Which term describes a controller-mounted device that consists of a small number of keys and a small display?

Explanation:
This item focuses on the local operator interface mounted on a controller, a compact device that lets you enter commands or setpoints and read status with just a few keys and a small display. The best term for this is keypad display, because it pairs a small keypad input with a tiny screen to show prompts or values right at the controller. A dumb terminal is typically a separate interface to a larger computer system and usually isn’t a tiny, controller-mounted device with limited keys. An alarm printer serves only to print alarms and has no display for interactive control. A notebook PC is a full-size computer, not the small, specialized input-and-display unit described here.
