    You should be able to daisy chain displays as you show in your diagram. Things to be aware of would include the lengths of the connections between the panel and the DS90UB925B device - this will represent an unterminated stub, and the trace lengths should not be longer than necessary. Also, the jitter will accumulate on successive links, so using this technique to go to a second display would probably be OK, but extending it to additional displays would likely result in a loss of signal integrity, and eventually the system would not work.
