The active area (AA) is the part of the display that presents graphical content (images, text, interface elements). It does not include bezels, margins or dead zones. The dimensions of the active area are crucial during device design – they must match the opening in the housing or the size of the protective cover glass. In specifications, the AA parameter is usually given in millimeters and defines the exact size of the visible working surface, which is especially important when fitting the display into panel cutouts or glass covers.
