Abstract: An electronic device may include an infrared sensor with light sources and a quantum film photodetector. The light sources may emit short-wavelength infrared (SWIR) light through a display panel and the photodetector may receive the SWIR light through the panel after reflection off an object. The light sources and an integrated circuit may be mounted to a wall of a sensor module mounted to the panel. The module may include a lens. The photodetector may be disposed onto the rear wall, lens, integrated circuit, or display panel. The photodetector may include multiple types of quantum film to absorb different wavelengths of SWIR light. The SWIR light may pass through the display panel without distorting images emitted by the display panel. Using a quantum film in the photodetector may allow the photodetector to extend across a large surface area without unnecessarily increasing manufacturing cost for the device.

Abstract: An electronic device may include a first bias lens that transmits world light to an output coupler on a waveguide. The output coupler may transmit the world light while coupling image light out of the waveguide. A second bias lens may transmit the world light and the image light to an eye box. A tint layer may transmit the world light towards the output coupler. The tint layer may be planar and layered onto a planar surface of the first bias lens or another lens, may be separated from the first bias lens by an air gap, may be non-parallel relative to the waveguide, and/or may be curved and separated from the first bias lens and the waveguide by air gaps. When planar, the tint layer may be provided with spacers between substrates or between the tint layer and the waveguide to maximize parallelism.

Abstract: An electronic device may include a display with a waveguide that directs image light to an eye box using an output coupler. The display may include an electrically adjustable tint layer overlapping the output coupler. The tint layer may serve to maximize contrast of images in the image light. The tint layer may include a peripheral edge seal between first and second substrates and laterally surrounding an electrochromic gel. The peripheral edge seal may protect the gel from water and oxygen. The peripheral edge seal may include one or more rings of material and/or a glass ring spacer, the substrates may include cavities, and/or the gel may include spacer beads to help minimize warpage upon curing and thus maximize flatness of the tint layer. The electrochromic gel may include first and second redox species and a third redox species configured to tune a color response of the tint layer.

Abstract: A sensor stack is described. The sensor stack includes first and second electromagnetic radiation sensors. The first electromagnetic radiation sensor has a high quantum efficiency for converting a first range of electromagnetic radiation wavelengths into a first set of electrical signals. The second electromagnetic radiation sensor is positioned in a field of view of the first electromagnetic radiation sensor and has a high quantum efficiency for converting a second range of electromagnetic radiation wavelengths into a second set of electrical signals and a low quantum efficiency for converting the first range of electromagnetic radiation wavelengths into the second set of electrical signals. The first range of wavelengths does not overlap the second range of wavelengths, and the second electromagnetic radiation sensor is at least partially transmissive to the first range of electromagnetic radiation wavelengths.

Abstract: An electronic device includes a light-transmissive tint layer implemented on a light-transmissive viewing surface, on which a display panel is used to display augmented reality image content overlaid on background image content. A tint driver is used to apply electrical inputs to the light-transmissive tint layer to change optical properties of the light-transmissive tint layer. The temperature of the light-transmissive tint layer may be inferred from an electrical current applied to the light-transmissive tint layer. Dynamic values of the optical properties of the light-transmissive tint layer are predicted based on the electrical inputs and the temperature of the light-transmissive tint layer. The dynamic values of the optical properties are used to generate real-time compensated image data for the augmented reality image content.
