摘要： A backlight module includes a light source, a light guide plate for guiding light from the light source, and a brightness enhancement film having a plurality of spherical surface microlenses for gathering light from the light guide plate. In contrast to traditional prism sheets, the brightness enhancement film having the plurality of spherical surface microlenses have better efficiency of light-gathering.
