More Information
Summary:A waveguide (1000) configured to prop-agate light (1001)by total internal reflection, a display device, as well as a method and an apparatus for forming a waveguide are disclosed. The waveguide (1000) comprises a waveguide body (1100) comprising a first face (1110) and a second face (1120) opposite the first face (1110); and a coating (1200) on the first face (1110), the coating (1200) comprising an outer surface (1210) facing away from the first face (1110). The first face (1110) comprises a curved interface region (1111) between the waveguide body (1100) and the coating (1200), and the outer surface (1210) comprises a curved outer region (1211) opposite the interface region (1111). The outer region (1211) comprises a patterned region (1212), and the coating (1200) comprises on the outer surface (1210) a surface-relief structure (1220) defining the patterned region (1212).
