Partial Display Function
The partial display function allows the R61509V to drive lines selectively to display partial images by
setting partial display control registers. The lines not used for displaying partial images are driven at non-
lit display level to reduce power consumption.
The power efficiency can be enhanced in combination with 8-color display mode. Check the display
quality when using low power consumption functions.
