LightBoost HOWTO | Blur Busters (http://www.blurbusters.com/zero-motion-blur/lightboost/) is an interesting article on technologies used to avoid motion blur on LCD monitors.
LightBoost is a programmable strobe backlight. The backlight is turned off while waiting for LCD to finish pixel transitions (unseen by human eyes), and the backlight is strobed only on fully-refreshed LCD frames (seen by human eyes). The strobes can be shorter than the panel’s pixel transitions, bypassing the pixel transition speed limit!
The aim is to get CRT-quality perfectly sharp fast motion on LCD.
