Abstract
Portable devices (100) that include displays (102) and are used in widely ranging ambient light conditions use selectable or adjustable optoelectronic input/output compensation functions to drive their displays. According to certain embodiments, a camera (122) or a light sensor (120) is used to measure the ambient light level, and an optoelectronic input/output compensation function that is specifically chosen based on the measured ambient light condition is used to drive the display. Furthermore, according to certain embodiments, the optoelectronic input/output compensation function is selected based on whether a display backlight (230) is turned on or off.
