You're absolutely right about the UV. Maybe I should say, I don't think it should be so bright you have to wear shades to go outside (though you may still wear them for style, of course!).
And yeah, the basic idea is to have the ceiling (or a central tube, in the case of something like a sphere) covered with LED (or some future equivalent) light panels. I wouldn't call it a giant TV screen because it's not really meant for displaying images... though I suppose, given light panels and how cheap electronics are, there'd be no reason you couldn't turn them on and off to create some animated patterns. (But I assume RGB capability would be quite a lot more expensive than plain white.)
