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 emplo- ying 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.
