Abstract
The utility model provides a pair of light conducting plate, set up into the plain noodles to the side of the body, can be with the incident light scattering to the site through going into the plain noodles, the site bottom can be with being bare even reflection to going out the plain noodles, because it is big that the site cross section is the top, the bottom is little trapezoidal, the site lateral wall also can carry out the corresponding refraction and the refraction of turning over, thereby the incident light that makes the plain noodles scattering to go out arrives a plain noodles through the site scattering, reach the mesh that produces the uniform source of light, be equipped with reflection of light piece respectively on non - income plain noodles, reflection of light piece can go back the light reflex or the refraction of penetrating on the reflection of light piece, play the effect of leaded light, the luminance of light -emitting has improved, be equipped with positioning groove at the body along its length direction both sides, through positioning groove can be fixed with the body, has solved and has pasted and arouse that light conducting plate takes place the displacement and then causes the inhomogeneous problem of light -emitting through the adhesive.
Description
Technical field
The utility model relates to a kind of light guide plate.
Background technology
At present, light guide plate is all generally the backlight module for display, when light guide plate being installed on backlight module, all adopt bonding agent to be fixed on backlight module by light guide plate, because bonding agent bonding is insecure, light guide plate may be subjected to displacement, and causes bright dipping uneven.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides the light guide plate of a kind of firm position and uniform in light emission.
The utility model realizes like this, a kind of light guide plate, comprise a square body, described body comprises relatively and the light guiding surface be arranged in parallel and exiting surface, described light guiding surface is positioned at the upper surface of described body, described exiting surface is positioned at the lower surface of described body, described light guiding surface is provided with some equally distributed sites, the xsect of described site is that top is large, the inverted trapezoidal that bottom is little, one side of described body is incidence surface, other three sides of described body are non-incidence surface, described non-incidence surface is respectively equipped with a reflecting piece, described body along its length symmetria bilateralis is provided with at least one detent.
Further, the side that described body is positioned at described incidence surface offers multiple spaced arc groove successively, forms a protuberance between two adjacent described grooves.
Preferably, the material of described site is reflective ink.
Further, described detent bottom angled is arranged.
Further, bottom described detent and two side is equipped with an ink layer.
The light guide plate that the utility model provides, light face is set in body side, can incident light be scattered on site by incidence surface, light can be reflexed to exiting surface uniformly bottom site, because site xsect is that top is large, the inverted trapezoidal that bottom is little, site sidewall also can reflect and catadioptric accordingly, thus the incident light making incidence surface scatter scatters to exiting surface through site, reach the object producing uniform source of light, non-incidence surface is respectively equipped with reflecting piece, the light be mapped in reflecting piece reflection or refraction can be gone back by reflecting piece, play guide-lighting effect, improve the brightness of bright dipping, be provided with detent in both sides along its length at body, body can be fixed by detent, solve and pasted by bonding agent and the problem causing light guide plate to be subjected to displacement and then cause bright dipping uneven.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the light guide plate that the utility model provides.
Fig. 2 is the schematic diagram of site in the light guide plate that provides of the utility model.
Fig. 3 is the schematic diagram of the light guide plate further groove that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Fig. 1 ~ 3, a kind of light guide plate that the utility model embodiment provides, comprise a square body 1, body 1 comprises relatively and the light guiding surface 11 be arranged in parallel and exiting surface (not shown), light guiding surface 11 is positioned at the upper surface of body 1, exiting surface is positioned at the lower surface of body 1, light guiding surface 11 is provided with some equally distributed sites 12, the xsect of site 12 is that top is large, the inverted trapezoidal that bottom is little, one side of body 1 is incidence surface 13, other three sides of body 1 are non-incidence surface 14, non-incidence surface 14 is respectively equipped with a reflecting piece (not shown), body 1 along its length symmetria bilateralis is provided with at least one detent 15.
Further, the side that described body 1 is positioned at incidence surface 13 offers multiple spaced arc groove 16 successively, a protuberance 17 is formed between two adjacent arcing groove 16, be refracted after the light of luminophor (not shown) enters arc groove 14, make to enter the uniform light in body 1, add the brightness of the penumbra area of light guide plate.
Preferably, the material of described site 12 is reflective ink, and reflective ink can produce the gloss as minute surface, and reflecting effect is good.
Particularly, described detent 15 bottom angled is arranged, and avoids on body 1, offer detent 15 and causes body 1 edge to collapse the problem on limit, improve the yield of product.
Further, bottom described detent 15 and two side is equipped with an ink layer (not shown), and the light be mapped on ink layer reflection or refraction can be gone back by ink layer, improve the brightness of bright dipping.
The light guide plate that the utility model provides, in body 1 side, incidence surface 13 is set, incident light can be scattered on site 12 by incidence surface 13, light can be reflexed to exiting surface uniformly bottom site 12, because site 12 xsect is that top is large, the inverted trapezoidal that bottom is little, site 12 sidewall also can reflect and catadioptric accordingly, thus the incident light making incidence surface 13 scatter scatters to exiting surface through site 12, reach the object producing uniform source of light, non-incidence surface 14 is respectively equipped with reflecting piece, the light be mapped in reflecting piece reflection or refraction can be gone back by reflecting piece, play guide-lighting effect, improve the brightness of bright dipping, be provided with detent 15 in both sides along its length at body 1, body 1 can be fixed by detent 15, solve and pasted by bonding agent and the problem causing light guide plate to be subjected to displacement and then cause bright dipping uneven.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
