Abstract

PURPOSE: To make a screen itself luminous with the objective luminance and hue to display the objective picture by arranging plural visible light fluorescent materials emitting visible light on the fixed region pattern of screen and exciting the fluorescent materials by means of invisible light.
CONSTITUTION: Plural kinds of visible light fluorescent materials R, G and B which emit respectively visible light with different kinds of have are arranged on screen 2 according to the fixed region pattern and, moreover, stripe invisible light fluorescent materials 6 and 7 which emit respectively invisible light with diffrent kinds of frequency spectrums are also coated. Invisible fluorescent materials 6 and 7 on screen 2 with the constitution above mentioned are scanned by deflecting ultraviolet rays beams UV supplied from luminous source 1 by the use of deflecting unit 3 and plural kinds of visible fluorescent materials R, G and B are excited by invisible light with wide frequency band width which is emitted from invisible fluorescent materials 6 and 7, so that the visible light with objective luminance and hue is emitted and are displayed on screen 2.
