Electronic Devices with Low-Reflectance Coatings - A simplified explanation of the abstract
This abstract first appeared for US patent application 17746879 titled 'Electronic Devices with Low-Reflectance Coatings
Simplified Explanation
An electronic device is described that includes components emitting and detecting infrared light. The device may have optical modules presenting images to a user's left and right eyes. Each optical module includes an infrared light-emitting diode and an infrared camera. A low-reflectance coating is applied to prevent interference with the infrared components and user visibility. The coating is a low-visible-reflectance-and-low-infrared-reflectance coating made from carbon nanotubes and an organic solvent with zero polarity.

Original Abstract Submitted
An electronic device may include components that emit and detect infrared light. For example, a head-mounted device may have optical modules that present images to a user's left and right eyes. Each optical module may have an infrared light-emitting diode that emits infrared light that illuminates an eye box at an infrared wavelength, and an infrared camera that captures an image from the eye box at the infrared wavelength. A low-reflectance coating may be applied to one or more electronic device housing walls to prevent interference with the infrared components or with the visibility for a user. In particular, the low-reflectance coating may be a low-visible-reflectance-and-low-infrared-reflectance coating that exhibits low-reflectance across both visible and infrared wavelengths. The low-reflectance coating may be formed from carbon nanotubes and at least one organic solvent with zero polarity to ensure a low volatile organic component in the coating.
