It is important to match the module properties to those of the driver in order to achieve
optimum performance.
The PCF2119x contains 18 row and 80 column drivers, which drive the appropriate LCD
bias voltages in sequence to the display in accordance with the data to be displayed. R17
and R18 drive the icon rows. Unused outputs should be left open.
The bias voltages and the timing are selected automatically when the number of lines in
the display is selected.
