Transparent electronic display systems

Claim 1

AN ELECTRONIC SYSTEM FOR DISPLAYING A PATTERN OF ILLUMINATED SPOTS ON A GAS FILLED MATRIX HAVING SERIES OF MUTUALLY CROSSED COORDINATE CONDUCTORS IN RESPONSE TO GROUPS OF INPUT VIDEO SIGNAL SEPARATED BY SYNCHRONIZING PULSES, THE SIGNALS BEING CONNECTED TO SAID CROSSED CONDUCTORS, SAID SYSTEM COMPRISING SEPARATE COMMUNICATING MEANS EACH CONNECTED WITH ONE OF SAID SERIES OF CROSSED CONDUCTORS AND SEQUENTIALLY APPLYING TO THE CONDUCTORS IN EACH SERIES BIAS VOLTAGES HAVING AMPLITUDES LESS THAN THE THRESHOLD VOLTAGE NECESSARY TO IONIZE THE GAS BETWEEN CROSSED CONDUCTORS, AT LEAST ONE OF SAID COMMUTATING MEANS COMPRISING A BIAS PULSE GENERATOR SYNCHRONIZED TO SAID SYNCHRONIZING PULSES, A BIAS-PULSE DELAY LINE COUPLED WITH SAID PULSE GENERATOR AND HAVING TAPS CONNECTED WITH THE ASSOCIATED SERIES OF CONDUCTORS AND SEQUENTIALLY APPLYING THE BIAS PULSE THERETO; AND COMPENSATING MEANS GENERATING A CONTINUOUSLY INCREASING COMPENSATING VOLTAGE BETWEEN SYNCHRONIZING PULSES AND APPLYING SAID COMPENSATING VOLTAGE BETWEEN THE CONDUCTORS OF THE CROSSED SERIES TO COMPENSATE FOR PULSE AMPLITUDE DECREASES AS EACH PULSE PASSED ALONG THE DELAY LINE.
