Abstract

A cathode ray tube arrangement for displaying or displaying color images, comprising an image display having a large number of discrete or individual regions, which, when bombarded with electrons, glow in three different colors, a mask of color selection having a large number of openings, and means for producing three electron beams converging towards the image screen, each luminescent region being present in a path of an electron beam through one of said openings, being arranged said luminescent regions according to substantially parallel color bands, said color bands being arranged in trios, each comprising three bands of green, red and blue luminescence colors, respectively, characterized in that the central color band of each trio has red luminescence, and because, in at least part of the image display, the distance between the centers of two adjacent colored bands, of which one belongs to said trio and the other belongs to an adjacent trio.
