2. When the built-in power is not being used immediately after turning on the power:

* The target time of 5ms will result to vary depending on the panel characteristics and the capacitance of the smoothing

capacitor. Therefore, we suggest you to conduct an operation check using the actual equipment.

Command description; Power saver START (multiple commands)

Turn ON the VDD-VSS power keeping the

/RES pin = “L”.

When the power is stabilized

Release the reset state. (/RES pin = “H”)
