Electroluminescent panel driver circuits

Claim 1

A TWO-DIMENSIONAL DISPLAY SYSTEM COMPRISING AN ELECTROLUMINESCENT PANEL INCLUDING AN ARRAY OF FIRST SPACED LINES EXTENDING IN A FIRST DIRECTION AND AN ARRAY OF SPACED SECOND LINES EXTENDING IN A SECOND DIRECTION, EACH OF SAID FIRST LINES CROSSING SAID SECOND LINES TO FORM A PLURALITY OF CROSSOVER POINTS, AND A LAYER OF ELECTROLUMINESCENT MATERIAL DISPOSED BETWEEN SAID ARRAYS OF LINES, A PLURALITY OF FIRST DRIVERS EACH COUPLED TO A CORRESPONDING ONE OF SAID FIRST LINES, A PLURALITY OF SECOND DRIVERS EACH COUPLED TO A CORRESPONDING ONE OF SAID SECOND LINES, FIRST CIRCUIT MEANS FOR SELECTIVELY APPLYING A FIRST GATING PULSE TO A SELECTED ONE OF SAID FIRST DRIVERS CORRESPONDING TO THE FIRST LINE TO BE SELECTED, SECOND CIRCUIT MEANS FOR SELECTIVELY APPLYING A SECOND GATING PULSE TO A SELECTED ONE OF SAID SECOND DRIVERS CORRESPONDING TO THE SECOND LINE TO BE SELECTED, EACH OF SAID FIRST DRIVERS BEING NORMALLY PRODUCTIVE OF A FIRST VOLTAGE OUTPUT ON SAID CORRESPONDING ONE OF SAID FIRST LINES, EACH OF SAID FIRST LINE DRIVERS BEING RESPONSIVE TO SAID FIRST GATING PULSE FOR PRODUCING A SECOND VOLTAGE OUTPUT ON SAID CORRESPONDING ONE OF SAID FIRST LINES, EACH OF SAID SECOND LINE DRIVERS BEING NORMALLY PRODUCTIVE OF A THIRD VOLTAGE OUTPUT ON SAID CORRESPONDING ONE OF SAID SECOND LINES, EACH OF SAID SECOND LINE DRIVERS RESPONSIVE TO SAID SECOND GATING PULSE TO PRODUCE A FOURTH VOLTAGE OUTPUT ON SAID CORRESPONDING ONE OF SAID SECOND LINES, SAID FOURTH VOLTAGE OUTPUT AND SAID FIRST VOLTAGE OUTPUT AT THE CROSSOVERS OF A SELECTED SECOND LINE AND UNSELECTED FIRST LINES PRODUCE A VOLTAGE DIFFERENTIAL WHICH IS BELOW THAT NECESSSARY FOR ESTABLISHING LUMINESCENCE OF SAID ELECTROLUMINESCENT MATERIAL, SAID SECOND VOLTAGE OUTPUT AND SAID THIRD VOLTAGE OUTPUT AT THE CROSSOVERS OF A SELECTED FIRST LINE AND UNSELECTED SECOND LINES PRODUCE A VOLTAGE DIFFERENTIAL WHICH IS BELOW THAT NECESSARY FOR ESTABLISHING LUMINESCENCE OF SAID ELECTROLUMINESCENT MATERIAL WHILE SAID SECOND VOLTAGE OUTPUT AND SAID FOURTH VOLTAGE OUTPUT AT THE CROSSOVER OF THE SELECTED FIRST LINE AND THE SELECTED SECOND LINE PRODUCE A VOLTAGE DIFFERENTIAL NECESSARY FOR ESTABLISHING LUMINESCENCE OF SAID MATERIAL THEREAT.
