Electroluminescent scanning and display system

Claim 1

A COMBINATION COMPRISING: PHOSPHOR MEANS FOR EMITTING LIGHT WHEN A POTENTIAL DIFFERENCE IS APPLIED ACROSS IT; A FIRST CONDUCTOR ON ONE SIDE OF SAID PHOSPHOR MEANS; SAID FIRST CONDUCTOR BEING CAPABLE OF PASSING LIGHT; A SECOND CONDUCTOR ON A SECOND SIDE OF SAID PHOSPHOR MEANS; SAID FIRST AND SECOND CONDUCTORS BEING POSITIONED SUCH THAT AT LEAST PART OF A POTENTIAL DIFFERENCE BETWEEN SAID FIRST AND SAID SECOND CONDUCTORS IS APPLIED ACROSS AND PHOSPHOR MEANS; SAID PHOSPHOR MEANS, FIRST CONDUCTOR, AND SECOND CONDUCTOR BEING POSITIONED WITH RESPECT TO ONE ANOTHER SO AS TO FORM A DISPLAY SURFACE BOUNDED BY A PLURALITY OF EDGES AND HAVING A FRONT SURFACE ON WHICH A SPOT OF LIGHT EMITTED BY SAID PHOSPHOR MEANS MAY BE DISPLAY THROUGH SAID FIRST CONDUCTOR; SAID EDGES BEING TERMINATED IN THE CHARACTERISTIC IMPEDANCE OF THE TRANSMISSION LINE FORMED BY SAID FIRST AND SECOND CONDUCTORS AND SAID PHOSPHOR MEANS; A FIRST, SECOND, AND THIRD TERMINAL ADAPTED TO RECEIVE VOLTAGE PULSES; FIRST CONDUCTOR MEANS FOR CONDUCTING ELECTRICAL ENERGY FROM SAID VOLTAGE PULSES TO A SUBSTANTIAL AREA OF A FIRST OF SAID EDGES OF SAID DISPLAY SURFACE THROUGH A RIST PULRALITY OF DIFFERENT PATHS FROM SAID FIRST TERMINAL TO SAID FIRST EDGE; EACH OF SAID FIRST PLURALITY OF PATHS HAVING SUBSTANTIALLY THE SAME TIME DIAPLY FORM SAID FIRST TERMINAL TO SAID FIRST EDGE FOR SAID ELECTRICAL ENERGY; SECOND CONDUCTOR MEANS FOR CONDUCTING ELECTRICAL ENERGY FROM SAID VOLTAGE PULSES TO A SUBSTANTIAL AREA OF A SECOND OF SAID EDGES OF SAID DISPLAY SURFACE THROUGH A SECOND PULRALITY OF DIFFERENT PATHS FROM SAID SECOND TERMINAL TO SAID SECOND EDGE; EACH OF SAID SECOND PLURALITY OF PATHS HAVING SUBSTANTIALLY THE SAME TIME DELAY FROM SAID SECOND TERMINAL TO SAID SECOND EDGE FOR SAID ELECTRICAL ENERGY; THIRD CONDUCTOR MEANS FOR CONDUCTING ELECTRICAL ENERGY FROM SAID VOLTAGE PULSES TO A SUBSTANTIAL AREA OF A THIRD OF SAID EDGES OF SAID DISPLAY SURFACE THROUGH A THIRD PLURALITY OF DIFFERENT PATHS FROM SAID THIRD TERMINAL TO SAID THRID EDGE; SAID SECOND EDGE BEING SUBSTANTIALLY PARALLEL TO SAID FIRST EDGE AND SAID THIRD EDGE BEING SUBSTANTIALLY PERPENDICULAR TO SAID FIRST EDGE; GENERATOR MEANS FOR GENERATING A.C. VOLTAGE PULSES HAVING A WAVELENGTH AT LEAST AS LONG AS ONE HALF OF THE SHORTEST DISTANCE BETWEEN ANY TWO PARALLEL EDGES OF SAID DISPLAY SURFACE; FIRST AND SECOND VARIABLE DELAY LINES ELECTRICALLY CONNECTED TO SAID FIRST AND SECOND TERMINALS RESPECTIVELY; AND GATE MEANS FOR ALTERNATELY PASSING THE GROUP OF POSITIVE PULSES FROM SAID A.C. PULSES AND A GROUP OF NEGATIVE PULSES FROM SAID A.C. PULSES; SAID GATE MEANS CONNECTING SAID ALTERNATE GROUPS OF POSITIVE AND NEGATIVE PULSES TO SAID FIRST VARIABLE DELAY LINE, TO SAID SECOND VARIABLE DELAY LINE, AND TO SAID THIRD TERMINAL, WHERBEY SAID PULSES RESULT IN A SPOT OF LIGHT ON SAID DISPLAY SURFACE CAUSED BY STANDING WAVES FROM SAID ELECTRICAL ENERGY TRANSMITTED TO SAID FIRST AND SECOND CONDUCTORS BY SAID FIRST, SECOND, THIRD CONDUCTOR MEANS AT A LOCATION DETERMINED BY THE AMOUNT OF DELAY IN SAID FIRST AND SECOND VARIABLE DELAY LINES.
