Appeal No. 1997-0799
Application 08/242,235
Representative claim 1 is reproduced below:
1. A plasma-addressed liquid crystal display device,
comprising:
a liquid crystal cell having a plurality of data
electrodes therein;
a plasma cell associated with the liquid crystal cell and
having a plurality of discharge channels with discharge
electrodes, the liquid crystal cell and the plasma cell being
disposed spaced-apart with the direction of the discharge
channels transverse to that of the data electrodes and spaced
from each other:
a scanning circuit operable to control an application of
discharge pulses to said discharge electrodes in the discharge
channels by a row scan operation; and
a driving circuit provided to apply data voltages to the
respective data electrodes,
wherein said driving circuit includes means for
substantially eliminating an increase in voltage between said
discharge electrodes and said data electrodes during the
application of the discharge pulse.
