ABSTRACT:
Across the screen is a mosaic of phosphor bodies which will emit light of different colors when excited by electrons. Phosphors which will emit three different colors, e.g. red, green and blue, are used and are disposed in a regular repetitive array of groups of three, i.e. triads. In every other triad the phosphor body which emits the color which has the least acuity to the eye, e.g. blue, is replaced by a nonluminescent black material. This black material is used to hide the edges of a support wall which extends to the screen.
