DS90UB928Q-Q1: The FPD-Link(LVDS) port is right for the LVDS lcd screen?

Hi Links,

The diagram is mislabeled above, the protocol going into the DS90UB928 RIN+ and RIN- is indeed FPD-Link III, but the protocol on the outputs to the display is OLDI (Open LVDS). TxOUT0-3+/- should correspond to P/NIND0-3, and the TxCLKOUT+/- should correspond to P/NINC of the display.

You may have an older revision of the DS90UB928 datasheet where it does not have the corrected label, but the display should accept this interface.

Please let me know if you have any further questions or need clarifications!

I believe this is RGB device 926, were we discussing the 928?

For specific information on the interface protocol compatibility, please see the section 8.4.2 FPD-Link Input Frame and Color Bit Mapping Select here:
