采用DBS-Ⅱ这种新方法,校正电子束光点的偏转畸变,研制出一种高分辨率一字型彩色CRT。在聚焦电极的漂移空间中,安装一平板电极,利用它产生的四极电场使DBS-Ⅱ工作。DBS-Ⅱ系统工作时的一个优点是只使用一种信号。为了在整个荧光屏上得到轮廓分明的束斑和消除外层束的动态会
DBS-Ⅱ using this new method to correct the electron beam deflection of the spot, developed a high-resolution monolithic color CRT. In the drift space of the focusing electrode, a plate electrode is mounted and the DBS-II is operated using the quadrupole field generated by it. One advantage of working with a DBS-II system is that it uses only one type of signal. In order to obtain a well-defined beam spot on the entire screen and to eliminate the dynamics of the outer beam
