Abstract
The invention discloses a light guide plate construction comprising a light guide zone, a top surface, a bottom surface, a front end surface, and a tail end surface. The top surface and the bottom surface are respectively located at two opposite side surfaces of the light guide zone; and the front end surface and the tail end surface are respectively arranged at two opposite side ends of the light guide zone. The top surface has a first top surface, a second top surface and a third top surface; and the second top surface extends and is connected between the first top surface and the third top surface in an inclined mode. Therefore, a thin light guide plate can be manufactured, thereby reducing the thickness of the light guide plate and lowering the manufacturing cost.
Description
Technical field
The present invention relates to a kind of light guide plate structure; Particularly about a kind of improved structure of the light guide plate for backlight module, to reduce the thickness of light guide plate.
Background technology
The exploitation of information electronic product in recent years and design are more stressed light, thin, short, little, and under this trend, interiors of products member relatively starts to simplify, or demand reduces thickness.For the backlight module of liquid crystal display (LCD), in the member of backlight module, account for the thickness of backlight module significant proportion as the light guide plate of light source guiding medium.In order to reduce manufacturing cost and the gross thickness of backlight module, so light guide plate certainly will be towards slimming and lightweight development.
The shape of known light guide plate can roughly be divided into plate and wedge-shaped board.Generally speaking, the thickness that plate light guide plate 1 can form from light inlet side 13 is for the even Yi Zhi of Jun ﹝ is as 1 Shi ﹞ of figure, the rectangular slab that therefore plate light guide plate is consistency of thickness.Relative, wedge type light guide plate 2 can form thicker thickness from light inlet side 13, and extends to form gradually thinner Hou Du ﹝ as 2 Shi ﹞ of figure, and its overall section is that thick, one side Bao ﹝ is the slightly wedge-shaped board of triangle Pou Mian ﹞ on one side.But, no matter there is with the structure of plate light guide plate or wedge type light guide plate the shortcoming that its section thickness is thicker, therefore it has the slimming of being unfavorable for.
In addition, the structure of known light guide plate, for example: TaiWan, China patent announcement M259924 〝 light conducting plate structure 〞 new patent, it discloses a kind of light conducting plate structure, it is mainly in a tabular light guide plate, form the optically focused totem of several protrusions or recessed surperficial polygonal body, and optically focused totem is to be arranged in light guide plate with array form, in order to increase reflection and the refraction of light, and the light source transmitting in light guide plate is directed to the surface direction that forms optically focused totem.
The structure of another known light guide plate, for example: TaiWan, China patent announcement M286932 〝 light conducting plate structure improvement 〞 new patent, it discloses a kind of light conducting plate structure improvement, and this light guide plate surface has the groove that sequentially arrangement forms, groove is V-shape, and is a plane between two groove tops.
The structure of another known light guide plate, for example: Chinese patent discloses No. 1553226 〝 backlight module and light guide plate 〞 patent of invention thereof, it discloses a kind of light guide plate, it comprises a body, wherein this light guide plate also comprises that one is arranged on the dielectric layer on this body, the refractive index of this dielectric layer is less than the refractive index of this body, and this dielectric layer also comprises an exiting surface, and this exiting surface has multiple groove structures.
The structure of another known light guide plate, for example: Chinese patent discloses No. 1609682 〝 surface illuminating device and light guide plate 〞 patent of invention thereof, and it discloses a kind of surface illuminating device and light guide plate thereof.This surface illuminating device comprises at least one pointolite and a light guide plate, this light guide plate comprises at least one light entrance face, bottom surface and with this bottom surface relative light-emitting face crossing with this light entrance face, wherein, this at least one light entrance face has multiple groovings, the width of this grooving or the degree of depth in gradient formula change, and this at least one pointolite is right against the grooving setting with breadth extreme or the degree of depth.
The structure of another known light guide plate, for example: TaiWan, China patent announcement M272111 〝 structure of light guiding of light conducting board improvement 〞 new patent, it discloses a kind of light guide plate is to have to accept the incidence surface of luminophor light source, the bottom surface connected with above-mentioned incidence surface and relative to by the exiting surface of luminophor light source output with bottom surface, and luminophor is arranged at a side of light guide plate incidence surface; Wherein: the incidence surface of this light guide plate has a plurality of multiple-angle pyramid structures, the light incidence source of luminophor, via multiple-angle pyramid structure, can increase light source diffusion, and the light source that luminophor produces is evenly shed towards light guide plate exiting surface.
The structure of another known light guide plate, for example: TaiWan, China patent discloses 〝 light guide plate 〞 new patent No. 200728861, it discloses a kind of light guide plate, it is to adopt from prism facets and outwards tiltedly establish toward bottom surface in the sidewall of light guide plate light inlet side, enter suitably to elongate light source the position that is incident upon first prism facets after light guide plate, avoid the excessively bright situation of brightness of the prism facets that approaches light inlet side to occur.
But, the known light guide plate structure of aforementioned No. M259924, No. M286932, No. 1553226 and No. 1609682 only changes the exiting surface structure of plate light guide plate, but the main-body structure of light guide plate still belongs to plate structure actually, therefore its integral thickness does not reduce.In addition, the known light guide plate structure of aforementioned No. M272111 and No. 200728861 only changes the incidence surface structure of wedge type light guide plate, but the main-body structure of light guide plate still belongs to wedge type structure actually, and its integral thickness does not reduce.Therefore, the structure of conventional light guide plate is still necessary further to improve its structure, to improve the thickness problem of conventional light guide plate.Aforementioned patent is only the reference of the technology of the present invention background and current technical development state is described, the scope that it is not intended to limiting the invention.
In view of this, the present invention provides a kind of light guide plate structure in order to meet the demand, an end face is divided into one first end face, one second end face and one the 3rd end face by it, and this second end face is connected between this first end face and the 3rd end face, to solve the thickness problem of conventional light guide plate with a gradient.
