Abstract
An adaptive feedback control method of a field sequential color display includes: a rearrangement step of converting gray-scale values of a three primary color field of an input image into gray-scale values of a new three primary color field and a dominated color field; a sampling step of performing a pixel sampling on a resolution of the input image in a sampling interval; a feedback control step of performing a pixel by pixel sum operation for each separated color on a color break-up value and a color value of the input image in a Lu'v′ color space to obtain a color difference sum, and performing a feedback control at a bit precision on the color difference sum; and a liquid crystal/backlight synchronization step of synchronizing a liquid crystal signal and a backlight grayscale value of the input image according to the minimum color difference sum.
