摘要： A color picture tube device that can adjust convergence without causing increases in cost and in power consumption is provided. One pair of magnetic flux generation means for generating a static quadrupole magnetic field are positioned above and below an area where a plurality of electron beams pass through. The static quadrupole magnetic field has an effect of adjusting convergence in a horizontal direction. In this construction, a magnetic flux generated by one of the two magnetic flux generation means that is closer to the plurality of electron beams is reduced, in sync with deflection of the plurality of electron beams in a vertical direction.

摘要： A signal is sent to a deflection circuit and a video signal processing circuit. On receiving the signal, the deflection circuit outputs a vertical deflection signal and a horizontal deflection signal. The vertical deflection signal is sent directly to a deflection yoke while the horizontal deflection signal is sent via an S-shaped wave modulation circuit to the deflection yoke. On the other hand, the video signal processing circuit receives the signal and outputs a video signal via an amplitude modulation circuit and a frequency modulation circuit to a cathode of an electron gun. The S-shaped wave modulation circuit performs modulation on the horizontal deflection signal to change scanning speed. The amplitude modulation circuit and the frequency modulation circuit perform, on the video signal, amplitude modulation and frequency modulation which are appropriate for this speed.

摘要： A color picture tube device has a funnel glass, a pair of horizontal deflection coils, an insulating frame, and a pair of vertical deflection coils. The pair of horizontal deflection coils are opposed to each other in a vertical direction around the outer surface of the funnel glass, and each have a window at the center. The insulating frame covers the horizontal deflection coils, resembles in shape a part of the funnel glass where the horizontal deflection coils are provided, and has openings in areas corresponding to windows of the horizontal deflection coils. The pair of vertical deflection coils are opposed to each other in a horizontal direction around the outer surface of the insulating frame, without overlapping the openings. In this color picture tube device, a pair of correction coils are provided so as to be each at least partially inserted in a different one of the openings.

摘要： A color picture tube device that can suppress the deformation of the electron beam spot shape and improve the horizontal resolution using a simple construction is provided. A horizontal deflection coil generates a horizontal deflection magnetic field that is substantially uniform. A plurality of electron beams are substantially parallel with the tube axis when passing one end of a core of a deflection yoke facing an electron gun. A lens forming unit forms a lens through which the plurality of electron beams pass, between the electron gun end of the core and a phosphor screen. The lens has an effect of causing the plurality of electron beams to approach each other in a horizontal direction, irrespective of which part of the phosphor screen the plurality of electron beams reach.

摘要： In a color CRT apparatus in which three electron beams 4, 5, 6 are not superimposed on one point on the screen 11 at a time, a time difference is applied to modulating signals 12, 13, 14 corresponding to the respective electron beams to adjust phase, thus achieving convergence of images, the screen is flat, both a horizontal magnetic deflection field and a vertical magnetic deflection field have uniform magnetic field distribution, paths of both side electron beams and a path of the center electron beam of the three electron beams 4, 5, 6 emitted from electron sources 1, 2, 3 are approximately parallel, and the time difference applied to the modulating signals is set to be approximately constant throughout the screen 11. Thus, images formed of imaging spots of the three electron beams can be superimposed on the screen with high precision to be matched without causing increased cost. Consequently, it is possible to cope sufficiently with the increased display density of image information and increased deflection angle due to the reduction in depth of the color CRT apparatus.

摘要： A color picture tube device in which a lens is generated in an area through which a plurality of electron beams pass, so as to be positioned, in a tube axis direction, between a phosphor screen and an end of a core nearest the electron gun. The lens has a horizontal focusing effect that focuses each of the electron beams in the horizontal scanning direction. Furthermore, an interval between at least the two outermost of the plurality of electron beams is adjusted, so that the interval at a time of the electron beams entering the lens widens as the degree of horizontal deflection by a horizontal deflection coil increases.
