Abstract LCD motion blur is a well‐known phenomenon and several approaches have been developed to address it. This includes very high performing approaches based on Motion‐Compensated Frame‐Rate‐Conversion (MC‐FRC) and very low cost approaches based on impulsive driving. Impulsive driving schemes are attractive because of their low cost but suffer from two significant issues — loss of luminance and large area flicker. We propose a new impulsive driving approach using Motion‐Adaptive Alternate Gamma Driving (MA‐AGD) which removes motion blur and preserves the original luminance level without causing large area flicker.
