I can't read, but was struggling for a while with structures on some songs, so used some index cards subtly clipEd to my bass stand with a small led light taped to it , worked wonderfully, and was discreet
I've seen keyboard players use iPads on brackets that clip to thier bv mic stand and use a software which scrolls the sheets at the correct Bpm , for me to much to go wrong there , and also you can get away with an iPad in a keyboard set up.
Obvioulsy your playing level is way above me, but thought I'd share the iPad software thing, it does seem cool , but I can't help thinking it could go badly wrong.
