6.5 DMD Image Performance Specification

Table 6-1 DMD Image Performance
PARAMETER(1)(2) MIN NOM MAX UNIT
Dark Blemishes—Viewed on a linear blue 60 screen(3) 4
Light Blemishes—Viewed on a linear gray 10 screen 4
Bright Pixels—Viewed on a linear gray 10 screen 0 micromirrors
Dark Pixels—Viewed on a white screen 4 micromirrors
(1) See the System Optical Considerations section.
(2) Blemish counts do not include reflections or shadows of the same artifact. Any artifact that is not specifically called out in this table is acceptable. Viewing distance must be > 60 inches. Screen size must be similar to application image size. All values referenced are in linear gamma. Non-linear gamma curves may be running by default, and are assured by a TI applications engineer that the equivalent linear gamma value as specified is used to judge artifacts.
(3) Linear gray 5 may be substituted in monochrome applications.
