Display
The PEBL U3 features a 1.9-inch TFT display with 256K colors, offering a modest resolution of 128 x 160 pixels, translating to around 108 ppi density. For its era, the screen provided adequate clarity for basic phone operations, though it is small compared to modern standards. Additionally, an external monochrome display with a 96 x 32 pixel resolution offers basic information like time and notifications, adding a practical dimension to the design without compromising its sleek aesthetic.
