Universal LCD driver for low multiplex rates
7.4 LCD drive mode waveforms
7.4.1 Static drive mode
The static LCD drive mode is used when a single backplane is provided in the LCD. The
backplane (BP0) and segment drive (Sn) waveforms for this mode are shown in Figure 4.

Vstate1(t) = VSn(t) − VBP0(t).
Von(RMS) = VLCD.
Vstate2(t) = V(Sn+1)(t) − VBP0(t).
Voff(RMS) = 0 V.
