Researchers develop full-color night vision goggles using a dual-emitter OLED upconverter device

Researchers from the Beijing Institute of Technology (BIT) have developed an infrared-to-visible upconversion device (night goggles) that stacks a mercury telluride (HgTe) colloidal quantum dot photodetector directly underneath a dual-emissive-layer OLED. Unlike previous upconverters, which output a single color and encode the infrared signal only as brightness, this device changes both its emitted color and its luminance depending on the wavelength and intensity of the incoming infrared light - effectively giving the wearer full-color infrared vision.
