摘要：
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 degrees (-42 degrees similar to 66 degrees). We also have,fabricated Ni-stamper with the microlens array pattern for injection molding, one of the cost-efficient methods for mass production.
