Abstract

A device and method for detecting lighting conditions to enable brightness control of a display are disclosed. The device includes a display and a first photodiode array to detect light in a visible spectrum and a non-visible spectrum that is incident on the first photodiode array. The device also includes a second photodiode array to detect light in the non-visible spectrum that is incident on the second photodiode array, and a processor to determine the lighting conditions based on a first output of the first photodiode array and a second output of the second photodiode array. The processor adjusts the first output used to determine the lighting conditions based on detecting that the first photodiode array includes a shadowed region, and controls the brightness of the display based on the lighting conditions.
