Abstract

PURPOSE:To eliminate a change of hue that is turned by the point of watching, by making the optical axes of projection into one axis with use of an optical fiber. CONSTITUTION:One end of each of optical fiber bundles 8-10 is attached in the same direction as the horizontal scanning direction at the front faces of monochrome cathode-ray tubes 2-4 that emit the lights of red, green and blue each. The other end of each of these optical fiber bundles is put in front of a projection lens 11 to compose of the three colors. Thus the optical axes of these monochrome cathode-ray tubes are unified into one axis.
