A flat screen cathode ray tube display (10) is self-supporting. A multiplicity of supports extend from an addressing grid structure (35) to contact the inside surface of a face plate (12) between pixels. A back plate (16) is similarly supported against the addressing structure (35). The addressing structure (35) itself is formed of a series of ceramic plates or layers. A matrix of very small holes (44) is formed in each plate. The holes (44), in registry in the laminated addressing grid structure (35), each have adjacent conductive metal traces (54) deposited on the ceramic surfaces, and these traces (54), connected by vias (56, 58) between layers, form a grid of connectors which permit the addressing of each pixel in a sequence in accordance with an input signal such as a video signal. Addressing traces (54) preferably extend between ceramic layers under the hermetic seal of the CRT (10) so that the seal does not directly cross any addressing traces (54). |
