Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of driver part, as shown in Figure 1, can comprise first circuit board 10, second circuit board 20 and M level coupling assembling 30.Each coupling assembling 30 can comprise the first connector 301 being arranged at first circuit board 10, the second connector 302, the connecting line 303 that are arranged at second circuit board 20.
One end of connecting line 303 is provided with N number of pin, and respectively with N number of pin one_to_one corresponding of the first connector, the other end of connecting line 303 is provided with N number of pin, respectively with N number of pin one_to_one corresponding of the second connector.Wherein, M, N >=1 is positive integer.When the installation site of above-mentioned connecting line is correct, N number of pin of connecting line one end can be connected one by one with N number of pin of the first connector 301, and N number of pin of the other end is connected one by one with N number of pin of the second connector 302.
In addition, first pin of the first connector 301 is 1. for receiving test signal T, 1. first pin of the second connector 302 be electrically connected with i-th pin (for last pin in figure) of the second connector 302, for conducting second connector 302 first pin 1. with i-th pin of the second connector 302, i >=3 are positive integer.
When 1. 1. first pin of the first connector 301 be connected with first pin of the second connector 302 by connecting line 303,1. the test signal T that 1. first pin of the first connector 301 receive can transfer to first pin of the second connector 302, is then exporting i-th pin of the second connector 302 to.Now, if i-th pin of the second connector 302 is connected by connecting line 303 with i-th pin of the first connector 301, so above-mentioned test signal T can be exported by i-th pin of the first connector 301.
In addition, second circuit board 20 is provided with the first drop-down module 201, connect a jth pin () and the earth terminal GND of the second connector 302, the signal for the jth pin by the second connector 302 is pulled down to earth terminal in Fig. 1 for second pin 2., j >=2 are positive integer.It should be noted that i and j gets different numerical value.
Wherein, above-mentioned first drop-down module 201 can comprise the 3rd resistance R3, and one end of the 3rd resistance R3 connects a jth pin of the second connector 302, and the other end is connected with earth terminal GND.The resistance of above-mentioned 3rd resistance R3 can between 0 Ω ~ 100 Ω, thus can while the signal ground of the jth pin by the second connector 302, reduce to vagabond current, make a jth pin of the second connector 302 signal can slow releasing to earth terminal GND.In addition, this first drop-down module 201 can also comprise the resistance of multiple mutual series connection, and its effect is identical with the effect of single 3rd resistance R3, and the resistance sum of multiple resistance meets 0 Ω ~ 100 Ω.
Based on this, when connecting line misplaces, when causing the first connector first pin not to be communicated with by connecting line with first pin of the second connector, the test signal that first pin of the first connector receives cannot be transferred to first pin of the second connector by connecting line, then export connecting line to by i-th pin of the second connector, i-th pin of the first connector be connected with i-th pin of the second connector by connecting line is exported without test signal.
Or when connecting line misplaces, make the pin on connecting line across two of the second connector adjacent pins, and during by above-mentioned two pin short circuits, because the deflection of connecting line is less, so all pins on this connecting line can with all pin short circuits of whole second connector, so, although the test signal that the first connector first pin receives can transfer to all pins of the second connector by connecting line, but the jth pin due to the second connector passes through the first drop-down module by above-mentioned signal ground, thus make the test signal on all pins of the second connector being in short circuit state by a jth pin ground connection of the second connector.So input to i-th pin of the second connector without test signal, then exported to i-th pin of the first connector by connecting line.
In sum, when dislocation occurs connecting line, the test signal that first pin of the first connector receives cannot export from i-th of a first connector pin.Therefore can by first pin input test signal of the first connector, then from i-th pin of the first connector detect this test signal whether export judge the first connector and the second connector whether normal by the connection status of connecting line.In addition, when connecting line generation dislocation makes connecting line by the second connector short circuit, due to the signal that first pin of the first connector receives, can by drop-down module ground, thus the first circuit board making to be provided with the first connector and the second circuit board that is provided with the second connector are in off-state, thus avoid the phenomenon that short circuit causes circuit board to damage.
In addition, when there is dislocation in connecting line 303, the pin on connecting line 303 also may be made two of the first connector 301 adjacent pin short circuits, because the deflection of connecting line 303 is less, so this connecting line 303 can and the institute's pin short circuit on whole first connector 301.Thus damage is caused to connector and circuit board.
In order to solve the problem, can be as shown in Figure 2, first circuit board 10 is provided with the second drop-down module 102, connects a jth pin and the earth terminal GND of the first connector 301, for the signal of the jth of a first connector pin is pulled down to earth terminal GND.
In the case, even if misplace when connecting line 303, make the pin on connecting line 303 by two of the first connector 301 adjacent pin short circuits, and cause all pin short circuits of this connecting line 303 and whole first connector 301.Although now the first connector 301 first test signal T that pin can receive can transfer to all pins of the first connector 301 by connecting line 303, but the jth pin due to the first connector passes through the second drop-down module 102 by above-mentioned signal ground, thus makes the test signal on all pins of the first connector 301 being in short circuit state by a jth pin ground connection of the first connector.
So, i-th pin of the second connector will be inputed to without test signal, and then export i-th pin of the first connector 301 to by connecting line 303.The first circuit board 10 being now provided with the first connector 301 and the second circuit board 20 being provided with the second connector 302 are in off-state, thus avoid the phenomenon that short circuit causes circuit board to damage.
Wherein, the second drop-down module 102 can comprise the 4th resistance R4, and one end of the 4th resistance R4 connects a jth pin of the first connector 301, and the other end is connected with earth terminal GND.And the resistance of the 4th resistance R4 can at 0 Ω ~ 100 Ω.Between, thus can, while the signal ground of the jth pin by the first connector 301, reduce vagabond current, make a jth pin of the first connector 301 signal can slow releasing to earth terminal GND.In addition, this second drop-down module 102 can also comprise the resistance of multiple mutual series connection, and its effect is identical with the effect of single 4th resistance R4, and the resistance sum of multiple resistance meets 0 Ω ~ 100 Ω.
Further, for the electronic equipment that size is less, such as undersized display device, can pass through the above-mentioned coupling assembling 30 of one-level between first circuit board 301 and second circuit board 302, just can realize the electrical connection of two circuit boards.But for larger-size display device, the size of first circuit board 301 and second circuit board 302 is also relatively large, therefore need to arrange the electrical connection that multistage coupling assembling 30 just can realize two circuit boards.Below by way of specific embodiment, the mode that first circuit board 301 and second circuit board 302 are electrically connected is described in detail by one-level coupling assembling and multistage coupling assembling.
Embodiment one

In the case, 1. first pin of the first connector 301 connect voltage source V DDIN, for the signal that receiver voltage source VDDIN provides.The signal that this voltage source V DDIN provides can directly as above-mentioned test signal T.
I-th pin of the first connector 301 connects enable signal end EN, for exporting the signal on i-th of the second connector pin to enable signal end EN.
So, if the signal that above-mentioned voltage source V DDIN provides, first pin of the second connector 302 can 1. be transferred to 1. by first pin of the first connector 301.In the case, because 1. first pin of the second connector 302 be connected with i-th pin of the second connector 302, therefore, 1. the signal that above-mentioned voltage source V DDIN provides transfers to i-th pin of the second connector 302 by first pin of the second connector 302.In addition, if i-th pin of the first connector 301 is connected with i-th pin of the second connector 302 by connecting line 303, so just can receive from i-th pin of the first connector 301 signal that above-mentioned voltage source V DDIN provides, and export this signal to enable signal end EN.So, when the signal that voltage source V DDIN provides exports eventually through enable signal end EN, can prove when connecting line 303 link position is correct.
When connecting line 303 link position is correct, between first circuit board 10 and second circuit board 20, Signal transmissions can be carried out.Such as, when above-mentioned first circuit board 10 and second circuit board 20 are for display device, above-mentioned first circuit board 10 can be arranged power integrated circuit (English: PowerIntegratedCircuit, to be called for short PowerIC).This PowerIC connects enable signal end EN, for starting under the control of enable signal end EN, and provides clock signal by connecting line 303 to second circuit board 20.And when second circuit board 20 is after receiving above-mentioned clock signal, display panel can be driven to show.
In addition, above-mentioned enable signal end EN not only can as detect connecting line 303 link position whether correct time test signal output terminal, the signal that enable signal end EN exports can also be directly inputted into the control circuit on first circuit board 10.Such as in a display device, when first circuit board 10 is for providing clock signal, above-mentioned enable signal end EN needs the enable voltage providing 3.3V to the PowerIC on first circuit board 10 usually.And for the voltage source V DDIN of display device, the voltage magnitude of input is usually 12V.
Because the voltage of voltage source V DDIN input can export enable signal end EN to by coupling assembling 30.Therefore the voltage signal in order to make enable signal end EN receive satisfies the demands.Can be as shown in Figure 3, first circuit board 10 is provided with division module 101, first pin of connection voltage source V DDIN, the first connector 301 and earth terminal GND, for under the control of earth terminal GND, the signal of voltage source V DDIN is carried out voltage division processing, and voltage division signal is exported to enable signal end EN.
So, whether the installation site that the signal of voltage source V DDIN input not only may be used for detecting connecting line is correct, can also provide voltage needed for it to enable signal end EN.
Embodiment two
M > 1 in the present embodiment, namely between first circuit board 301 and second circuit board 302 as shown in Figure 4, be provided with multistage coupling assembling 30.Wherein in Fig. 3 from top to bottom, be followed successively by first order coupling assembling 30, second level coupling assembling 30 ... and afterbody coupling assembling 30.
In the case, in first order coupling assembling 30, first pin of the first connector 301 connects voltage source V DDIN, for the signal that receiver voltage source VDDIN provides.
Except first order coupling assembling 30, in all the other coupling assemblings 30, first pin of the first connector 301 connects i-th pin of the first connector 301 in upper level coupling assembling, for realizing the cascade between adjacent coupling assembling 30.
In afterbody coupling assembling 30, i-th pin of the first connector 301 connects enable signal end EN, for exporting the signal on i-th pin of the second connector in afterbody coupling assembling 30 to enable signal end EN.
So, for first order coupling assembling 30, if the signal that above-mentioned voltage source V DDIN provides, first pin of the second connector 302 can 1. be transferred to 1. by first pin of the first connector 301.Because 1. first pin of the second connector 302 be connected with i-th pin of the second connector 302, therefore, 1. the signal that above-mentioned voltage source V DDIN provides transfers to i-th pin of the second connector 302 by first pin of the second connector 302.If i-th pin of the first connector 301 is connected with i-th pin of the second connector 302 by connecting line 303, so just can receive from i-th pin of the first connector 301 signal that above-mentioned voltage source V DDIN provides.
Next, because i-th pin of the first connector 301 in first order coupling assembling 30 is connected with first pin of the first connector 301 in next stage coupling assembling 30, therefore above-mentioned signal can be transmitted by the coupling assembling 30 of mutual cascade, and the signal finally provided by voltage source V DDIN from i-th pin of afterbody coupling assembling 30 exports enable signal end EN to.So, when the signal that voltage source V DDIN provides exports eventually through enable signal end EN, can prove when connecting line 303 link position in above-mentioned multistage coupling assembling 30 is all correct.
In addition, when first circuit board 10 and second circuit board 20 are for display device, and first circuit board 10 can be provided with PowerIC, this PowerIC connects enable signal end EN, for starting under the control of enable signal end EN, and when providing clock signal by connecting line 303 to second circuit board 20, enable signal end EN only needs the voltage of 3.3V, and the 12V voltage that voltage source V DDIN can export.So the enable signal end EN be connected with i-th pin of afterbody coupling assembling 30 satisfies the demands.Can be as shown in Figure 4, first circuit board 10 is provided with division module 101, connect first pin and the earth terminal GND of the first connector 301 in voltage source V DDIN, first order coupling assembling 30, for under the control of earth terminal GND, the signal of voltage source V DDIN is carried out voltage division processing, and first pin voltage division signal being exported to the first connector 301 in first order coupling assembling 30 1..
So, whether the installation site that the signal of voltage source V DDIN input not only may be used for detecting connecting line is correct, can also provide voltage needed for it to enable signal end EN.
Further, for embodiment one or embodiment two, above-mentioned division module 101 can comprise the first resistance R1 and the second resistance R2 of series connection mutually.
Wherein, one end of the first resistance R1 connects voltage source V DDIN, and 1. the other end connects first pin of one end of the second resistance R2 and the first connector 301.The other end of the second resistance R2 connects earth terminal GND.So, dividing potential drop can be carried out by the resistance of adjustment first resistance R1 and the second resistance R2 to voltage source V DDIN output voltage, thus the voltage that enable signal end EN is exported satisfies the demands.
