The Theoretial Evidence of Horizontal Pincushion Correction of New Type Large Screen Colour Television
摘要/Abstract
摘要：
详细地论述了新型大屏幕彩电采用改变激励电压方法进行水平枕形校正的基本电路模型的工作原理, 论证了校正后的行逆程峰值电压不随校正信号的变化而变化, 解决了用传统方法校正存在的弊端
Abstract：
Using the method of changing the exciting voltage of the new type large screen colour TV, the operating principle of basic circuit model of the correction for horizontal pincushion distortion is described in detail. It is demonstrated that the horizontal reverse peak voltage corrected doesn't change with the size of correction signal, and existing problem in traditional correctional method is solved.
