Abstract
A portable wireless communication device having a display screen, a light source that is capable of illuminating the display screen, and a processor coupled to the light source, dynamically adjusts a period of time during which the display screen is illuminated. The processor couples power to the light source to illuminate the display screen, determines at least one illumination time parameter associated with information to be displayed on the display screen, and maintains a coupling of power to the light source for a period of time that is based on the at least one illumination time parameter. In other embodiments of the present invention, the processor may further determine to not illuminate the display screen, or to terminate illumination of the display screen prior to expiration of the period of time, based on a received instruction or a detected level of ambient light.
