Patent attributes
Systems, methods, and computer-readable media are disclosed for ambient light sensing for electronic displays. In one embodiment, a device may include a light guide with a first surface and a second surface, where the light guide has a first refractive index value. The device may include a light sensor mounted on either the first surface or the second surface, the light sensor positioned such that at least a portion of ambient light incident upon the light guide is directed to a detection window of the light sensor, where the detection window has a second material having a second refractive index value. The device may include an adhesive layer configured to optically couple the light sensor to the light guide, the adhesive layer having a third refractive index value equal to or greater than the first refractive index value and equal to or less than the second refractive index value.
