Abstract:
1. An adaptive feedback control method of a field sequential color (FSC) display, comprising: a rearrangement step, wherein gray-scale values of a three primary color field of an input image are converted into gray-scale values of a new three primary color field and a dominated color field (D-field); a sampling step, wherein a pixel sampling is performed on a resolution of the input image in a sampling interval; a feedback control step, wherein a pixel by pixel sum operation is performed for each separated color on a color break-up (CBU) color value and a color value of the input image in a Lu′v′ color space to obtain a color difference sum, and a feedback control is performed at a bit precision on the color difference sum, thereby obtaining a minimum color difference sum; and a liquid crystal/backlight synchronization step, wherein a liquid crystal signal (LC signal) and a backlight grayscale value of the input image are synchronized according to the minimum color difference sum; wherein the color difference sum ΔE Lu′v′
