a Schematic diagram of the MLA for integral imaging. b Produce of MLA based on blade coating technique and curable liquid, where microlenses are tied to the well-confined surface. c The mechanism of selective wetting. The curable liquid NOA-73 is confined in the hydrophilic area. d Oxygen plasma modification process based on reactive ion etching. Oxygen plasma is adopted to modify the hydrophobic interface so as to selectively create a well-defined hydrophilic area, which provides strong restriction for the curable liquid by introducing chemical bonding force
