Note: 1. The above figure shows how a liquid crystal panel can be arranged into a 1-line/12-character display while operating the HD66730 in
2-line/6-character display mode. Although the duty ratio becomes high, extension drivers will not be needed. COM13 for spaces
between display lines will not be needed.
