This paper presents an integral three-dimensional (3D) display that efficiently enhances both the pixel densities and viewing angles of 3D images with parallel projection of elemental images. In the proposed method, ultra-high-definition (UHD) elemental images are projected and superimposed as parallel light rays from densely arranged compact UHD projectors onto a lens array. Three-dimensional images with enhanced pixel densities and viewing angles can be displayed by optimizing the projector positions and system design. The prototype yielded a horizontal pixel density of 63.5 ppi, approximately 97,000 pixels, and a viewing angle of approximately 30°, making it superior to previous integral 3D display systems.
本文提出了一种整体式三维（3D）显示器，通过元素图像的平行投影有效地提高了3D图像的像素密度和视角。在所提出的方法中，超高清（UHD）元素图像从密集排列的紧凑型UHD投影仪作为平行光线投射并叠加到透镜阵列上。通过优化投影仪位置和系统设计，可以显示具有更高像素密度和视角的三维图像。该原型的水平像素密度为63.5 ppi，约97000像素，视角约为30°，优于以往的整体式3D显示系统。
