显示器为了减小图像的失真,设有多种失真校正电路,例如:有几何失真校正、S 电容校正、行线性校正、倾斜校正电路等,有些高档显示器还设有地磁校正电路。一、几何失真校正几何失真校正包括:枕形校正、梯形校正、平行四边形校正、左右枕形平衡(弓形)校正、顶角校正、底角校正等。为便于理解,各种失真的图像见图1所示。几何失真校正电路随着行扫描电路和高压产生电路的形
In order to reduce the distortion of the image, the display has a variety of distortion correction circuit, such as: geometric distortion correction, S capacitance correction, line linearity correction, tilt correction circuit, etc., some high-grade display also has a geomagnetic correction circuit. First, the geometric distortion correction Geometric distortion correction include: pincushion correction, trapezoidal correction, parallelogram correction, left and right pillow-shaped balance (bow) correction, apex angle correction, corner correction and so on. For ease of understanding, a variety of distorted images shown in Figure 1. Geometric distortion correction circuit with the line scan circuit and high voltage generating circuit shape
