Description
Technical field
The present invention relates to the back light source technique field, concretely, relate to backlight base plate location structure and have the base plate of location structure to assemble the method for backlight by this set.
Background technology
traditional backlight, its base plate is comprised of the sheet metal of bottom and the metal frame that is arranged on metal plate edge, in the assembling backlight, in order to make reflectance coating, LGP, diffusion barrier, under add lustre to plate and on add lustre to plate can neat fitting together, at first be that reflectance coating is fitted in LGP, successively at the another side applying diffusion barrier of LGP, lower bright enhancement film, upper bright enhancement film, then the glue frame is fastened with its on position, at last again with reflectance coating, LGP, diffusion barrier, under add lustre to plate and on the structure inversion that plate coordinates with the glue frame that adds lustre to come base plate is fastened on it, this assembling mode, easily enter foreign material in backlight, the while reflectance coating, LGP, diffusion barrier, under add lustre to plate and on the add lustre to location of plate also more difficult, therefore the bad product that produces is many, simultaneously, production efficiency is also comparatively low.
Summary of the invention
The object of the invention is to overcome the assemble method of the backlight of present back light source structure is difficult in assembling process that the deficiency in location provides a kind of base plate that is provided with location structure and this structure.
The present invention is achieved through the following technical solutions: a kind of base plate arranges the backlight of location structure, comprise base plate, glue frame, reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film, described glue frame is fastened on described base plate and forms shell, and described reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film be bonded to each other being arranged between base plate and glue frame successively; Its improvements are, the edge of described base plate is provided with locator protrusions.
The below is further elaborated above technical scheme:
Further, the edge on each limit of described base plate is provided with locator protrusions.
Further, described base plate is rectangle structure, and four limits of base plate are respectively arranged with two locator protrusions.
Below provide the assemble method of the LGP of said structure: a kind of base plate arranges the assemble method of the backlight of location structure, comprises the following steps: S1, base plate is positioned over workbench; S2, reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film are positioned over base plate successively, the locator protrusions at the edge of base plate positions reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film, makes reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film can not move at base plate; S3, the glue frame is fastened on base plate, makes reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film be fixed in successively between base plate and glue frame.
beneficial effect of the present invention is: one, the backlight of this structure, the edge of its base plate is provided with locator protrusions, in the assembling backlight, projection by the base plate edge is to reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film position successively with reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film fixedly fit in base plate, again the glue frame is fastened and base plate, by this, make reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film can not produce displacement at base plate, improved production efficiency, also improved simultaneously the qualification rate of backlight.Two, the assemble method of the backlight of this structure is: the first step is positioned over workbench with base plate; Second step, reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film are positioned over base plate successively, the locator protrusions at the edge of base plate positions reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film, makes reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film can not move at base plate; The 3rd the step, the glue frame is fastened on base plate, make reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film be fixed in successively between base plate and glue frame.Because when backlight is assembled, by gum, that reflectance coating, LGP, diffusion barrier, lower bright enhancement film and upper bright enhancement film is bonded to each other, under the condition of high temperature, each diaphragm is different from the shrinkage factor of gum, easily produce each diaphragm and frill, affect its optical effect, well avoided this situation with the backlight of the method assembling, improve the qualification rate of product, made product that good illumination effect be arranged.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the present invention is described further:
With reference to shown in Figure 1, the backlight of this structure, comprise base plate 1, glue frame 2, reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7, described glue frame 2 is fastened on described base plate 1 and forms shell, and described reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 be bonded to each other being arranged between base plate 1 and glue frame 2 successively.With reference to shown in Figure 2, described base plate 1 is rectangle structure, and four limits of base plate 1 are respectively arranged with two locator protrusions 101.
with reference to Figure 1 and Figure 2, the backlight of this structure, the edge of its base plate 1 is provided with locator protrusions 101, in the assembling backlight, 101 pairs of reflectance coatings 3 of locator protrusions by base plate 1 edge, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 position successively with reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 fixedly fit in base plate 1, again glue frame 2 is fastened and base plate 1, by this, make reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 can not produce displacement at base plate 1, improved production efficiency, also improved simultaneously the qualification rate of backlight.
With reference to shown in Figure 3, the assemble method of this backlight comprises the following steps: S1, base plate 1 is positioned over workbench; S2, reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 are positioned over base plate 1 successively, the locator protrusions 101 at the edge of base plate 1 positions reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7, makes reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 can not move at base plate 1; S3, glue frame 2 is fastened on base plate 1, makes reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 be fixed in successively between base plate 1 and glue frame 2.
Because when backlight is assembled, by gum, that reflectance coating 3, LGP 4, diffusion barrier 5, lower bright enhancement film 6 and upper bright enhancement film 7 is bonded to each other, under the condition of high temperature, each diaphragm is different from the shrinkage factor of gum, easily produce each diaphragm and frill, affect its optical effect, well avoided this situation with the backlight of the method assembling, improve the qualification rate of product, made product that good illumination effect be arranged.
