Screen dimensions are the device’s active display area, not protector cut dimensions. Cut sizes depend on bezel geometry and adhesive design and are confirmed with the supplier before any production run. Housing dimensions are the overall device body, not the screen. Aspect ratio and pixel density are derived from the sourced values above.
