Claim:
A mobile communication device, comprising: a display that includes: at least one light source, a light guide, and a plurality of variable reflecting components, where each of the plurality of variable reflecting components is disposed over a respective portion of the light guide, where each of the variable reflecting components is to operate in one of a partially transmissive mode or a partially reflective mode; and a processor to: adjust each of the plurality of variable reflecting components to operate in the partially transmissive mode or the partially reflective mode based on an amount of ambient light, where, when the mobile communication device executes a first application, a first subset of the plurality of variable reflecting components is in one of the partially transmissive mode or the partially reflective mode based on the amount of ambient light, and where, when the mobile communication device executes a second application, a second subset of the plurality of variable reflecting components, that differs from the first subset, is in one of the partially transmissive mode or the partially reflective mode based on the amount of ambient light.
