Abstract: A method for creating a faceplate of a display provides a faceplate substrate with a faceplate interior side and a faceplate exterior side. A plurality of barriers are formed on the faceplate interior side, with the barriers defining a plurality of subpixel volumes. Phosphor containing photopolymerizable material mixtures of red, green and blue, are deposited into subpixel volumes, and create a faceplate interior side/phosphor interface. At least a portion of the phosphor containing photopolymerizable material mixture is exposed with sufficient actinic light through the faceplate interior side/phosphor interface to polymerize a selected depth of the phosphor containing photopolymerizable material mixture in the subpixel volumes, and form a polymerized phosphor containing material in a plurality of subpixel volumes. Non-polymerized phosphor containing photopolymerizable material is removed from the polymerized phosphor containing material.

Abstract: A method for forming a three-dimensional multi-level conductive matrix structure for a flat panel display device. In one embodiment, the present invention forms first pixel separating structures across a surface of a faceplate of a flat panel display. The first pixel separating structures separate adjacent first sub-pixel regions. In this embodiment, the first pixel separating structures are formed by applying a first layer of photo-imagable material across the surface of the faceplate. Next, portions of the first layer of photo-imagable material are removed to leave regions of the first layer of photo-imagable material covering respective first sub-pixel regions. Then, a first layer of conductive material is applied over the surface of the faceplate such that the first layer conductive material is disposed between the aforementioned regions of the first layer of photo-imagable material. The present invention then removes the regions of the first layer of photo-imagable material leaving only first pixel separating structures formed of the first layer of conductive material, disposed between the first sub-pixel regions. The present invention performs similar steps in order to form second pixel separating structures between the second sub-pixel regions. The second pixel separating structures are formed substantially orthogonally oriented with respect to the first pixel separating structures and, in the present embodiment, have a different height than the first pixel separating structures. In so doing, a three-dimensional multi-level conductive matrix structure is formed.

Abstract: A multi-level conductive matrix structure for separating rows (106, 108) and columns (110-122) of sub-pixels on a faceplate (104) of a flat panel display device is disclosed. The matrix structure has a first plurality of parallel spaced apart conductive ridges having a height, a second plurality of parallel spaced apart conductive ridges having a height higher than the height of the first plurality of conductive ridges, and the height of second conductive ridges decreases to the height of first conductive ridges at intersections of the first and second conductive ridges.

Abstract: On a flat panel display structure, having a raised black matrix (200) defining wells within the matrix, is deposited a non-conformal, planar layer of acrylic-containing aluminizing lacquer (208) over a layer of phosphors (206) residing within the wells of the black matrix. A planar layer of catalyst material (210) is deposited over the layer of lacquer (208). A planar aluminum layer (212) is subsequently deposited over the catalytic layer (210). Finally, a baking process is conducted at a temperature such that the lacquer layer (208) and the catalyst layer (210) are cleanly and completely evaporated. This temperature is relatively low so as not to adversely affect the reflectivity of the aluminum layer (212), damage the black matrix material (200), or induce oxidation of phosphors. A substantially planar and mirror-like aluminum surface is achieved.

Abstract: A method for forming a conductively coated matrix structure for separating rows and columns of sub-pixels (106) on the faceplate (104) of a flat panel display device. One embodiment deposits a photoresistive material (108) over the interior surface (102) of a faceplate having a non-conductive opaque matrix structure (100) formed thereon, and into sub-pixel regions separated by the matrix structure. The photoresistive material is dried and exposed to light (112) in the sub-pixel regions. After unexposed photoresistive material (110) is removed, a layer of aluminum is evaporated onto the interior surface of the faceplate such that the matrix structure and the exposed layer of photoresistive material in the sub-pixel regions is coated with conductive aluminum. Next, an etchant is applied to the exposed photoresistive material disposed in the sub-pixel regions, removing the exposed photoresistive material and the overlying Al layer from the sub-pixel regions, such that the conductive Al layer remains only on the matrix structure, and does not cover the sub-pixel regions.

Abstract: A method for creating a color filter on a display screen that allows better and more efficient adhesion of color pigment crystals to the screen display structure. In one embodiment, the present invention creates a color filter on a glass substrate having a pixel-defining structure. The present embodiment first creates a color filter slurry by mixing a polyvinyl alcohol solution with a color crystal pigment. The color filter slurry is then applied onto the interior surface of the display screen. The slurry is then dried. The dried color filter slurry is then exposed to an UV light from the exterior side of the display screen. The UV light exposes the color filter slurry through a photomask and through the display screen. The excess layer of color filter slurry is then removed, leaving behind a color filter of desired transmission wavelength such that light having similar wavelength are substantially transmitted and light of wavelengths different from said color pigment crystals are substantially filtered out by absorption.
