contacts of a matrix pixel structure (answer, page 11).
Therefore, we find Appellants’ arguments (brief, page 23) that
because Mazurek relates to a tiled LCD display, “it would not be
obvious to mount any electronic circuitry on the back of the
display tile disclosed by Mazurek” to be unpersuasive. Mazurek,
in fact, provides for the driving circuitry on a circuit board as
a part of each display tile (col. 3, lines 24-26) which as
depicted in Figures 24 and 25, includes circuit 1810 for
controlling the image display, timing control circuit 2010 and
frame memory units 2030/2040 on the circuit board associated with
each tile (col. 21, line 60 through col. 22, line 8). Therefore,
one of ordinary skill in the art would have combined the
references and would have used the via holes of Wei for
connecting the contacts of the matrix display with the contacts
on the top surface of the circuit board in the tiled display of
Mazurek. In this case the reason for the modification comes not
only from the benefits of using the via holes for providing the
connections in Wei but from the need for such compact arrangement
disclosed in Mazurek where the memory, the drive circuitry and
the timing circuitry are on the circuit board surface opposite to
the pixel structure.
We also observe that although Spindt may be applicable only
in rejecting the claims that recite a cathodoluminescent display
