摘要: An electron gun for a color CRT includes a triode including cathodes for emitting electron beams, a control electrode, and a screen electrode, at least two focusing electrodes on the same axis of the triode portion for forming a quadrupole lens, and a final focusing electrode forming a large diameter lens with the focusing electrodes and through which three electron beams commonly pass. The electron gun includes a correction unit producing a correction force acting on the three electron beams and that is larger for two side electron beams than for a central electron beam of the three electron beams when a dynamic voltage, synchronized with a deflection signal, is applied to at least one of the focusing electrodes for forming the quadrupole lens.

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 electrode unit of an electron gun for a cathode ray tube including an outer rim electrode having a large-diameter electron beam passing hole through which three electron beams pass, and an inner electrode installed within the outer rim electrode and having a central electron beam passing hole disposed at its center and side electron beam passing holes disposed at opposite sides of the central electron beam passing hole. The side electron beam passing holes each have first and second curved sides along the sides closest to the central electron beam passing hole and opposite those sides, and linear portions connecting the first and second curved portions. The vertical and horizontal dimensions of the side electron beam passing holes are equal to each other.
