Table 12 Display bias setting table
Determine the LCD drive bias according to its display duty, and select combination of boosting ratio of
the step-up circuit 2 and bias amplifier ratio so as not to exceed voltage control of Vci2 and VCH. See
the LCD Voltage Generation Circuit regarding how to determine the LCD drive bias, VCH voltage and
contrast adjustment for the following settings.
