In an embodiment, the device comprises ten rows of ten cathode-ray tubes, each tube being associated with a convergent lens. Each cathode-ray tube reproduces a picture portion and the lens enlarges this picture portion in such a ratio that the joints between the cathode-ray tubes no longer appear. The cathode-ray tubes incorporate a single electron gun, two pairs of electrostatic deflection plates and a screen incorporating red, green and blue phosphors abnd ultraviolet indexing phosphors. The display device is connected to an electronic device which supplies scan signals for each cathode-ray tube and which supplies color signals. The horizontal-scan frequency and vertical-scan frequency are ten times higher than for a conventional television display. The electronic device possesses memories which store the color information corresponding to each of the picture portions. |
