Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Liquid crystal module of the present utility model, mainly through the integrated design by module backboard and center and lamp bar and aluminium base, is integrated together the several parts affecting border width by new structural design, thus frame before reducing front width of frame or directly cancelling.
Below in conjunction with accompanying drawing, embodiment of the present utility model is introduced.
Embodiment 1
Fig. 2 is the structural representation of the liquid crystal module with ultra-narrow frame of an embodiment of the present utility model.
As in figure 2 it is shown, modular structure of the present utility model includes front frame 1, is oppositely arranged and connects fixing liquid crystal panel 10 and backlight module, backlight module includes back frame 11 and the optical module being arranged in back frame 11. Wherein, back frame 11 can adopt the one-body molded formation of aluminium material, and this back frame 11 can include sidepiece and bottom, sidepiece and bottom and be formed with the receiving space housing optical module, being formed with the support portion supporting liquid crystal panel 10 on sidepiece, liquid crystal panel 10 is fixed in aluminum back frame by support portion. The edge of liquid crystal panel 10 can flush with the outermost face of the sidepiece of back frame 11, namely liquid crystal panel 10 outermost end and outermost end on same vertical plane, now, the top of the sidepiece of back frame 11 is a plane, overall contacts with liquid crystal panel 10. Can also the sidepiece of back frame 11 be formed step-like, liquid crystal panel 10 only with a part for sidepiece, namely stage portion contacts. In an embodiment of the present utility model, the width of the support portion supporting liquid crystal panel 10 can be preferably 2-3mm, but be not limited to that this.
In this utility model, front frame 1 can be covered on the side of liquid crystal panel 10, to be fixed in back frame 11 by liquid crystal panel 10. By existing any fixed form, front frame 1, liquid crystal panel 10 and back frame 11 can be fixed, such as front frame 1 and back frame 11 can pass through to arrange the screw of former frame 1 side and be fixed, and liquid crystal panel 10 can be bonded on the support portion of back frame 11 by double faced adhesive tape. When adopting bonding way fixative crystal panel 10, the whole part that can contact with support portion at liquid crystal panel 11 all sticks double faced adhesive tape, and what so can consolidate is fixed to liquid crystal panel 10 in back frame 11. Certainly, when being fixed by front frame 1, it is possible to do not use double faced adhesive tape to be bonded in back frame 11 by liquid crystal panel 10, and only need to by the overlapping edges of liquid crystal panel 10 on support portion, in this case, the width of support portion need to arrange wider.
Optical module includes reflector 7, light guide plate 8 and the optical film material 9 that lamination successively is arranged on the bottom of back frame 11, and being arranged on the sidepiece of aluminum back frame, and the light source 3 between sidepiece and light guide plate, it is preferable that, light source can be LED, and light source 3 can be directly welded in back frame 11. The light-emitting area of light source 3 distance from screen display area is identical with the LED light-emitting area of the existing modular structure distance from screen display area, is all distance A, so will not produce the phenomenon of LED shadow.
Reflector 7, light guide plate 8 and optical film material 9 are known existing structure, for avoiding repeating, omit at this and are discussed in detail.
In the present embodiment, owing to adopting the back frame 11 of one-body molded formation to instead of the parts such as the glue frame of existing modular structure, backboard, heat sink, aluminium base, thus eliminating the thickness of these parts, the frame making module can narrow to greatest extent, at least compared to the narrow 2mm of the border width of the module of existing design, it is preferable that the border width of the module of the present embodiment is below 6mm, and owing to back frame entirety is supported by aluminum, it is thus possible to improve radiating effect further.
Embodiment 2
Fig. 3 is the structural representation of the liquid crystal module of the Rimless of another embodiment of the present utility model. The modular structure of the present embodiment is substantially the same with the modular structure of above-described embodiment, outside except without front frame. So, owing to eliminating front frame such that it is able to reach the effect of Rimless. When Rimless, liquid crystal panel 10 is adhered directly on the support portion of back frame 11 by smearing double faced adhesive tape overleaf, is so no longer necessary to the liquid crystal display screen of front frame 1 fixative crystal panel 10, thus reaching the effect of Rimless.
In the present embodiment, extra border structure (front frame) is not used to fix the liquid crystal display screen of liquid crystal panel, liquid crystal panel connection integrated with aluminium base frame is realized by bonding mode, whole liquid crystal module does not have frame, increase the effective display area of liquid crystal module and make liquid crystal module more attractive in appearance, also oversize liquid crystal display screen is made to carry out splicing more feasible and convenient, better effects if.
Additionally, this utility model also provides for the liquid crystal indicator of a kind of liquid crystal module including above-described embodiment.
