strength and power consumption. Users also can disable the internal bias circuit and use the external
resistor bias circuit by setting the mask option MO_LCDBE to ‘0’. The LVG pin can be connected to
ground directly or connecting to a variable resistor to fine-tune the LCD contrast as below diagram
shown.
