Electronic device having colored surfaces with neutral transmission

Abstract:

An electronic device may be provided with input-output devices and other components such as optical components that emit light and optical components that detect light. An optical component covering structure may be interposed between an interior region of the electronic device and an exterior region that surrounds the electronic device. The optical components may be formed in the interior region of the electronic device. The optical component covering structure may overlap the optical components. The optical component covering structure may be configured to exhibit a flat visible light transmission spectrum. This neutral light transmission characteristic allows the overlapped optical components to emit and/or receive light through the optical component covering structure without imposing an undesired color cast. The optical component covering structure may include first and second layers with complementary light transmission characteristics. When viewed from the exterior region, the optical component covering structure may exhibit a non-neutral color.
