The Liquid Crystal Display (LCD) driver module
generates the timing control to drive a static or
multiplexed LCD panel. In the PIC16(L)F1933 device,
the module drives the panels of up to four commons
and up to 24 segments. The LCD module 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 common pins:
• Segment pins up to:
• Static, 1/2 or 1/3 LCD Bias

2:
These are not directly connected to the I/O pads, but may be tri-stated, depending on the configuration of
the LCD module.
COM3 and SEG15 share the same physical pin on the PIC16(L)F1933, therefore SEG15 is not available
when using 1/4 multiplex displays.
