Backlight module
A backlight module includes a plurality of first light sources emitting first light and a light guide plate. The first light sources are arranged in a line and spaced from each other. Two adjacent first light sources define a first space therebetween. The light guide plate includes a first light incident surface and a light output surface. The first light incident surface has a plurality of bright areas respectively corresponding to the first light sources and a plurality of dark areas respectively corresponding to the first spaces. A plurality of first reflectors is disposed on the plurality of dark areas of the first incident surface. The light output surface is adjacent and perpendicular to the light incident surface.
1. A backlight module, comprising:
a plurality of first light sources being arranged in a line and spaced from each other, two adjacent first light sources defining a first space therebetween, the plurality of first light sources emitting first light; and
a light guide plate comprising:
a first light incident surface for receiving the first light from the plurality of first light sources, the first light incident surface having a plurality of bright areas respectively corresponding to the first light sources and a plurality of dark areas respectively corresponding to the first spaces, a plurality of first reflectors being disposed on the plurality of dark areas of the first incident surface; and
a light output surface being adjacent and perpendicular to the light incident surface;
wherein the light guide plate has a plurality of first dark regions therein, and a plurality of first micro-structures is formed in each of the plurality of first dark regions of the light guide plate; and
wherein a plurality of other micro-structures is formed in the light guide plate except the plurality of first dark regions thereof, and the plurality of first micro-structures has a greater density than the plurality of other micro-structures.
2. The backlight module of claim 1 further comprising a plurality of first diffusers, wherein the plurality of first diffusers is disposed on the plurality of first bright areas of the first incident surface.
3. The backlight module of claim 1 further comprising a reflecting layer, wherein the light guide plate further comprises an edge surface opposite to the first incident surface, the reflecting layer being disposed on the edge surface of the light guide plate.
4. The backlight module of claim 1 further comprising another reflector, wherein the light output surface has a mounting area adjacent and connected to the first light incident surface, the another reflector being disposed on the mounting area of the light output surface.
5. The backlight module of claim 1 further comprising a reflecting film, wherein the light guide plate further comprises a bottom surface opposite to the light output surface, the reflecting film being disposed on the bottom surface of the light guide plate.
6. The backlight module of claim 1 , wherein the plurality of first dark regions is adjacent to the plurality of dark areas of the first light incident surface.
