Electro-optical device
Abstract
Abstract AN ELECTRO-OPTICAL DEVICE HAVING A PLURALITY OF SUPERIMPOSED LAYERS, AND INCLUDING A CENTRAL PANEL HAVING A PLURALITY OF DISCRETE BORES EXTENDING THERETHROUGH TO FORM DISPLAY CELLS FOR RECEIVING AND RETAINING AN ELECTRO-OPTICAL SUBSTANCE, WHICH SUBSTANCE MAY INCLUDE AN IONIZABLE GASEOUS FILL, AND A PLURALITY OF SCANNING ELECTRODES ON OPPOSITE SIDES OF SAID CELLS FOR APPLYING AN ELECTRICAL FIELD THROUGH EACH OF SAID CELLS. THE DISPLAY CELLS ARE ARRANGED IN GROUPS OF ROWS AND COLUMNS, AND SCANNING ELECTRODES EXTEND BEYOND THE AREA OF THE CELLS AND INTO A REMOTE CHAMBER, WHEREIN A GAP IS FORMED IN THE CONTINUITY OF EACH OF THE SCANNING ELECTRODES. THESE GAPS ARE ARRANGED IN TWO GROUPS OR BANKS, ONE GROUP FOR THE ROWS, THE OTHER FOR THE COLUMNS. A MAGNETIC DRIVE MEANS IS PROVIDED TO GENERATE A FIELD WHICH IS COUPLED TO THE GAPS IN THE INDIVIDUAL GROUPS, AND MEANS ARE PROVIDED FOR ENERGIZING THE MAGNETIC MEANS TO INTERMITTENTLY STEP AN ARC FORMED IN THE GAPS FROM ONE GAP PAIR TO ANOTHER GAP PAIR ALONG THE GAP AXIS.
