As noted by Tech-On!, Japan Display Inc. (JDI; Tokyo, Japan) exhibited an 8K light-field display at the Society for Information Display 2017 conference (SID 2017; May 21 to 26, 2017, Los Angeles, CA).

Light-field displays realize 3D viewing by reproducing image light traveling in a number of different directions (the number depends on the exact light-field configuration). They allow viewing of 3D images without the need for special glasses. And, unlike parallax-barrier glasses-free 3D displays, their images change in accordance with the viewing angle as do real objects. (Note: due to the optical configuration, a light-field display has a resolution that is lower than the actual number of pixels in the display.) Light-field technology is used by the Lytro camera to allow focusing of images after they are taken.

The light-field display exhibited by JDI has a back plane composed of low-temperature polycrystalline silicon (LTPS) TFT, and its LCD mode is IPS (in-plane switching). Its screen size, resolution, and angle range for 3D viewing are 17 in., 176 ppi, and 130°, respectively.

At SID 2017, Samsung Display also exhibited a light-field display. It uses a 5.09-in. OLED panel. Its 3D viewing angle range is 30°, and it supports 26 viewpoints. It is expected to be used for 3D picture books, gaming, head-mounted displays, and automotive displays.
