Freescale Semiconductor
The voltage waveform across the "f" segment of the LCD (between BP1
and FP0) is illustrated in
voltage peaks reach the LCD-ON voltage, V
will be ON.
The voltage waveform across the "e" segment of the LCD (between BP2
and FP0) is illustrated in
voltage peaks do not reach the LCD-ON voltage, V
segment will be OFF.
