Appeal No. 1998-3064 Page 2
Application No. 08/445,867
BACKGROUND
The invention at issue in this appeal relates to a liquid
crystal display (LCD). Specifically, the invention is
circuitry for reading data from and writing data to the
addressable display space of the LCD. The circuitry includes
a common drive circuit and a plurality of segment-drive
circuits. Under control of a central processing unit (CPU),
the circuitry reads data from and writes data to addressable
positions of the display space in a row-direction or a column-
direction or both. Such circuitry is particularly useful for
LCDS having long rows.
Claim 7, which is representative for our purposes,
follows:
7. A display control circuit for a display unit having
a plurality of addressable positions arranged in a matrix,
comprising:
a plurality of segment drive circuits connected
to the display unit in a line writing/reading
direction, each said segment drive circuit being
provided for the writing/reading of data to/from
only a predetermined addressing range of addressable
positions of a total range of addressable positions
of the matrix, said predetermined addressing range
of addressable positions being in the line
