Appeal No. 1997-0830
Application 08/132,998
Upon our careful review of Yamazaki, we fail to find
that Yamazaki teaches shortening the time constant or provid-
ing a smaller impedance during the first period. Turning to
figure 9a, we agree with the Examiner that t6 shows a smaller
period than periods T1-T6. However, we fail to find that the
Examiner has pointed to any evidence that Yamazaki teaches
applying a voltage to the pixels during the first time period
having a smaller time constant than a second time period. In
addition, we fail to find that the Examiner has pointed to any
evidence in Yamazaki that teaches a control circuit which
controls the voltage divider circuit to select a first voltage
in a manner that an output impedance of said voltage divider
circuit is smaller in said first period than the output imped-
ance in said second period. In addition, we fail to find that
Yamazaki provides any suggestion to modify the Yamazaki cir-
cuits to provide these limitations.
The Federal Circuit states that "[t]he mere fact
that the prior art may be modified in the manner suggested by
the Examiner does not make the modification obvious unless the
prior art suggested the desirability of the modification." In
