Japanese mobile giant NTT Docomo, through its subsidiary NTT Docomo Ventures, has invested in QD Laser for an undisclosed amount.
QD Laser – which was founded in 2006 as an offshoot of Fujitsu Ltd with funding from Mitsui Ventures – develops and manufactures semiconductor lasers, retinal scanning laser eyewear, and other products based on quantum dot laser technology.
By leveraging its nanocrystal technology, the Kanagawa-based firm achieved mass production of quantum dot lasers capable of operating stably even at high temperature.
In 2018, QD Laser applied its technology to incorporate a compact laser projector with extremely small output into a spectacle-type device, and commercialized what was claimed to be the world’s first retinal scanning laser eyewear that directly projects an image onto the user’s retina for image display.
The technology for projecting a direct image onto the retina using a laser does not require the user to focus their eyes to see an image, so it is expected to improve the quality of life of patients with ametropia or corneal opacity and weak-sighted individuals.
The technology can also be applied for realizing natural-looking augmented reality (AR) that people with normal vision can experience.
Docomo said it has high expectations for potentials of the retinal scanning laser eyewear developed by QD Laser for resolving various social issues and contribute to creating new services through AR.
