7.5.1.3 Illumination Overfill

The active area of the device is surrounded by an aperture on the inside DMD window surface that masks structures of the DMD chip assembly from normal view, and is sized to anticipate several optical operating conditions. Overfill light illuminating the area outside the active array can create artifacts from the mechanical features surrounding the active array and other surface anomalies that may be visible on the screen. The illumination optical system should be designed to limit light flux incident anywhere outside more than 20 pixels from the edge of the active array on all sides. Depending on the particular system’s optical architecture and assembly tolerances, this amount of overfill light on the outside of the active array may still cause artifacts to still be visible.
