Pixel
Short for
Picture Element
. The most basic unit of an image. Pixels are arranged in lines and columns. Each pixel corresponds to a micromirror

1080p
projector contains 1080
lines, each consisting of 1920 pixels.
Pond of mirrors
Area around the periphery of the DMD™ containing inactive mirrors. The pond of mirrors may cause artifacts, for example during the edge
