Claim:
A method for displaying a color image, comprising: in a first sub-time frame, emitting light with a first color for a first duration; in a first input period of the first sub-time frame, inputting a first signal to determine an extent of rotation of a corresponding liquid crystal, wherein the first input period precedes the first duration and does not overlap with the first duration; after the first input period and before the first duration, rotating the corresponding liquid crystal according to the first signal in a first rotating period of the liquid crystal; and in a second sub-time frame, emitting light with a second color for a second duration; wherein the first sub-time frame does not overlap with the second sub-time frame, and the first duration is different from the second duration; wherein a middle point of the first duration is a middle point of a period from an end of the first rotating period of the liquid crystal to a beginning of the second sub-time frame.
