after image

At present,the response speed of liquid crystal display has been significantly improved,but the motion blur,caused by moving objects blur or smear phenomenon,is always the prominent problem of liquid crystal display technology when showing the dynamic image of the high-speed movement of objects,so research of image sticking is very important to theory and practical production of LCD.

分析了液晶显示器在实际生产中时常出现的图像残留问题产生的原因,从理论上推导出了上下基板取向层与液晶分子交界面积累的累积电荷在液晶盒中产生的电场强度的定量关系。

Finally, a distinguished remnant thermal image of a room temperature body was obtained.

３７×１０９ｃｍ·Ｈｚ１／２／Ｗ，并最终获得了清晰的室温物体残留热像图。

The relations of field of view,Strehl criterion,resolution limitation,modulatin transfer function(MTF) and remainder aberration to central obscuration are analyzed theoretic and the allowable diameter of reference plate is 0.

理论分析了被测面视场、Strehl判据、分辨本领、调制传递函数MTF以及残余像差和中心遮拦的关系,得到参考面的允许直径0。
