Abstract：

Curved　integral　imaging　3D　display　could　provide　enhanced　3D　sense　of　immersion　and　wider　viewing　angle,　and　is　gaining　increasing　interest　among　discerning　users.　In　this　work,　large　scale　microlens　arrays　(MLAs)　on　flexible　PMMA　substrate　were　achieved　based　on　screen　printing　method.　Meanwhile,　an　inverted　reflowing　configuration　as　well　as　optimization　of　UV　resin’s　viscosity　and　substrate’s　surface　wettability　were　implemented　to　improved　the　numerical　aperture　(NA)　of　microlenses.　The　results　showed　that　the　NA　values　of　MLAs　could　be　increased　effectively　by　adopting　inverted　reflowing　manner　with　appropriate　reflowing　time.　With　decreasing　the　substrate’s　wettability,　the　NA　values　could　be　increased　from　0.036　to　0.096,　when　the　UV　resin　contact　angles　increased　from　60.1°　to　88.7°.　For　demonstration,　the　fabricated　MLAs　was　combined　to　a　curved　2D　monitor　to　realize　a　31-inch　curved　integral　imaging　3D　display　system,　exhibiting　wider　viewing　angle　than　flat　integral　imaging　3D　display　system.　©　2020,　The　Author(s).
