Part Number: DLP6500FYE

Hi All,

Thanks for your time.

https://e2e.ti.com/support/dlp/f/94/p/741058/2737139?tisearch=e2e-sitesearch&keymatch=DLP6500%2520display%2520dim#2737139

I saw this post and my customer have a similar issue like this. May I ask what is the cause to this issue?

Best regards,

Kevin

  • Kevin,

    Is your customer designing their own board (especially thier own flex cable)?  

    We were never able to determine the root cause, but the customer was designing their own board and DMD board and apparently had not correctly connected the signals.

    Hi Fizix,

    Many thanks for your reply.

    Yes, My customer designed their own board. But they didn't use flex cable but a connection finger.

    And their connection is as below:

    DLPC900 DLP6500FYE
    DDA_P[15:0] D_BP[0:15]
    DDA_N[15:0] D_BN[0:15]
    DCKA_P DCLK_BP
    DCKA_N DCLK_BN
    SCA_P SCTRL_BP
    SCA_N SCTRL_BN


    DDB_P[15:0] D_AP[0:15]
    DDB_N[15:0] D_AN[0:15]
    DCKB_P DCLK_AP
    DCKB_N DCLK_AN
    SCB_P SCTRL_AP
    SCB_N SCTRL_AN

    I also let customer do the DMD bus swap of the firmware. But it didn't work. It is same in Pre-srored Pattern Mode and Internal test pattern.

    Do you need the schematic?

    Best regards,

    Kevin

    Thanks
