Q: What are the definitions for the Gateway 56-inch RPTV?A: Definitions:
Blemish - A blemish is an obstruction, reflection, or refraction of light that is visible, but out of focus in the projected image under specified conditions of inspection. It is cause by a particle, scratch, or other artifact located in the image illumination path.
Dark Pixel - A single pixel or mirror that is stuck in the OFF position and is visibly darker than the surrounding pixels.
Bright Pixel - A single pixel of mirror that is stuck in the ON position and is visibly brighter than the surrounding pixels.
Unstable Pixel - 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.
Adjacent Pixel - two or more stuck pixels sharing a common border or common point. Also referred to as a cluster.
Streaks - Artifact resulting from localized variations in mirror tilt angle relative to surrounding mirrors. They are similar in appearance to window scratches but appear at the mirror level. Streaks appear as faint diagonal or arcing patterns in the image.
Eye catcher - A small localized light "spot" which has high spatial frequency and high differential brightness. These are due to various DMD window or window aperture "defects" including: digs, voids, particles and scratches.
Border Artifacts - A general category of image artifacts that may show up on screen in the area outside of the active array. Border artifacts include: exposed bond wires, exposed metal 2, and reflective edge.
