Note *2 The following relations between elements should be maintained:
VDD≥V1>V3>V4>VEE, VDD-V3≤7V, V4-VEE≤7V
*3 When the power is turned on, either the logic system power must be turned on before the LCD drive system
power or else they must both be turned on at the same time. When the power is turned off, either the LCD drive
system power must be turned off before the logic system power, or else both must be turned off at the same
time.
