  • Monolithic, milticolor, light emitting diode display device
    Patent number: 3942065
    Abstract: There is disclosed a multicolor monolithic light display comprising a pair of matrices of light emitting diodes in an integral structure which pair of matrices are alternately or simultaneously scannable to produce a red, green or orange display. One matrix includes a plurality of gallium arsenide phosphide (GaAs.sub.X P.sub.1.sub.-X) red light emitting diodes while the other matrix includes gallium phosphide green light emitting diodes. The light emitting diodes are arranged in a geometric pattern of columns and rows with the first matrix interposed with the second matrix so that an alphanumeric character produced by one matrix will appear at almost the same physical location as a character of the alternate color.
