4-digit duplex LCD car clock
PCF1175C
FUNCTIONAL DESCRIPTION AND TESTING
Outputs
The circuit outputs 1 : 2 multiplexed data (duplex) to the
LCD. Generation of BP1 and BP2 (three-level backplane
signals) and the output signals are shown in Fig.4.
The average voltages across the segments are:
1.
V
ON(RMS)
= 0.79 V

2.
V
OFF(RMS)
= 0.35 V
