Japan Display and NHK Media Technology demonstrate LCD-based light-field display

June 15, 2017 // By Julien Happich
Prior to SID's Display Week, Japan Display Inc. (JDI) and NHK Media Technology, a provider of broadcasting engineering and advanced media technologies announced their collaboration on the research and development of next-generation light field displays.

Through collaborative research, the two companies developed a 17.0-inch light field display based on an 8K LCD from JDI and relying on high-definition, next-generation 3D image processing from NHK Media Technology.

The light field display was then exhibited during Display Week. According to a recent report from Nikkei Technology, the 8k LCD panel featured a low-temperature polycrystalline Si (LTPS) TFT backplane and was run in In Plane Switching mode. Screen resolution and angle range reported for the 3D viewing experience were 176ppi and 130º, respectively.

Assuming a 7680×4320 resolution for the 17 inches diagonal 8K LCD, that makes roughly a 450ppi native resolution for the 2D display whose pixels must have been clustered in some manner under a micro-lenticular array film or nanogratings for the light field implementation (though JDI wouldn't reveal the trick they use).

Due to its nature, the 3D view can be experienced without any special glasses and from any position, just as in the real world. Check out the movie Japan Display made, showing the display from different angles.
