5 FUNCTIONAL SPECIFICATION
5.1 COMMANDS
5.2 POWER UP/DOWN SEQUENCE
To protect panel and extend the panel lifetime, the driver IC power up/down routine should
include a delay period between high voltage and low voltage power sources during turn
on/off. It gives the panel enough time to complete the action of charge and discharge
before/after the operation.
