KlipperScreen is a touchscreen GUI that interfaces with Klipper via Moonraker. It can switch between multiple printers to access them from a single location, and it doesn't even need to run on the same host, you can install it on another device and configure the IP address to access the printer.
KlipperScreen should run on any touchscreen that you can connect to a host (Raspberry, PC, Tablet), but not screens that connect directly to the printer MCU board.
A physical touchscreen is not strictly required, for example you may install a remote desktop server like tigervnc-scraping-server and connect from a client device, check out the hardware page for further information.
KlipperScreen was inspired by OctoScreen and the need for a touchscreen GUI that will natively work with Klipper and Moonraker.
