Other Parts Discussed in Thread: DLP2000
Hello,
I'm trying to determine that my chosen operating conditions are not too harsh for my DMD. In my application, most micromirrors spend a majority of the time in the off-state under intense light power.
The following document details how to calculate T_array for a non-uniformly illuminated partial DMD array: https://www.ti.com/lit/an/dlpa104/dlpa104.pdf?ts=1671473594157&ref_url=https%253A%252F%252Fwww.google.com%252F
Clearly, one of the pieces of information I need for this calculation is the off-state fill factor, FF_off-state-mirror. However, this is not specified in the datasheets for the DLP2000 or DLP9000, both of which have 7.6 um-pitch micromirrors. The document above gives FF_off-state-mirror = 75.3% for the 10.8 um-pitch micromirror DMDs, but I believe it should be slightly lower for DMDs with a smaller micromirror pitch.
I'd very much appreciate if you could share the needed information for all DMD types. I also understand this number might depend on illumination angle, but a nominal value (within 1%) would suffice.
Thank you very much!
