Appendix D
DMD Image Quality
1. SCOPE
This document specifies the image quality requirements applicable to the DLP
TM
.7XGA Value
Component Set. The Component Set provides the DLP
TM
.7XGA Value 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
Reset Boundary Artifact
The reset boundary artifact is a single row of pixels on the reset group boundaries that
are visibly darker or lighter than the neighboring rows of pixels.
