Appeal No. 2006-1726
Application No. 09/725,849
plurality of gate drive circuits connected in series, wherein the
gate driver issues a gate pulse signal pulse having two gate
pulses within a single frame interval, and wherein the issued
gate pulse is used for charging the pixel elements.
We agree with Appellants that the combination of Takahashi
and Kubota is not proper to render claim 18 obvious. As noted in
the discussion above, the Takahashi reference teaches providing a
first selecting voltage as a scanning signal in a first
horizontal period to charge the liquid crystal pixels. The
Takahashi reference also teaches providing a second selecting
voltage in the second half of a second horizontal period to
discharge the overcharge voltage across the liquid crystal pixel
cells. We note that the Kubota reference is relied upon for its
teaching of a scanning line driver circuit and a signal line
driver circuit being divided into a plurality of series connected
unit circuits. See column 4, lines 29-32. We note, however,
that the combination of Takahashi and Kubota does not teach the
claimed limitation of issuing a gate pulse signal for charging
the pixel elements, wherein the signal pulse signal includes two
gate pulses within a single frame interval.
