Method of screening a cathode-ray tube
Abstract
Abstract THE IMAGE AREA OR SCREEN OF A COLOR CATHODE-RAY TUBE RECEIVES BY ELECTROPHOTOGRAPHIC DEPOSITION DEPOSITS OF VARIOUS PHOSPHOR MATERIALS ARRANGED THEREOVER IN A REGULAR INTERLACED PATTERN. THEREAFTER, THE SCREEN AREA IS RECHARGED TO DEVELOP AN ELECTRIC FIELD FOR HOLDING THE PHOSPHOR DEPOSITS IN PLACE. NEXT, A FIXER, COMPRISING A CARRIER LIQUID AND A RESINOUS BINDER PARTIALLY IN SOLUTION AND PARTIALLY IN SUSPENSION, IS APPLIED TO THE SCREEN. THE FIXER HAS A HIGH ELECTRICAL VOLUME RESISTIVITY TO THE END THAT THE CHARGE ON THE COATED AREA IS RETAINED, CAUSING THE ELECTRIC FIELD TO RESIST THE TENDENCY OF MECHANICAL FORCES INCIDENT TO THE APPLICATION OF THE FIXER TO DISPLACE THE INDIVIDUAL PHOSPHOR DEPOSITS FROM THEIR ASSIGNED POSITIONS.
