Color display system

Claim 1

A COLOR DISPLAY SYSTEM COMPRISING: A KINESCOPE INCLUDING, AN ENVELOPE OF DIELECTRIC MATERIAL, SAID ENVELOPE HAVING A FACE PORTION, A NECK PORTION AND AN INTERMEDIATE PORTION CONNECTING SAID NECK PORTION TO SAID FACE PORTION, A PHOSPHOR SCREEN ON THE INNER SURFACE OF THE FACE PORTION OF SAID ENVELOPE, SAID PHOSPHOR SCREEN INCLUDING A PLURALITY OF PHOSPHORS WHICH EMITS LIGHT OF DIFFERENT COLORS WHEN STRUCK BY ELECTRONS OF DIFFERENT ENERGIES, A FIRST CONDUCTIVE BAND AROUND THE INNER SURFACE OF THE INTERMEDIATE PORTION OF SAID ENVELOPE ADJACENT SAID PHOSPHOR SCREEN AND ELECTRICALLY CONNECTED THERETO FOR APPLYING ELECTRON ACCELERATING VOLTAGES TO THE SCREEN, A SINGLE ELECTRON GUN IN THE NECK PORTION OF SAID ENVELOPE FOR EMITTING A BEAM OF ELECTRONS TOWARD SAID SCREEN, A SECOND CONDUCTIVE BAND AROUND THE INNER SURFACE OF THE INTERMEDIATE PORTION OF SAID ENVELOPE ADJACENT SAID NECK PORTION FORMING A GENERALLY ANNULAR ELECTRODE WHICH IS SUBSTANTIALLY CONCONCENTRIC WITH SAID GUN AND AXIALLY DISPLACED THEREFROM TOWARD SAID SCREEN, A THIRD CONDUCTIVE BAND SUBSTANTIALLY EQUIDISTANTLY SPACED OUTWARDLY AWAY FROM SAID FIRST BAND AND IN SUBSTANTIAL JUXTAPOSITION THEREWITH, SAID FIRST AND THIRD BANDS FORMING WITH SAID ENVELOPE A CAPACITOR FOR COUPLING TIME-VARYING SIGNALS FROM SAID THIRD BAND TO SAID FIRST BAND, AND A FOURTH CONDUCTIVE BAND SUBSTANTIALLY EQUIDISTANTLY SPACED OUTWARDLY AWAY FROM SAID SECOND BAND AND IN SUBSTANTIAL JUXTAPOSITION THEREWITH SAID SECOND AND FOURTH BANDS FORMING WITH SAID ENVELOPE A CAPACITOR FOR COUPLING TIME-VARYING SIGNALS FROM SAID FOURTH BAND TO SAID SECOND BAND; MEANS FOR APPLYING D.C. BIAS VOLTAGE TO SAID FIRST AND SECOND BANDS TO ACCELERATE ELECTRONS EMITTED FROM SAID GUN TOWARD SAID SCREEN; FIELD GENERATING MEANS FOR DEFLECTING SAID BEAM OF ELECTRONS IN A SCANNING RASTER; AND MEANS FOR APPLYING OUT-OF-PHASE TIME-VARYING VOLTAGES TO SAID THIRD AND FOURTH BANDS WHEREBY ELECTRONS EMITTED FROM SAID GUN ARE ACCELERATED TO AT LEAST TWO DIFFERENT ENERGIES FOR ENERGIZING SAID SCREEN TO PRODUCE MULTIPLE-COLOR IMAGES HAVING COLOR IMAGE COMPONENTS WHICH ARE IN SUBSTANTIAL REGISTRATION.
