On December 8, the 2023 Future Business Ecological Link Conference and the 8th Golden Gyro Award (hereinafter referred to as "FBEC 2023") came to an end at the Sheraton Shenzhen Greater China Hotel, and Lingxi Shimmer's "'True Side Projection' 2D Array Optical Waveguide 2D-L" optical module project won the Annual Excellent VR AR Optical Design Award.
It is reported that the Golden Gyro Award is one of the most professional and influential comprehensive awards in the field of pan-TMT in China, which was led by Gyro Technology.
Since its inception, the Golden Gyro Award has attracted nearly 10,000 entries and selected thousands of high-quality projects. This year is the eighth year of the Golden Gyro Award, which has set up three categories of awards: games, XR and e-sports, with a total of 30+ award categories.
2D-L is a new member of the latest two-dimensional pupil dilation series (2D series) launched by Lingxi Shimmer.
In terms of parameters, the 2D-L weighs only 85G, it adopts LCOS scheme with high-brightness display, the imaging picture supports 1280X720 resolution full-color display, thanks to the blessing of two-dimensional pupil expansion technology, its field of view reaches 34 ° and the optical volume is only 2cc, which is currently unattainable by most one-dimensional waveguides, its eye brightness can reach 2500nit, MTF 06. This means that there will be no brightness problems even when outdoors during the day.
2D-L is the first "true side-projection two-dimensional dilated pupil waveguide module". The primary pupil path of the traditional two-dimensional pupil expansion waveguide module is affected by the structural design, and the field of view is inevitably occluded. This makes the eyebox of the ** person limited to a certain range area, and once it is offset to one side, it will exceed the display boundary and enter the pupil expansion area.
The type of 2D-L is different from all the 2D pupil expansion waveguide products that can be seen on the market today. Thanks to the ability of Lingxi Shimmer to control the whole link of the optical waveguide module from optical design to lighting design to waveguide design, Lingxi Shimmer can be further optimized in the use of two-dimensional pupil expansion technology, which makes the 2D-L waveguide part can be reconstructed.
Corresponding to the traditional scheme, the "true two-dimensional pupil expansion waveguide module" after the reconstructed design will not obstruct the observation of the human eye at first, and the picture is transparent and the pupil expansion structure is further reduced, which makes the first line of sight will not be blocked within the reach of the human eye, which is very important for an AR product that needs to take into account the function of glasses in addition to the display screen.
In terms of display, Lingxi Shimmer has been innovatively combining the display source and projection source of the optical machine into one, which is equivalent to the optical device that reuses a part of the imaging optical path for illumination, and realizes the unified design of illumination imaging + waveguide imitation.
The advantage of this design is that the volume of the optical part is reduced by more than 1 2, and on this basis, the 2D-L is upgraded with the newly developed compact lighting collimation technology of Lingxi Shimmer, which improves the lighting efficiency by 4 times compared with the one-dimensional optical waveguide module, and the light energy utilization rate is also further improved. At the same time, through the structural redesign, the ultimate height of the optical and mechanical part is only 7mm.
2D-L carries the design concept of Lingxi Shimmer with the end in mind, and its form has been designed from the beginning to consider how to strive for more space for the integration of AR glasses in the future, and to compromise on the aesthetics of AR glasses as much as possible.
