Appeal No. 1998-1319
Application No. 08/466,188
As we have indicated above, claim 23 does not require that the
voltage be held constant for a horizontal scanning period.
Further, we find no reference to the image data's being
"multi-tone" in claim 23. As to the selection of one of a
plurality of image data, Aoki's multiplexer 8 selects a
voltage level from V , V , V , and V , which have been output0 2 3 5
from generator 11, in accordance with the gradation signal
generator 7. See, for example, Figure 1 and column 5, lines
11-14. Consequently, appellants' argument is not convincing,
and we will sustain the rejection the claim 23 over Aoki.
Regarding the remaining claims, 30 and 32, appellants'
only argument (Brief, page 11) is that Aoki fails to teach or
suggest "a voltage output circuit which outputs a single
multi-tone voltage having a constant voltage level as the
display voltage according to a decoded result of a decode
circuit of a display dot." However, Aoki's gradation signal
generator 7 decodes the digital image data and forms a
gradation signal as a result of decoding (column 3, lines 38-
43). Aoki's multiplexer 8, or voltage output circuit, selects
and outputs one of V , V , V , and V , or a single multi-tone0 2 3 5
voltage, in accordance with the gradation signal (column 5,
