ABSTRACT:
A high-speed infrared ("IR") port and a low-speed IR port are co-located at a notebook computer display panel housing. Both IR ports are directional with a different sensing direction. The high-speed IR port is located along an upper side edge of the display panel housing. The low-speed IR port is located above the display panel along the viewing face of the display panel housing adjacent to the high-speed IR port. The low-speed IR port is disabled while the notebook computer display panel is in the closed position, and is enabled when out of the closed position. Conversely, the high-speed IR port is enabled while the notebook computer display panel is in the closed position and is disabled when out of the closed position. Collocating the ports allows convenient access to each port. The ports share a common electrical interface thereby reducing circuitry.
