Abstract
The utility model discloses a split-type liquid crystal back light source structure, comprising a diffusion plate, an optical film and liquid crystal glass, which are installed together on a structural aluminium profile; the split-type liquid crystal back light source structure is formed by two long-edge aluminium profiles and two side-edge aluminium profiles; the structural aluminium profile is provided with a diffusion plate installing groove and a liquid crystal glass installing groove; a side shock-absorbing rubber strip is cushioned between the side edge of the liquid crystal glass and the structural aluminium profile; and a bottom shock-absorbing rubber strip is cushioned between the bottom surface of the liquid crystal glass and the liquid crystal glass installing groove. In the split-type liquid crystal back light source structure, the diffusion plate and the optical film are combined together by the aluminium profile with a specific structure, then are combined with the light source part so as to form a light source body and an optical conduction part, the assembly is simple, and the safety performance is stronger; the split-type liquid crystal back light source structure can be generalized on different sizes, and independent mold opening is not needed, so that the cost can be saved; simultaneously, two types of back light sources in an LED (light-emitting diode) light guide plate mode and a CCFL (cold cathode fluorescent lamp) tube mode can be matched; and when abnormal conditions occur, only maintenance or replacement needs to be carried out at positions of abnormal points, so that the maintenance is simple.
Description
Technical field
The utility model relates to technical field of liquid crystal display equipment, is specifically related to a kind of back light source structure that is used for liquid crystal display.
Background technology
Raising along with people's living standard and scientific and technological level, liquid crystal display has obtained extensive use because of advantages such as its fine definition, portability, low energy consumption, as LCD TV, LCD, notebook computer or the like, LCD TV is liked by people especially.At present, back light source structure main part on the market all is five metals backboard, plastic cement center, five metals upper ledge composition, it is fixing with the plastic cement center diffuser plate or LGP to be added that blooming piece clamps, and the LGP of light source and light conducting or diffuser plate and light source body are assembled into an integral body.There is following shortcoming in it: the first, structure underaction, assembling more complicated, structural stability are not high enough, and intensity is relatively poor, and security performance is strong inadequately; The second, different sizes can not be general, and as need be at the mould of the product development different size of different size in plastic cement center mode, die sinking takies sizable cost; Three, product needs to keep in repair or change at the backlight overall structure when different abnormal conditions occurring, cost height, maintenance trouble.
The utility model content
The technical problems to be solved in the utility model provides the split type LCD backlight source structure that a kind of implementation structure is simple, safe and reliable, cost is lower, easy to maintenance.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of split type LCD backlight source structure, comprise diffuser plate, blooming piece, liquid-crystalline glasses, wherein diffuser plate is installed in the bottom surface, liquid-crystalline glasses in the above, blooming piece is installed between diffuser plate and the liquid-crystalline glasses, it is characterized in that: described diffuser plate, blooming piece and liquid-crystalline glasses are installed on the structure aluminium section bar together, and the structure aluminium section bar is coated on around diffuser plate, blooming piece and the liquid-crystalline glasses.
Further, described structure aluminium section bar is a split-type structural, and it is made of two long limit aluminium section bars and dual-side aluminium section bar, and long limit aluminium section bar is identical with the structure of side aluminium section bar, is connected and fixed by Corner Link between long limit aluminium section bar and the side aluminium section bar.
Further, diffuser plate mounting groove and liquid-crystalline glasses mounting groove are arranged on the described structure aluminium section bar, diffuser plate is fixed in the diffuser plate mounting groove, and blooming piece is located at above the diffuser plate and is fixed in the diffuser plate mounting groove, and liquid-crystalline glasses is fixed on the liquid-crystalline glasses mounting groove.
Further, be provided with side damping adhesive tape between the side of described liquid-crystalline glasses and the structure aluminium section bar, be lined with damping adhesive tape in the end between liquid-crystalline glasses bottom surface and the liquid-crystalline glasses mounting groove.
The utility model is by improving the plastic cement center, with the aluminium section bar of ad hoc structure diffuser plate or LGP are added that blooming piece combines, and then make up with the Lights section, form light source body and optics conducting part in two sub-sections, its structure is more flexible, assembling is simple, structural stability is high, intensity is good, and security performance is stronger; And can be general on different sizes, only need an extrusion die to get final product general all sizes, do not need to carry out separately the die sinking of different size, can save a large sum of die cost; Simultaneously can mate LED LGP mode and two kinds of diverse type of backlight of CCFL fluorescent tube mode.Assembling process is simple, rapidly and efficiently and stability and safety.Easy to maintenance, owing to be the branch body structure, product only needs to be positioned the position at different abnormity point and keeps in repair or change when abnormal conditions occurring, faster easy.
