias (105); and a gas-adsorption material distributed within the conductive matrix (104). A method for fabricating the field emission display (200) includes the steps of silk-screening onto the substrate (102) a screenable suspension, which is made from a glass, a metal, a gas-adsorption material, and a photo-sensitive material, to form a film; photo-patterning the film to form a phosphor via (105); depositing a phosphor material into the phosphor via (105) to form an anode plate (100); and affixing the cathode plate (202) to the anode plate (100).
