Motorola StarTAC Rainbow Display and Interface

Display and Interface

Equipped with an alphanumeric display capable of showing up to 2 x 12 characters and fixed icons, the StarTAC Rainbow’s screen was designed for straightforward phone operations. Although minimalistic by today's standards, it was sufficient for the basic call and messaging functionalities that formed the core of its use. The phone's interface was simple, almost exclusively button-based, which aligned with the technological expectations of the period.
