95‐1: Augmented Reality Display Based on Surface Relief Grating with Large Area Processing

AR display has been the most promising new technology in the current display market. Among which surface relief grating waveguide has the advantages of large field of view, small volume and light weight. This article adopts the large‐area (370 mm * 470 mm) waveguide prepraration route as a solution to the low‐cost and high‐efficiency waveguide route, showing excellent structural uniformity of more than 95%. The waveguide numbers is 5 to 10 times that of the conventional wafer‐level route, which can further promote the practical application of AR waveguides.
