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").Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
