Large sized screen display device by cathode ray tube

Abstract

Abstract PURPOSE:To realize a large sized color display device in which lots of cathode ray tubes are arranged in parallel by providing sets of transparent rods to a front face of each image receiving face dense to the image receiving face and arranging a pointed end of a transparent rod of one image receiving face at a border in contact with other image receiving face in almost tangential direction to a pointed end of a transparent rod of other image receiving face so as to eliminate blacky (dark) joints of the picture. CONSTITUTION:Sets 3 of transparent rods 30 are provided densely along a curved face of a front face glass 5 of a cathode ray tube and tips 4, 40 of the transparent rods of adjacent cathode ray tubes are directed in a direction close to each other. The front glass 5 of the cathode ray tube swollen remarkably is formed thin, the transparent rod 30 is short in the middle of the front face glass 5, long at the circumferential ridge and radiation faces X...X are formed almost flat. The sets of the transparent rods are formed separately in a block as 3a, 3b, 3c, 3d... and the blocks are bound by a band 8 to form one block B. The blocks B are laminated in multi-stage and formed to the radiation faces X...X.
