Fig. 1 is refer to, the structural representation of the BLU provided it illustrates one exemplary embodiment of the disclosure, such as Fig. 1 institutes Show, the BLU includes LGP110, light-emitting area towards the n light source 120 of the setting of default side 111 of LGP110 and for accommodating LGP110 and the n plastic frame of light source 120 130, n is the positive integer more than or equal to 2.Wherein：
Each light source in n light source 120 is used to send horizon light, and LGP110 is used for the horizon light for sending each light source Be converted to the two-way cross light propagated towards both sides.After each light source 120 sends horizon light, LGP120 changes horizon light It is perpendicular light source, needs that horizon light is converted into cross light first in conversion, and then realize the effect of mixed light.Alternatively, light source 120 can be LED, CCFL (Cold Cathode Fluorescent Lamp, cold-cathode fluorescence lamp) or EL (electroluminescent, electroluminescent), the present embodiment is not limited the type of light source, also, following except special Illustrate outer, illustrated for LED with light source 120.
Mirror surface 132 is provided with each frame 131 of default side 111 in plastic frame 130, each reflection Cross light is reflected back LGP110 by the cross light all the way that minute surface 132 is used to receive by the predeterminable area in frame 131, in advance If region is between the irradiated region of cross light in frame and default side 111.
In sum, the BLU that the present embodiment is provided, sets by plastic frame in each frame of default side Mirror surface is equipped with, the cross light that will be received by the mirror surface is reflected back LGP so that be reflected back the intersection luminous energy of LGP It is enough to intersect with the cross light in edge that LGP sends, to the cross light light filling at edge；In solving correlation technique, LGP's Edge occurs the problem of dark space；Having reached can be to the cross light light filling at edge, it is to avoid the effect of dark space occurs in fringe region.
Simultaneously as only needing to set the i.e. achievable light filling of mirror surface in the frame of plastic frame, having reached to save The effect of human-saving and material resources.
In the above-described embodiments, mirror surface 132 can include Part I 132a and Part II 132b, Part I 132a includes the part corresponding to irradiated region in frame 131, and Part II 132b is including corresponding to predeterminable area in frame 131 Part.
The cross light that Part I 132a is used to receive reflexes to Part II 132b.In LGP110 by light source 120 The horizon light for sending is converted to after cross light, and the cross light in LGP110 sides can be exposed to along optical path direction and is in Irradiated region in the plastic frame 130 of LGP110 peripheries, and the mirror surface of Part I 132a is provided with the irradiated region, because This, Part I 132a is received after the cross light, can be reflected the cross light that receives and be reflexed to second Divide 132b.
Alternatively, Fig. 2 is refer to, Part I 132a can be zigzag minute surface, and the zigzag is exposed in cross light After the surface of minute surface, the cross light that the surface will receive reflexes to Part II 132b.When actually realizing, in order to ensure by The cross light for receiving reflexes to Part II 132b, and Part I 132a can possess certain radian, than as shown in Figure 2 Radian.The present embodiment is not limited the radian, and its principle for following is that the cross light that will can be received reflexes to second Part 132b.
Alternatively, the height and angle of sawtooth can be set according to actually used demand, and the present embodiment is not limited this It is fixed.Wherein, the height of crown refers to the height between the extreme higher position and bottom of sawtooth mesostyle, and the angle of sawtooth refers to sawtooth Waist and base between angle.
Fig. 3 is refer to, after receiving cross light it illustrates Part I 132a, to the schematic diagram of cross light reflection.
Part II 132b is used to for the cross light that Part I 132a is reflected back to reflex to LGP110.
After the cross light that Part I 132a will be received reflexes to Part II 132b, Part II 132b can be with The cross light of reflection is received accordingly, and the cross light that will be received continues to reflex to LGP110.Alternatively, due to second It is the part in frame 131 between irradiated region and default side 111 to divide 132b to be in predeterminable area, and predeterminable area, therefore, After Part II 132b is reflected cross light, the cross light into LGP110 can intersect with the cross light of LGP110 conversions, And then the cross light to edge carries out light filling.
Alternatively, Fig. 2 is refer to, Part II 132b can be arcuation minute surface.The arcuation minute surface can be towards any Direction bends, and radian of its bending can be set according to actually used demand, and its principle for following is for receiving The cross light of a part of 132a reflections reflexes to LGP110.When actually realizing, in order to reduce plastic frame 130 seal ring thickness and then The design of narrow frame is realized, Part II 132b can bend to the direction away from LGP110, such as, as shown in Figure 2 is curved Qu Fangxiang is bent, and the present embodiment is not limited this.
In the structure shown in Fig. 2, Fig. 4 is refer to, after sending cross light it illustrates LGP110, cross light is by The reflection of a part of 132a and Part II 132b is eventually returned to the light path schematic diagram of LGP110.
Alternatively, Fig. 5 is refer to, Part II 132b can also be zigzag minute surface, and the present embodiment is to zigzag mirror The height and angle of the sawtooth in face are not limited, and its principle for following is the friendship of the Part I 132a reflections that will be received Fork light reflexes to LGP110.
It is above-mentioned only to come for example, alternatively by said structure of Part I 132a and Part II 132b, first 132a and Part II 132b is divided to be other structures, such as, Part I 132a can also be arcuation minute surface, and it is followed Principle be, the cross light that Part I 132a can send LGP110 reflexes to Part II 132b, Part II The cross light that Part I 132a reflects can be reflexed to LGP110 by 132b, and the present embodiment is not limited its practical structures It is fixed.
It is above-mentioned only to have one with default side, namely n light sources 120 are in as a example by the side of LGP, when actually realizing, aobvious When display screen is larger, in order to ensure the brightness of whole display screen, default side can also include first side parallel to each other and the Dual side-edge, for this kind of situation, can include n1 light source of the light-emitting area towards first side, and light-emitting area direction in BLU The light source of the n2 of second side, such as, refer to Fig. 6, it illustrates the structural representation of now BLU.Wherein, n1 and n2 are big Can be with identical or difference in the value of the positive integer equal to 2, and n1 and n2.Also, frame corresponding to every side sets Meter is similar with above-mentioned described design, and the present embodiment will not be repeated here.
When actually realizing, first side and second side can be upper and lower side frame or left and right side frame in LGP110, this Embodiment is not limited this.
Disclosure another exemplary embodiment additionally provides a kind of LCM, and the LCM includes the BLU shown in Fig. 1.
