Figure 38 Temperature Compensation Circuit
Instruction bits (BT1/0) can optionally select the boosting multiplying factor of the internal booster.
According to the display status, power consumption can be reduced by changing the LCD drive duty and
the LCD drive bias, and by controlling the boosting multiplying factor for the minimum requirements. For
details, see the Partial-display-on Function section.
Due to the maximum boosting multiplying factor, the following external capacitor needs to be connected.
For example, when the maximum boosting is tripled, the capacitors between C3+ and C3– for quadruple
boosting are not needed, so these pins must be open.
