Abstract: An electronic device may have an optical system that includes one or more light-based components. The light-based components may include light-emitting components such as light-emitting diodes or lasers and may include light-detecting components such as photodiodes or digital image sensors. The optical system may include a light diffuser. The light diffuser may diffuse light that is being detected by a light-detecting component or may diffuse light that is being emitted by a light-emitting component. Light diffusers in optical systems may be formed from patterned light diffuser layers on transparent substrates. Layers of sealant, thin glass layers, antireflection coatings, and other layers may be incorporated into the light diffusers. The light diffuser layers may operate at visible wavelengths and infrared wavelengths. An infrared light diffuser layer may be formed from a patterned silicon layer such as a patterned layer of hydrogenated amorphous silicon.

Abstract: An electronic device may have transparent members such as display cover layers and camera windows. A transparent member such as a sapphire member may be provided with an antireflection coating. The antireflection coating may have a stack of dielectric thin-film interference filter layers that form a thin-film interference filter that suppresses visible light reflections. The stack of dielectric thin-film interference filter layers may have thicknesses and materials that provide the thin-film interference filter and coating with low light reflection properties while enhancing scratch resistance. An adhesion layer may be used to help adhere the stack of thin-film interference filter layer to the transparent member. An antismudge coating such as a fluoropolymer coating may be used to reduce smudging. Graded layers and layers with elevated hardness values may be used in the coating.

Abstract: A portable electronic device has a device housing, and an electronic camera module in the device housing. The module has a focusing lens to focus light from a scene, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of the light from the scene to reach the imaging sensor. The electro-optic variable aperture may include a first aperture stack placed on a transparent substrate and a second aperture stack placed on the first aperture stack. The first aperture stack defines a first aperture and the second aperture stack defines a second aperture that is larger than the first aperture. Each aperture stack includes a transparent conductive oxide layer that is common with the adjacent aperture stack. Alternatively the electro-optic variable aperture may include an aperture stack that has two transparent conductive oxide layer layers, where one layer is in the form of concentric annuli.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes on a printed circuit board. The backlight unit may include first, second, and third light spreading layers formed over the array of light-emitting diodes. A color conversion layer may be formed over the first, second, and third light spreading layers. First and second brightness enhancement films may be formed over the color conversion layer.

Abstract: A display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. The output coupler may also transmit world light from real-world objects towards the eye box. A bias lens may pass the world light to the output coupler. An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.

Abstract: Configurations for a beam deflector metasurface are disclosed. The beam deflector metasurface may include beam deflectors arranged in a repeating, radial pattern of concentric zones. The beam deflector metasurface may be a large area, high numerical aperture metasurface optic with high efficiency when directing light at non-normal angles of incidence. The different concentric zones may direct received light in varying directions with various steepness of angles. The beam deflectors may include pillars that may be the same or different width, height, or shape. The pillars may function as diffractive gratings and the cross-coupling between the pillars may direct the output light. The zones of the beam deflector metasurface may allow for diffusing hot spots and spreading the light evenly over the target area. The beam deflector metasurface may be used for non-imaging applications where the deterioration of focus allows for better efficiency at non-normal input and output angles of incidence. The beam deflectors may be designed for polarization and wavelength sensitivity as well as allowing for multiple processing benefits such as patterning the beam deflectors onto active devices.

Abstract: An optical module includes a diffractive optical element (DOE) with a transparent conductive trace disposed over a surface of the DOE. An emitter is configured to direct a beam of optical radiation through the DOE. Control circuitry is coupled to measure a resistance of the transparent conductive trace and to control operation of the emitter responsively to the resistance.
