Mobile terminal with back-lighted directional keys
First Claim
1. A mobile terminal, comprising:
- a first body structured to slideably engage a second body to permit opening and closing of said mobile terminal by relative sliding motion between said first body and said second body, wherein said first body comprises an optically opaque region and a plurality of distinct optically transmissive regions which are defined by said optically opaque region;
a display on said first body at one of said plurality of distinct optically transmissive regions;
a keypad on said second body;
a selection key operatively coupled to an underlying touch pad, wherein said selection key is defined by one of said plurality of distinct optically transmissive regions of said first body;
a plurality of directional keys operatively coupled to said underlying touch pad, wherein each of said plurality of directional keys is individually defined by one of said plurality of distinct optically transmissive regions of said first body, and wherein said plurality of directional keys are positioned at various locations relative to an outer perimeter of said selection key; and
a plurality of light guides formed in said touch pad, each of said plurality of light guides being individually associated with one of said selection key and said plurality of directional keys,wherein the optically opaque region and the plurality of distinct optically transmissive regions are all coplanar.

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.
