Abstract

PURPOSE: To establish suitable color picture, by providing the black fine stripes the same as the profile of light emission region of the face of a receiving tube in front of the receiving tube, and taking the transparent scatter plane between the fine stripes and the buffer optical system.
CONSTITUTION: The face 2 is covered with the transparent type scatter plate 8 having the same shape window 9 as the light emission region 2a of a receiving tube. Black paint is coated along the inner edge of the plate 8, forming the fine stripes 10 and constituting the buffer video inner edge. The width of fine stripes is around 1.5 mm for a 20 inch receiving tube. Further, in closely contacting the plate 8 on the plane 2, the straight line tying the end of the fluorescent substance film 6 and the inner edge of the fine stripes 10 makes an angle θ(2' to 4') to the normal line of the plane 2, so that the non-light emission region is hidden with the plate 8 and the fine stripes 10 at a suitable observing distace. Next, the box 3 made of transparent plates 3 is attached on the plane 2. Frennel convex lens 11 is laminated, further it is fixed on the case 4, and external frame 13 is attached. With this construction, the quality of picture can be improved more.
