<p>In accordance with the present invention, shown in the figure, a method of electrophotographically manufacturing a phosphor screen, comprises the steps of coating (44) an interior surface of a viewing faceplate panel to form a volatilizable organic conductive (OC) layer and overcoating (46) the OC layer to form a volatizable organic photoconductive (OPC) layer. The OPC layer is electrostatically charged (48) and selected areas of the OPC layer are exposed to light to form a charge image (50). The charge image is developed with at least one phosphor material (52) which is fixed (58) to the OPC layer by spraying a fixing solution comprising two solvents, having substantially different rates of evaporation onto the phosphor material on the OPC layer to affect the solubility thereof and to make the OPC layer tacky. At least a portion or all of the solvent with the higher rate of evaporation is allowed to evaporate while the solvent with the lower rate of evaporation retains the tackiness of the OPC layer. The phosphor material on the OPC layer is resprayed with the fixing solution comprising the two solvents having the substantially different rates of evaporation to uniformly fix the phosphor material to said OPC layer. Then, the fixed phosphor material is filmed (62) and an aluminum layer is deposited thereon (66) to form the screen assembly which is baked at an elevated temperature to drive off the volatilizable constituents thereof.</p> |
