Description
Technical field
The utility model relates to a kind of module backlight, is specifically related to a kind of side-light type module backlight.
Background technology
Module backlight is one of key components and parts of LCD, because liquid crystal itself is not luminous, the function of module backlight provides sufficient brightness and the light source that is evenly distributed, and makes normally show image of liquid crystal panel.Module backlight is located at the back side of liquid crystal panel, and in order to provide a homodisperse light to liquid crystal panel, the feasible image that forms by the pixel electrode on the control liquid crystal panel is evenly thrown light on to be obtained to show.Wherein, module backlight can be divided into the down straight aphototropism mode set that incident light source is positioned at rear, the display floater back side according to the position of light source, and incident light source is positioned near the side-light type module backlight of side of display floater.Generally speaking, the module backlight of side-light type structure has light weight, slim, narrow frameization, characteristic of low energy consumption, is applicable on notebook computer and the liquid crystal display product below 14 cun; And the module backlight of straight-down negative structure more is applicable on the product of large scale liquid crystal demonstration because of the characteristics of its high brightness.
Existing side-light type module backlight includes a framework, a LGP, be located at the light source of LGP one side, be located at the light source outside reflector, be located at the LGP below and be fixed in the reflecting plate on the framework and be located at LGP and display floater between diffuser plate.Wherein, light source is a light source generator (LED of cathode fluorescent tube CCFL commonly used or high brightness), its light that sends goes into to inject LGP by the side of LGP usually, reflector, the light that reflecting plate is used for not being scattered imports LGP again to increase the utilization rate of light, the light scattering that LGP is used for light source is sent is to diffuser plate, diffuser plate makes light form diffusion and evenly diffusion, eliminate the clear zone that micro-structural forms on the LGP, realize evenly illumination, framework then is to be used for fixing LGP, light source generator, reflector, reflecting plate and diffuser plate.In the certain structures, also be provided with at least one prismatic lens in addition above diffuser plate, with the difference of further correction intensity of illumination, the light that liquid crystal panel is received can have a higher briliancy.
Above-mentioned LGP is embedded in the framework, for avoiding framework fluorescent tube first broken by the bump of LGP, thereby on LGP one periphery, a lug being set at least, the place corresponding to the lug place on the framework is provided with a location groove, for setting with fixing of LGP.Because module backlight can generate heat in use, parts such as LGP can expand with heat and contract with cold, and for avoiding use middle frame groove generation spalling phenomenon, in existing structure, between detent and lug certain clearance are arranged; Yet, the problem of Cai Yonging is thus, in the finished product handling process, or in the moving process of laptop computer displays, with the collision phenomenon back and forth that occurs between LGP and framework, send different sound, more so the bad phenomenon that lug is deviate from groove will appear in the person, directly have influence on the quality and normal use of finished product.
Summary of the invention
The utility model purpose provides a kind of back light module unit structure, the fixing LGP that it can be firm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of side-light type back light module unit structure, comprise a framework, a LGP and the light source of being located at LGP one side, at least one lateral edges of described LGP is provided with at least one ledge arrangement, be provided with detent corresponding to described ledge arrangement place on the framework, the inwall of each detent is connected with an elastic construction, elastic construction extends in detent, each ledge arrangement is contained in the detent of a correspondence, and elastic construction is butted on ledge arrangement.
Above, described framework is used for fixing light source, LGP and other blooming piece (comprising diffuser plate, reflecting plate, prism etc.), and wherein light source can be cathode fluorescent tube (CCFL) or LED lamp etc., and fluorescent tube is positioned at a side of framework.For making the position between LGP and framework keep relative fixed, at least be provided with a ledge arrangement (on edge, the left and right sides, respectively being provided with a ledge arrangement usually) on the outer peripheral edges of LGP, ledge arrangement can be rectangle lug or arc lug, with the corresponding framework of lug position on be provided with detent, described elastic construction can be that metal clips or other have certain flexible object, elastic construction is arranged in the detent, between frame side wall and LGP lug sidewall, in the time of in LGP embeds framework, constitute the elasticity engagement connection between LGP and frame side wall, making LGP be difficult for producing rocks, thereby can avoid the escape of LGP and the different sound that produces with the framework collision, improve end product quality.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model has been set up elastic construction between LGP positioning tab structure and framework, make between LGP and the framework and keep gripping orientation, prevent LGP rocking in framework, overcome the defective of the easy escape of LGP, avoid the different sound of LGP and framework collision generation simultaneously, improved the end product quality of module backlight;
2, by the setting of elastic component, it is bad to overcome the mechanism that the thermal expansion because of LGP produces;
3, adopt sheet metal can derive the high-pressure electrostatic that framework (being generally the glue frame) is produced owing to long-time energising as elastic component;
4, the integrated elastic piece structure of employing and framework is elastic component, and is simple in structure, easy to assembly.
