<Waiting (approximately 100ms)>
Wait until the power supply voltage has stabilized.
Enter the command of power supply control first, and then wait at least 100ms before entering the display ON
command when the built-in power supply circuit operates.
If you do not wait, an unexpected display may appear on the liquid crystal panel.

*1: When the IC is in SLEEP IN state, the liquid crystal drive power supply, the boosting power output, and
GND pin are connected together, therefore, the SLEEP OUT command must be entered to cancel the SLEEP
state prior to turning on the built-in circuit.
(Note) If changes are unnecessary after resetting, command input is unnecessary.
