Appeal No. 1998-1319
Application No. 08/466,188
selectable, there must be plural voltages. Therefore, we have
interpreted "voltage selecting data" as plural voltages.
Similarly, claim 44 includes a circuit "for converting said
... multi-tone image data into voltage selecting data."
Accordingly, we have interpreted claim 44 as including the
production of plural voltages.
In addition, claims 9, 10, 15, 28, 29, and 34 through 44
specify that the voltage output to the matrix display has a
constant voltage level during a horizontal scanning period.
In particular, claims 9, 10, 28, and 44 recite a voltage
output having "a constant voltage level" for (claims 9 and 10)
or during (claims 28 and 44) "one horizontal scanning period."
Claim 15 recites supplying a voltage having "a constant
voltage level ... in a period for latching data for one
horizontal line." Claims 34 through 43 recite "outputting a
multi-tone voltage having a constant voltage level during one
horizontal scanning period." Claim 29 includes "voltage
selecting means for selecting one of said tone voltages ...
during one horizontal scanning period." Since only a single
voltage is selected during the horizontal scanning period, we
