Abstract:
1. A method for driving a liquid crystal display (LCD) monitor for displaying a plurality of frame data during a plurality of frame durations comprising: providing a common-voltage signal having a level conversion during each frame duration; dividing each frame duration into a first sub-frame duration and a second sub-frame duration according to a position having the level conversion of the common-voltage signal; driving a first set of pixel units during the first sub-frame duration according to a level of the common-voltage signal within the first sub-frame duration; driving a second set of pixel units during the second sub-frame duration according to a level of the common-voltage signal within the second sub-frame duration, comparing brightness generated by the first set of pixel units and the second set of pixel units; and adjusting the level of the common-voltage signal during only the second sub-frame duration of each frame duration according to a brightness difference between the first set of pixel units and the second set of pixel units.
