The row voltages (F) are not necessarily larger then the
column voltages. This depends on the number of rows
which are selected, the multiplexibility and the value of p.
However, the PCF8811 is designed in such a way that the
maximum column voltages are always equal to the row
voltages. In Table 20 the V
LCD
and the different bias levels
are given for the PCF8811. The V
LCD
voltage is defined as:
(2)
Where F is defined in (1)
The bias system settings for different display modes are
given in Table 20. All bias levels can be calculated by
using the third column of Table 19 and the variables given
in Table 20. Programming of the bias levels is not
necessary in the PCF8811. The selection of the
appropriate bias level voltages for each display mode is
done automatically. Only the appropriate V
LCD
voltage
must be programmed according to equations (1) and (2)
for the display modes listed in Table 20.
The variables for calculating V
LCD
, when the icon row is
enabled, are given in Table 21. The icon row can only be
addressed in the extended command set.
The PCF8811 allows the value of p, for certain mux rates,
to be chosen manually.
This is only possible for the mux rates 1 : 64 and 1 : 80.
If other mux rates are chosen the PCF8811 determines
the optimum value of p. By setting the value of p manually
a compromise can be made between contrast and power
consumption with certain liquids for the high mux rates
1 : 64 and 1 : 80. However, care must be taken that the
liquid which is chosen ensures that the row voltages (F)
and the maximum column voltages are equal.
