Patent ID: 7982690

Claim:
A micromirror device for applying a digital image data to display an image comprising: a plurality of pixel elements arranged in a form of an array and grouped into B subsets each including pixel elements configured as M s columns and N s rows represented by M s (COLUMNs)×N s (ROWs) wherein-M s , N s and B are positive integers; each of said pixel elements has a mirror, and at least one memory cell to pulse width modulate (PWM) an incident light; the memory cell has a transistor of an input gate capacity C t [F]; each memory cell is connected by a ROW line having a wiring resistance R[ 106 ], and a wiring capacity C[F]; and wherein the parameters represented by M s , N s , B, C t , R, C, and a number of colors represented by C 0 have a relationship of R*(C t +C)<(1.63*10 −5 *B)/[C o *M s *N s *(M s +1)], when a gray scale display of 10 bits or more for each color is presented with a color sequential display of C 0 colors.
