Abstract
The utility model relates to a liquid-crystal display module comprising an iron frame (2), a rubber frame (1) and a light guide plate (3). The liquid-crystal display module is characterized in that the rubber frame (1) is of a hollow frame structure and comprises a rubber frame inner side (12), the iron frame (2) comprises an iron frame inner side (22) and an iron frame outer side (21), the light guide plate (3) is arranged below the iron frame (2), the iron frame outer side (21) is embedded into the rubber frame inner side (12), the light guide plate (3) and the rubber frame inner side (12) are integrally adhered, and the iron frame inner side (22) is uniformly coated by silver. The iron frame, the rubber frame and the light guide plate are integrally molded in an injection manner, the periphery of the iron frame inner side is coated by silver, so that the iron frame inner side has a reflecting function so as to substitute for a reflecting sheet in an existing liquid-crystal display module, and accordingly, assembly number and assembly procedures of the liquid-crystal display module can be reduced, and the integral structural strength of the liquid-crystal display module is greatly improved.
Description
Technical field
The utility model relates to field of liquid crystal display, relates in particular to a kind of liquid crystal display module.
Background technology
The characteristics such as liquid crystal indicator has that quality is light, thin thickness, low-power consumption and radiation are little have been widely used in the fields such as infotech, multimedia technology, have become the main flow of various display device.Because liquid crystal itself is not luminous, needs backlight source module to provide light source for it.With reference to Fig. 1, Fig. 1 is the structural representation that available liquid crystal shows module, backlight module mainly is to be assembled by more than ten kind of assemblies such as glue frame 1, chase 2, light guide plate 3, reflector plate 4, lower diffusion sheet, lower bright enhancement film, upper bright enhancement film, black and white double faced adhesive tape, LED, flexible PCBs, assembling procedure is more, the assembling part Geological Problems appears easily, and glue frame 1, light guide plate 3,2 three important structural members of chase are to connect or the use adhered by double sided plaster by buckle, so that the connection between the three is very unstable, cause easily product in the later stage use, quality problems to occur.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure and high liquid crystal display module of intensity.
In order to solve the present technique problem, the utility model provides a kind of liquid crystal display module, comprise chase, glue frame and light guide plate, it is characterized in that described glue frame is the framed structure of hollow, described glue frame comprises that the glue frame is inboard, described chase comprises the inboard and chase outside of chase, and described light guide plate is positioned under the described chase, and it is inboard that the described chase outside embeds the glue frame, the inboard gummed of described light guide plate and described glue frame is integrated, and described chase inboard evenly is coated with silver.
In above-mentioned liquid crystal display module, it is characterized in that the chase arranged outside has lug boss.
In above-mentioned liquid crystal display module, it is characterized in that described glue frame and light guide plate junction are concaveconvex structure.
In above-mentioned liquid crystal display module, it is characterized in that described lug boss is point-like.
The utility model liquid crystal display module is injection molded into one with chase, glue frame and light guide plate, does silver-plated processing in the chase inboard all around simultaneously, makes the chase inboard have reflective effect, thereby replaces available liquid crystal to show reflector plate in the module.Can reduce component count and the assembly process of liquid crystal display module by above measure, thereby can reduce the quality problems in the production run, thereby raising yield rate, simultaneously owing to glue frame, light guide plate, three important structural members of chase are injection moulding all-in-one-pieces, so the overall construction intensity of liquid crystal display module and reliability all improve greatly.In the chase arranged outside bulge-structure is arranged in addition
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation that available liquid crystal shows module;
Fig. 2 is the structural representation of the utility model liquid crystal display module;
Fig. 3 is the structural representation of the utility model liquid crystal display module chase;
Embodiment
The utility model liquid crystal display module comprises glue frame 1, chase 2 and light guide plate 3, glue frame 1 is the framed structure of a hollow, glue frame 1 is generally square structure, also can be according to the concrete structure of liquid crystal module and different, rounded or polygon for example, glue frame 1 comprises hollow region 11 and glue frame inboard 12, chase 2 also is the framed structure of a hollow, chase 2 comprises the chase outside 21 and chase inboard 22, the chase outside 21 is slightly larger than glue frame inboard 12, and chase 2 embeds the glue frame 1 from glue frame inboard 12, and chase inboard 22 evenly is coated with one deck silver, light guide plate 3 is positioned on the chase 2, and light guide plate 3 is connected with glue frame inboard 12.
In order to strengthen the strength of joint of chase 2 and glue frame 1, can be at chase arranged outside lug boss 23, during mould-injection frame 1, lug boss 23 embeds in the glue frame 1 fully on chase 2 bases, and lug boss 23 can be any shape, is preferably in the present embodiment the point-like projection.In order to strengthen the strength of joint of glue frame 1 and light guide plate 3, can adopt rough structure in glue frame 1 and the junction of light guide plate 3 simultaneously.
Chase 2 can adopt stainless steel to be stamped to form, and glue frame 1 can adopt the mixed material of polycarbonate and glass fibre, and light guide plate 3 adopts has high reflectivity and the not new material of extinction, for example polymethyl methacrylate base photodiffusion material.
With glue frame 1, chase 2 and light guide plate 3 are injection molded into integrative-structure needs two cover master mold and male models, first set master mold and male model are respectively the first master mold and the first male model, the second cover master mold and male model are respectively the second master mold and the second male model, at first chase 2 is put into the first master mold, the first male model and the first master mold are closed, mould-injection frame 1 around chase 2, remove the first male model, after 1 cooling of glue frame, take out chase 2, glue frame 1 and chase 2 are put into the second master mold together, the second male model and the second master mold are closed, and injection molding light guide plate 3 on glue frame 1 and chase 2 bases is so that light guide plate 3 links into an integrated entity with glue frame 1.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
