Abstract
The utility model relates to the technical field of 3D displays, in particular to a light guide plate structure for improving the side light leak of a 3D display backlight module. The light guide plate structure comprises a luminous source and a light guide plate, wherein a positioning groove is arranged at the side edge of the light guide plate, and the side plate of the positioning groove has certain radian so as to reflect light emitted by the luminous source far away from the effective luminous region of the backlight module. In the utility model, the light emitting angle of the positioning groove on the side edge of the light guide plate is changed to adjust the direction of reflected light, so that the reflected light travels towards the non-effective luminous region (plastic box edge or outer side) of the backlight module, and the bright line spraying problem of the luminous surface is effectively improved.
Description
Technical field
The utility model relates to 3D display technology field, specifically, relates to a kind of light conducting plate structure that is used to improve 3D display backlight module side light leakage.
Background technology
Light reflected back module light-emitting area backlight zone, because the 3D display need adopt the micro-structural LGP, and it is thinner to mould the edge edge, is prone to cause the side bright line to spray, and makes distribution of light inhomogeneous, influences whole visual effect easily for the LGP detent.
When the angle of LGP detent C angle and light emitting source incident light was as shown in Figure 1, the incident light of light emitting source projected place, C angle, and the light that is reflected gets into the effective light-emitting area of module backlight zone, causes bright line to spray; When the angle of the straight angle of LGP detent and light emitting source incident light was as shown in Figure 2, the incident light of light emitting source projected straight angle place, and the light that is reflected gets into the effective light-emitting area of module backlight zone, causes bright line to spray, and whole vision is inhomogeneous.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of light conducting plate structure that is used to improve 3D display backlight module side light leakage is provided, and it can effectively improve the injection of side bright line, makes distribution of light even, and whole visual effect is preferable.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of light conducting plate structure that is used to improve 3D display backlight module side light leakage; Comprise light emitting source and LGP; Said LGP side is provided with detent, and the side radian of said detent is penetrated light emitting source the light that comes and reflected towards the direction away from the effective light-emitting zone of module backlight.
Further, the side radian of said detent is a C shape.
Further, the side radian of said detent is a S shape.
Further, the surface of said LGP between light emitting source and detent is rough surface.
Further, said rough surface is the sandblast structure.
Compared with prior art, the beneficial effect of the utility model is:
The utility model changes the angle of LGP side detent bright dipping, and adjustment reverberation direction makes reverberation advance towards the non-effective light-emitting zone of module backlight (moulding the edge edge or the outside), effectively improves the light-emitting area bright line and sprays problem.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is an existing LGP detent C angle index path;
Fig. 2 is existing LGP detent straight angle index path;
Fig. 3 is the utility model detent C shape side radian index path;
Fig. 4 is the utility model detent S shape side radian index path;
Fig. 5 is that the surface of the utility model LGP between light emitting source and detent is the index path of rough surface.
Among the figure, 1---light emitting source;
2---LGP;
3---detent;
4---the effective light-emitting zone of module backlight.
The specific embodiment
Embodiment 1:
As shown in Figure 3; The described a kind of light conducting plate structure that is used to improve 3D display backlight module side light leakage of the utility model; Comprise light emitting source 1 and LGP 2; LGP 2 sides are provided with detent 3, and the side radian of detent 3 is a C shape, light emitting source 1 are penetrated the light that comes and are reflected towards the direction away from the effective light-emitting zone 4 of module backlight.
Embodiment 2:
Present embodiment and embodiment 1 are roughly the same, and something in common repeats no more, and its difference is:
Consult Fig. 4, the side radian of detent 3 is a S shape, and it also can be penetrated the light that comes with light emitting source 1 and reflect towards the direction away from the effective light-emitting zone 4 of module backlight.
Embodiment 3:
Present embodiment and embodiment 1 are roughly the same, and something in common repeats no more, and its difference is:
The surface of LGP 2 between light emitting source 1 and detent 3 is rough surface; Through processed to LGP 2, adopt the sandblast structure, change LGP 2 plane roughness; Make light in this micro-structural plane domain generation scattering phenomenon; The homogenising radiation direction avoids the incident light concentration of energy at groove, improves the high light bright line and sprays.
The utility model is not limited to above-mentioned embodiment; If the various changes of the utility model or distortion are not broken away from the spirit and the scope of the utility model; If these changes and distortion belong within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and distortion.
