Power supply circuit
This is the low power consumption type power supply circuit for generating the voltages
necessary for driving LCD devices, and consists of voltage multiplier circuits, voltage adjustment
circuits, and voltage follower circuits. In the power supply circuit, it is possible to control the
ON/OFF of each of the circuits of the voltage multiplier, voltage adjustment circuits, and voltage
follower circuits using the power control set command. As a result, it is also possible to use parts
of the functions of both the external power supply and the internal power supply. Table 7 shows
the functions controlled by the 3-bit data of the power control set command and Table 8 shows
a sample combination.
