Abstract
The utility model discloses a kind of pyramid shape light guide plate mesh point structures, on the plate body of light guide plate, the lattice point structure is irregular pyramid shape slot, its four seamed edges are respectively the first seamed edge, the second seamed edge, third seamed edge and the 4th seamed edge, the length of four seamed edges is respectively L1, L2, L3, L4, and L1 < L3 < L2=L4, wherein the first seamed edge and third seamed edge, in same vertical plane, the second seamed edge and the 4th seamed edge are in same vertical plane.The utility model can effectively change the angle that anaclasis goes out light guide plate using irregular rectangular pyramid lattice point structure, so that vertically increasing with the amount of light of light guide plate, to promote overall brightness.
Description
Technical field
The utility model belongs to light guide plate technical field more particularly to a kind of pyramid shape light guide plate mesh point in crescent
Structure.
Background technique
Light guide plate is the site by being distributed thereon, and the light diffusion that light source is emitted is allowed to be evenly distributed on various letters
On the backlight module of breath and communication electronics product；The shape of site is for the diffusion of the light and the known light guide plate
Whether uniformly light-emitting has close relevance.Site on prior art light guide plate is generally circular in cross section or oval, same to lead
Site size on tabula rasa in the parallel direction with light source be it is identical, lead to the brightness irregularities of backlight module, light guide plate
Luminance is small, is not able to satisfy the requirement of light efficiency promotion.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of pyramid shape light guide plate mesh point knot
Structure can effectively change the angle that anaclasis goes out light guide plate using irregular rectangular pyramid lattice point structure, so that vertically and light guide plate
Amount of light increase, to promote overall brightness.
To achieve the above object, the utility model proposes following technical solutions: a kind of pyramid shape light guide plate mesh point structure,
On the plate body of light guide plate, which is irregular pyramid shape slot, and four seamed edges are respectively the first seamed edge, second
Seamed edge, third seamed edge and the 4th seamed edge, the length of four seamed edges are respectively L1, L2, L3, L4, and L1 < L3 < L2=L4, wherein
First seamed edge and third seamed edge are in same vertical plane, and the second seamed edge and the 4th seamed edge are in same vertical plane.
Preferably, first seamed edge and the angle of central axes are 49 °.
Preferably, the third seamed edge and the angle of central axes are 67 °.
Preferably, second seamed edge and the 4th seamed edge and the angle of central axes are 70 °.
Compared with prior art, the revealed a kind of pyramid shape light guide plate mesh point structure of the utility model has as follows
The utility model has the advantages that can effectively change the angle that anaclasis goes out light guide plate using irregular rectangular pyramid lattice point structure so that vertically with
The amount of light of light guide plate increases, to promote overall brightness.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the utility model site transverse sectional view；
Fig. 3 is the utility model site longitudinal sectional view.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete
Description.
As shown in Fig. 1 ~ 3, a kind of revealed pyramid shape light guide plate mesh point structure of the utility model is distributed in light guide plate
On 1 bottom surface, which is irregular pyramid shape slot, and four seamed edges of the pyramid shape slot are respectively the first seamed edge 2,
Second seamed edge 3, third seamed edge 4 and the 4th seamed edge 5, wherein the first seamed edge and third seamed edge be in same vertical plane, the second seamed edge
With the 4th seamed edge in same vertical plane, the length of the first seamed edge is L1, and the length of the second seamed edge is L2, the length of third seamed edge
For L3, the length of the 4th seamed edge is L4, and L1 < L3 < L2=L4, preferably, L1 length is 7um, L2 length is 14um, four
Pyramid groove deep is 6um.
The first seamed edge is 49 ° relative to the angle a of central axes in the pyramid shape slot, and the second seamed edge is relative to central axes
Angle b be 70 °, third seamed edge relative to central axes angle c be 67 °.
The lattice point structure of the utility model is applied on light guide plate, and principle is to be incident upon third into the light in light guide plate
Astigmatism is carried out when big inclined-plane where seamed edge, light is scattered out, and the small inclined-plane where the first seamed edge is to the light of injection
Auxiliary scattering is carried out, so that light scatters out, promotes scattering efficiency, and then improve brightness value, while asymmetric oblique
Face structure can not increase dot size, it is ensured that have sufficient amount of site on light guide plate.
The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used
Can teaching based on the utility model and announcement and make various replacements and modification without departing substantially from the spirit of the present invention, therefore, this
Utility model protection range should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model
And modification, and covered by present patent application claim.
