Patent US 4,112,466

A television screen comprising an electroluminescent sheet sandwiched with electroconductive sheets. Electrical pulse signals responsive to a horizontal sweep input are applied to the sides of two of the electroconductive sheets, and pulse signals responsive to a vertical sweep input are applied to the top and bottom of two of the electroconductive sheets. The pulses are modulated with the video input. The signals propagating across the sheets produce a dot at the intersection point, which moves in accordance with the pattern of the sweep signals to produce a video picture.
