Abstract: A vacuum envelope of a cathode-ray tube includes a panel and a funnel section opposed to the panel. The funnel section has two funnels each having a cone section. Each of the funnels is formed by cutting one side portion of a base funnel which is formed by pressing. The two funnels are joined together at sections thereof so as to form the funnel section and also joined to the panel into the vacuum envelope. A neck containing an electron gun is joined to each of the cone sections. A phosphor screen formed on the inner surface has two scanning regions which are divided scanned by electron beams emitted from the electron guns.

Abstract: Disclosed is a cathode ray tube and a intensity controlling method achieving a reduced amount of factors for correcting intensity prepared and capable of performing proper intensity control so that the joint portion of split picture planes is inconspicuous from a viewpoint of intensity. With respect to the direction of overlapping a plurality of split picture planes, only correction factors at representative signal levels are pre-stored as a basic factor table. Any of the factors at the other signal levels is obtained by performing an interpolating operation using the basic factors in the basic factor table. The value of the signal level of a video signal referred to when the correction factor in the overlapping direction is obtained is changed by using a shift factor associated with the pixel position in the direction orthogonal to the overlapping direction. The basic factor is thereby changed according to the pixel position in the orthogonal direction.

Abstract: A cathode ray tube device has multiple elements for generating a display. Each of the relatively large number of elements has its own electron gun and deflection assembly. A large number of these subunits are connected into a regular array in which each unit generates a portion of the overall display. The individual gun and deflection assemblies are preferably formed in a framework which serves to both align and position the individual assemblies, and further to provide structural support for the evacuated tube.

Abstract: A CRT-matrix type big screen display system having self-emitting type picture cells is provided with a deflection waveform as a sawtooth waveform and a deflection waveform in the other direction as a step deflection waveform crossing the picture cells. Inclination of the scanning line is eliminated so that fluctuations in display brightness thereto are avoided and a satisfactory picture display is achieved. Also in CRT-matrix type big-screen display systems, index elements or cells are provided between sets of primary color cells and in the scanning direction. At least at the start of the scanning operation, the index elements or cells are scanned and the positional information thereof is stored in a memory for use in processing a video signal to achieve a satisfactory picture display. Furthermore, prior to reproducing a picture, a photo pickup equipment is slidably moved across the big screen and positional information of primary color cells sensed thereby is stored in a memory, which positional information is used in processing a video signal so that a satisfactory picture is displayed.
