LCD bias ratio can be selected by LCD bias set command
which is 1/6 bias or 1/8 bias for S1D15A06 series.
On-chip Power Supply Turn Off Sequence
Before turning the built-in power supply off, to discharge
the remaining electric charge of LCD panel and power
supply PIN etc., it is recommended to turn on the power

Command address
From expressions C-2 and C-3, R1 = 1.4M /
8.11=173k .
And, you can select V = 5V when R2 = R2 through the
following computation:
R2 = 137@ and R3 = 1.09 M are derived from expres-
sions C-2, C-3 and C-4.
