摘要： A cathode ray tube includes a vacuum envelope having a substantially rectangular panel, a cylindrical neck, and a funnel connecting the panel and the neck. A phosphor screen arranged on the inner surface of the panel generates luminescence upon impingement of electron beams, which are generated by an electron gun assembly disposed in the neck. In order to create a image visible through the panel, a deflection yoke is mounted on the outer surface of the funnel to generate a magnetic field in the funnel, deflect the electron beams, and thereby scan the phosphor screen. According to the present invention, the portion of the funnel over which the deflection yoke is mounted is formed such that the power required to generate a deflection field capable of scanning substantially the entire phosphor screen may be reduced. To this end, the funnel is formed over a predetermined range along a first axis coincident with the axis of symmetry of the cylindrical neck such that at least one cross section of the inner and outer funnel perpendicular to the first axis has a non-circular shape and a maximum diameter along a direction other than those of the major and minor axes of the substantially rectangular panel. Moreover, within this predetermined range, the point on the funnel's cross section that is furthest from the first axis is not located along the direction of the panel's diagonal axis.

摘要： First and second index signal phosphor layers are formed on a phosphor screen that is formed on the inner surface of a face plate. A rear plate is provided with first and second light sensing units for detecting signal lights from the first and second index signal phosphor layers, respectively. Each first light sensing unit includes a first light collecting plate, which radiates absorbing light having a radiation peak wavelength substantially equal to or shorter than the radiation wavelength of each first index signal phosphor layer. Each second light sensing unit includes a second light collecting plate, which radiates absorbing light having a radiation peak wavelength substantially equal to or shorter than the radiation wavelength of each second index signal phosphor layer. Arranged between each second collecting plate and the rear plate is a filter, which transmits the index signal light from the second index signal phosphor layer and shades the index signal light from the first index signal phosphor layer.

摘要： A color cathode ray tube apparatus is provided with an electron gun which has a common large-aperture electron lens on which three electron beams are incident. Since the electron gun has individual electron lenses for individual electron beams, the electron beams can be properly converged and focused on a screen. Thus, the apparatus enjoys a satisfactory picture characteristic.

摘要： In an electron gun assembly for a cathode ray tube, the center and side electron beams emitted from cathodes are incident on a main electric lens. The center and side electron beams are focused, respectively. The side beams are over-converged and directed to an over-converged point by the main electric lens. The side beams emerged from the main electric lens are deflected and corrected by a divergent lens so that the center and side beams are converged on a proper converged point between the screen and the over-converged point.
