KDH has collaborated with the Department of Electrical and Electronic Engineering at the University of Melbourne and the Melbourne Centre for Nanofabrication to develop a new optical waveguide technology called TIGER Display (Transparent Integrated Guiding Enhanced Reality Display). This technology utilizes high-transparency plastic film as a substrate and is produced through 3D printing, offering the advantages of easy mass production and lightweight compared to the previous use of glass materials. It provides a more viable solution for the AR industry. Additionally, the technology has the capability of integrated fabrication, allowing for the printing of prescription lenses and AR display functionality in a single device. This integrated design not only offers convenience but also makes AR glasses appear like regular eyewear, blending in and catering to the personalized needs of users.
After nearly two years of research and experimentation, KDH has successfully produced the world's first flexible waveguide lenses, aiming to achieve the most wearable augmented reality device. We have overcome design and process-related challenges, such as considering the impact of material physical properties on virtual image integrity, optical characteristics including refractive index and reflectivity of different materials, deformation during the formation of composite materials, refractive index compensation between materials, and control of surface microstructures. Ultimately, we have successfully created the world's first flexible waveguide lenses that are impact-resistant, less prone to breakage, and flexible. Designers can easily incorporate curved designs that seamlessly integrate with the appearance of end products.
This design concept is widely applied in near-field applications such as AR glasses, helmet visors, automotive HUDs, and more. It provides a comfortable fit that conforms seamlessly to the user's facial contours and head shape, while delivering exceptional durability.
