评价彩色LCD图像质量的新方法

New Method for Evaluating Image Quality of Color LCD

通过测量调制传递函数评价彩色LCD的图像质量是一种新方法。测量系统由线性电荷耦合元件组成。白点的扫描宽度由LCD的特性确定。实验结果表明,调制传递函数测量方法对于彩色LCD图像质量的评价是非常有用的。

A new method for evaluating image quality of color LCD by measuring modulation transfer func tion is presented.The measurement system is constructed with a linear charge coupled device.The scanning width of a white dot is determined by considering the characteristics of LCDs.The experimental results show that the modulation transfer function measuring method is very useful to evaluating the image quality of color LCDs.
