Abstract

PURPOSE:To obtain a bright image free of color aberration by only one projection type cathode-ray tube by a method in which a target arranged in the face of a concaved spherical mirror is turned at its axle as the center. CONSTITUTION:The mirror 15 is formed on the inner surface of the concaved spherical end plate 10, and the target 17 is arranged in a face-to-face relation with the mirror 15. The target 17 is of a column from having faces as many as a multiple of three. The surfaces are concaved and each of them is coated with red-, green-, and blue-luminescent fluorescent substances in order. A color image is reproduced by turning the target 17.
