7.8.4 Bias Divider
If the output op-amp buffer option in Set Power Control Register command is enabled,
this circuit block will divide the regulator output (V

) to give the LCD driving levels (V
L2
-
V
L5
).
A low power consumption circuit design in this bias divider saves most of the display
current comparing to traditional design.
7.8.5 Bias Ratio Selection circuitry
Software control of 1/5 to 1/12 bias ratio is to match the characteristic of LCD panel.
7.8.6 Self adjust temperature compensation circuitry
Provide 8 different compensation grade selections to satisfy the various liquid crystal
temperature grades. The grading can be selected by software control. Default temperature
coefficient (TC) value is -0.125%/
C.
