Abstract:
1. A method of reducing motion blur in a liquid crystal cell, the method comprising the steps of: converting a previous picture frame from an RGB color space into a YUV color space; storing a luminance component in the YUV color space related to the previous picture frame; converting a current picture frame from an RGB color space into the YUV color space; determining an overdrive factor based on a difference between a luminance component in the current picture frame in the YUV color space and the stored luminance component; creating a modified luminance component by applying the overdrive factor only to the luminance component of the current picture frame in the YUV color space; and converting the modified luminance component and color components of the current picture frame back into an RGB color space for display in the liquid crystal cell; thereby increasing the transition speed from one luminance level to another.
