摘要

为了研究显示器中的运动图像模糊问题，我们推导出了一个简单的方程，将运动图像响应时间与液晶或者有机发光二极管的响应时间以及帧率结合起来。从方程中可以看出，减小运动图像响应时间有3种方法：（1）减小液晶响应时间|（2）提高帧率|（3）选取合适的背光开关占空比。在显示器帧率为120 Hz时，如果液晶的响应时间小于2 ms，那么液晶显示器的运动图像响应时间与有机发光二极管显示器相当。液晶的响应时间可以通过两种方法提高：（1）采用超低黏性系数的液晶材料|（2）开发快速响应液晶显示器工作模式。同时，为了使液晶显示器达到像阴极射线显像管一样快速的运动图像响应时间（ < 1.5 ms），我们可以增加帧率或者减小背光开关占空比。

Abstract

In order to analyze the image blur of displays

a simple equation to correlate the motion picture response time (MPRT) with LC response time and TFT frame rate is established. Three effective approaches to reduce MPRT are:(1) fast LC response time; (2) high frame rate

and (3) appropriate backlight duty ratio. At 120 Hz frame rate

if the LC's response time is less than 2 ms

then its MPRT would be comparable to that of OLED. LC response time can be greatly improved by employing an ultra-low viscosity LC and developing fast-response LCD modes. To achieve CRT-like MPRT (less than 1.5 ms)

we could increase the frame rate or decrease the duty ratio.
