Abstract
In this paper, we demonstrated the Inkjet print method to fabricate
a ultraviolet (UV)-curable epoxy microlens deflecting array with controllable
curvature and filling factor, by which a 7-in light guide plate with 82% uniformity
and 70% light efficiency was successfully implemented. The microlenses can
be directly formed by plastic discharged by inkjet head, eliminating the need
for molds and slashing development time. Proposed method will certainly has
a promising impact on rapid prototyping and other specialized microfeatures
due to its simplicity and versatility.
