1. A flat panel display comprising in combination:

  • a substrate;

    an opaque insulating dielectric deposited on a portion of said substrate including;

    a plurality of coupling window means for permitting the transmission of light therethrough; and

    a plurality of decoupling window means for permitting the transmission of light therethrough, said coupling and decoupling windows being arranged in side-by-side columns and offset from one another;

    ground conductor having a substantially rectangular area and a longitudinal axis parallel to said columns of coupling and decoupling windows, and further having rectangular extensions therefrom having a longitudinal axis substantially perpendicular to the longitudinal axis of said first portion, said ground conductor being deposited upon said substrate and said extensions being deposited to intersect with said decoupling windows, insulating dielectric deposited over said rectangular area of said ground conductor;

    first conductive means being substantially rectangular in form and having a longitudinal axis parallel to said columns of said coupling windows and further being deposited to intersect with said coupling windows;

    a plurality of conductive grids having an axis substantially perpendicular to said coupling and decoupling window means and deposited over said insulating dielectric and said opaque insulating dielectric such that said plurality of conducting grids intersect with said decoupling and said corresponding coupling windows; and

    photoconductive material deposited over said conductive grids and said rectangular extensions of said ground electrode in the area of said opaque dielectric insulator to form, in conjunction with said plurality of coupling window means and decoupling window means, a plurality of voltage dividers.
