15.3
The LCD driver module is capable of generating the
required bias voltages for LCD operation with a mini-
mum of external components. This includes the ability
to generate the different voltage levels required by the
different bias types required by the LCD. The driver
module can also provide bias voltages both above and
below microcontroller V
on-chip LCD voltage regulator.
15.3.1
PIC18F85J90 family devices support three bias types
based on the waveforms generated to control
segments and commons:
• Static (two discrete levels)
• 1/2 Bias (three discrete levels
• 1/3 Bias (four discrete levels)
The use of different waveforms in driving the LCD is dis-
cussed in more detail in Section 15.8 “LCD Waveform
Generation”.

15.3.2
The purpose of the LCD regulator is to provide proper
bias voltage and good contrast for the LCD, regardless
of V
internal voltage reference. The regulator can be config-
ured by using external components to boost bias
voltage above V
constant voltage below V
selectively disabled to allow bias voltages to be
generated by an external resistor network.
The LCD regulator is controlled through the LCDREG
register (Register 15-5). It is enabled or disabled using
the CKSEL1:CKSEL0 bits, while the charge pump can
be selectively enabled using the CPEN bit. When the
regulator is enabled, the MODE13 bit is used to select
the bias type. The peak LCD bias voltage, measured as
a difference between the potentials of LCDBIAS3 and
LCDBIAS0, is configured with the BIAS bits.
