Color kinescope display system

Claim 1

IN A SYSTEM FOR DISPLAYING COLOR IMAGES IN RESPONSE TO CORRELATED LUMINANCE AND CHROMINANCE INFORMATION COMPRISING A COLOR IMAGE REPRODUCING DEVICE HAVING MEANS FOR GENERATING A BEAM OF ELECTRONS, MEANS FOR CONTROLLING THE INTENSITY OF SAID BEAM OF ELECTRONS, AND A TARGET FOR SAID BEAM OF ELECTRONS, SAID BEAM TARGET COMPRISING AN ARRAY OF PHOSPHOR STRIPS OF DIFFERENT COLOR EMISSION CHARACTERISTICS ARRANGED IN A REPEATING SEQUENCE AND INCLUDING A PLURALITY OF INDEXING ELEMENTS IN ASSOCIATION WITH SAID PHOSPHOR STRIPS; APPARATUS COMPRISING THE COMBINATION OF BEAM DEFLECTION MEANS FOR CAUSING SAID BEAM OF ELECTRONS TO TRACE A SUCCESSION OF SUBSTANTIALLY PARALLEL SCANNING LINES ON SAID TARGET TRANSVERSELY WITH RESPECT TO THE PHOSPHOR STRIPS OF SAID ARRAY, THE TRACING OF SAID SCANNING LINES CAUSING SUCCESSIVE BEAM TRAVERSALS OF SAID INDEXING ELEMENTS; MEANS RESPONSIVE TO THE BEAM TRAVERSALS OF SAID INDEXING ELEMENTS FOR DEVELOPING AN INDEXING WAVE OF A FUNDAMENTAL FREQUENCY NOMINALLY EQUAL TO THE FREQUENCY AT WHICH SUCCESSIVE PHOSPHOR STRIPS OF A GIVEN ONE OF SAID DIFFERENT COLOR EMISSION CHARACTERISTICS ARE TRAVERSED BY SAID BEAM; MEANS COUPLED TO SAID FUNDAMENTAL FREQUENCY INDEXING WAVE DEVELOPING MEANS FOR DEVELOPING A SECOND INDEXING WAVE OF A FREQUENCY SUBSTANTIALLY EQUAL TO THE SECOND HARMONIC OF SAID FUNDAMENTAL FREQUENCY; MEANS FOR VARYING THE VELOCITY AT WHICH SAID BEAM TRACES SAID SCANNING LINES; MEANS COUPLED TO SAID BEAM INTENSITY CONTROLLING MEANS FOR UTILIZING THE SECOND HARMONIC INDEXING WAVE DEVELOPED BY SAID SECOND-NAMED DEVELOPING MEANS TO MODULATE THE INTENSITY OF SAID ELECTRON BEAM; AND MEANS COUPLED TO SAID LINE SCANNING VELOCITY VARYING MEANS FOR UTILIZING THE FUNDAMENTAL FREQUENCY INDEXING WAVE DEVELOPED BY SAID FIRST-NAMED DEVELOPING MEANS TO MODULATE THE LINE SCANNING VELOCITY OF SAID ELECTRON BEAM; SAID APPARATUS ALSO INCLUDING MEANS RENDERING BOTH OF SAID INDEXING WAVE UTILIZING MEANS RESPONSE TO SAID CHROMINANCE INFORMATION IN SUCH MANNER THAT EACH OF THE RESPECTIVE INDEXING WAVES UTILIZED FOR BEAM MODULATION THEREIN IS MODULATED IN ACCORDANCE WITH CHROMINANCE INFORMATION.
