  • INCREASED REFLECTANCE IN TOTAL INTERNAL REFLECTION-BASED IMAGE DISPLAYS
    Publication number: 20180364543
    Abstract: Brightness in conventional total internal reflection image displays may decrease due to incident light passing through the dark pupil region in the white state. Adding sub-wavelength structures to the surface of the convex protrusions on the transparent front sheet may increase brightness in the white state. Control of the size, spacing, shape and refractive index of the sub-wavelength structures may lead to zeroth order reflection and enhanced brightness.
