Display
The Plum Signal sports a modest 1.8-inch TFT display, with a resolution of 160 x 120 pixels. This screen size and resolution are minimal by modern standards, offering a pixel density of roughly 111 ppi. The limited screen-to-body ratio of approximately 24.2% emphasizes its primary function as a communication device rather than a multimedia tool. Nevertheless, for basic text and call functionalities, the display serves its purpose without any extravagant features.
