Embodiment
Consult Fig. 1 to shown in Figure 3, the present invention is a kind of light guide plate module, and it comprises:
One framework 10 has a spatial accommodation 11 and a medial surface 12 at least; One light guide plate 20 is to be located in this spatial accommodation 11, and this light guide plate 20 has one first side surface 21, one second side surface 22, one the 3rd side surface 23, one the 4th side surface 24 and an exiting surface 25 perpendicular to aforementioned each side surface at least; And has a light incidence section 211 on this first side surface 21;
At least one light absorption structure 30 is located at this second side surface 22, the 3rd side surface 23, the 4th side surface 24 on one of them at least; One light source 40 is to be located in the spatial accommodation 11 of this framework 10, and shines a light 41 with a pre-determined tilt angle θ towards this light incidence section 211; This light 41 is through this light incidence section 211 and at least towards this second side surface 22, the 3rd side surface 23,24 one of them irradiation of the 4th side surface; And when shining this light absorption structure 30, by these light absorption structure 30 absorptions (Fig. 4 A represents because each side surface of the light guide plate 20 at this light absorption structure 30 and place is a tight, does not have total reflection phenomenon so light 41 is absorbed by this light absorption structure 30); Alleviate the glistening intensity of the side surface at these light absorption structure 30 places whereby, and make this exiting surface 25 luminous with uniform brilliance.
Consult Fig. 2 and Fig. 3, when opening bright this light source 40, this light source 40 is with light incidence section 211 irradiation light 41 of pre-determined tilt angle θ towards this light guide plate 20, this light 41 is through this light incidence section 211 and towards this second side surface 22, the 3rd side surface 23, one of them the direction irradiation of the 4th side surface 24, as long as shine this second side surface 22, the 3rd side surface 23, one of them light 41 of the 4th side surface 24, will be absorbed by this light absorption structure 30, because tight between each side surface of the light guide plate 20 at this light absorption structure 30 and place, can be at this second side surface 22, the 3rd side surface 23, the 4th side surface 24 causes total reflection phenomenon on one of them, more can not shine the medial surface 12 of this framework 10 more certainly and forms reflective.

For making this exiting surface 25 luminous with more uniform briliancy, this light absorption structure 30 can be located on this second side surface 22, the 3rd side surface 23 and the 4th side surface 24 simultaneously, makes each side surface of this light guide plate 20 can not produce reflective phenomenon.
In fact, this light absorption structure 30 has a predetermined absorptivity.Certainly, this light absorption structure 30 also can be revised as by the different material of several absorptivities and be formed.Shown in Fig. 4 B, this light absorption structure 30 is made up of two different material 30A and 30B of absorptivity, the absorptivity of supposing this material 30A and 30B is respectively 30% and 50%, the extinction effect in the Z1 of first area relatively strong (promptly 30% and 50% is compound) then, and the extinction effect among the second area Z2 relatively weak (only 30%), in other words, where can design according to user's demand needs the local extinction of strengthening, but and then reaches elasticity adjustment and optimized purpose.
This light absorption structure 30 can be selected from unlike material printing ink, lacquer, adhesive tape, light absorping film at least one item wherein according to actual user demand, to adjust required absorptivity.
This light absorption structure can be soft material.
The present invention also can be used on the light guide plate of large-size according to brightness of illumination and the illumination intensity of LED.
In sum, the present invention is that each side surface (no matter long side surface or short side) in light guide plate all is provided with the light absorption structure, make light when shining each side surface of light guide plate, absorbed by the light absorption structure at once, alleviate the reflective phenomenon of light guide plate side surface, make its exiting surface briliancy quite even, even between this light guide plate and this framework be non-driving fit design, also can not influence the extinction effect of light absorption structure, and this light absorption structure can be selected from printing ink according to actual needs, lacquer, adhesive tape, wherein a kind of of light absorping film, to adjust required absorptivity, to reach the advantage that makes the briliancy homogeneity and be easy to adjust.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
