Monolithic light indicator with a matrix array of light-emitting semiconductor diodes

摘要

There is disclosed a monolithic light display comprising a matrix of light emitting diodes in an integral structure which is scannable to produce an alpha numeric character display. Groups of the light emitting diodes are electrically isolated from other groups of diodes by a supporting carrier and an isolation channel with the cathode of the diodes connected in a series of groups by address or row lines and anodes connected in an orthagonal plurality of groups by bit or column lines. A conductive bus in the isolation channel forms the connection for either the row or column lines. A strobing format logic address system is provided for lighting the individual diodes to emission for producing an alpha numeric character.
