Abstract: An electronic device may be provided with light sensors. The electronic device may have an electronic device housing in which a display is mounted. The display may have a transparent layer such as a transparent display cover layer, a thin-film transistor layer, or a color filter layer. An opaque masking layer such as a layer of black ink may be used to cover an inner surface of the transparent layer in an inactive area of the display. Sensor window openings may be formed in the black ink layer. A layer of ink may be formed in each sensor window opening. Each layer of ink may have a diffuse reflectivity that is matched to that of the black ink. A diffuser layer such as a polymer coating layer with light-scattering particles may be coated on the inner surface of the layer of ink in a sensor window opening.

Abstract: A glass member for a housing of an electronic device may include an aluminosilicate glass substrate defining a first surface of the glass member, the first surface having a first surface roughness, a fused composite coating bonded to a portion of the aluminosilicate glass substrate and defining a second surface of the glass member, the second surface having a second surface roughness greater than the first surface roughness, a first ion-exchanged layer extending into the glass member and through the fused composite coating, and a second ion-exchanged layer extending into the glass member from the first surface. The fused composite coating may include an amorphous glass matrix and a crystalline material dispersed in the amorphous glass matrix.

Abstract: An electronic device may have a display with a transparent layer such as a cover layer. An ambient light sensor may be aligned with an ambient light sensor window formed from an opening in a masking layer on the transparent layer in an inactive portion of the display. To help mask the ambient light sensor window from view, the ambient light sensor window may be provided with a black coating that matches the appearance of surrounding masking layer material while allowing light to reach the ambient light sensor. The black coating may include multiple pigments and may have a flat spectrum to enhance color ambient light measurements made with the ambient light sensor. The black coating may include a polymer binder or other binder that contains multiple pigments. The pigments may include a black pigment, a blue pigment, and an infrared-light-transparent pigment and/or other pigments.

Abstract: An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area without pixels. An opaque masking layer such as a layer of black ink may be formed on the underside of the display cover layer in the inactive area. Windows may be formed from openings in the opaque masking layer. Optical components such as infrared-light-based optical components may be aligned with the windows. The windows may include coatings in the openings that block visible light while transmitting infrared light. The window coatings may be formed from polymer layers containing pigments, polymer layers containing dyes that are coated with antireflection layers, thin-film interference filters formed from stacks of thin-film layers, or other coating structures.
