ABSTRACT:
The present invention is directed to a method for producing patterned color-triad arrays in glass for use in color television picture tubes, such arrays being capable of acting as spectrally-selective filters and to provide the desired color information when the television tube is operating. The color-triad arrays are produced by sequentially or simultaneously exposing a polychromatic glass through an electron shadow mask to high energy or actinic radiation and thereafter following the heat treatment and re-exposure practice known to develop colors within polychromatic glass. The filtering action provided by the color triads integrally present within the glass can enhance the contrast of the color image produced. Also, the presence of the color triads in the glass permits the use of a single "white" phosphor, rather than a red, a green and a blue phosphor as are presently used in the conventional color television picture tube.
