A Solid-State Self-Scanning Display Panel

摘要

The solid-state self-scanning display device described in this report consists basically of a piezoelectric ceramic plate which controls the point-by-point excitation of an electroluminescent phosphor layer over the plate. An investigation has been carried out for the optimization of materials and structures employed in the panel. This investigation included the electroluminescent phosphor layer, a nonlinear resistor layer used to obtain high contrast and the piezoelectric ceramic distributor with its input transducer. Techniques for coupling the different planar display components are described. An experimental model of the display panel employing the results of this investigation was constructed. Contract specifications for the model have been met or exceeded. A drive circuit for testing the display panel is described in detail. A recommendation for significantly improving the device is presented. (Author)
