A talk from the XR Enablement Track at AWE USA 2019 - the World's #1 XR Conference & Expo in Santa Clara, California May 29-31, 2019. Antti Sunnari (Dispelix Ltd): Full-color, single-waveguide near-eye displays for AR glasses and MR headsets For years, many have tried to develop a see-through, near-eye display technology that combines beautiful design, excellent image quality and scalable mass production with high yields. At Dispelix, we’ve figured it out. Dispelix is helping product companies to create beautiful AR glasses based on single-waveguide full-color displays with superior image quality and mass manufacturability. https://awexr.com

10. § Cost
§ Form factor
§ Image quality
§ Volume compatibility
A single layer – why?

11. Cost – wafer utilization and yield
66% 76% 87%
*Assuming 98% production yield in each process step for one layer

12. Form factor – display thickness
3.1mm 2.2 mm 1.3 mm
*Waveguide 800μm, protective glass 400μm, air gap 100μm

13. Volume compatibility – less is more
0.33M 0.5M 1M
*Assuming 1M annual waveguide production capacity and 100% yield

14. Image quality – MTF challenge

21. Diffractive waveguide displays are product-ready
§ Display form factor enables appealing
consumer products
§ Image quality enables professional and
consumer use
§ Diffractive waveguide displays can be
manufactures for mass market products
§ To open the market, ultra-small high
performance projectors are needed
