6.10 Micromirror Array Physical Characteristics

Table 2. Micromirror Array Physical Characteristics

PARAMETER DESCRIPTION VALUE UNIT
Number of active columns (1)(2) M 1920 micromirrors
Number of active rows (1)(2) N 1080 micromirrors
Micromirror (pixel) pitch (1) P 5.4 µm
Micromirror active array width (1) Micromirror pitch × number of active columns 10.368 mm
Micromirror active array height (1) Micromirror pitch × number of active rows 5.832 mm
Micromirror active border (3) Pond of micromirrors (POM) 20 micromirrors/side
(1) See Figure 8.
(2) The fast switching speed of the DMD micromirrors combined with advanced DLP image processing algorithms enables each micromirror to display four distinct pixels on the screen during every frame, resulting in a full 3840 × 2160 pixel image being displayed.
(3) The structure and qualities of the border around the active array includes a band of partially functional micromirrors referred to as the Pond Of Micromirrors (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 the OFF state.
