DS90UB947-Q1: Support Dual-display

Hi team,

1. can 947 + 948 support below configuration, i.e. GPU drive 2x 947 using the same OpenLDI? 

2. assuming #1 is working, can send different contents to the two displays using the same OpenLDI?

    Hello Pengyu,

    Yes this is possible as long as the GPU can generate an image to send to the OLDI port in alternating pixel format. Meaning that every other pixel of the video line is corresponding to the content of the two displays. Also the two displays must have the same video dimensions, timing, and frame rate. 

    Here is a report showing an example bench validation that was done for this feature: 947_Validation_Odd_Even_on_FPD3.pdf

    Best Regards,

    Casey
