Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
It is bright, part relevant to the utility model is illustrated only for ease of description, in attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 show a kind of structural schematic diagram of binding component of the offer of the utility model embodiment one, and the present embodiment can
The case where suitable for being bound with display panel, the binding component 10 include pad area 100, and pad area 100 includes multiple sons
Pad area, multiple sub- pad areas are arranged along first direction, and every sub- pad area includes multiple first pads 111；Bind component
10 the first pad 111 for being bound with the second pad being arranged on display panel, the second pad respectively with the first pad
It corresponds, the spacing between multiple first pads far from pad area center is greater than the more of adjacent pads district center position
Spacing between a first pad, spacing and the first pad and the second pad between multiple first pads can offset at just
Than.Wherein, the position away from 100 center A-A ' of pad area is remoter, between the first adjacent pad 111 in sub- pad area
Spacing is bigger, the first pad 111 and pad to be bound can offset range it is also bigger.
Specifically, binding component 10 can be bound with display panel by pad.Weldering is set on binding component 10
Panel 100, pad area 100 include multiple sub- pad areas, such as binding component 10 shown in FIG. 1, and pad area 100 includes first
The sub- pad area 103 of sub- pad area 101, the second sub- pad area 102, third, the 4th sub- pad area 104 and the 5th sub- pad area 105.
Optionally, binding component 10 is that segmented binds component 10, and Fig. 2 is the segmented binding portion that the utility model embodiment one provides
The structural schematic diagram of part, with reference to Fig. 2, pad area 100 includes the first sub- pad area 101, the second sub- pad area 102, third
Pad area 103, the 4th sub- pad area 104 and the 5th sub- pad area 105, and every sub- pad area is separately positioned on binding component 10
Different segmentations in, and then can be bound to avoid monoblock type 10 size of component it is too long cause to bind component 10 pass through pad and display
There is the risk of contraposition offset in panel binding, and deviate larger problem in binding 10 end positions of component.
When environment temperature is excessively high, binding component 10 can be expanded, and in general, and the expansion of binding component 10 is
Non-uniform, the swell increment for binding 10 center of component is smaller, remoter from center, and the swell increment for binding component 10 is more
Greatly.And in traditional binding component 10, the first pad 111 is uniformly distributed in the pad area 100 of binding component 10, then for each
First pad 111, under the premise of guaranteeing that binding is reliable, the offset size that each first pad 111 allows is identical.Due to tying up
The above-mentioned expansion unevenness situation for determining component 10, it is remoter from binding 10 center of component, bind the pad and display surface of component 10
Contraposition offset is bigger when plate pad is bound, then closer to the actual shifts of the first pad 111 of binding 10 end positions of component
Bigger, the easier offset ranges beyond permission are measured, contraposition when binding component 10 being caused to bind with display panel is bad to ask
Topic.
Based on the problem, binding component 10 provided by the embodiment, by it is multiple arrange along first direction in sub- pad area it is more
A first pad 111 is set as the different structure of spacing, specifically, remoter from center, adjacent first in sub- pad area
The distance between pad 111 is bigger.The first weldering with reference to Fig. 1 and Fig. 2, in the first sub- pad area 101 and the 5th sub- pad area 105
Spacing between disk 111 is maximum, and the spacing between the first pad 111 in the sub- pad area 103 of third is minimum.Bind component 10 with
When display panel is bound, the distance between two neighboring first pad 111 of binding component 10 is bigger, and the contraposition of permission is inclined
Shifting amount is bigger, such as Fig. 1 and binding component shown in Fig. 2, in the first sub- pad area 101 and the 5th sub- pad area 105
The first pad 111 and when being bound wait bind pad of display panel, can offset ranges it is maximum, then in binding component 10
When expanded by heating occurs, the first pad 111 far from binding 10 center of component, such as the first sub- pad area 101 and the 5th
When the first pad 111 in sub- pad area 105 is bound with the first pad 111 on display panel corresponding thereto, first
The contraposition offset of corresponding pad is easier to fall within the offset ranges of permission on pad 111 and display panel, no
It is also easy to produce and aligns the bad and bad some contingency questions of bring of contraposition.Optionally, binding component 10 is FPC.
The utility model includes multiple sons along first direction arrangement by the way that pad area, pad area are arranged on binding component
Pad area, and multiple first pads are set in every sub- pad area, and the position away from pad center position is remoter, in sub- pad area
The first adjacent pad between spacing it is bigger so that between adjacent first pad in binding component pad area both ends
Spacing is bigger, so that it is bigger away from the offset that the first remoter pad of pad center position allows, so that binding
When component expands due to itself or place environment temperature are excessively high etc., the first pad and display panel of component are bound
Offset when pad contraposition binding is fallen in as much as possible within the offset ranges of permission, avoids binding component to the maximum extent
Contraposition when being bound with display panel is bad, solves the contraposition of binding component and display panel by pad binding when not
Contraposition bad problem of the pad of the pad and display panel of good problem, especially binding component end positions in binding.
Embodiment two
Fig. 3 is a kind of structural schematic diagram for binding component that the utility model embodiment two provides, and the present embodiment is above-mentioned
On the basis of embodiment one, it is further provided a kind of optional binding component.
Optionally, sub- pad area is distributed in intermediate region 120 and two end regions 130 of binding component 10；Two end regions 130
Adjacent first pad 111 between spacing be greater than intermediate region 120 adjacent first pad 111 between spacing.
Specifically, the first pad 111 can be arranged in the intermediate region 120 of binding component 10 and two end regions 130.Because of binding
The swell increment of 10 liang of end regions 130 of component is big, and the swell increment of intermediate region 120 is small, then after binding component 10 expands, two
When first pad 111 of end regions 130 is bound with pad on display panel, offset can be larger, therefore two petiolareas are arranged
Spacing between adjacent first pad 111 in domain 130 is greater than the spacing between adjacent first pad 111 of intermediate region 120, then
When binding component 10 and display panel is bound, the offset of the first pad 111 allowed in two end regions 130 is larger,
And then it avoids causing on the first pad of end positions 111 and display panel since binding 10 end positions swell increment of component is excessive
Pad ties up the excessive caused bad problem of contraposition of timing offset.
Optionally, the first pad 111 for binding component 10 is used to be bound with the second pad being arranged on display panel,
Second pad is corresponded with the first pad 111 respectively；Fig. 4 is one on binding component provided by the embodiment of the utility model
