1. A mobile station, comprising:
- a chassis having a display;
a power reducer configured to control power consumption of said display; and
a proximity sensor coupled to said chassis and configured to cause said power consumption to be reduced when said display is within a predetermined range of an external object; and
a microprocessor coupled to said proximity sensor and coupled to said display, said microprocessor configured to automatically activate said proximity sensor based on said mobile station receiving an incoming wireless telephone call.

Abstract
In one embodiment, a mobile station including a chassis having a display, a power reducer, a proximity sensor, and a microprocessor. The power reducer controls power consumption of the display. The proximity sensor is coupled to the chassis and causes the power consumption to be reduced when the display is within a predetermined range of an external object. The microprocessor is coupled to the proximity sensor and to the display and automatically activates the proximity sensor based on the mobile station receiving an incoming wireless telephone call.
