Abstract

An improved method of manufacturing a cathode ray tube for displaying color images and comprising an image display having a large number of triplets, each consisting of three linear luminescent emitting regions in different collars, media to generate three electron beams and a color selection electrode having a large number of substantially parallel grooves, to assign each electron beam to luminescent regions of a color such that each triplet corresponds to one groove, in which method, To provide the luminescent regions of each color, a photosensitive layer is exposed through the color selection electrode from at least two positions such that light beams passing through two juxtaposed grooves overlap each other on the layer. photosensitive and an unexposed region is formed, where the luminescent regions of the mentioned color have to be provided on the photosensitive layer, between the light beams that pass through the same slot, characterized in that before arranging the luminescent regions, the photosensitive layer is fully exposed through the color selection electrode in the triplet regions that they correspond to the outermost slot minus one, on both sides of the color selection electrode, as well as in the region between the last mentioned triplets, after which a non-luminescent layer is provided on the unexposed parts of the layer photosensitive.
