摘要:
A new driving technique is disclosed for a liquid crystal display panel for displaying at least two rows of characters and a cursor line while scanning scanning lines of the panel, which technique can decrease the number of scanning lines and increases the above defined voltage margin by scanning the scanning lines each two rows at a time in a line sequential scanning fashion and skipping the scanning of a cursor line electrode in a row where a display of the cursor line is unrequired, thus ensuring good contrast and viewing angle characteristics of the panels.
