The every other embodiment being obtained under the premise of going out creative work, broadly falls into the scope of the application protection.
Below in conjunction with accompanying drawing, describe the technical scheme that each embodiment of the application provides in detail.
Embodiment 1
Present in solution prior art how in the case that the size ensureing FPC is unlikely to excessive, reach and make FPC
Impedance is unlikely to the problem of too high purpose, and the embodiment of the present application provides a kind of FPC.
This FPC includes some pins, described some pins, is arranged on FPC, this FPC's that the embodiment of the present application provides
It is mainly characterized by：Be arranged in described some pins on flexible printed board, possess identical function and arranged adjacent pin it
Between continuously away from, that is, spacing be 0.
In the embodiment of the present application, as long as function phase with and arranged adjacent pin, all can be considered as constituting a pin collection
Close.Such as, each pin of each in Fig. 2 entitled " GND ", because their function is all ground connection, is exactly therefore function
Identical pin；Each pin of entitled " VDD ", because their function is all to connect power supply, is also therefore that function phase is same
Pin；And title be respectively " D0 ", " D1 " ..., " Dn-1 ", the signal pins of " Dn ", then due to CLK can be connected respectively
Line, control signal wire or DATA line, therefore they belong to the different pin of function.
For the dimension of pin set, in the embodiment of the present application, each pin collection that described some pins can be constituted
In conjunction, the spacing between pin can be all 0.As shown in figure 3, for, in each pin set, the spacing between pin is 0
Schematic diagram.
Or, in the embodiment of the present application, it is also possible to only one in each pin set that described some pins can be constituted
Continuously away from and the spacing between the pin in another part pin set can not be 0 between pin in part pin set
(there is spacing), but distance away as prior art as shown in Figure 2, as shown in Figure 4.FPC in Fig. 4
On, have between the pin in part pin set continuously away from；And the spacing between the pin in some pin set is d1.
For the dimension of pin, in the embodiment of the present application, in same pin set, the spacing between all of pin can
To be 0, as shown in Figure 3；Or, in same pin set, between some pin continuously away from, and another part pin it
Between spacing be not then 0, as shown in Figure 5.
The FPC being provided using the embodiment of the present application, due to possess between the pin of identical function and arranged adjacent continuously away from,
It is not to interspace in advance between identical function and the pin of arranged adjacent, i.e. save the pin of identical function and arranged adjacent
Between the space shared by space, therefore for FPC as shown in Figure 2, even if keeping GND pin and VDD pin
Quantity constant it is also possible to reducing the size of FPC and not increasing impedance.It can be seen that, with respect to prior art, the embodiment of the present application provides
Scheme can ensure FPC size be unlikely to excessive in the case of, reach the purpose that impedance is unlikely to too high.
Below in conjunction with reality, by the introduction to embodiment 2～embodiment 4, illustrate that the embodiment of the present application provides scheme to exist
Application in FPC field.
Embodiment 2
Embodiment 2 provides a kind of FPC that can be used for display screen bonding.As shown in fig. 6, this FPC providing for embodiment 2
Structural representation.
As shown in fig. 6, each pin that this FPC includes has respectively：GND pin, VDD pin, VCI pin, D1, D2 and D3
～Dn etc..
For keeping accompanying drawing definition, in figure eliminates the pins such as D3～Dn.Additionally, in figure symbol "+", represent contraposition note
Number (mark), other in figures symbol "+" be also used to indicate that contraposition mark, repeat no more.
In this FPC shown in Fig. 6, between 4 GND pin of each arranged adjacent, all there is not space, i.e. adjacent row
Apart for 0 between 4 GND pin of row；Similar, between 4 VDD, there is not space, that is, the 4 of arranged adjacent VDD draws yet
Apart for 0 between pin.And for arranged adjacent but possess the pin of difference in functionality, for such as D1～Dn, then between them still
So can be with distance away d.
This FPC shown in Fig. 6, is based on a kind of FPC that can be used for display screen bonding as shown in Figure 7 in prior art
Improve a kind of new FPC obtaining.Contrast Fig. 6 and Fig. 7, can obtain to draw a conclusion：
The transverse width of each pin in this FPC shown in this FPC and Fig. 7 shown in hypothesis Fig. 6 is all equal and is equal to w,
If there is space between pin, the distance in space is equal to d.So, in this FPC shown in Fig. 7, if statistics the 1st GND from left to right
The transverse width A1 to D1 pin for the pin, this transverse width A1=12w+11d.And in this FPC shown in Fig. 6, if statistics
1st GND pin transverse width A2, this transverse width A2=12w+4d to D2 pin from left to right.
It can be seen that, for A1, the transverse width of A2 decreases 7d；Meanwhile, the resistance with respect to this FPC shown in Fig. 7
For anti-, the impedance of this FPC shown in Fig. 6 does not diminish with the minimizing of transverse width.As can be seen here, using the application
The scheme that embodiment provides, in terms of existing technologies, can reach in the case that the size ensureing FPC is unlikely to excessive
It is unlikely to too high purpose to making FPC impedance.
Embodiment 3
Usually, may require that in actual applications VDD pin, GND pin impedance relatively low such as, VDD pin and
The impedance of GND pin is general to be required to be less than 2 ohm；And for some signal pins, then do not require its impedance relatively low
Such as, the impedance of individual signals pin, within 100 ohm, can be seen as meeting requirement.Therefore, if according to such as Fig. 2 or
Prior art as shown in Figure 7, the longitudinal direction of signal pins is highly set to highly identical with the longitudinal direction of VDD pin, GND pin
So that the impedance of signal pins reduces, in fact less it is necessary.
Based on above-mentioned analysis, embodiment 3 provides a kind of FPC.As shown in figure 8, the structure of this FPC providing for embodiment 3
Schematic diagram.
As shown in figure 8, each pin that this FPC includes has respectively：GND pin, VDD pin, VCI pin, D1, D2 and D3
～Dn etc..
Compared with FPC of the prior art as shown in Figure 2, in this FPC shown in Fig. 8, the longitudinal direction of each pin is highly
L2, and the longitudinally height of each pin shown in Fig. 2 is L1.Relation between L1 and L2, specially：L2=(4/7) L1.Cause
This, for this FPC shown in respect to Fig. 2, the longitudinal direction of this FPC shown in Fig. 8 highly shortens.Area and pin due to pin
Produced impedance is negatively correlated, if it is therefore contemplated that the longitudinal direction height of pin shortens, the impedance of pin can increase, therefore,
In the embodiment of the present application, the impedance in order to ensure VDD pin and GND pin will not increase, or will not increase excessive, Ke Yibian
Mutually increase the transverse width of VDD pin and GND pin, so that after the longitudinally height change of VDD pin and GND pin is big, VDD
The area of pin and GND pin will not change, or large change will not occur.
Specifically, as shown in figure 8, can be become by L1 in the longitudinal direction height by FPC on the basis of the FPC shown in Fig. 2
While turning to L2, all add " golden finger " structure between 4 GND pin of arranged adjacent, be equivalent to and so that 4 GND is drawn
Pin is covert to be increased until there is not space between 4 GND pin.In other words, if each " golden finger " structure adding is accordingly to be regarded as
GND pin, then be the equal of to have 7 GND pin arranged adjacent in Fig. 8, and there is not space between this 7 GND pin.
Similarly, compared with FPC as shown in Figure 2, between 4 VDD pins that this FPC shown in Fig. 8 comprises, also add
" golden finger " structure, being equivalent to makes that 4 VDD pins are covert to be increased until there is not space, that is, continuously between 4 VDD pins
Away from.In other words, each " golden finger " structure adding is accordingly to be regarded as VDD pin, is then the equal of to have 7 VDD pins adjacent in Fig. 8
, and there is not space between this 7 VDD pins in arrangement, that is, continuously away from.
And for arranged adjacent but possess the pin of difference in functionality, for such as D1～Dn, then still permissible between them
Distance away.
It should be noted that in the embodiment of the present application, L2=(4/7) L1, it is properly termed as first longitudinal direction height.The application is real
Apply in example, the value of first longitudinal direction height, is the pin (GND as shown in Figure 8 possessing identical function and arranged adjacent with expectation
Pin or VDD pin) impedance that jointly possesses is related.Specifically it is desirable to possess the pin of identical function and arranged adjacent
The impedance jointly possessing, the negatively correlated expectation of the area being common with the described pin possessing identical function and arranged adjacent
This impedance is less, then this area is bigger；Conversely, then this area is less.Therefore, it can according to expectation described in possess identical function and
The impedance that the pin of arranged adjacent possesses jointly, determines the area common with the described pin possessing identical function and arranged adjacent
(can be described as the first area), and then according to the single pin in this area, the described pin possessing identical function and arranged adjacent
Transverse width (such as d), and the quantity of the described pin possessing identical function and arranged adjacent, determine that this first longitudinal direction is high
Degree.Wherein, if assuming to possess between identical function and the pin of arranged adjacent continuously away from described quantity=FPC described in requirement
Upper be used for arranging described in possess identical function and arranged adjacent the transverse width/single pin in the region of pin laterally wide
Degree.
Hereinafter, illustrate how to according to the common area of the pin for identical function and arranged adjacent, and possess phase
The transverse width of the single pin in the pin of congenerous and arranged adjacent, determines first longitudinal direction height.
Such as it is desirable to the impedance that the VDD pin of 4 arranged adjacent possesses jointly is 2 ohm, then, if requiring single VDD
The corresponding area of pin is 0.08mm2Left and right, then according to this area, if VDD pin longitudinal direction height is 1mm, single VDD draws
The transverse width of pin can be 0.08mm.
Because, in actual scene, the impedance for pin has different requirements, this can lead to the area of pin in difference
There are different desired values under scene, and then make the longitudinally height of pin and transverse width can answer scene and different, therefore, the application
Embodiment no longer carries out exhaustion.
The FPC shown in this FPC and Fig. 2 shown in contrast Fig. 8 understands, if assuming shown 4 GND pin on the left of Fig. 2 altogether
Be 2 ohm with the impedance producing, the transverse width of single pin is d, then, the impedance producing because GND pin is common with
The area of GND pin is negatively correlated, and the common area of shown GND pin on the left of Fig. 8 is 7 × L2 × d=7 × (4/7) L1 × d
=4 × L1 × d.It can be seen that, on the left of the common area of shown 4 GND pin on the left of Fig. 2 and Fig. 8, shown GND pin is common
Area equation, therefore, the common impedance producing of shown GND pin on the left of Fig. 8 is also 2 ohm, does not increase impedance.
The area of the individual signals pin shown in this FPC and Fig. 2 shown in contrast Fig. 8 understands, in the FPC shown in Fig. 8
The area of individual signals pin be M2=L2 × d=(4/7) L1 × d that is to say, that in Fig. 8 individual signals pin area change
The 4/7 of the area M1 of the individual signals pin shown in Fig. 2, thus in Fig. 8 individual signals pin impedance, by 8 original Europe
Nurse (assumption value), becomes and turns to 8/ (4/7)=14 ohm.Impedance due to individual signals pin is all can in the range of 100 ohm
Accept, therefore, the structure of the FPC shown in Fig. 8 still can meet the demand of practical application.
In the embodiment of the present application, the longitudinally height of signal pins in the FPC shown in Fig. 8 and VDD pin (or GND pin)
Can be different.Specifically, the longitudinal direction of VDD pin (or GND pin) highly can be equal to previously described first longitudinal direction height,
And signal pins then can be equal to second longitudinal direction height.This second longitudinal direction height, such as can also may be used more than first longitudinal direction height
With equal to first longitudinal direction height, or less than first longitudinal direction height.
Due to the impedance of signal pins, it is negatively correlated with the area of signal pins, therefore, it can be drawn according to desired signal
The impedance that pin possesses, determines that the impedance that area (can be described as second area) the desired signal pin of signal pins possesses is little,
The area of signal pins is bigger；Conversely, then the area of signal pins is less.And then, can be according to this area determined and list
The transverse width (such as d) of individual signal pins, determines this second longitudinal direction height.Specifically, second longitudinal direction height=individual signals
The transverse width of the area of pin/individual signals pin.
