The fact that you say your trying to hide that your reading lyrics in front of an audience says something right there I wont go any further,.... What Sinatra (RIP) and all the big acts do wherever isn't of my concern as many things that go on with
big money acts no one ever sees or knows anyway behind the scenes.
Looking and reading words on a page and trying to look into the faces of the audience isn't gonna happen and you will look awkward
and then looking at your hands playing too?
Well if that doesn't bother the player and his stage presence then have fun,......but I learned and always watched the pros play & sing effortlessly in front of me on stage and look and smile with your eyes open into the audiences eyes to make contact, it's part of the overall act and visual stage persona.

Donny, if what Sinatra et al do isn't your concern, then who are the 'pros' you are talking about, that play and sing effortlessly on stage?
I turned 78 years old a couple of weeks ago, and yes, I have a tablet on my KB stand ... and I personally think my stage presence, eye contact with the audience, etc. is pretty damned good ... about 95% of my gigs these days are not in nursing homes, but rather in some pretty up-scale assisted or independent living venues where the audience is fully aware of what is going on, and after each performance I have people coming up and telling me how much they enjoyed it, etc. etc., and not ONE has ever said, "oh I saw you looking at the lyrics" ... so yes, I will continue to perform the way I have been and continue to have fun, but MOST OF ALL, I will continue to please my audiences ...
