Abstract
The utility model discloses a direct type LED liquid crystal module which comprises a plurality of LED light bars, wherein pinboards are arranged between every two adjacent LED light bars, the pinboards are printed boards and are electrically connected with an external power supply, and the LED light bars are electrically connected with the external power supply through the pinboards. Compared with an existing liquid crystal module, the direct type LED liquid crystal module has the advantages that electric connection between the LED light bars is achieved through wiring on the pinboards, the LED light bars are finally connected with the external power supply through output ports in the pinboards to enable a whole backlight system to be driven, the design is simple, technological operability is good, wiring and wire imposing are easy to achieve, wrong connection between wire rods can not occur easily, material cost is low and manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of liquid crystal module, relates in particular to a kind of straight-down negative LED liquid crystal module.
Background technology
Along with the development of television industries, LED LCD TV is flourish at present.The designs of many lamp bars of the many employings of the back light system of straight-down negative LED LCD TV at present, realize many electrical connections between lamp bar, generally adopt at present wire rod connected mode, especially when the back light system exploitation of shutter 3D TV, because carrying out polycomponent district to LED lamp bar, needs independently control to realize subregion, in the case, as adopt traditional wire rod connected mode, each subregion all needs independently wire rod to connect, thereby it is intricate to make in back light system wire rod connect, technological operation is poor, even may there is being difficult for cabling, line ball, the mutual problem such as wrong between wire rod, Material Cost and manufacturing cost are all higher.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide the mode at the enterprising row wiring of card extender, replace traditional wire rod connected mode, realize the straight-down negative LED liquid crystal module of the electrical connection between many lamp bars in direct type backlighting system.
The technical solution of the utility model is: a kind of straight-down negative LED liquid crystal module, comprise many group LED lamp bars, described facing mutually between group LED lamp bar is provided with card extender, and described card extender is printed board, described card extender is electrically connected to external power source, and described LED lamp bar is electrically connected to external power source by card extender;
As preferably, on described card extender, be fixedly connected with connector, described LED lamp bar is fixedly connected with or is flexibly connected with connector;
As preferably, described LED lamp bar and card extender directly weld;
As preferably, described card extender comprises rigid printed board or flexible printed board according to base material character;
As preferably, described card extender can adopt single sided board, dual platen or multilayer board according to wiring level.
The beneficial effects of the utility model are: the utility model is by the cabling on card extender, realize the electrical connection between LED lamp bar, finally by delivery outlet on card extender, be connected with external power source, realize the driving of whole back light system, simplicity design, technological operation is good, is difficult for cabling, line ball, between wire rod, phase mutual connection is difficult for makeing mistakes, Material Cost and low cost of manufacture.
