Abstract

The invention describes a cathode ray tube wherein the position of the electron beam (7, 8, 9) is determined in that detection strips (12, 13) of a light-emitting material are arranged between the individual phosphor segments (17, 18, 19) of the segmented phosphor layer (11). The detection strips (12, 13) comprise strip-shaped sections containing the same light-emitting material, the length of the strip-shaped sections of the first set of detection strips being different from the length of the strip-shaped sections of the second set of detection strips.
