Therefore, the integrated imaging 3D display has become one of the leading edge 3D display modes in the world at present, and is also one of the most promising modes for realizing naked eye true 3D display of the 3D television.

It may provide different 3D pictures in different viewing directions. However, the bottleneck problem of insufficient 3D resolution severely affects the viewer experience.

In addition, the conventional integrated imaging dual-view 3D display has the defects of low optical efficiency and the like.
