Abstract
The present invention discloses a backlight module and a liquid crystal display (LCD). A backlight module comprising an optical film, at least one light source, at least one reflecting housing and a reflecting surface. The reflecting surface and the optical film are symmetrically disposed with respect to the light source, and are disposed in identical side of the light source; the reflecting housing comprises a first reflecting layer and a second reflecting layer; the reflecting surface has a predetermined trajectory, and corresponds to the first reflecting layer and the light source. In the predetermined trajectory, the lights entering into the reflecting surface are reflected by the reflecting surface and enter into the optical film.

A backlight module, comprising:
- an optical film and at least one light source disposed at one side of the optical film;
- wherein the backlight module further comprises at least one reflecting housing and a reflecting surface;
- the reflecting surface and the optical film are symmetrically disposed with respect to the light source, and are disposed in identical side of the light source;
- wherein the reflecting housing is disposed between the reflecting surface and the optical film;
- the reflecting housing comprises a first reflecting layer to reflect the lights emitted from the light source to the reflecting surface, and a second reflecting layer to reflect the lights emitted from the light source to the optical film;
- and the first reflecting layer has a first arc shape and corresponds to a predetermined trajectory of the reflecting surface, so the lights reflected by the first reflecting layer are reflected into the reflecting surface;
- wherein the reflecting surface has the predetermined trajectory;
- the predetermined trajectory is a Non Uniform Rational B-Spline, and corresponds to the first reflecting layer and the first light source;
- in the predetermined trajectory, the lights entering into the reflecting surface are reflected by the reflecting surface and enter into the optical film.
