Electronic devices having ambient light sensors with lens diffusers

Abstract:

An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels configured to display images. A display cover layer may overlap the array of pixels. A light sensor such as a color ambient light sensor may be mounted in the electronic device and may receive ambient light through an ambient light sensor window region in the display cover layer or other portion of the electronic device. A diffuser may be located between the display cover layer and the ambient light sensor. The diffuser may have a substrate such as a glass substrate. A lens layer may be supported by the substrate. The lens layer may be formed from a layer of ultraviolet-light-curable polymer in which an array of lenses has been formed. An infrared-light-blocking-and-visible-light-transmitting filter may be used to reduce infrared light reaching the ambient light sensor.
