in independent form including all of the limitations of the base
claim and any intervening claims.
We affirm-in-part.
BACKGROUND
Appellants’ invention is directed to large-area display
devices which are formed as an array of tiled display devices.
The need exists for displays in which picture elements (pixels)
can be brought up to the very edge, within ½ pixel spacing period
of the edge, while the electronics circuitry can address each
tile (specification, page 2). The impediments to such approach
are visibility of the seams between tiles and electrical access
to the pixels (id.).
According to Appellants, the conventional structure of
providing drive circuitry on the back of the display and passing
vias through the structure from the back to the front and to each
pixel electrode may be improved by providing pixel structure on
each tile having a relatively small active region (specification,
page 3). Thus, as depicted in Figure 3, an electrical via may be
formed within the pixel area without interfering with the active
region of the pixel (id.).
