Abstract: An electron gun assembly for a cathode ray tube where the distortion of the electron beam that ordinarily occurs at the periphery of the screen is reduced. The electron gun assembly includes a cathode for emitting electrons, and a plurality of grid electrodes having a control electrode facing the cathode. The grid electrodes sequentially follow the cathode to focus and accelerate the electrons emitted from the cathode. The control electrode has a beam passage hole with a horizontal length H, and a vertical length V being larger than the horizontal length H. The ratio of the vertical to horizontal lengths satisfies the following condition: 1.03?V/H?1.63.

Abstract: An electron gun assembly for a cathode ray tube includes a cathode for emitting an electron beam, and a plurality of electrodes mounted in a row with predetermined gaps therebetween. The electrodes include a focus electrode for receiving a focus voltage, and an anode electrode surrounding part of the focus electrode for receiving an anode voltage. A support is used to fix the electrodes in an aligned configuration, and a first auxiliary support secures the focus electrode to the support. The focus electrode includes an intermediate aperture section, a small aperture section, and a large aperture section, while the anode electrode includes a large aperture section and a small aperture section. Two second auxiliary supports secure the anode electrode to the support.

Abstract: An electron gun for a cathode ray tube having a scanning velocity modulation coil mounted on an outer circumference of a neck of the cathode ray tube. The electron gun includes a cathode for emitting electron beams; a plurality of grid electrodes sequentially mounted starting from the cathode, and including a plurality of focus electrodes mounted with a predetermined gap therebetween; supports on which the grid electrodes are fixed in a row; and a shield electrode mounted between the focus electrodes and connected to the focus electrodes. The shield electrode defines a continuous space along an elongated axis direction of the cathode ray tube.

Two second auxiliary supports extend toward the cathode while maintaining a distance between each other that is smaller than an inner diameter of the large aperture section. The combined width of the focus electrode and the first auxiliary support is less than the inner diameter of the large aperture section of the anode electrode.
