大屏幕彩色投影电视用偏转系统的设计

Scanning yoke for Large Screen Colour Projection

在大屏幕彩色投影电视中,为了使三基色象在屏上会聚,必须对梯形失真和非线性失其进行调节。这些调节可以用改进偏转线圈绕组结构的方法来达到。本文介绍了偏转绕组结构的设计。对设计中遇到的一些问题作了较详细的讨论。

In the color projection TV set, adjustments must be made for Trapezoidal and nonlinearity distortions in order to Converge the three primany images on the screen. These adjustments can be made by varying the configuration of deflection windings. In the paper, the design of deflection winding configuration is described. Some problems in design are discussed in detail.
