Abstract
The present invention relates to a driving method of a cholesteric liquid crystal display. It includes the steps in the following: driving each scan line by a dynamic driving scheme (DDS) including an Evolution phase; refreshing a frame of the cholesteric liquid crystal display by a full refresh mode, each scan line driven N times during the Evolution phase in the full refresh mode; and refreshing a part of the frame by a partial-refresh mode, each scan line driven M times in the Evolution phase in the partial-refresh mode, wherein M is greater than N.
