Abstract:
1. A liquid crystal display (LCD) drive circuit for scanning at least two adjacent scan lines simultaneously, comprising: a data driver, a scan driver, a divider, a controller, a plurality of data lines and a plurality of scan lines; wherein the scan driver is connected to the plurality of scan lines; the data driver is connected to the plurality of data lines; the divider is configured to divide the scan lines into a plurality of groups each comprising a plurality of scan lines; and the controller is configured to control the scan driver to scan the plurality of groups of scan lines sequentially, wherein the scan driver is controlled to scan at least two adjacent scan lines in each group simultaneously, and scan the remainder of the each group of scan lines sequentially including the last scan line of the at least two adjacent scan lines scanned simultaneously; the controller is further configured to control the scan driver such that the at least two adjacent scan lines scanned simultaneously within a predetermined time interval are different for different image frames, and positions of the at least two adjacent scan lines scanned simultaneously of each group in a current image frame are different from positions of the at least two adjacent scan lines scanned simultaneously of each group in a next image frame following the current image frame, the positions of the at least two adjacent scan lines scanned simultaneously of each group in the next image frame are shifted downwards from those in the current image frame by a number of the at least two adjacent scan lines scanned simultaneously of each group, wherein the predetermined time interval is in units of image frame durations, and a magnitude of the predetermined time interval is equal to the number of scan lines in each group divided by the number of scan lines scanned simultaneously.
