A compact near-eye display with a 60° horizontal field of view, wide eye box of 5 mm, and high resolution of 720 p is proposed and developed by combining a transmission hologram that duplicates the beam of a scanning display and a reflection hologram that reflects duplicated beams toward the user's eye. The feasibility of the proposed near-eye display is demonstrated by examining the specifications and exposure of 24 multiple holograms. A compact NED that can display images with a horizontal FOV of 60° and that has a 6.2 mm × 4.8 mm eye box and 720 pixels vertical resolution is achieved.
