| Abstract: | In order to reduce the motion blur of LCDs,various methods have been proposed,such as overdriving,backlight scanning,high frame rate,and so on.How to objectively and correctly evaluate the motion blur degree of LCDs and compare different methods is very important to LCD's development and application.Dynamic modulation transfer function(MTF) is introduced as parameter of motion blur of LCDs.The physical meaning,measurement principle,calculation and particular application of dynamic modulation transfer functi... |
