(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) This represents the variation that can occur between any two individual micromirrors, located on the same device or on different devices.
(4) 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 variations 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.
(5) See Figure 5-16.
(6) Conditions of acceptance. All DMD image performance returns are 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 60 inches.
  • The projections screen shall be a 1× gain.
  • The projected image shall be inspected from an 8-foot minimum viewing distance.
  • The image shall be in focus during all image performance tests.
(7) Bright pixel definition: a single pixel or mirror that is stuck in the ON position and is visibly brighter than the surrounding pixels.
(8) Dark pixel definition: a single pixel or mirror that is stuck in the OFF position and is visibly darker than the surrounding pixels.
(9) POM definition: The rectangular border of off-state mirrors surrounding the active area.
(10) Gray 10 screen definition: A full screen with RGB values set to R=10/255, G=10/255, B=10/255.
(11) White screen definition: A full screen with RGB values set to R=255/255, G=255/255, B=255/255.
(12) Adjacent pixel definition: Two or more stuck pixels sharing a common border or common point. Also referred to as a cluster
(13) 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.
