    • An improved lateral convergence deflection system for a delta-gun shadow mask color CRT (10) includes first, second and third lateral convergence coils (20, 22, 24) mounted on the CRT neck (10) radially outward from the paths of the electron beams (14,16,18) from the three guns. The coils are connected in series electrically, and are of suitable strength and orientation to provide a substantially unidirectional, vertical field in the path of one (e.g., the blue) beam (14), and field nulls in the paths of the other two (e.g. the red and green) beams (16,18). By varying the current passed through the coils by a convergence drive amplifier, the blue beam may be shifted laterally without producing any substantial movement of the other two beams.
    • 用于三角枪阴影彩色CRT(10)的改进的横向会聚偏转系统包括从电子枪的路径径向向外安装在CRT颈部(10)上的第一,第二和第三横向会聚线圈(20,22,24) 来自三支枪的梁(14,16,18)。 线圈串联电连接,并且具有适当的强度和取向以在一个(例如,蓝色)光束(14)的路径中提供基本上单向的垂直场,并且在另一个(例如,蓝色)光束(14)的路径中的场零点 例如红色和绿色)光束(16,18)。 通过通过会聚驱动放大器改变通过线圈的电流,蓝色光束可以横向偏移而不产生其他两个光束的任何实质的移动。
