Appeal No. 96-2025
Application 07/860,254
DECISION ON APPEAL
This is a decision on appeal from the final rejection of
claims 1 through 9, all of the claims present in the
application.
The invention relates to a method and an apparatus for
driving display devices such as an ac driven capacitive flat
matrix display panel. On page 20 of the specification,
Appellants disclose that Figure 6 shows the waveform of the
voltage applied to a corresponding picture element. In
particular, Figure 6 (1) shows a waveform of a modulation
voltage Vm applied from the data side electrode X. Figure 6
(2) shows the waveform of a writing voltage -Vm, +Vp applied
from the scanning side electrode Y. Figure 6 (3) shows the
waveform of a voltage applied to a picture element.
Appellants disclose on page 21 of the specification that
as shown in Figure 6 (1), the pulse width of the modulation
voltage VM for the first field of negative driving is
determined by the graduation display data at the time of input
to the data conversion circuit 18. Furthermore, Figure 6 (1)
