Liquid Crystal Display Driver (LCD)
The voltage waveform across the "f" segment of the LCD (between BP1
and FP0) is illustrated in Figure 16-14. As shown in the waveform, the
voltage peaks reach the LCD-ON voltage, VLCD, therefore, the segment
will be ON.

The voltage waveform across the "e" segment of the LCD (between BP2
and FP0) is illustrated in Figure 16-15. As shown in the waveform, the
voltage peaks do not reach the LCD-ON voltage, VLCD, therefore, the
segment will be OFF.
