(1) Measured relative to the plane formed by the overall micromirror array.
(2) Additional variation exists between the micromirror array and the package datums.
(3) When the micromirror array is landed (not parked), the tilt direction of each individual micromirror is dictated by the binary contents of the CMOS memory cell associated with each individual micromirror. A binary value of 1 results in a micromirror landing in the ON State direction. A binary value of 0 results in a micromirror landing in the OFF State direction.
(4) Represents the landed tilt angle variation relative to the nominal landed tilt angle.
(5) Represents the variation that can occur between any two individual micromirrors, located on the same device or located on different devices.
(6) For some applications, it is critical to account for the micromirror tilt angle variation in the overall system optical design. With some system optical designs, the micromirror tilt angle variation within a device may result in perceivable non-uniformities in the light field reflected from the micromirror array. With some system optical designs, the micromirror tilt angle variation between devices may result in colorimetry variations, system efficiency variations or system contrast variations.
(7) Micromirror tilt direction is measured as in a typical polar coordinate system: measuring counter-clockwise from a 0° reference which is aligned with the +X Cartesian axis.
(8) Conditions of Acceptance: All DMD image quality returns will be evaluated using the following projected image test conditions:
       Test set degamma shall be linear
       Test set brightness and contrast shall be set to nominal
       The diagonal size of the projected image shall be a minimum of 20 inches
       The projections screen shall be 1X gain
       The projected image shall be inspected from a 38 inch minimum viewing distance
       The image shall be in focus during all image quality tests
(9) Bright pixel definition: A single pixel or mirror that is stuck in the ON position and is visibly brighter than the surrounding pixels
(10) Gray 10 screen definition: All areas of the screen are colored with the following settings:
      Red = 10/255
      Green = 10/255
      Blue = 10/255
(11) POM definition: Rectangular border of off-state mirrors surrounding the active area
(12) Dark pixel definition: A single pixel or mirror that is stuck in the OFF position and is visibly darker than the surrounding pixels
(13) Adjacent pixel definition: Two or more stuck pixels sharing a common border or common point, also referred to as a cluster
(14) Unstable pixel definition: A single pixel or mirror that does not operate in sequence with parameters loaded into memory. The unstable pixel appears to be flickering asynchronously with the image
