(28) PARTIAL DISPLAY FUNCTION
HM17CM256 can realize the partial display at graphic display area on LCD panel.
Partial display is used with lower duty than normal state at driving.
And so, HM17CM256 can drive the LCD panel with lower bias ratio, lower boosting times and
lower LCD driving voltages, and that can drive the LCD panel with lower power consumption.
This function is suitable for calendar or clock display at mobile information apparatus.
