Video Pattern Mode in DLP LightCrafter 9000 EVM

Hi,

I'm trying to use the Video Pattern Mode to input 1K Hz of pictures in 1 second (every picture is different), and the bit depth is 1, I'm wondering how or what to do to reach the goal. Thanks for answering.

All The Best

    Hi Michael,

    Thanks for posting your question. This forum (DLP LightCrafter Development Platform Forum) is meant for LightCrafter (also known as the LightCrafter3000) questions. Please post questions for the LightCrafter9000 in the 'New DLP Applications & Technology Forum' (e2e.ti.com/.../94). I will move this post over for you.

    Thanks,
    Clinton

    Hi Michael,

    Achieving a frame rate of 1000 Hz with 1000 1-bit pictures is indeed possible on the LightCrafter9000 EVM in Video Pattern Mode.

    For an example of how to set up a Video Pattern Mode pattern sequence, review section 3.6.4 of the User's Guide: http://www.ti.com/lit/dlpu028

    For your application, you'll probably want to add 24 1-bit patterns to a frame with the appropriate timing to achieve your desired frame rate. This process can be repeated with new images to display your desired amount of patterns.

    Let me know if you have any difficulties setting up a pattern after looking through the User's Guide.

    Best regards,

    Trevor

    Hi Trevor,

    Thanks for answering, I will do more study on the User's Guide.

    I got one question here, if my pictures are all 4K x 2K pixels(Ultra High Definition) and cannot be compressed, can I still reach the goal( 1K pictures in 1s ) with this DLP? If it can't, what maximum pixels of picture can I input?

    Best Regards,

    Michael

    Hi Michael,

    The LightCrafter9000 EVM supports WQXGA resolution (2560x1600). This is the maximum number of pixels that can be input and displayed.

    Best regards,
    Trevor
