ABSTRACT:
A projection type color television system of the present disclosure comprises three cathode ray tubes for projecting a color picture on a projecting screen. The three cathode ray tubes have phosphor screens for producing and projecting onto the projecting screen respective three primary colors of light beam containing an image information in the beam. These cathode ray tubes are positioned with their respective phosphor screens placed on a first imaginary plane parallel to the projecting screen and in alignment with each other along a first imaginary line parallel to a horizontal scanning direction of the light beam. Of these tubes, a cathode ray tube producing a color having the highest amount of brightness measured in lumen is positioned intermediately between the other cathode ray tubes. Color signals applied to the two cathode ray tubes positioned one on each side of the intermediate cathode ray tube are corrected in such a manner that the ratio of the brightness of the primary colors is maintained at a predetermined ratio.
