5.10 Micromirror Array Physical Characteristics

PARAMETER DESCRIPTION VALUE UNIT
M Number of active columns(1) 4096 micromirrors
N Number of active rows(1) 2176 micromirrors
P Micromirror (pixel) pitch(1) 5.4 μm
Micromirror active array width(1) Micromirror pitch × number of active columns 22.1184 mm
Micromirror active array height(1) Micromirror pitch × number of active rows 11.7504 mm
Micromirror active border (top and bottom)(2) Pond of micromirror (POM) 20 micromirrors/side
Micromirror active border (right and left)(2) Pond of micromirror (POM) 20 micromirrors/side
(1) See Figure 5-13.
(2) The structure and qualities of the border around the active array include a band of partially functional micromirrors called the POM. These micromirrors are structurally and/or electrically prevented from tilting toward the bright or ON state, but still require an electrical bias to tilt toward OFF.
