摘要： A color picture tube in which an electron gun emits three electron beams arranged in line, in which the diameter of the spot (26) at the center of the screen in the in-line direction is smaller than that in the direction perpendicular to the in-line direction when the spot is in a just-focused state. Therefore the shape of the spot (27) at the periphery of the screen is generally a true circle. As a result, the resolution at the periphery of the phosphor screen is improved, and the more is suppressed.

摘要： It is intended to improve the focus characteristic while not requiring an increased focus voltage and hence enabling use of a general-purpose flyback transformer. A focus electrode for formation of a final-stage main lens that focuses electron beams generated by a beam generating section of an electron gun onto a phosphor screen is divided into a plurality of electrode members. The divisional electrode members form plural stages of electron lenses whose focusing power varies in synchronism with the deflection amount of the electron beams. A relationship 31nullLnull4.7Vnull9.3null43 is established, where V (mm) is the vertical diameter of an aperture formed in an end portion of the focus electrode that is opposed to an anode electrode and L is the total length (mm) of the focus electrode in the tube axial direction.

摘要： A color display device (19) is disclosed with an improved focus performance. In present-day color display tubes with DAF, the electron gun is provided with a second focusing electrode (25) driven with a dynamic voltage which is varied synchronously with the deflection field. The dynamic quadrupole lens formed between the first focusing electrode (23) and the second focusing electrode (25) is designed in such a way that the horizontal lens action, which arises when the voltage on the second focusing electrode is increased, should be compensated by the main lens which becomes weaker when the voltage on the second focusing electrode (25) is increased. In practice, it is not possible to achieve this in the required range of the dynamic voltage on the second focusing electrode (25), leading to a deterioration of the focus performance of the color display device (19). This problem is solved by the present invention. By applying a dynamic voltage to the first focusing electrode (23), it becomes possible to focus the electron spots on the display window (3) in the horizontal and vertical directions, resulting in an optimally focused picture.

摘要： A color picture tube apparatus comprises auxiliary electrodes provided between first and second focusing electrodes, a nonaxisymmetric electrostatic lens is generated between the auxiliary electrodes and a focusing lens is generated between the first focusing electrode and the auxiliary electrode. A dynamic voltage V.sub.d is applied to the first and second focusing electrodes. Consequently, the effect of compensating the astigmatism of the electron beam caused by the deflection magnetic field and the defocus of the electron beam can be increased, the dynamic voltage can be decreased, and as a result, the cost of the circuit can be reduced. As the focusing function of the additional focusing lens is weakened and the electron beam trajectory is expanded, the magnification of the lens both at the center and the periphery of the screen can be equalized substantially and the uniformity of the focus of the electron beam between that at the center of the screen and that at the periphery of the screen becomes high.
