Abstract: Light-control panels including layered optical components are described in this application. An example of a light-control panel includes first and second glazing layers, first and second transitional layers extending between the first and second glazing layers that guide light emitted from a light source, and a third glazing layer extending between the first and second transitional layers through which light emitted from the light source is guided. The light-control panel also includes a light extraction layer extending between the third glazing layer and one of the first and second transitional layers that distributes light emitted from the light source. The first and second transitional layers have refractive indices that gradually decrease from a first value at surfaces proximate to the first and second glazing layers to a second value at surfaces proximate to the third glazing layer in the stack-up of the light-control panel.

Abstract: A system may have structure. The structures may include laminated structures formed by attaching inner and outer layers together with a layer of adhesive. The inner and outer layers in a structure may be formed from polymer such as polycarbonate. Forming the structure layers from polymer may allow the structure to have desired curvature. To improve safety and/or acoustic performance of the structure, the inner and outer structure layers may be formed from different materials. The outer polymer layer may be formed from polycarbonate and the inner polymer layer may be formed from a more brittle polymer such as polymethyl methacrylate (PMMA).

Abstract: A window may have a structural window layers such as an inner glass layer and an outer glass layer. The inner glass layer may be a layer of tempered glass. The outer glass layer may be a laminated glass layer. The inner and outer glass layers may be separated by an air gap. One or more reflection suppression layers such as antireflection layers and/or circular polarizers may be incorporated into the window to suppress reflections of light from within the interior region off of the window back towards the interior region. The antireflection layers may be formed on one or both surfaces of the inner glass and one or both surfaces of the outer glass. An electrically adjustable layer such as a guest-host liquid crystal light modulator layer or other electrically adjustable optical component layer may be interposed between the outer glass layer and the air gap.

Abstract: A vehicle or other system may have windows. A window may include an outer glass layer having a concave inner surface and an inner glass layer having a convex inner surface. Transparent conductive electrodes may be formed on the concave inner surface and the convex outer surface. A liquid crystal layer such as a nanocapsule guest-host liquid crystal layer may be interposed between the transparent conductive electrodes. During manufacturing, a first layer of liquid crystal may be coated onto the transparent electrode on the outer glass layer, and a second layer of liquid crystal may be coated onto the transparent electrode on the inner glass layer. The two coated glass layers may then be pressed together in a vacuum chamber so that the first and second liquid crystal layers merge and become a homogenous layer, thereby removing surface irregularities in the liquid crystal layers and reducing undesired haze.

Abstract: A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region.

The adjustable light transmission layer may have a polymer matrix layer with embedded guest-host liquid crystal cells. Each cell may have liquid crystal material and dichroic dye. The adjustable light transmission layer may be operated in a dark state to prevent light from passing through the window, a clear state in which the window passes light, and intermediate states that exhibit intermediate light transmission levels.

The outer window layer may have a molded concave surface formed by molding a second glass plate against a mold with a convex surface. The outer window layer may have an opposing non-molded surface that is not contacted by the mold during molding operations and is smoother than molded convex surface. A layer of polymer may join the inner and outer window layers with their molded surfaces facing each other.

Abstract: A light guide may be embedded in a window. The light guide may have cladding and a light guide core layer embedded in the cladding. The light guide core layer may include a polymer layer configured to receive light from a light source. A selective area adjustable haze layer in the light guide core layer may have segmented transparent electrodes that can be controlled to cause one or more selected areas of the adjustable haze layer to become hazy. Light from the light source may be guided across the window within the light guide core layer in accordance with the principal of total internal reflection. When a dynamically adjusted hazy portion of the selective area adjustable haze layer is reached by the guided light, the guided light will be scattered out of the light guide.

Abstract: A system may have windows. Each window may have inner and outer glass layers laminated together with polymer. Optical component layers may be incorporated into the polymer or the polymer may be free of embedded components. To avoid mismatch between adjacent window edges in systems with multiple adjacent windows, adjacent windows may be formed from shared-cut-edge-matched window panel sections that are cut from a common window panel. Windows may be formed from a single portion of laminated glass or may be formed by joining multiple smaller pieces of laminated glass together along a seam.

Abstract: A system may have windows. Each window may have light guide structures. The light guide structures may be formed between inner and outer glass layers. Light sources may emit light into the light guide structures. The light guide structures may include light guide core layers that guide light from the light sources across the window. Light-scattering structures may be provided to extract light from the light guide core layers. Some of the guided light may be extracted inwardly to serve as interior illumination for the system. Some of the guided light may be extracted outwardly. The outwardly extracted light visually obscures the interior region from the outside of the system, thereby providing system occupants with privacy.

Abstract: A transparent structure may have structural layers such as an inner layer and an outer layer, which may be formed from glass. The transparent structure may be curved. At least one of the inner layer and the outer layer may be coated with an infrared reflection coating. The infrared reflection coating may be formed from multiple optical resonators. Each of the resonators may include two half-mirrors separated by a dielectric layer. The half-mirrors may include infrared reflective material, such as silver. At least some of the resonators may additionally include a getter layer. The getter layer may be formed from amorphous material, nanoparticles in dielectric material, or other desired material, and may protect the infrared reflective material while the infrared reflection coating is being deposited. Additionally, the getter layer may reduce the color shift exhibited by high angle light as it passes through the transparent structure.

Abstract: A system may have windows. A window may have a structural window layer such as a structural window layer formed from laminated glass layers. The window may separate an exterior region from an interior region within the vehicle. A light guide illuminator in the window may provide illumination for the interior region. The light guide illuminator may have a light guide that receives light from a light source. The light guide may have a density of light scattering structures that increases as a function of increasing distance from the light source so that the interior illumination is uniform across the light guide illuminator. An adjustable optical component layer such as a light modulator and/or a haze compensation layer with a density of light scattering structures that decreases as a function of distance from the light source may be interposed between the light guide and the structural window layer.
