Appeal No. 96-2025
Application 07/860,254
through 6, 8 and 9 also recite similar language requiring the
production of a symmetrical voltage waveform as shown in
Figure 6 (3) which is then applied to the pixels. In
reviewing claim 7, we note that Appellants claim "a data
electrode driving circuit for applying a first modulated
voltage with a time duration corresponding to a logical value
of a binary code ... in a term corresponding to one electrode
of the adjacent scanning side electrode pair, inverting the
logical value of the binary code ... and for applying the
binary complement as a second modulated voltage in a term
corresponding to the other electrode of the adjacent scanning
side electrode pairs, to the data side electrodes." Thus,
claim 7 results in the production of a symmetrical voltage
waveform as shown in Figure 6 (3) which is then applied to the
pixels.
Upon a careful review of Inada, we find that the
reference fails to teach the production of a symmetrical
voltage waveform shown in Figure 6 (3) by inverting the binary
code signal so the gradation display data and its binary
complement are utilized
