17.8 Supplying LCD Drive Voltages V
resistance division method, external resistance division method, or internal voltage boosting method.
17.8.1 Internal resistance division method
voltage divider resistors, a LCD drive power supply that meet each bias method listed in Table 17-9 can be generated,
without using external voltage divider resistors.
