Appeal No. 95-3408
Application 08/003,448
OPINION
We reverse this rejection.
The above noted language reflects the disclosed feature that
the data select signal 19 alternates between high and low
positions each half of the horizontal period in accordance with
the pulse clock 10 having a frequency twice that of the line
clock 9 wherein N = 2 in accordance with the operation of circuit
figure 9. Stated differently, the processing provided for the
multi-level tone display data common to claims 19 and 20 is that
it is divided into at least two portions and all of the divided
data are provided in one horizontal period of one frame to the
liquid crystal display panel of claim 19 or the multi-level tone
display means at the end of claim 21 on appeal.
On the other hand, the examiner’s position at the bottom of
page 3 of the answer indicates that Barbier requires two complete
scans of the matrix display to completely apply the two kinds of
multi-level display data to the display device in this reference.
We are in agreement with appellants’ characterization at page 4
of the reply brief that Barbier’s system provides the divided
data to a matrix panel in alternate frames. The abstract
indicates that the memory planes in Fig. 2 are read sequentially.
