3D images can be displayed through the reconstruction of light rays in various directions by displaying light source array images on an LCD panel for light-ray control.

Another problem is that the base of a 3D-printable hexagonal mirror array consisting of multiple hexagonal columns is so large that it cannot be created with a single output using a 3D printer.

A 3D display has been developed that uses a light source array *1 to electrically switch between 3D and 2D images according to the viewer’s preference, and it also adjusts images in real time ...
