13.3.6 Boosting the LCD Drive Power Supply
When a large panel is driven, the on-chip power supply capacity may be insufficient. In this case,
the power supply impedance must be reduced. This can be done by connecting bypass capacitors
of around 0.1 to 0.3 µF to pins V

to V
3
, as shown in figure 13.17, or by adding a split-resistance
externally.
