Other Parts Discussed in Thread: DLPC910, DLPC410
Hello,
at the momemt i'm trying to evaluate, if a DMD would be suitable for a technology change within our machines. Actually there are some questions that I cannot answer by only reviewing the data sheets and app notes. I'm quite new to this technology and apologize in advance for too stupid questions( ..and bad english).
Reliability:
I found a TI document, where the lifecycle of a DMD is declared to 120.000 operation hours= 120 Years in a typical portable buisness projector. What does that mean? If i would switch all mirrors continiously with a frequ. of 23KHz and keep all restrictions regarding thermal stress,would it still work over the 120k operation hours??
Are there any other parameters except the thermal influences created by electrical consumption and absorbed light that may limit the lifetime (certain wavelength that are more critical or create aging)?
Efficiancy:
we will be working with a violet light source of 405nm. The responsivity of the DL7000 is 95% at this wavelength, in comparsion with the UV version where it is much closer to 100%. If we keep all restrictions regarding thermal parameters, wouldn't be the DL7000 suitable too? (..also because the UV Version 5x more expensive)
Modes of Operation:
As we would like to shift the image through the DMD, i supposed that the only way is to transfer the whole image again and again. Unfortnalety this results in a incredible amount of data rate between the FPGA and the video controller. Is there a video controller that support some kind of row data shifting? Means : FIFO Update the image with a single row where 1. the existing image is shifted by 1 row (the olderst row is disposed ) and 2. the new data row is added.
Thanks for your help.
