Abstract

Abstract In this paper, we have proposed a novel LCD backlight unit (BLU) composed of a light‐guide plate (LGP) mounting high fill‐factor microlens array and an optical sheet of conical microlens array with a slanted angle of 54.5°. The proposed BLU shows 13.6% improvement in the total luminance compared with the conventional BLU and the viewing angle of 108° (−42° ∼ 66°). We also have fabricated Ni‐stamper with the microlens array pattern for injection molding, one of the cost‐efficient methods for mass production.
