8.12 Set COM Output Scan Direction
This command sets the scan direction of the COM output allowing layout flexibility in LCD
module assembly.
8.13 Set Power Control Register
This command turns on/off the various power circuits associated with the chip. There are three
power relating sub-circuits could be turned on/off by this command.
Internal voltage booster is used to generate the highest positive voltage supply internally from
the voltage input (V
CI
-V
SS
).
Internal regulator is used to generate the LCD driving voltage.
Output op-amp buffer is the internal divider for dividing the different voltage levels (V
L2
, V
L3
, V
L4
,
V
L5
) from the internal regulator output, V
out
. External voltage sources should be fed into this
driver if this circuit is turned off.
8.14 Set Internal Regulator Resistors Ratio
This command is to enable any one of the eight internal resistor (IRS) settings for different
regulator gains when using internal regulator resistor network. The Contrast Control Voltage
Range curves is referred to the following formula:
