초록

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.

청구항

A flat display device comprising an evacuated envelope having a plurality of spaced supports which contact a screen bearing wall of the envelope, said screen including a mosaic of repetitive groups of different color emitting phosphor bodies with a selective one of the same color emitting phosphor bodies of some of the groups being replaced by a body of a nonluminous material, each of the supports being positioned at a separate nonluminous material body.
