LCD drive mode waveforms
The static LCD drive mode is used when a single backplane is provided in the LCD. Backplane and segment drive
waveforms for this mode are shown in Fig.4.
When two backplanes are provided in the LCD the 1 : 2 multiplex drive mode applies. The PCF8566 allows use of

or

bias in this mode as shown in Figs 5 and 6.
The backplane and segment drive waveforms for the 1 : 3 multiplex drive mode (three LCD backplanes) and for the 1 : 4
multiplex drive mode (four LCD backplanes) are shown in Figs 7 and 8 respectively.
