Abstract
A mobile terminal includes a first body structured to slideably engage a second body to permit opening and closing of the mobile terminal by relative sliding motion between the first body and the second body. The first body includes a plurality of distinct optically transmissive regions. A display is positioned relative to the first body at one of the distinct optically transmissive regions, and a keypad is positioned relative to the second body. The mobile terminal also includes a selection key for operatively coupling to an underlying touch pad, such that the selection key is identified by one of the distinct optically transmissive regions of the first body. The mobile terminal further includes back-lighted directional keys for operatively coupling to the underlying touch pad. Each of the directional keys is individually identified by one of the distinct optically transmissive regions of the first body, such that the directional keys are positioned at various locations relative to an outer perimeter of the selection key.
