Electronic displays encounter visibility issues due to varying ambient light conditions. An ambient light sensor can be provided to sense ambient light and dynamically adjust display brightness to compensate for changes in ambient light. A wave guide for improving angular response in a light sensor is provided.

Wave guide for improving light sensor angular response

A system and method for optically identifying a component coupled to an electronic device is provided. The method includes emitting light from within the device toward a surface of a component connector inserted into a receiving socket of the device. A light sensor senses the intensity, amplitude or wavelength of light reflected from a surface of the component connector. A processor of the device identifies the component based on the intensity, amplitude or wavelength of light reflected from a surface of the component connector. The processor modifies at least one setting of the electronic device in response to the identification of the component.

Optical detection of a component for an electronic device

A method is set forth for automatically adjusting keypad brightness on a mobile electronic device having a light sensor, a keypad and a backlight for said keypad, comprising obtaining light level samples from the light sensor, turning the backlight from off to on in the event a current light level sample is less than a threshold value below which backlight illumination becomes necessary in order to read the keypad, and from off to on after a predetermined time period in the event the current light level sample is greater than the threshold value.
