Abstract
AbstractA single‐panel complex holographic display with a three‐phase covalent macropixel featuring ultralow noise and high‐efficiency 3D image generation is proposed. The essential feature of the proposed three‐phase covalent macropixel is the point‐symmetric covalent concatenation of sub‐pixels and an adaptive computer‐generated hologram encoding algorithm. The proposed single‐panel holographic display exhibits three times signal efficiency enhancement, 1/38 reduction of DC noise, and 1/50 reduction of conjugate noise compared to conventional holographic displays in the generation of full‐color computer‐generated hologram images. This noise reduction leads to three times the optical efficiency enhancement of holographic displays.
