Electronic Devices Having Quantum Film Infrared Sensors

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 li...

description 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.
