Display
In terms of display, the BenQ A520 comes with a primary OLED screen that supports 65K colors. Despite its limited size of just 1.5 inches, with a resolution of 128 x 128 pixels (~121 ppi density), the screen was sufficient for its intended use during its time. The device also includes a secondary, smaller OLED display with a resolution of 96 x 39 pixels, which adds a touch of convenience by providing quick access to notifications without activating the main screen.
