摘要： The present invention provides a high-resolution color picture tube device with a decreased beam spot diameter. The color picture tube device has an electron gun (23) including cathodes (1), a control electrode (2), an accelerating electrode (3), a G3 electrode (4), a first focusing electrode (5), a second focusing electrode (6), and a final accelerating electrode (7) that are arranged in this order. A voltage applied to the G3 electrode (4) is obtained by dividing with a resistor (10) a voltage applied to the final accelerating electrode (7), and when an electron beam is a non-deflection state, a relationship represented as Va > Vg3 > Vfoc2 is satisfied where Va, Vg3, and Vfoc2 denote voltages respectively applied to the final accelerating electrode (7), the G3 electrode (4) and the second focusing electrode (6). Thereby, the G3 electrode (4) is applied with a high voltage independently for forming a prefocus lens.

摘要： A CRT device with an electron gun provided therein includes control means for controlling voltages applied to a cathode and a control electrode constituting the electron gun. The control means exerts control on each electrode voltage so that the difference between the cutoff voltage of the cathode and the voltage of the control electrode is greater when the luminance level of a luminance signal separated from picture signal is higher, thereby minimizing a spot diameter.

摘要： A set of three cathodes, a control electrode, an accelerating electrode, a first focus electrode, a second focus electrode, a third focus electrode, a fourth focus electrode, a final accelerating electrode and a shield cup electrode are provided successively in an electron beam travelling direction. The shield cup electrode has a pair of screen-shaped electrodes that sandwich electron-beam through-holes in a vertical direction. A quadrupole lens that has a horizontal convergent action and a vertical divergent action is generated by an electrical potential difference between the screen-shaped electrodes and the final accelerating electrode. Accordingly, even if vertical and horizontal convergence power difference in a main lens formed by the fourth focus electrode and the final accelerating electrode is not large, a composite lens formed through a combination of the quadrupole lens and the main lens has strong horizontal convergence power and weak vertical convergence power.

摘要： A color picture tube apparatus having an inline electron gun that allows technology for applying a dynamic voltage to an OLF lens to be implemented, while avoiding design difficulties. Eave-shaped electrode plates are attached, parallel with each other in a horizontal scan direction, to a field-correction electrode plate, which is a horizontally long, flatten plate in which three holes are provided, and whose shape is similar to that of an aperture in a circumferential electrode. This structure allows quadrupole lenses to be formed as auxiliary lenses having strong focusing action horizontally and divergent action vertically, and thus an HV differential can be increased. As a result, it is possible to reduce the dynamic voltage without any of the design difficulties accompanying the prior art, in which eave-shaped electrode plates are not provided.
摘要翻译：一种具有直列式电子枪的彩色显像管装置，其允许实施向OLF透镜施加动态电压的技术，同时避免设计困难。檐形电极板在水平扫描方向上彼此平行地连接到场校正电极板，该场校正电极板是设置有三个孔的水平长且平坦的板，并且其形状类似于圆周电极中的孔。这种结构允许四极透镜形成为具有强烈水平聚焦作用和垂直发散作用的辅助透镜，因此可以增加HV差分。结果，可以减小动态电压而没有伴随现有技术的设计困难，其中不提供檐形电极板。
