Appendix C

DMD Image Quality

1. SCOPE

This document specifies the image quality requirements applicable to the DLP

TM

XGA Component Set.

The Component Set provides the DLP

TM

XGA Projector with digital imaging functionality based on

Digital Micromirror Device (DMD) technology.

2. Definitions

2.1 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 (see Table 1). It is caused by a
particle, scratch, or other artifact located in the image illumination path.

2.2 Dark pixel

A single pixel or mirror that is stuck in the OFF position and is visibly darker than the
surrounding pixels.

2.3 Bright pixel

A single pixel or mirror that is stuck in the ON position and is visibly brighter than the
surrounding pixels.

2.4 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.

2.5 Adjacent pixel

Two or more stuck pixels sharing a common border or common point, also referred to as a
cluster.

2.6 Streaks

Artifact resulting from locallized variation 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.

2.7

Sea of Mirrors (SOM)

SOM is a rectangular array of off-state mirrors surrounding the active area.

2.8 Eyecatcher

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.

2.9 Border

Artifacts

All variations of these artifacts are acceptable under this image quality specification.
Border artifacts are 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.
