Abstract
The light control laminated film according to various embodiments of the present invention may include a louver film including a plurality of light absorption patterns arranged in parallel and a light transmitting portion surrounding at least a portion of the plurality of light absorption patterns, a reflective polarizing film configured to adjust the angle of light transmitted to the louver film for polarization recycling, and a first adhesive layer disposed between the louver film and the reflective polarizing film.
Claims14
A light control film comprising:
- a louver film including a plurality of light absorption patterns arranged in parallel and a light transmitting portion surrounding at least a portion of the plurality of light absorption patterns;
- a reflective polarizing film adjusting an angle of a light transmitted to the louver film;
- and
- a first adhesive layer disposed between the louver film and the reflective polarizing film,
- wherein a difference between a first refractive index of the light transmitting portion and a second refractive index of the plurality of light absorption patterns is 0.05 or more, and
- wherein the plurality of light absorption patterns include a first side and a second side formed asymmetrically with each other.
A backlight unit comprising:
- a light source;
- a light control film comprising a louver film including a plurality of light absorption patterns arranged in parallel and a light transmitting portion surrounding at least a portion of the plurality of light absorption patterns;
