I've worked on the software side of things. We typically just build web apps and run them using Chrome's kiosk mode (https://blog.suitebriar.com/chrome-kiosk-mode-what-is-it-how-does-it-work https://blog.suitebriar.com/chrome-kiosk-mode-what-is-it-how...). The displays I've worked on generally run on standard touch-enabled TVs on something like an Intel NUC running Windows.
