Abstract

PURPOSE: To obtain bright brightness, excellent focussing, and less color change by the change of human eyes, by constituting the projection type color TV receivers with CRT having red and blue fluorescent screen and that having green fluorescent screen.
CONSTITUTION: The CRT 1RB of two beam type consists of the stripe fluorescent screen having red and blue black stripes and the CRT 1G of monochrome type is made up of the fluorescent screen having green and black stripes. The light of red and blue projected from the CRT 1B is projected on the screen 4 via the lens system 3RB, and that in green projected from the CRT 1G is via the lens system 3G. With this constitution, the remarkablity of video elements can greatly be reduced since red and blue as the video elements are not distinct and the light of red and blue from the CRT 1RB and the green light from the CRT 1G are seen as the ratio of synthesis for the stripes. Further, the two lens systems are in existence and the color change is less depending on the location of human eyes viewing the screen 4. Further, the brightness of the screen 4 is equal in case of three tube system.
