ABSTRACT:
A method for driving a multiplexed LCD panel (38). An LCD controller (20) controls the LCD panel (38) and provides a low power mode which refreshes a subset of the display panel (40) sequentially while refreshing the rest of the panel (38) in parallel. By resolving the panel into these portions, the present invention reduces the power consumption of an LCD module. Display information is stored in a memory (12) and provided to the controller (38) which drives the LCD panel (38). A reset signal eliminates fetching and clocking of zeroes for common areas in the display. One embodiment bit fills to provide a two tone display in low power mode.
