Methods and systems for processing image data for display on LC displays

A method for processing image data in a liquid crystal display (LCD) overdrive system, said method comprising:

• receiving original image data for display on an LCD display;
• sending said original image data to an overdrive calculation module for calculation of overdrive image data;
• sending said overdrive image data to a prediction module for calculation of predicted image data;
• reducing a bit depth of said predicted image data using a non-linear mapping function thereby creating reduced image data;
• converting said reduced image data from a luminance-integrated color space to a luminance-segregated color space comprising a luminance channel and at least one chrominance channel;
• spatially down-sampling said at least one chrominance channel;
• and
• compressing said reduced, converted and down-sampled image using spatial redundancy methods, thereby creating compressed image data;
• storing said compressed image data in a buffer;
• decompressing said compressed image data after a delay, thereby creating decompressed, delayed image data;
• and
• using said decompressed, delayed image data for overdrive-related calculations for a subsequent image frame.
