How do they get that SWAP down besides a 5mm waveguide? DPD maybe?

Gartner forecasts that “by 2022, the top-selling model of AR HMDs will weigh less than 50 grams with up to a 100-degree field of view horizontal, down by more than 50% from the average of more than 100 grams with a 45-degree field of view in 2018.... Waveguide optics for AR HMDs has recently brought more attention to and raised the profile of microdisplays. Well-designed waveguide optics is able to drastically reduce the weight of AR HMDs while simultaneously providing a wider field of view and enhanced picture quality.”
