摘要： A portable computing device and a display housing module for a portable computing device is disclosed. The display housing module includes a conductive rear chassis, a display module and a front bezel. The display module is configured to display images and includes a backlight unit, a display panel, and a touch screen. The conductive rear chassis is strong, lightweight, and rigid. It is configured to receive and secure the display module and to protect the display module from shock events, drop events, and vibration. The conductive rear chassis may provide a conductive path to a ground connection. This prevents EMI from affecting an antenna signal by channeling EMI originating from noisy electronics to ground, thereby preventing unwanted EMI leakage outside of the display module. The conductive rear chassis is further configured to receive an environmental sealer around the perimeter of the housing. The conductive rear chassis is further configured for direct attachment to a front bezel. Attaching the front bezel to the conductive rear chassis creates pressure on the environmental sealer and allows the internal display parts to function properly without regard to environmental elements.
