Section 17 LCD Controller/Driver
17.4.6
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 V1 to V3, as shown in figure 17.12, or by adding a split-resistance
externally.
