Description
Technical field
The utility model relates to the liquid crystal module field, especially relates to a kind of liquid crystal module that is used for the metal front frame of liquid crystal module and has this metal front frame.
Background technology
Along with popularizing of LCD TV comprehensively, the demand of liquid crystal module increases swift and violent.See also Fig. 3, liquid crystal module is mainly assembled by metal front frame 61, Open-cell 62 and module backlight 63 three parts.Wherein Open-cell (having finished the panel after reality is adorned processing procedure) 62 is made of glasses for LCD assembly 621, X-Board (glasses for LCD assembly drive circuit board) 622 and the COF that is connected X-Board and glasses for LCD assembly (Chip On Film covers brilliant film) 623.Because the circuit board 622 width dimensions broads of Open-cell 61, when circuit board 622 vertically is fixed on the side of module 63 backlight, it will certainly exceed module 63 1 segment distances backlight, thereby make source end 64 (the source end of liquid crystal module, liquid crystal module is connected with the circuit board end at Open-cell) thickening, be unfavorable for the slimming of liquid crystal module.Therefore, usually all circuit board 622 is taked now to be folded on the metal backing of module 63 backlight and fixed, as shown in Figure 4.
See also Fig. 4.Though circuit board 622 is folded to the metal backing of module 63 backlight and fixes, the source of liquid crystal module end 64 is obvious attenuate on thickness.But owing to must keep the overall dimensions of module constant, the metal front frame 61 of source end contracts in can not be corresponding, and contracts in the part of module backlight 63, thereby the metal front frame of source end 64 and the gap d between the module backlight 63 are obviously increased.Following problem appears in this liquid crystal module easily:
1, because metal front frame 61 generally is to adopt SECC (the inferior plumbous galvanized steel of electrolysis), SGCC (electro-galvanized steel) between the 0.4mm--0.6mm or the steel plate of SGLC (hot-dip aluminizing zinc steel) material to make, so thinner thickness, intensity relatively a little less than.When mechanical test such as vibrating, fall, the metal front frame of module source end is prone to abnormal occurrencies such as distortion, distortion, has a strong impact on the overall quality of module.
2, owing to have certain clearance d between metal front frame and module backlight, extraneous foreign matter, dirty COF 623 places that enter into module source end easily.The foreign matter of metal fragment class punctures COF easily or causes short circuit, causes liquid crystal module picture abnormal occurrencies such as vertical line to occur, causes scrapping of Open-cell.
As seen, this class since the metal front frame of source end and module backlight 63 between the product quality problem that caused of excessive gap, even can do over again maintenance, also need to spend a large amount of man-hours and human and material resources, increased the cost of product greatly.
The utility model content
The utility model in order to solve the available liquid crystal module since the metal front frame of source end and module backlight between the product quality problem that causes of excessive gap, a kind of liquid crystal module that is used for the metal front frame of liquid crystal module and has this metal front frame is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of metal front frame that is used for liquid crystal module of design, comprise at least two limits, each bar limit includes a vertical plane and the surface level that is connected with described vertical plane, and the vertical plane on a limit of described metal front frame is provided with one earlier inwardly again towards the kink of the normal direction bending of surface level.
Described metal front frame is surrounded by four edges and forms.
Described kink is arranged on the middle part of described vertical plane.
The utility model also provides a kind of liquid crystal module with metal front frame, comprise metal front frame, Open-cell and module backlight, wherein, described metal front frame comprises at least two limits, each bar limit includes a vertical plane and the surface level that is connected with described vertical plane, and described Open-cell and module backlight are held between the vertical plane of metal front frame; Described Open-cell comprises a glasses for LCD assembly and the circuit board that is connected with the glasses for LCD assembly, and the vertical plane on the limit that described metal front frame is adjacent with described circuit board is provided with one earlier inwardly again towards the kink of the normal direction bending of surface level.
