When multiplexing drive is not used, or during the standby or sleep mode, all the above common and
segment signal drivers output the GND level, halting the display.
Booster (DC-DC Converter)
The booster generates triple, quadruple, or five-times voltage input to the Vci pin. With this, both the
internal logic units and LCD drivers can be controlled with a single power supply. Boost output level from
triple to five-times boost can be selected by software. For details, see the Power Supply for Liquid Crystal
Display Drive section.
V-Pin Voltage Follower
A voltage follower for each voltage level (V1 to V5) reduces current consumption by the LCD drive power
supply circuit. No external resistors are required because of the internal bleeder-resistor, which generates
different levels of LCD drive voltage. This internal bleeder-resistor can be software-specified from 1/4 bias
to 1/10 bias, according to the liquid crystal display drive duty value. The voltage followers can be turned
off while multiplexing drive is not being used. For details, see the Power Supply for Liquid Crystal Display
Drive section.
Contrast Adjuster
The contrast adjuster can be used to adjust LCD contrast in 64 steps by varying the LCD drive voltage by
software. This can be used to select an appropriate LCD brightness or to compensate for temperature.
