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.
