Abstract
The utility model discloses a crease-resistant backlight source module. The crease-resistant backlight source module comprises a base, a surface frame, a light source, an FPC (Flexible Printed Circuit), a reflective film, a light guide plate, diffusion films and bright enhancement films, wherein the light source, the FPC, the reflective film, the light guide plate, the diffusion film and the bright enhancement film are contained in a space formed by the base and the surface frame. The crease-resistant backlight source module disclosed by the utility model has the advantages that one side of the reflective piece close to the light source is set into a plurality of sections of cutting and penetrating structures or a whole section of cutting and penetrating structure, so that the light source end can be disconnected from a visual area part, and the reflective film (piece) of the visual area part can not be influenced by reflective creases at the light source, so that the problem of non-uniform brightness and darkness can not be caused. In addition, in order to better realize the effect of the utility model, the structure design with two layers of light enhancement films and two layers of diffusion films is adopted, so that the light effect of the light emitting surface is more uniform.
Description
Technical field
The utility model belongs to backlight source module field, especially relates to a kind of backlight source module with good anti-wrinkle effect.
Background technology
Liquid crystal display is more and more applied to social every field, and because liquid crystal panel itself can be not luminous, therefore side light-entering type light source module is commonly used to as its backlight, to illuminate liquid crystal panel.The light source of present liquid crystal display is substantially all light emitting diode (light-emitting diode, LED), because LED has the advantages such as low power consumption, environmental protection, long service life; But the heat that LED produces after long-time running often can cause the problem of some reliabilitys.Existing backlight source module is in the time of the thermal shock reliability test of high temperature (general 65-85 ℃) and low temperature (general 30-40 ℃), the reflectance coating (sheet) of source ends is easily launched wrinkle, thereby the phenomenon that light and shade is inhomogeneous appears in the source ends that causes luminous zone, affect the performance of backlight source module.
Utility model content
The purpose of this utility model is to provide a kind of backlight source module with good anti-wrinkle effect, solves the defect that prior art exists.
For realizing above-mentioned wood, the technical solution adopted in the utility model is:
A kind of anti-wrinkle backlight source module, comprise: glue shell iron-clad integrated pedestal, chase, be placed in LED light source, FPC wiring board, reflectance coating, LGP, diffusion barrier, the bright enhancement film in the space of base and chase composition, FPC wiring board is fixed by sticking double faced adhesive tape, and described reflectance coating is provided with to cut near light source one side wears structure.
Further: described cutting wear structure be multistage cut wear or one section cut and wear.
Further: the space of described base and face frame composition is also equipped with photomask, the tight overlaying frame of described photomask.
Further: described diffusion barrier comprises diffusion barrier and lower diffusion barrier, and described bright enhancement film is two-layer, and two-layer bright enhancement film is laid between lower diffusion barrier and upper diffusion barrier.
Described diffusion barrier can be only one deck, and described bright enhancement film is two-layer, and two-layer bright enhancement film is all laid on diffusion barrier.
Further: described base is glue shell iron-clad integrated pedestal.
Further: described light source is emitting led light source.
Further: described face frame is chase.
The utility model is cut and is worn structure by reflector plate is arranged to multistage or one whole section near light source one side, thereby can make source ends and vision area part disconnect in incision, the reflectance coating (sheet) of vision area part can not be subject to the impact of light source place reflection wrinkle, thereby can not produce the inhomogeneous problem of light and shade.In addition, in order better to realize effect of the present utility model, the utility model adopts the structural design of two-layer bright enhancement film and two-layer diffusion barrier, makes the light effects of light-emitting area more even.
Accompanying drawing explanation
Fig. 1 is the backlight source module structural representation that multistage is cut the wrinkle effect of wearing structure;
Fig. 2 is one section of backlight source module structural representation of cutting the wrinkle effect of wearing structure;
Fig. 3 is another example structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Backlight source module as shown in Figure 1, comprises glue shell iron-clad integrated pedestal 1, and chase 2 is placed in LED light source 5, FPC wiring board 6, reflectance coating 3, LGP 4, diffusion barrier, bright enhancement film, the photomask 9 in the space of base and chase composition; FPC wiring board is pasted fixing by double faced adhesive tape 61, reflectance coating 3 is provided with multistage near light source one side and cuts and wear structure 31.Diffusion barrier comprises diffusion barrier 72 and lower diffusion barrier 71, and described bright enhancement film is two-layer, and two-layer bright enhancement film 81,82 is laid between lower diffusion barrier 71 and upper diffusion barrier 72; Photomask 9 is close to chase 2.The utility model is cut and is worn structure by reflector plate is arranged to multistage near light source one side, thereby can make source ends and vision area part disconnect in incision, the reflectance coating (sheet) of vision area part can not be subject to the impact of light source place reflection wrinkle, thereby can not produce the inhomogeneous problem of light and shade.In addition, in order better to realize effect of the present utility model, the utility model adopts the structural design of two-layer bright enhancement film and two-layer diffusion barrier, makes the light effects of light-emitting area more even.
The utility model can be also structure as shown in Figure 2, and the main distinction of its structure and last embodiment is: reflectance coating 3 is arranged to one whole section near light source one side and is cut and wear structure 31.Can realize equally goal of the invention of the present utility model.
Structure of the present utility model can be also that the main distinction of its structure and last embodiment is as shown in Figure 3: 71 of diffusion barriers are one deck, and bright enhancement film is still two-layer, and two-layer bright enhancement film 81,82 is all laid on diffusion barrier 71.Can realize equally goal of the invention of the present utility model.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
