use of the display tiles in a display device, it does not provide
any suggestion for modifying Wei to implement its display device
as a part of a tiled display (brief, page 22; reply brief, page
4). Appellants further assert that, without a basis for
combining the references and the fact that the LCD display of
Mazurek is a transmissive device, it would not be obvious to
place any electronic circuitry on the back of the display tile of
Mazurek (brief, page 23).
The Examiner’s arguments are focused on the teachings of
Mazurek (col. 3, lines 25-26) that relate to a tiled modular
display having the driving and timing circuitry coupled to the
surface of a circuit board opposite the pixel structure (answer,
page 11). The Examiner also asserts that Wei is relied on for
teaching a circuit board having the pixel driving and timing
circuitry on the surface of the circuit board opposite the pixel
structure (id.), while Spindt discloses a display memory that is
controlled by the display circuit (answer, page 12).
After reviewing Mazurek, we agree with the Examiner that the
reference discloses a tiled modular display wherein each one of
the display modules contains a display driver circuit board. We
also agree with the Examiner that Mazurek may be combined with
the display of Wei wherein a plurality of electrical contacts on
the top surface of a circuit board are coupled to a plurality of
