Abstract

PURPOSE: To allow the actually sensed brightness of each luminous colour to be substantiailly equal by controlling the penetration characteristic of using filter, in using phosphorus having different luminous colours for separate anodes and operating the anode under the equal driving condition.
CONSTITUTION: A multicolour fluorescent indication tube is formed by setting in pile in succession on a substratum 11, each anode 13, 13' applied with phophorus 12, 12' each having different luminous colour a grid frame 14, and a grid 15, and further extending a cathode 16 through a supporting body 17, and piling-up a cover glass 18, and performing vacuum sealing with a frit glass 19. As for the phosphorus 12 and 12', the luminous phosphorus having different luminous characteristics each other are used, and the filters having the penetration rate inversely proportional to the actually sensed brightness of each luminous spectrum are used, and the actually sensed brightness of each luminous colour after passing through filter can be made substantially equal.
