Shulou(Shulou.com)11/24 Report--

CTOnews.com March 21, AAC AAC Technology announced that it has successfully developed a new generation of single-layer full-color optical waveguide lenses, laying a solid technical and mass production foundation for further layout of the AR market.

▲ AAC new generation of optical waveguide wafer samples it is reported that the traditional AR equipment with single-layer optical waveguide lenses is difficult to meet the display requirements of large viewing angle or high-quality color images, so the current market AR equipment mainly uses multilayer optical waveguide lenses, but multilayer optical waveguide lenses are not a perfect solution, because interlayer alignment tolerance and stray light reflection will lead to serious rainbow pattern and MTF reduction. It affects the imaging effect, that is, it has the defect of insufficient imaging quality of the optical waveguide lens.

The new generation of single-layer color waveguide lenses developed and manufactured by AAC technology have multiple advantages such as higher light efficiency, stronger resolution and better color uniformity, realizing the balance between the setting of single-layer optical waveguide lenses and large viewing angle and high picture quality. bring consumers a clearer picture and a more transparent and thin wearing experience.

CTOnews.com summarizes the following highlights:

Single-layer full-color: at present, color optical waveguides in the industry usually need 2 to 3 layers to realize. AAC Technology has broken through the bandwidth bottleneck of optical waveguides through unique high refractive index grating processing technology to achieve single-layer full-color.

Compatible with a variety of FOV: the optical waveguide developed by AAC Technology is compatible with 30 °50 degree FOV to meet the needs of different customers and application scenarios.

Further improvement of light efficiency: the unique design of AAC technology coupled with the grating significantly improves the coupling light efficiency, ensuring that more than 90% of the light can enter the optical waveguide. At the same time, the overall optical efficiency of the optical waveguide is ensured through the grating partition design of the extended region and the coupled region, and the overall optical efficiency of the lens color exceeds that of 310nits / lm.

Thinner and lighter: AAC monolayer color technology can further lighten the lens on the basis of improving the light transmittance. Compared with the common double-layer scheme on the market, the thickness and weight of AAC's new single-layer color optical waveguide lenses have been reduced by more than 50%, greatly increasing the comfort of users.

Better color uniformity: through the optimization and adjustment of the expanded region and the coupled region, AAC's new generation of single-layer color optical waveguide lenses have reached the color uniformity of consumer grade requirements.

Less light leakage: through the grating design, the light leakage from the outside of the optical waveguide coupling area is reduced and the privacy is protected.

Higher definition: higher definition (16lp / deg > 40%), allowing users to easily read the information presented by the device.

AAC Technology said that the company independently mastered the cutting, grinding, polishing, cleaning and other processes, has the core technology and mass production capacity to prepare glass wafers of various sizes, and is currently building a mass production line for single-layer full-color optical waveguide lenses.
