POWER SUPPLY CIRCUITS
The Power Supply circuits generate the voltage levels necessary to drive liquid crystal driver circuits with low power
consumption and the fewest components. There are voltage converter circuits, voltage regulator circuits, and
voltage follower circuits. They are valid only in master operation and controlled by power control instruction. For
details, refers to "Instruction Description". Table 13 shows the referenced combinations in using power supply
circuits.
