Single-Panel Complex Holographic Display with Three-Phase Covalent Macropixel

초록

A 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. A novel single-panel holographic display featuring ultralow noise and high efficiency is demonstrated. The essential idea of the proposed architecture is three-phase covalent macropixel, which is formed by the point-symmetric covalent concatenation of sub-pixels. The proposed single-panel holographic display exhibits three times signal efficiency enhancement and tens of times noise reduction performance in generating full-color computer-generated hologram images. image
