Appeal No. 2005-1997 Page 4
Application No. 09/493,319
A further understanding of the invention can be achieved by reading the following
claims.
45. A method comprising:
providing a light modulator comprising an array of pixel cells and
memory buffers, each memory buffer being associated with a different
group of two or more of the pixel cells and each memory buffer being
located closer to the associated group of pixel cells than another one of
the group of pixel cells; and
during a refresh operation, converting the digital indications stored
in the memory buffers into analog voltages to update charge intensities on
the pixel cells.
50. A light modulator comprising:
an array of pixel cells;
memory buffers being spatially distributed among the pixel cells,
each memory buffer being associated with a different group of two or more
of the pixel cells and storing a digital indications [sic] of associated
predetermined voltages; and
digital-to-analog converters to convert the digital indications into
analog voltages to update charges on the pixel cells during a refresh
operation.
Claims 45-48 and 50-54 stand rejected under 35 U.S.C. § 103(a) as obvious over
U.S. Patent No. 6,333,737 ("Nakajima") and U.S. Patent No. 6,297,787 ("Nishida").
