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.

摘要： A method of driving an image display device is disclosed in which electron beams from line cathodes (1) are impinged upon a display screen (9) through beam modulating and deflecting electrodes (6, 7, 7′, 8, 8′) to display an image. Each beam roughly lands onto a predetermined position on the screen by a stepped deflection voltage waveform to form a spot on the screen while the beam is deflected around the predetermined position by an unstepped deflection voltage waveform. The timing of application or the pulse width of a driving pulse signal for the beam modulating electrode is controlled in a form temporally related to the driving of the beam deflecting electrode to control the landing position or diameter of the spot on the screen. In the case where the driving pulse signal is a signal the pulse width of which is modulated by a video signal, the pulse width is changed in accordance with the level of the video signal and equally in positive and negative directions around the instant of time when a signal pulse having the minimum width necessary for representation as an image is to be generated.

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： 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.
