Abstract
A technique has been developed whereby fine-detail printed patterns of color phosphors are deposited onto a glass surface suitable for use as the viewing screen in a color reproducer of the cathode-ray type. The phosphors, suspended in a lacquer, are squeegeed in turn through a stainless-steel-mesh-supported gelatin stencil. The lacquer is subsequently entirely removed by simple bakeout in air at elevated temperature. The glass plate is rigidly fixed by vacuum onto a table which can be accurately adjusted in two horizontal perpendicular directions. Exact position of the glass on the table is indicated by two dial gauges; the accuracy attained is such as to intermesh the three color phosphor patterns to better than 0.001 inch over the entire area. Phosphor screens have been made in substantial quantities for several types of color kinescopes, and have given very satisfactory performance.Keywords
