BeagleBone Black LCD. HELP

I am trying to make a BBB that connects to a small (4.3" or smaller) LCD that will fit on my wrist, i plan to have it hooked up to a battery and be able to run Android and Ubuntu (without any extra drivers if possible). So far, it looks like i am going to have to get a shield display for the black and fit the whole assembly on my wrist, not including the battery. Any ideas for a display that would work? thanks!
