Background

Therefore, the integrated imaging 3D display has become one of the international leading edge 3D display modes at present, and is also the most promising naked-eye true 3D display mode for realizing 3D television.
In recent years, the integrated imaging 3D display and the dual view display are fused to form an integrated imaging dual view 3D display. It may provide different 3D pictures in different viewing directions. However, the bottleneck problem of insufficient 3D resolution seriously affects the experience of the viewer. In the traditional integrated imaging double-view 3D display, the number of 3D pixels in the vertical direction is too small, so that the viewing effect is further influenced, and the wide application of the integrated imaging double-view 3D display is restricted. In addition, the conventional integrated imaging dual-view 3D display has a problem of low optical efficiency.
