Appeal No. 95-3890
Application 08/023,665
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 1-5, which constitute all
the claims in the application.
The claimed invention pertains to a display device having
picture electrodes arranged in rows and columns. One aspect of
the invention is that picture elements in consecutive rows are
offset with respect to each other by a distance covering half a
pitch. Another aspect of the invention is that various wiring
components of the device are arranged substantially mirror-
symmetrically with respect to a direction transverse to the row
direction for pixels associated with consecutive rows.
Representative claim 1 is reproduced as follows:
1. A display device comprising an electro-optical
display medium between two supporting plates, a system of pixels
arranged in rows and columns, with each pixel being formed by
picture electrodes arranged on the facing surfaces of the
supporting plates, and a system of row and column electrodes for
presenting selection and data signals, a picture electrode on one
of the supporting plates being connected in an electrically
conducting manner to a first switching unit between a column
electrode for data signals and the picture electrode and to a
second switching unit between the picture electrode and an
electrode for a reference voltage, characterized in that the
pixels in consecutive rows are offset with respect to each other
in the row direction by a distance covering half a pitch, and in
that the patterns of switching units, picture electrodes, column
electrodes and electordes for the reference voltage are arranged
substantially mirror-symmetrically with respect to a direction
transverse to the row direction for pixels associated with
consecutive rows.
