DLPLCR4500EVM: Custom 6-bit planes

Part Number: DLPLCR4500EVM

Hi,

We're driving the LCR 4500 at 120 hz sending 24-bit RGB data. I'd like to display the first 6-bits of each plane, in order to get 360 hz. To that end I set up my pattern sequence as in the image below, and it validates and plays without throwing any errors. However, when I read back the pattern sequence, it shows as in the second image. This is causing the colors to not display as expected since we aren't displaying the expected bits. 

Is this a limitation of the GUI, or can the LCR not accept anything other than the predefined bit ranges? Is a work around for this to just simulate this with a bunch of single bit frames?

Thanks,

Alex

  • Alex,

    Please see page 32 of the DLPLCR4500EVM User's Guide:

    Which indicates that the groupings cannot be changed.  You will need to pack your bit as shown in the order shown in the readback.  You can write a small utility that will extract and put them into an RGB image in the packing shown to feed to the input.

    Thanks
