A method for driving an active matrix liquid crystal display (AMLCD) to perform partial display area displaying on a portion of a display area thereof is disclosed. The method includes: using a common electrode voltage for line alternate-driving in a first write period of a partial display area, and for frame alternate-driving in at least a portion of a second write period outside of the partial display area; and in a frame alternate-driving period of the second write period outside of the partial display area, controlling the common electrode voltage to adjust one of two voltage durations of the common electrode voltage which are respectively before and after the first write period of the partial display area and in which the common electrode voltage are of the same polarity, to make the two voltage durations have equal lengths.
