ABSTRACT:
The disclosed multi-pixel flat panel displays (e.g., flat panel field emission displays (FPFED) or liquid crystal displays (LCD)) includes spaced apart first and second electrodes, with a patterned solid material layer in contact with one of the electrodes, exemplarily between the two electrodes. The patterned layer (referred to as the "web") includes a multiplicity of apertures, with at least one (preferably three or more) aperture associated with a given pixel. In the aperture is disposed a quantity of a second material, exemplarily, a phosphor in the case of an FPFED, or a color filter material in the case of a LCD. The web can facilitate second material deposition by means of, e.g., screen printing, typically making possible formation of smaller phosphor or filter dots than was possible by prior art device. The web also can facilitate provision of spacer structure between the two electrodes, and can include getter or hygroscopic material.
