ABSTRACT:
A reduced-power method of updating an LCD display. LCD displays are refreshed line by line. Lines of the display which do not need to be updated, i.e. which are blank, are refreshed with less power than lines which require updating. This is achieved by latching display data to the blank lines for only a very short period of time.
