may be fabricated in both one and two dimensional arrays, the
deformable mirror, the discussion of which begins at col. 4,
lines 5 to 11 and indicates that they may be utilized in
linear or areal patterns for display purposes. Thus, it would
have been apparent to the artisan that these teachings of
Hornbeck clearly cross correlate and indicate the
substitutability of the DMD devices of Hornbeck for the prior
art approach depicted by the Collender/Ernstoff approach.
Indeed, the linear and areal arrays of pixels, each of which
may be individually addressable and containing at least one
deflectable reflecting beam of light, form the essence of the
teachings in Hornbeck beginning at col. 9, line 15. His
spatial light modulators were also therefore called deformable
mirror devices DMDs. From a study of Ernstoff’s structure
providing the color image capability of Collender’s device,
each pixel or cell in Ernstoff would apparently be
substantially colorless until the dichroic mirrors were placed
in such a position as to reflect a certain color to the viewer
for each pixel or cell. In a similar manner, the
deflectability of the reflecting beam of the spatial light
modulators in Hornbeck would have achieved the same effect by
