Flat Panel Visually-equivalent Light Field 3D Display

A novel autostereoscopic flat-panel three-dimensional (3D) display that can display viewpoint images directly and reproduce smooth horizontal motion parallax using a small number of directional images is introduced. Using the human perception characteristics of doubled images, we interpolate directional images and generate visually equivalent rays using optical linear blending in the display. Our previous proposal required a huge apparatus and had low image quality. Since this new display only requires a barrier, whose spacing is almost the same as the pixel width, to be added to a regular horizontal RGB (red-green-blue) stripe type 2D LCD (liquid crystal display), it yields thin flat panel displays. The lens-less optical configuration enables high image quality because it is intrinsically free from distortion and blur. Moreover we sorted out phenomena from the standpoint of spatial frequency and showed that perception can be explained optically only by assuming the cutoff frequency of the visual system.

Table Top Visually Equivalent Light Field 3D Display Using 15.6-inch 4K LCD Panel

A highly realistic table-top type light field three-dimensional (3D) display that offers horizontal parallax is proposed. With a 4K LCD (liquid crystal display) and parallax barrier, rays are interpolated directionally, and high resolution and smooth motion parallax are achieved. Since this interpolation works as anti-aliasing itself, small characters can be displayed stably in 3D space.
