The Liquid Crystal Display (LCD) driver module
generates the timing control to drive a static or
multiplexed LCD panel. In the 80-pin devices
(PIC18F8XK90), the module drives the panels of up to
four commons and up to 48 segments and in the 64-pin
devices (PIC18F6XK90), the module drives the panels
of up to four commons and up to 33 segments. It also
provides control of the LCD pixel data.

The LCD driver module supports:
• Direct driving of LCD panel
• Three LCD clock sources with selectable prescaler
• Up to four commons:
• Up to 48 (in 80-pin devices), 32 (in 64-pin
• Static, 1/2 or 1/3 LCD bias
• Internal resistors for bias voltage generation
• Software contrast control for LCD using the
A simplified block diagram of the module is shown in
