Method of depositing phosphor on cathode ray tube target
Abstract
Abstract A STORGAE TARGET FOR A CATHODE RAY TUBE INCLUDES A GLASS SUPPORT PLATE HAVING A MULTIPLICITY OF DEPRESSION INTO WHICH PHOSPHOR STORAGE DIELECTRIC IS DIFFERENTIALLY DEPOSITED. THE TARGET IS MADE BY IMMERSING THE PLATE IN A VOLATILE LIQUID MEDIUM AND FINE PHOSPHOR PARTICLES ARE DISPERSED IN SUCH MEDIUM IN A MANNER TO PROVIDE TURBULENT MOVEMENT OF THE PHOSPHOR PARTICLES IN THE MEDIUM. THE LIQUID MEDIUM HAS THE PROPERTY, IN COMBINATION WITH THE PHOSPHOR PARTICLES, OF CAUSING THE PHOSPHOR PARTICLES TO ASSUME A CHARGE RELATIVE TO THE MEDIUM SUCH THAT THE PHOSPHOR PARTICLES MOVE TOWARD AND SETTLE IN THE AFOREMENTIONED DEPRESSIONS, WHILE SUBSTANTIALLY AVOIDING A TARGET MESH ELECTRODE OR THE LIKE BETWEEN DEPRESSIONS.
