Abstract

PURPOSE: To use a current color TV system to operate a surroundings illuminating- type display device and simplify a circuit constitution by multiplexing illuminating signals into a color video sinal.
CONSTITUTION: Transparent screen 21 having window 20 corresponding to the video screen of color TV receiver 19 is arranged, and light stand 22 where three fluorescent tubes R, G and B generating three primary color lights are stored is provided in the upper face of receiver 19. Screen 21 is constituted by a milk-white scattering plate, and lights from fluorescent tubes R, G and B are projected onto screen 21 after being mixed by a fly eye lense which is provided in front of fluorescent tubes. Then, signals which modulate lights of fluorescent tubes to generate a desired illumination light are multiplexed to color video signals supplied to the receiver.
