QD Laser has succeeded in developing an innovative new retinal scanning laser eyewear by utilizing QD Laser’s
proprietary retinal scanning projection technology. We have realized very inexpensive and miniaturized laser eyewear
by combining our proprietary optical technology named VISIRIUM® technology with existing pico-projectors, At
the Laser World of Photonics 2019 (Munich, Germany, June 24-27, 2019), two prototypes will be exhibited anddemoed.

Background

QD Laser has developed a laser retinal scanning technology named "VISIRIUM® Technology" that draws images
directly onto the retina. This technology is based on the combination of laser and optical technology developed since
its founding, combining weak light from a three-primary-color laser light source with a minute mirror (MEMS mirror)
oscillating at high speed.
Launched in 2018, the "RETISSA® Display" is a head mounted display that is the first product of thecommercialization of this "VISIRIUM® technology". Since its release, it has provided a new vision through Redefining the Vision TM.
By diverting the existing pico-projector product and the pico-projector built-in smartphone as an image projectionengine, the newly developed optical attachment enables safe and wide viewing angle retinal projection. By combining
simple optics and commoditized projection devices, the devices offer lower cost, smaller size, and improved
convenience.

Two prototypes to be unveiled this time

1. Retissa Handy (Figure 1)
By combining a commercially available pico-projector with a unique Maxwell optics system, you can view a highresolution retinal projection image in a hand-held size as shown in Figure 1. The free focus feature allows you toenjoy an image with a horizontal viewing angle of 40 degrees naturally regardless of the focusing ability.
As a new initiative, RETISSA® Handy has been used to train Uran Sawada, a member of the Japan Para AthleticFederation.
2. Retissa Flex Periscope (Figure 2)
The combination of a small projector and an image-propagating optical system with a unique flexible structure
enables a retinal projection display to be realized with the glasses in place without interfering with ordinary correctiveglasses. The unique image propagation optics developed this time allows the size of parts around the eye to beminimized because there is no electrical circuit around the eyes. As with Retissa Handy above, the image quality
does not depend on the user's vision due to the free focus feature. It is a technology that plays a role like an earphone
in pico-projectors or smartphones with built-in pico-projectors.

OutlookThe superior portability and cost reduction features of the newly developed RETISSA® Handy and RETISSA® FlexPeriscope make it easier for anyone to use a retinal scanning laser display. In the future, we plan to develop newfeatures such as ultra-small and inexpensive perimeters, early detection of eye disease, self-examination of eye,
peripheral vision training, and integration with smartphone applications and smartphone functions.
Starting from this exhibition, we will gather opinions and requests from various angles, and we will complete theproducts that are truly required by the market, in terms of cost, function, and design. In addition, we aim at wide
spread of retinal scanning projection technology as application product of existing pico-projection, and we will seekbusiness partners in various forms.

QD Laser, Inc.

QD Laser, Inc. was established as a spin-off venture from Fujitsu Ltd. (Head office: Minato-ku, Tokyo; President:Tatsuya Tanaka; hereinafter, Fujitsu) in April 2006, with the investment of Fujitsu and Mitsui & Co. GlobalInvestment (former MVC) under Mitsui & Co., Ltd. (Head office: Chiyoda-ku, Tokyo; President: Tatsuo Yasunaga).
Based on the joint development of Fujitsu Laboratories Ltd. (Head office: Kawasaki City, Kanagawa Prefecture,President: Hidenori Furuta) and the University of Tokyo by over 10 years of industry-academia collaboration, QD
laser develops, manufactures and sells high-performance semiconductor lasers including quantum dot lasers fromvisible to 1300 nm in wavelength. The corporate statement “Through light, the world is evolving” symbolizes ourwill to contribute to society through laser and optical technologies.
We have continued development of for retinal scanning laser eyewear technology including a support for a clean
device society implementation promotion project by the National Research and Development Corporation New
Energy and Industrial Technology Development Organization (NEDO), and a support tool for practical applicationof welfare tool for FY2015. In 2018, we launched the world's first sales of RETISSA® Display, a consumer retina
scanning laser eyewear.
