ABSTRACT:
A single-tube type projection display with high light efficiency includes phosphors of three primary colors formed on upper, middle and lower portions of a faceplate of a CRT. Images of three colors are projected on the phosphor layers, and a color picture is obtained by overlapping the three color images on the screen by the projection lenses.
