    摘要: A cathode ray tube (CRT) has an electron gun including a cathode for emitting electron beams, a control electrode for controlling emission of the electron beams from the cathode, and a screen electrode for accelerating the flow of the electron beams passing the control electrode are arranged in series. In the CRT, during a scanning period, a voltage applied to at least one of the control electrode and the screen electrode changes in response to a voltage of a data signal applied to the cathode. The control electrode and screen electrode each include three mutually electrically insulated sections for independently controlling each of three electron beams passing through the electrodes.

    摘要: An electron gun for a cathode ray tube includes a triode having cathodes, a first grid and a second grid, one or more third grids through which electron beams emitted from the cathode pass, a fourth grid opposing the third grids and forming a main focus lens with the third grid, a shield cup connected to the fourth grid and supplying a high voltage to the fourth grid, and a correction grid disposed between the fourth grid and the shield cup and having R, G, and B beam through holes arranged along a line. The R and B beam through holes have openings with asymmetrical shapes that are symmetrical with respect to each other and relative to the straight line, balancing astigmatisms and improving resolution.

    摘要: An electron gun for a cathode ray tube has a cathode structure, a control electrode, a screen electrode, focusing electrodes, and a final accelerating electrode. R, G, and B electron apertures of one pair of the focusing electrodes face each other to form a quadrupole lens unit, to which an AC voltage having a relatively low peak or a static voltage is applied to converge R, G, and B electron beams into one point, even when the electron beams deviate to the corner of a screen. Asymmetrical enlargement portions are included in the rims of each of the R and B electron beam apertures.

    摘要: A color CRT is driven by focusing and accelerating an electron beam emitted from a cathode by forming electron lenses including a quadrupole lens by applying a predetermined voltage to the cathode of an electron gun installed in a neck portion of a funnel and each of electrodes, focusing the electron beam on a fluorescent film by applying a voltage having a horizontal dynamic waveform having a ratio of slopes of 6.85 or more between a unilateral area of 90% and a unilateral area of 50% of a raster area to which a video signal of an image is applied, to at least one of the electrodes forming the quadrupole lens, synchronized with a horizontal deflection signal of a deflection yoke installed at a cone portion of the funnel, in order to deflect an electron beam emitted from the electron gun and scan the deflected electron beam onto the fluorescent film of a panel sealed to the funnel, and forming an image by having the deflected electron beam land on the fluorescent film and excite the fluorescent film. Thus, resolution of the overall screen is increased.
