Abstract

A storage target for a cathode ray tube is formed by adhering a layer of glass to the rear of a glass faceplate and etching depressions or apertures in such layer. Secondary emissive dielectric or phosphor material applied in these depressions will have uniform depth and therefore uniform storage properties. A storage target according to the present invention is provided with a collector on the glass layer between the apertures therein, as well as with an undercollector between the glass layer and the faceplate.
