新型大屏幕彩电水平枕形校正的理论依据

The Theoretial Evidence of HorizontalPincushion Correction of New Type Large Screen Colour Television

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。

Using the m ethod ofchanging the exciting voltage of the new type large screen colour TV,the operating principle of basic circuit m odelof the correction for horizontal pincushion distortion is described in detail. It is dem onstrated that the horizontal reverse peak voltage corrected doesn't change w ith the size of correction signal,and existing problem in traditionalcorrectionalm ethod is solved.
