13.3.5
When a large LCD panel is driven, or if segments are expanded externally, the built-in power
supply capacity may be insufficient, making it necessary to lower the power supply impedance.
One method, shown in figure 13.12, is to connect a bypass capacitor of around 0.1 µF to 0.3 µF to
pins V
voltage divider externally.
