Abstract

PURPOSE: To realize the projection of a large-screen color TV picture image featuring a high resolution by means of the color Braun tube of a low resolution and the monochrome Braun tube of a high resolution.
CONSTITUTION: Color Braun tube 1 possesses the red, green and blue fluorescent substances plus the color identifying electrode such as the shadow mask or the like. And each fluorescent substance is excited by the color difference signal, and the picture formed by the color difference signals is projected on the fluorescent screen of tube 1. On the other hand, monochrome Braun tube 2 is excited by the luminance signal, and the monochrome picture formed by the luminance signals is projected on the fluorescent screen of tube 2. Then each picture is projected with magnification on screen 7 via the Schmidt optical system comprising Schmidt reflectors 3 and 4 plus correction lenses 5 and 6. Both the color and monochrome pictures projected with magnification are compounded on screen 7, thus obtaining a large-sized color picture image.
