Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.
Embodiment 1
Existing in the prior art how in the case where guaranteeing that the size of FPC is unlikely to excessive to solve, reaching makes FPC
Impedance is unlikely to the problem of excessively high purpose, and the embodiment of the present application provides a kind of FPC.
The FPC includes several pins, and several pins are arranged on FPC, the FPC's provided by the embodiments of the present application
It is mainly characterized by：Be arranged in several pins, have on flexible printed board identical function and arranged adjacent pin it
Between without spacing, i.e., spacing is 0.
In the embodiment of the present application, as long as function is identical and the pin of arranged adjacent, it can be considered as and constitute a pin collection
It closes.For example, each pin of each entitled " GND " in Fig. 2 is exactly function since their function is all ground connection
Identical pin；Each pin of entitled " VDD " is also that function is identical since their function is all connection power supply
Pin；And title be respectively " D0 ", " D1 " ..., the signal pins of " Dn-1 ", " Dn ", then since CLK can be separately connected
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 several pins can be constituted
In conjunction, spacing between pin all can be 0.As shown in figure 3, the spacing between pin is 0 in each pin set
Schematic diagram.
Alternatively, in each pin set that several pins can be constituted, can also only have one in the embodiment of the present application
Without spacing between pin in the pin set of part, and the spacing between the pin in another part pin set can not be 0
(there is spacing), but as the prior art as shown in Figure 2 distance away, as shown in Figure 4.FPC in Fig. 4
On, have between the pin in the pin set of part without spacing；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 pins can
To be 0, as shown in Figure 3；Alternatively, in same pin set, without spacing between some pin, and another part pin it
Between spacing then not be 0, as shown in Figure 5.
Using FPC provided by the embodiments of the present application, due to having between the pin of identical function and arranged adjacent without spacing,
It does not interspace in advance between identical function and the pin of arranged adjacent, that is, save the pin of identical function and arranged adjacent
Between gap shared by space, therefore for FPC as shown in Figure 2, even if keeping GND pin and VDD pin
Quantity is constant, can also reduce the size of FPC and not increase impedance.As it can be seen that compared with the existing technology, the embodiment of the present application provides
Scheme can guarantee FPC size be unlikely to excessive in the case where, achieve the purpose that impedance is unlikely to excessively high.
Below in conjunction with reality, by the introduction to 2~embodiment of embodiment 4, illustrate that the embodiment of the present application provides scheme and exists
Application in the field FPC.
Embodiment 2
Embodiment 2 provides a kind of FPC that can be used for display screen bonding.As shown in fig. 6, the FPC provided for embodiment 2
Structural schematic diagram.
As shown in fig. 6, each pin that the FPC includes has respectively：GND pin, VDD pin, VCI pin, D1, D2 and D3
~Dn etc..
To keep attached drawing clarity, the pins such as D3~Dn are omitted in figure.In addition, the symbol "+" in figure, indicates contraposition note
Number (mark), the symbol "+" in other figures are also used to indicate that contraposition mark, repeat no more.
In the FPC shown in Fig. 6, between 4 GND pins of each arranged adjacent, gap, i.e. adjacent row is not present
It is apart 0 between 4 GND pins of column；Similar, between 4 VDD, gap is also not present, i.e. the 4 of arranged adjacent VDD draws
It is apart 0 between foot.And for arranged adjacent but have the pin of different function, for such as D1~Dn, then between them still
It so can be with d distance away.
The 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 the prior art
The novel FPC of the one kind improved.Comparison diagram 6 and Fig. 7, it is available to draw a conclusion：
Assuming that the transverse width of the FPC shown in fig. 6 and each pin in the FPC shown in Fig. 7 is equal and is equal to w,
Gap if it exists between pin, then the distance in gap is equal to d.So, in the FPC shown in Fig. 7, if counting the 1st GND from left to right
Pin is to the transverse width A1 between D1 pin, transverse width A1=12w+11d.And in the FPC shown in fig. 6, if statistics
The 1st GND pin is to the transverse width A2 between D2 pin, transverse width A2=12w+4d from left to right.
As it can be seen that the transverse width of A2 reduces 7d for A1；Meanwhile the resistance relative to the FPC shown in Fig. 7
For anti-, the impedance of the FPC shown in fig. 6 becomes smaller there is no the reduction with transverse width.It can be seen that using the application
The scheme that embodiment provides can reach in terms of existing technologies in the case where guaranteeing that the size of FPC is unlikely to excessive
To the purpose for making FPC impedance be unlikely to excessively high.
Embodiment 3
Generally, may require that VDD pin, the impedance of GND pin are lower in practical applications --- for example, VDD pin and
The impedance of GND pin generally requires to be no more than 2 ohm；And for some signal pins, then do not require its impedance lower ---
For example, the impedance of individual signals pin within 100 ohm, can be seen as meeting the requirements.Therefore, if according to such as Fig. 2 or
The prior art as shown in Figure 7 highly sets identical as VDD pin, longitudinal height of GND pin for the longitudinal direction of signal pins
So that the impedance of signal pins reduces, be in fact less it is necessary to.
Based on above-mentioned analysis, embodiment 3 provides a kind of FPC.As shown in figure 8, the structure of the FPC provided for embodiment 3
Schematic diagram.
As shown in figure 8, each pin that the FPC includes has respectively：GND pin, VDD pin, VCI pin, D1, D2 and D3
~Dn etc..
Compared with FPC in the prior art as shown in Figure 2, in the FPC shown in Fig. 8, the longitudinal direction of each pin is highly
L2, and longitudinal height of each pin shown in Fig. 2 is L1.Relationship between L1 and L2, specially：L2=(4/7) L1.Cause
This, for the FPC shown in Fig. 2, the longitudinal direction of the FPC shown in Fig. 8 highly shortens.Due to the area and pin of pin
Generated impedance is negatively correlated, if the impedance of pin will increase it is therefore contemplated that longitudinal height of pin shortens, therefore,
In the embodiment of the present application, in order to guarantee that the impedance of VDD pin and GND pin not will increase, or excessive, Ke Yibian not will increase
Mutually increase the transverse width of VDD pin and GND pin, so that after the longitudinal direction of VDD pin and GND pin highly becomes larger, VDD
The area of pin and GND pin will not change, or will not vary widely.
Specifically, as shown in figure 8, being become by longitudinal height of FPC by L1 on the basis of FPC that can be shown in Fig. 2
While turning to L2, " golden finger " structure joined between 4 GND pins of arranged adjacent, being equivalent to draws 4 GND
Foot in a disguised form increases until there is no gaps between 4 GND pins.In other words, if each " golden finger " structure of addition is accordingly to be regarded as
GND pin is then the equal of having 7 GND pin arranged adjacents, and gap is not present between this 7 GND pins in Fig. 8.
Similarly, it compared with FPC as shown in Figure 2, between 4 VDD pins that the FPC shown in Fig. 8 includes, is also added
" golden finger " structure, being equivalent to increases 4 VDD pins in a disguised form until there is no gaps between 4 VDD pins, i.e., continuously
Away from.In other words, each " golden finger " structure of addition is accordingly to be regarded as VDD pin, is then the equal of there are 7 VDD pins adjacent in Fig. 8
Arrangement, and gap is not present between this 7 VDD pins, i.e., without spacing.
And for arranged adjacent but have the pin of different function, it, then still can be between them for such as D1~Dn
Distance away.
It should be noted that in the embodiment of the present application, L2=(4/7) L1 is properly termed as first longitudinal direction height.The application is real
It applies in example, the value of first longitudinal direction height, is the pin (GND as shown in Figure 8 for having identical function and arranged adjacent with expectation
Pin or VDD pin) impedance that has jointly is relevant.Specifically, expectation has the pin of identical function and arranged adjacent
The impedance having jointly is that the area common with the pin for having identical function and arranged adjacent is negatively correlated --- expectation
The impedance is smaller, then the area is bigger；Conversely, then the area is smaller.Therefore, can have according to expectation identical function and
The impedance that the pin of arranged adjacent has jointly, the determining area common with the pin for having identical function and arranged adjacent
(can be described as the first area), and then according to the single pin in the area, the pin for having identical function and arranged adjacent
Transverse width (such as d) and the pin for having identical function and arranged adjacent quantity, determine the first longitudinal direction height
Degree.Wherein, if assuming between the pin for having identical function and arranged adjacent described in requirement without spacing, the quantity=FPC
On it is laterally wide for the transverse width/single pin in the region of the pin for having identical function and arranged adjacent to be arranged
Degree.
Hereinafter, illustrating how to the area common according to the pin of standby identical function and arranged adjacent, and has phase
The transverse width of single pin in the pin of congenerous and arranged adjacent, determines first longitudinal direction height.
For example, the impedance that the VDD pin of 4 arranged adjacents of expectation has jointly is 2 ohm, then, if it is desired to single VDD
The corresponding area of pin is 0.08mm2Left and right, then according to the area, if VDD pin longitudinal direction height is 1mm, single VDD draws
The transverse width of foot can be 0.08mm.
Due to having different requirements for the impedance of pin in actual scene, this will lead to the area of pin in difference
There is different desired values under scene, so that the longitudinal height and transverse width of pin can answer scene and different, therefore, the application
Embodiment no longer carries out exhaustion.
The FPC shown in Fig. 8 and FPC shown in Fig. 2 are compared it is found that if 4 GND pins shown in assuming on the left of Fig. 2 are total
Be 2 ohm with the impedance generated, the transverse width of single pin is d, then, the impedance generated jointly due to GND pin with
The area of GND pin is negatively correlated, and on the left of Fig. 8 shown in the common area of GND pin be 7 × L2 × d=7 × (4/7) L1 × d
=4 × L1 × d.As it can be seen that GND pin shown on the left of the common area of 4 GND pins and Fig. 8 shown on the left of Fig. 2 is common
Area equation, therefore, the impedance that GND pin shown in the left side Fig. 8 generates jointly is also 2 ohm, does not increase impedance.
The area of the FPC shown in Fig. 8 and individual signals pin shown in Fig. 2 is compared it is found that in FPC shown in Fig. 8
The area of individual signals pin is M2=L2 × d=(4/7) L1 × d, that is to say, that the area change of individual signals pin in Fig. 8
Be the 4/7 of the area M1 of individual signals pin shown in Fig. 2, thus in Fig. 8 individual signals pin impedance, by 8 original Europe
Nurse (assumption value) changes as 8/ (4/7)=14 ohm.Due to the impedance of individual signals pin be within the scope of 100 ohm can
Receive, therefore, the structure of FPC shown in Fig. 8 still can satisfy the demand of practical application.
In the embodiment of the present application, longitudinal height of signal pins and VDD pin (or GND pin) in FPC shown in Fig. 8
It can be different.Specifically, longitudinal height of VDD pin (or GND pin) can be equal to previously described first longitudinal direction height,
And signal pins can then be equal to second longitudinal direction height.The second longitudinal direction height, for example first longitudinal direction height can be greater than, it can also
To be equal to first longitudinal direction height, or it is less than first longitudinal direction height.
Due to the impedance of signal pins, be it is negatively correlated with the area of signal pins, therefore, can be drawn according to desired signal
The impedance that foot has, determine signal pins area (can be described as second area) --- the impedance that desired signal pin has is small,
The area of signal pins is bigger；Conversely, then the area of signal pins is smaller.It in turn, can be according to the area and list determined
The transverse width (such as d) of a signal pins, determines the second longitudinal direction height.Specifically, second longitudinal direction height=individual signals
The area of pin/individual signals pin transverse width.
