Abstract
Disclosed in an embodiment of the present disclosure is a preparation method of a micro-cup substrate and a display device thereof, involving the electrophoretic display field, simplifying the process and reducing the cost. The micro-cup substrate preparation method comprises assembling together a bottom substrate and a surface-hydrophilized cover to form a substrate cell; pouring into the substrate cell a solution dissolved with UV-polymerizable monomer(s) and photoinitiator; UV-irradiating the substrate cell through a patterned photomask plate to allow the UV polymerizable monomer(s) in the translucent region to be subject to UV cross-linking polymerization, thereby enabling the bottom substrate to form a micro-cup substrate with a micro-cup structure, and removing the cover and the solvent to obtain the micro-cup substrate.
