Appeal No. 2006-2443
Application No. 10/012,968
The examiner’s response is that Kuribayashi’s clear signals
are equivalent to the claimed “auto-zero signals” and these clear
signals are applied to the display panel to clear the display
panel into a black/white state. The examiner’s conclusion is
that “[c]learly, these clear signals will clear out any voltage
accumulated in the pixels so that the picture area is cleared
into black/white” (answer-page 5). The examiner further notes
that it is “known that a liquid crystal display has a drawback
that pixels in the liquid crystal display act as capacitors
accumulate charges after signals are remove from the display
panel. Thus, it is clear that Kuribayashi teaches applying the
auto-zero signals (the clear signals) to bleed off accumulated
charge in the pixels” (sic, answer-page 5).
Appellants respond, in the reply brief, by contending that
the clearing signal in Kuribayashi is applied before the scanning
selection signal and the “purpose of the clearing signal is to
place each pixel in a known state prior to applying the scanning
selection signal” (reply brief-page 1), but appellants contend,
the black state in Kuribayashi does not correspond to the
situation where a charge has been bled off. As evidence of this
position, appellants point to Figure 7A of Kuribayashi and note
