Description

A kind of universal backlight source PCB construction

Technical field

LCM module electronic technology fields are the utility model is related to, more particularly to a kind of universal backlight source PCB construction.

Background technology

With the development that science and technology is with rapid changepl. never-ending changes and improvements, backlight industry competition is more and more fierce, in order to seize market backlight production The friendship phase of product is also shorter and shorter, and the circuit of backlight product is also diversified, example:Simultaneously, simultaneously, 4 go here and there 9 simultaneously to 3 strings 8 to 3 strings 7,4 strings 12 And 6 string 6 and etc., the main defect of prior art is：Each circuit must open a corresponding PCB to correspond to, and develop Model is more, construction cycle length, development cost increase.

Therefore, it is necessary to a kind of new PCB construction is proposed to solve problem of the prior art.

Utility model content

Main purpose of the present utility model is to propose a kind of universal backlight source PCB construction, it is intended to which realization meets different circuits Use, save exploitation model, construction cycle and the development cost of product.

To achieve the above object, the utility model proposes a kind of universal backlight source PCB construction, including substrate and be arranged on Some first pads on substrate, each first pad are all independently arranged, and each first pad is connected to a via, and The spacing of any two adjacent first pads is equal.

Preferably, in addition to connecting line, the adjacent two LED pads are connected by the connecting line.

Preferably, the another side of the substrate is provided with some the second pads being connected with outside FPC, second pad Position is corresponding with first pad, and first pad passes through the via and second pad by the connecting line Connection.

Technical solutions of the utility model are by using when designing backlight PCB circuits, each first pad corresponding to PCB Connect a via, the spacing between any two the first adjacent pads is equal, the equal row that can ensure that LED of the first pad spacing The distance between row are also equal.Each first pad is independent in circuit, when determining circuit and entering by light guide plate After light length sequences LED, circuit can simply be handled, to ensure to realize the circuit that oneself needs, so as to realize Meet the use of different circuits, save exploitation model, construction cycle and the development cost of product.

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work Under, other accompanying drawings can also be obtained according to the structure shown in these accompanying drawings.

Fig. 1 is the structural representation of the embodiment of the utility model one；

Fig. 2 is that the embodiment of the utility model one made the schematic diagram after open circuit mark；

Realization, functional characteristics and the advantage of the utility model purpose will be described further referring to the drawings in conjunction with the embodiments.

Embodiment

The utility model proposes a kind of universal backlight source PCB construction.

In the utility model embodiment, the universal backlight source PCB construction；As shown in figure 1, including substrate 10 and it is arranged on Some first pads 20 of the wherein one side of substrate 10, every one first pad 20 are all independently arranged, and every one first pad 20 is connected to One via 30, via 30 play conducting when the first pad is connected with the pad of another side on substrate 10, that is, passed through Connected through via 30；And the spacing of any two the first adjacent pad 20 is equal.Therefore circuit of the present utility model has one Set pattern rule, it is possible to achieve different circuits, and traditional backlight PCB circuit does not have rule, circuit fixed single.

Technical solutions of the utility model are by using when designing backlight PCB circuits, each first pad 20 corresponding to PCB All connect a via 30, the spacing between any two the first adjacent pads 20 is equal, and the spacing of the first pad 20 is equal to be can ensure that The distance between arrangement of LED is also equal, and each first pad 20 is independent in circuit.When determine circuit and by After the entering light length of light guide plate sequences LED, circuit can simply be handled, such as, it would be desirable to the first weldering used Disk 20 is got up by connection, to ensure to realize the circuit that oneself needs, so as to realize the use for meeting different circuits, is saved Exploitation model, construction cycle and the development cost of product.

Preferably, in addition to connecting line 40, adjacent two LED pads are connected by connecting line 40.When the line for setting needs Lu Hou, it is possible to breaking processing is done to connecting line 40 by laser equipment, to realize desired circuit.

Preferably, it is preferable that the another side of substrate 10 is provided with some the second pads being connected with outside FPC (in figure not Show), the second pad locations are corresponding with the first pad 20, and the first pad 20 passes through the pad of via 30 and second by connecting line Connection.

Before the first pad 20 of the LED in welding PCB substrate 10, first to be determined on computers by Theoretical Design Distance between lamp between lamp and lamp, found in the lamp spacing by determination in PCB substrate 10 corresponding to the first pad 20, it is theoretical away from Error is had from actual lamp spacing, but error amount does not interfere with effect before lamp, as shown in Fig. 2 pair found in PCB substrate 10 The first pad 20 is answered to need to be used as a small mark, two effects of this mark, first pair of circuit is simply processed, with true The circuit for realizing that oneself is desired is protected, second will not malfunction in order to operator when pasting lamp.

Simultaneously because some the first pads 20 and arbitrary neighborhood two first for being connected to via 30 are provided with PCB substrate 10 The spacing of pad 20 is equal, and therefore, FPC is passing through corresponding via with can be connected with any second pad by connecting line 30, the first pad 20 and the second pad connect corresponding to., can be with so the PCB PIN modes that go out are different from traditional circuit Adjusted by different product diverse location, realize variation；And the pad in traditional circuit is special with going out PIN modes.

Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every Under inventive concept of the present utility model, the equivalent structure transformation made using the utility model specification and accompanying drawing content, or Directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
