6.10 Micromirror Array Optical Characteristics

Micromirror tilt—half angle, variation device to device (1) 11 12 13 °

(1) Limits on variability of micromirror tilt half angle are critical in the design of the accompanying optical system. Variations in tilt angle within a device may result in apparent non-uniformities, such as line pairing and image mottling, across the projected image. Variations in the average tilt angle between devices may result in colorimetry and system contrast variations. The specified limits represent the tolerances of the tilt angles within a device.
(2) See Figure 6-9.
(3) Conditions of acceptance: All DMD image quality returns are evaluated using the following projected image test conditions:
       Test set degamma should be linear.
       Test set brightness and contrast should be set to nominal.
       The diagonal size of the projected image should be a minimum of 20 inches.
       The projections screen should be 1X gain.
       The projected image should be inspected from a 38-inch minimum viewing distance.
       The image should be in focus during all image quality tests.
(4) Bright pixel definition: A single pixel or mirror that is stuck in the ON position and is visibly brighter than the surrounding pixels
(5) Gray 10 screen definition: All areas of the screen are colored with the following settings:
      Red = 10/255
      Green = 10/255
      Blue = 10/255
(6) POM definition: Rectangular border of off-state mirrors surrounding the active area
(7) Dark pixel definition: A single pixel or mirror that is stuck in the OFF position and is visibly darker than the surrounding pixels
(8) Adjacent pixel definition: Two or more stuck pixels sharing a common border or common point, also referred to as a cluster
(9) 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.
