DLP480RE: dlpc 4422 interface with dlp480re

Part Number: DLP480RE
Other Parts Discussed in Thread: DLPC4422,

hello all,

i want to use ti dlp480re dmd for my application. i read the datasheet and other descriptions, and concluded that it requires dlpc4422 asic for functioning.

in my application it is only used for display a binary image of the high resolution so requires dmd micromirror only in fully on condition or fully off condition at any instant of time.

the resolution requirement is perfectly matching the dmd480re(1920x1200). but i don't require to use video or pattern mode, only  a constant white display for few seconds and then a black out followed for few more seconds and repetition of this process for about 100 images.

my confusion is can i bypass all the facilities of dlpc4422 for video and image processing. and use a mode of dlpc4422 which can display a binary image (pure black and white and not even gray)

also can i use any other simpler medium which can load the dmd directly (maintaining voltage and temperature in healthy condition).

please guide me for the application.

  • Hello Pratik,

    Welcome to the DLP section of the TI-E2E forums.

    May i get some more information about your application? Are you planning on using an external source for the black and white images?

    Regards,

  • Dear oscar,

    Yes, exactly. I am using external source of LED illumination for black and white image . I also restrict the illumination within maximum rating.

    I need a very simple control of dmd as my images are displayed at very low frame rate.

    480re is best for resolution i required

    Please suggest something

  • Hi Pratik,

    For the DLP480RE DMD you will need the DLPC4422 asic and the DLPC4422GUI controller software for basic operation. In the GUI you can disable any unnecessary video function to suit your needs.

    Please refer the reference design to help you get started.
