摘要： Disclosed is a cathode ray tube and an 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 (S107). Any of the factors at the other signal levels is obtained by performing an interpolating operation (S105) 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.

摘要： An image display device (1) which includes a cathode ray tube is provided with a cathode system (2) for the emission of a plurality of electron beams (3) whereby a phosphor screen (4) is scanned in order to display an image. The electron beams are modulated on the basis of an electronic image signal by means of a cathode modulator (5). The cathode modulator is arranged to scan different image lines simultaneously by means of separate electron beams. For example, the cathode modulator comprises an extension system (7) and a delay system (8) for deriving extended and delayed extended image line sections from image line sections of the electronic image signal. The cathode modulator also comprises a combination unit (9) for simultaneously supplying an extended image line section and a delayed image line section with which separate electron beams are modulated.

摘要： A flat panel type display comprising control electrodes each divided in the horizontal direction of the screen thereof and arranged in a vacuum casing, fluorescent material provided on each control electrode, mesh-like electrodes facing the fluorescent material, vertical scanning electrodes each facing the mesh-like electrodes and divided in the vertical direction of the screen thereof and an electron source for generating a plurality of electron beams continuously or discretely in the extension of space between a light emitting portion composed of the fluorescent material and a group of the vertical scanning electrodes in the horizontal direction of the screen thereof. Further, a partition made of insulating material is provided in the divided portion of each control electrode to increase the withstand voltage between each pair of the adjacent control electrodes, and a modulation signal is supplied to each control electrode. Alternatively, every n pieces of the control electrodes are connected to a bus to which a pulse voltage for causing the fluorescent material to emit light is applied. Furthermore, to a first vertical scanning electrode in the side, where an electron beam going straight on is incident, is applied a voltage, of which the magnitude (V
D ) is equal to a voltage applied to the fluorescent screen or the mesh-like electrodes. Then, to a predetermined number of the vertical scanning electrodes subsequent to the first vertical scanning electrode in the direction in which the electron beam goes straight on, is applied a voltage of which the magnitude (V
D -V
CC ) is less than the voltage applied to the fluorescent screen. Thereafter, to a vertical scanning electrode subsequent to the predetermined number of the vertical scanning electrodes in the direction in which the electron beam goes straight on, is applied a voltage of which the magnitude (V
D - V
M ) is equal to or more than the voltage applied to the fluorescent screen or the mesh-like electrodes. Thus, the vertical scanning is performed.

摘要： Un système d'affichage plat en couleurs comprend un dispositif plat d'affichage en couleurs et un dispositif de commande dudit dispositif d'affichage. Le dispositif de commande comprend trois registres analogiques à décalage pour l'enregistrement des signaux analogiques d'images correspondant aux trois couleurs primaires. Les signaux analogiques sont lus dans ces registres selon un procédé ligne par ligne. L'avantage de l'utilisation d'un dispositif analogique d'enregistrement (13, 14, 15) au lieu d'un dispositif numérique consiste dans le fait que seul un convertisseur N/A (21) est nécessaire et que les signaux peuvent être aisément lus en parallèle. Selon un procédé spécial de commande, seul un tiers des électrodes des segments reçoit les signaux d'image. Un potentiel de blocage est appliqué aux autres segments situés entre les segments actifs qui reçoivent les signaux de couleurs.

摘要： A scanning beam display system includes an optical module (10; 110), an image control module (320), and a display screen (1; 101) on which optical beams (12; 120) are scanned. The optical module (10; 110) includes a vertical adjuster (340) placed in the optical paths of the beams (12; 120) to control and adjust positions of the optical beams (12; 120) along a generally vertical direction on the display screen (1; 101), and a control unit (380) configured to receive control instructions for the vertical adjuster (340) and to control the vertical adjuster (340) to be at one of a predetermined number of orientations to place the scanning optical beams (12; 120) at a corresponding distinct position on the display screen (1; 101). The control unit (380) is further configured to apply an adjustment offset to each orientation of the vertical adjuster (340) such that each immediately vertically adjacent pair of beam footprints (412) projected on the display screen (1; 101) resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

摘要： A multi-beam electron gun (31) of the invention emits two electron beams (1a,1b) for each of the three colors, red, green and blue, from the top and the bottom. A single composite screen is formed as a whole at a display screen (14) by the electron beam group (Ia) on the top and the electron beam group (1b) on the bottom. Image distortion in all of the scanning screens formed by the electron beam group on the top and the electron beam group on the bottom are corrected by directly correcting the image data by correcting means (55-65) based on correction data stored in a storing means (60). At this time, correction of the image data is separately performed on the data for each electron beam, and is performed by changing the arrangement of pixels in terms of space and time. Thereby, image display using the multi-beam electron gun can be excellently performed.

摘要： A control portion detects a level of video signals for each color when video signals are inputted from a frame memory to DSP circuits. Next, the control portion calculates an appropriate correction coefficient of each color to be used in modulation control of brightness, for every unit pixel or unit pixel array among a plurality of correction coefficients stored in its own memory in advance based on the detected signal level. The control portion instructs the DSP circuits to perform modulation of brightness by using the determined correction coefficient.
