Abstract

PURPOSE: To correct the slope of luminance on the fluorescent screen not by electric signal but by optical means.
CONSTITUTION: In a projective type receiver consisting of the receiving tubes of red, green and blue, on the front glass 5 of the receiving tube located at the both sides, the correction of luminance body 6 is made by coating and diffusing ooaque substance such as metal and metal oxide with the distribution of thickness of a wedge. When this corrective substance is placed bwteen the projective type receiving tube and the screen, the slope of luminance is corrected into uniform value, then the deterioration in the fluorescent screen can be prevented.
