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.

Backplane and segment drive waveforms for this mode are shown in Figure 5.

V_state1(t) = V_Sn(t) − V_BP0(t).

V_on(RMS)= V_LCD

V_state2(t) = V_Sn+1(t) − V_BP0(t).

V_off(RMS)= 0 V.
