n-line reversal alternating current drive waveforms (Example of n=5: when the line reversal
register is set to 4)
Common Output State Selection Circuit
The S1D15710 series can set the scanning direction of
the COM output using the common output state selection
command (see Figure 6). Therefore the IC assignment
restrictions at LCD module assembly are reduced.

Liquid Crystal Drive Circuit
This liquid crystal drive circuit is 289 sets of mutiplexers
that generate quadruple levels for liquid crystal drive. It
outputs the liquid crystal drive voltage that corresponds
to the combinations of the display data, COM scanning
signal, and FR signal.
Figure 6 shows examples of the SEG and COM output
waveforms.
