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. VON(RMS) = 0.79 VDD

2. VOFF(RMS) = 0.35 VDD.
