Abstract
The invention discloses a light guide plate for a lateral LED TV. The light guide plate at least has one surface of incidence, and a surface of light emergence and a surface of reflection which are adjacent to the surface of incidence. A plurality of trenches which are machined and regularly distributed are arranged on the surface of light emergence and the surface of reflection. The plurality of trenches includes a plurality of first trenches which are distributed at intervals and are parallel with the surface of incidence and a plurality of second trenches which are distributed at intervals and are perpendicular to the surface of incidence. According to the light guide plate, the trenches of the light guide plate are conveniently for processing and can be manufactured by machining alone without using any printing ink chemical products and causing any pollution and do not require special exhaust equipment; the light guide plate is low in production environment requirement, low in processing cost and is environmentally friendly, and at the same time, satisfies an optical homogenous light emergence requirement of light guide plates.
Description
Technical field
The present invention relates to a kind of side entering type LED TV light guide plate.
Background technology
Among the side entering type LED TV on the reflecting surface of light guide plate general printing or the laser dotting of adopting form several sites, but local site adjusted design is loaded down with trivial details when adopting printing net-point, the proving time is long; When adopting the laser printing site, exist laser ablation edge yellow aberration, process-cycle length, a minute area edge that the shortcomings such as striped, design software complexity are arranged.
Summary of the invention
In order to overcome defects, the invention provides a kind of side entering type LED TV light guide plate, this light guide plate is not only easy to process, and can satisfy the bright dipping of light guide plate optics homogenizing.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of side entering type LED TV light guide plate, this light guide plate 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 described exiting surface or reflecting surface, these several be that groove that rule distributes comprises several first grooves spaced apart of being parallel to described incidence surface and perpendicular to several second grooves spaced apart of described incidence surface.
As a further improvement on the present invention, described the first groove and the second groove are the cross section and are U-shaped groove.
As a further improvement on the present invention, described the first groove and the second groove are the groove that the cross section is rectangle.
As a further improvement on the present invention, described the first groove and the second groove are the V-shaped groove in cross section.
As a further improvement on the present invention, described light guide plate has an incidence surface.
As a further improvement on the present invention, the spacing of described several the first grooves is identical, and the spacing of described several the second grooves is identical, and described several first grooves are from close described incidence surface one side to becoming gradually large away from described incidence surface one side.
As a further improvement on the present invention, described several the first grooves big or small identical, described several the second grooves big or small identical, and the spacing between described several first grooves near described incidence surface one side to diminishing gradually away from described incidence surface one side.
As a further improvement on the present invention, described light guide plate has two and is oppositely arranged and parallel incidence surface.
As a further improvement on the present invention, described several the first groove sizes are identical, described several the second groove sizes are identical, and the spacing between described several first grooves diminishes to this first groove place exiting surface or reflecting surface center gradually from the incidence surface near described both sides.
As a further improvement on the present invention, spacing between described several first grooves is identical, spacing between described several second grooves is identical, and the shape of described the first groove and the second groove is respectively from becoming gradually large near the incidence surface of described both sides to exiting surface or the reflecting surface center at this first groove and the second groove place.
The invention has the beneficial effects as follows: groove processing is convenient, adopts machining to get final product, and does not have using and polluting of ink chemistry product, also without special exhaust equipment, low to the production environment requirement, processing cost is low, light guide plate optics homogenizing bright dipping requirement is satisfied in more environmental protection simultaneously.

Embodiment
By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, 2, 3, a kind of side entering type LED TV light guide plate, this light guide plate 10 has an incidence surface 1 and exiting surface 2 and the 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 described incidence surface and perpendicular to several second grooves 5 spaced apart of described incidence surface.
The cross section of above-mentioned the first groove and the second groove can be U-shaped the groove of groove, rectangular groove or V-type, be the rectangle groove among the figure.
As shown in FIG., this light guide plate has an incidence surface, and this incidence surface 1 is in the side near LED 6.
The spacing of above-mentioned several the first grooves is identical, and the spacing of above-mentioned several the second grooves is identical, and several first grooves are from close incidence surface one side to becoming gradually large away from incidence surface one side.
Above-mentioned the first groove and the second groove also can arrange like this, several the first grooves big or small identical, several the 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 light guide plate of two incidence surfaces.At this moment, the first groove and the second groove can be set like this, several the first groove sizes are identical, and several the second groove sizes are identical, and the spacing between several first grooves diminishes to this first groove place exiting surface or reflecting surface center gradually from the incidence surface near both sides; Or arrange like this: the spacing between described several first grooves is identical, spacing between described several second grooves is identical, and the shape of described the first groove and the second groove is respectively from becoming gradually large near the incidence surface of described both sides to exiting surface or the reflecting surface center at this first groove and the second groove place.
