Third surface 3, the third surface 3 are light energy incident side；

4th surface 4, the 4th surface 4 are light refraction layer, and it is multiple convex to be that diameter is irregular, the depth is consistent The laser site gone out；With

5th surface 5；

Wherein, the 5th surface 5 is located at the bottom surface of the light guide plate, the 4th surface 4 and the 5th surface 5 Adjacent, the first surface 1 is adjacent with the 4th surface 4, and the second surface 2 is located at the top surface of the light guide plate, institute State the side that third surface 3 is located at the light guide plate.

Preferably, it is hemispherical that the first surface 1, which has the laser site of multiple protrusions, laser site peak, Shape.

It is highly preferred that the laser dot size about 0.06*0.008mm.

Preferably, the second surface 2 is that frosting processes ridge orientation, and it is parallel to enter light direction with light source；Or described Two surfaces 2 are common minute surface.

Preferably, the third surface 3 is the surface with V-shaped groove；It can spaced point energy of light source, be conducive to surface Evenly.

Preferably, the 4th surface 4 is the laser site for multiple protrusions that diameter is irregular, the depth is consistent, with It is vertical that light source enters light direction.

Preferably, the 5th surface 5 is external reflection piece.

The beneficial effects of the utility model：

The utility model is using site layer, frosted layer light guide plate composite design, when the irregular laser structure site of convex-concave, Irregular laser site constitutes the straight trough that a plurality of edge is formed perpendicular to the direction of the plane of incidence, thus light by multiple duckpins suitably Aggregation and reflection, refraction, therefore brightness can be increased and promote that the space of a whole page is uniform, and dotted line interlocks, the intensive reflection of dot is had effectively achieved, So that light guide plate leaded light is evenly, evenness higher, and show more stable.

In addition, being provided with ball-type structure outstanding in first surface, excuse me reflecting surface, can be with by light bounces back to top The light-emitting surface for effectively promoting light toward light guide plate projects, and increases the brightness of light guide plate, promotes the uniformity of the space of a whole page, and its construction letter It is single and light conducting direction is clear, it is easy to emulate in advance and layout, is relatively easy to control cost and quality.
