Large-scale microlens arrays on flexible substrate with improved numerical aperture for curved integral imaging 3D display

摘要

Morphology of MLAs with inverted reflowing manner. ( ) 3D perspective images of a typical solidified microlens with inverted reflowing time of 1 h. ( ) The profiles of MLAs with respect to reflowing time. ( ) The evolution of NA and radius of MLAs with the reflowing time. The height profiles (red solid line) taken along the equatorial plane of a typical microlens and fitting of an ideal surface to the lens profiles (Red dash line) with inverted reflowing time of 1 min ( ) and 1 h ( ).
