Multilayer electroluminescent display apparatus having multiple,selectively energizable electrode elements forming composite electrodes of predetermined configuration
Abstract
Abstract ELECTROLUMINESCENT DISPLAY DEVICES, SUCH AS THE ALPHANUMERIC TYPE, ARE FORMED WITH A PLURALITY OF ELECTRODE MEMBERS SPEARTED BY A DIELECTRIC MATERIAL ARRANGED IN SUPERPOSED RELATIONSHIP ADJACENT THE SURFACE OF AT LEAST ONE SIDE OF AN ELECTROLUMINESCENT MEMBER WITH EACH ELECTRODE MEMBER COMPRISING A PLURALITY OF DISCRETE ELECTRODE ELEMENTS. THE ELECTRODE ELEMENTS IN THE SEVERAL ELECTRODE MEMBERS ARE CONFIGURED AND RELATIVELY ARRANGED TO FORM SELECTIVE COMPOSITE PATTERNS FROM ONE OR MORE ELECTRODE ELEMENTS SELECTED FROM EACH OF TWO OR MORE ELECTRODE MEMBERS WHICH, WHEN ENERGIZED BY APPLICATION OF AN ELECTRIC POTENTIAL TO THE SELECTED ELECTRODE ELEMENTS, CAUSES AN AREA OF THE ELECTROLUMINESCENT MEMBER TO LUMINESCE IN ACCORDANCE WITH THE SUPERPOSED COMPOSITE ELECTRODE PATTERN.
