2. When the built-in power is not being used immediately after turning on the power:
Turn ON the VDD-VSS power keeping the
/RES pin = “L”.
When the power is stabilized
Release the reset state. (/RES pin = “H”)
Initialized state (Default) *1
Power saver START
(multiple commands) *8
Function setup by command input (User
setup)
(11) LCD bias setting *2
(8) ADC selection *3
(15) Common output state selection *4
Arrange to start the
power saver within
5ms after releasing the
reset state. (In case of
other models) execute
the procedures from
turning on the power
to setting the power
control in 5ms.
Function setup by command input (User
setup)
(17) Setting the built-in resistance radio
for regulation of the V5 voltage *5
(18) Electronic volume control *6
Power saver OFF *8
Function setup by command input (User
setup)
(16) Power control setting *7
Arrange to start power
control setting within
5ms after turning OFF
the power saver.
This concludes the initialization
* 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.
