Augmented Reality (AR) is generally considered as the next generation computing platform after PC and smart phones, with extensive applications and colossal market capacity. As the most essential hardware of AR wearables, the Near‐Eye Display (NED) system determines the final pattern of the product. In this paper, the NED solutions of mainstream AR eyewares are discussed, and the advantages and disadvantages of prism, freeform, arrayed waveguide and grating waveguide, the four popular technologies in NED of AR, are compared. Based on above information, the strengths of grating waveguide in AR products are analyzed, the principles and processing technology are introduced, and the prospect of grating waveguide to be the future of NED in AR is proposed.
