Abstract: In some examples, an apparatus may include a backlight unit (BLU) including an electronic integrated circuit layer, a photonic integrated circuit layer, a color conversion module, and a display interface layer. In some examples, a BLU may include at least one laser or may be configured to receive laser light from at least one external laser source. Laser light may be transmitted towards a portion of the display interface layer using the photonic integrated circuit. Color conversion modules may be used to convert the laser light into one or more desired colors. Example apparatus may be used in head-mounted devices such as augmented reality and/or virtual reality devices. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: An illumination system includes a micro-LED array having a plurality of individually addressable diodes, a concentrator array overlying an output of the micro-LED array and configured to decrease a numerical aperture of light emitted by the array, and a non-emissive display panel arranged to receive light from the concentrator array.

Abstract: A system uses a machine learning model trained using multitask learning for processing audio signals of different types. The system may be used in a device such as a headset, smart glasses, or a smart watch, and may be used to make predictions based on different types of audio signals, for example, for classifying acoustic events based on audio signal or for keyword spotting to detect wake words. The use of a single machine learning model for analyzing different types of audio signals improves storage efficiency as well as energy efficiency of devices compared to systems that use a different machine learning model for processing each type of audio signal.

Abstract: A display system may include a light source that emits input light having a wavelength within a source wavelength range and an array of color conversion units overlapping a display area. A first set of color conversion units of the array of color conversion units may include a first color conversion medium that converts the input light to a first color of light having a wavelength within a first wavelength range that is different than the source wavelength range. The display system may also include a waveguide having an out-coupler that directs the input light from the light source toward the array of color conversion units. Various other devices, systems, and methods are also disclosed.
