(6) LCD drive circuit
The LCD drive circuit is configured of 4 common drivers and 18 segment drivers. When oscillation begins, any effec-
tive common output automatically outputs a selective waveform, while the others output non-selective waveforms.
Segment output automatically outputs drive waveforms, based on the display data and common counter. The com-
mon and segment output waveforms are shown in the following examples.
