Tablet to display temperatures

I’m wondering what would be the best option to set up the following:
A little screen on the wall that does only one thing: displays temperatures of three sensors.
No need for clicking on anything, just display of temperatures. Or to be more exact, nobody should be able to click or read anything else on it.

A tablet? NSPanel?

By stable i mean it whatever the device is, it would start displaying that, lets say, dashboard, whenever it is turned on. For example, if it would be a tablet and in case of long power loss, it would go back to that display when power is restored.

Any esphome display should work.
