Abstract
The utility model discloses a light guide plate applied to a side entering type LED TV. The light guide plate at least comprises a light incoming surface, a light emitting surface and a reflecting surface, wherein the light emitting surface and the reflecting surface are adjacent to the light incoming surface. A number of grooves which are regularly distributed are mechanically processed on the light emitting surface or the reflecting surface. A number of grooves which are regularly distributed comprise a number of first grooves which are distributed at intervals and are parallel to the light incoming surface and a number of second grooves which are distributed at intervals and are perpendicular to the light incoming surface. The grooves of the light guide plate are conveniently processed and mechanically processed without the use and the pollution of ink chemicals and without special air exhausting equipment. The requirement for the production environment is low, and the processing cost is low. The environment is protected, and at the same time the requirement of optical equalized light emitting of the light guide plate is satisfied.
Description
Technical field
The utility model relates to a kind of side entering type LED TV and uses LGP.
Background technology
Among the side entering type LED TV on the reflecting surface of LGP general printing or the laser dotting of adopting form several sites, but the adjustment design of local site is loaded down with trivial details when adopting printing net-point, the proving time is long; When adopting the laser printing site, there are laser ablation edge yellow aberration, process-cycle length, divide area edge that shortcomings such as striped, design software complicacy are arranged.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of side entering type LED TV to use LGP, and this LGP is not only easy to process, and can satisfy the bright dipping of LGP optics homogenizing.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of side entering type LED TV uses LGP; This LGP has an incidence surface and exiting surface and the reflecting surface adjacent with this incidence surface at least; Machining has several to be the groove that rule distributes on said exiting surface or reflecting surface, these several be that groove that rule distributes comprises several first grooves spaced apart of being parallel to said incidence surface and perpendicular to several second grooves spaced apart of said incidence surface.
As the further improvement of the utility model, said first groove and second groove are the groove that the cross section is the U type.
As the further improvement of the utility model, said first groove and second groove are the groove that the cross section is rectangle.
As the further improvement of the utility model, said first groove and second groove are the V-shaped groove in cross section.
As the further improvement of the utility model, said LGP has an incidence surface.
As the further improvement of the utility model, the spacing of said several first grooves is identical, and the spacing of said several second grooves is identical, and said several first grooves near said incidence surface one side to becoming big gradually away from said incidence surface one side.
Further improvement as the utility model; Said several first grooves big or small identical; Said several second grooves big or small identical, and the spacing between said several first grooves near said incidence surface one side to diminishing gradually away from said incidence surface one side.
As the further improvement of the utility model, said LGP has two and is oppositely arranged and parallel incidence surface.
Further improvement as the utility model; Said several first groove sizes are identical; Said several second groove sizes are identical, and the spacing between said several first grooves diminishes to this first groove place exiting surface or reflecting surface center from the incidence surface near said both sides gradually.
Further improvement as the utility model; Spacing between said several first grooves is identical; Spacing between said several second grooves is identical, and the shape of said first groove and second groove is respectively from becoming big near the incidence surface of said both sides to the exiting surface or the reflecting surface center at this first groove and second groove place gradually.
The beneficial effect of the utility model is: groove processing is convenient, adopts machining to get final product, and does not have using and polluting of ink chemistry article; Also do not have special exhaust equipment, low to the production environment requirement, processing cost is low; LGP optics homogenizing bright dipping requirement is satisfied in more environmental protection simultaneously.

Embodiment
In conjunction with accompanying drawing, the utility model is elaborated, but the protection domain of the utility model is not limited to following embodiment.
Like Fig. 1,2, shown in 3; A kind of side entering type LED TV uses LGP; This LGP 10 has an incidence surface 1 and the exiting surface 2 and reflecting surface 3 adjacent with this incidence surface at least; Machining has several to be the groove that rule distributes on exiting surface 2, these several be that groove that rule distributes comprises several first grooves 4 spaced apart of being parallel to said incidence surface and perpendicular to several second grooves 5 spaced apart of said incidence surface.
But the groove of groove, rectangular groove or the V-type of the cross section U type of above-mentioned first groove and second groove is the rectangle groove among the figure.
Shown in figure, this LGP has an incidence surface, and this incidence surface 1 is in the side near LED 6.
The spacing of above-mentioned several first grooves is identical, and the spacing of above-mentioned several second grooves is identical, and several first grooves near incidence surface one side to becoming big gradually away from incidence surface one side.
Above-mentioned first groove and second groove also can be provided with like this, several first grooves big or small identical, several second grooves big or small identical, and the spacing between several first grooves near incidence surface one side to diminishing gradually away from incidence surface one side.
This structure also can be used for having on the LGP of two incidence surfaces.At this moment; First groove and second groove can be set like this; Several first groove sizes are identical, and several second groove sizes are identical, and the spacing between several first grooves diminishes to this first groove place exiting surface or reflecting surface center from the incidence surface near both sides gradually; Or be provided with like this: the spacing between said several first grooves is identical; Spacing between said several second grooves is identical, and the shape of said first groove and second groove is respectively from becoming big near the incidence surface of said both sides to the exiting surface or the reflecting surface center at this first groove and second groove place gradually.
