I know of CyberBadge from Poland, which is making a very primitive version of what you're describing. They don't have a screen, just an array of programmable led lights. People use them at events. https://cyberbadge.net/

Cool. Badges, commemorative pins, small tradable items are mainstays at cons, conferences etc., their market doesn't need to be created, it's their to be fed.
So make this type of thing work across time and you have created value to someone, which means a marketable product, at least in the Slashdot sense of ?, ?, 3... profit!.
