R0
Display OFF. Internal operation stops.
Specify power ON mode 1 (master IC only).
R0
Display OFF.
Internal operation starts.
Wait time 1
Wait for 120 to 150 ms or more from when the internal
operation starts until the LCD turns ON
Note
.
Change the operation mode of the operation amplifier to
“normal mode” (master IC only).
Segment output driving capability setting: x8
Common output driving capability setting: x16
Voltage follower bias current: x2
Note
The wait times1, 2 vary depending on the characteristics of the LCD panel and the capacitance of the
boosting or smoothing capacitor. It is recommended to determine this value after thorough evaluation with
the actual system (refer to
8.5 Flow of V
OUT
and V
LCD
Voltages from Power ON to Power OFF
).
