DLPC900: Why does the DLPC 900 and similar DLP Technologies take Video Input?

Nigel Ng
Prodigy 85 points
Part Number: DLPC900

Tool/software:

I am confused on how video/HDMI/VGA fit into the DLP application circuit. My goal is to use the DLPC 900 and DLP 6500FYE for confocal microscopy. All I want is the reflective pattern from the DMD. 

How do I use the DLP for confocal microscopy instead of projection? What does the video input do? Is this the same as inputting patterns?

    Hello again Nigel,

    The DLPC900 is a video chip with special firmware that supports structured light and other industrial applications.  The controller has a DRAM to hold about 400 binary patterns and can store more patterns in flash memory to display directly.

    Some customers want to be able to stream data over video to display because 400 binary patterns is not enough.  For example there are a number of companies that want to stream patterns continuously for say 3D printing.  

    For testing the EVM is supplied with a HDMI/DP receiver to accommodate this.

    For confocal microscopy you may want to look at something from one of our design partners.  Try this search tool: https://www.ti.com/tool/DLP-OMM-SEARCH
