Specific embodiment
Carry out the various exemplary embodiments of detailed description of the present invention now with reference to attached drawing.It should also be noted that unless in addition having
Body explanation, the unlimited system of component and the positioned opposite of step, numerical expression and the numerical value otherwise illustrated in these embodiments is originally
The range of invention.
Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to the present invention
And its application or any restrictions used.
Technology, method and apparatus known to person of ordinary skill in the relevant may be not discussed in detail, but suitable
In the case of, the technology, method and apparatus should be considered as part of specification.
It is shown here and discuss all examples in, any occurrence should be construed as merely illustratively, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
In order to promote the performance of display panel, inventor has carried out following research to display panel in the prior art:
Referring to Figure 1, Fig. 1 is a kind of planar structure schematic diagram for display panel that the prior art provides, specifically, Fig. 1
Show the planar structure schematic diagram of the binding area FF of display panel.As shown in Figure 1, a kind of display panel that the prior art provides
In, fanout area FF includes pad 01 and plain conductor 02, and pad 01 is for binding flexible circuit board (not shown), pad 01
Including metal portion 011 and electrode portion 012.Metal portion 011 is directly electrically connected with the metal routing 02 on display panel, electrode portion
012 is electrically connected by the way of via hole with metal portion 011, and flexible circuit board is directly bound in electrode portion 012.
The setting method of the pad for this "eight" shape that the prior art uses, enables to the lower frame of display panel more
It is narrow, but the area limitation such as smaller due to pad 01 by narrow frame, fanout area, the length of the electrode portion 012 of setting is shorter,
So that flexible circuit board and the accessible area of electrode portion 012 become smaller, so as to cause the contact of flexible circuit board and electrode portion 012
Effect is poor；Again since in the high temperature environment, display panel is different with the coefficient of expansion of flexible circuit board, the position of electrode portion 012
Set may and room temperature in the case of there are certain deviation, so that flexible circuit board and electrode portion 012 can not be bundled in one well
It rises, further such that the binding effect of flexible circuit board and electrode portion 012 is deteriorated, influences the reliability of display panel signal transmission
With stability.
In view of the above technical problems, the invention proposes a kind of display panel and display devices, about provided by the invention
The embodiment of display panel and display device, it is described in detail below.
Fig. 2-Fig. 3 is referred to, Fig. 2 is a kind of planar structure schematic diagram of display panel provided in an embodiment of the present invention, Fig. 3
It is a kind of the schematic diagram of the section structure of the display panel along hatching XX ' of Fig. 2 offer.As Figure 2-3, the present invention provides one kind
Display panel, comprising: underlay substrate 1；Area B is bound, binding area B includes multiple pads 2, and pad 2 includes the first sub-portion 21 and the
Two sub-portions 22, the first sub-portion 21 are located on underlay substrate 1, and the second sub-portion 22 is located at one that the first sub-portion 21 deviates from underlay substrate 1
Side, in the same pad 2, the first sub-portion 21 is identical with the extending direction of the second sub-portion 22, and the first sub-portion 21 is in underlay substrate 1
Orthographic projection at least partly overlaps with the second sub-portion 22 in the orthographic projection of underlay substrate 1, and the first sub-portion 21 has the first length L1,
There is second sub-portion 22 second length L2, the second length L2 to be greater than the first length L1, and display panel is close to the side of binding area B
Edge is first edge W1, and the first sub-portion 21 is first end H1, first end H1 and first close to the end of first edge W1
The distance of edge W1 is first distance D1, and the second sub-portion 22 is the second end H2, the second end close to the end of first edge W1
H2 is second distance D2 at a distance from first edge W1, and second distance D2 is less than first distance D1.Optionally, on display panel also
Including a plurality of signal wire 4, signal wire 4 is electrically connected with the first sub-portion 21.
Specifically, as shown in Fig. 2-Fig. 3, in display panel provided in this embodiment, pad 2 includes the first sub-portion 21 and the
Two sub-portions 22, the second sub-portion 22 cover the first sub-portion 21, and the first sub-portion 21 is directly electrically connected with signal wire 4,22 He of the second sub-portion
Electronic building brick (not illustrating in figure) is electrically connected, for binding electronic building brick.Second sub-portion 22 can play connection function, reduce electricity
The distance between first sub-portion 21 of sub-component and weldering；Also, electronic building brick is tied to display panel usually using conducting resinl, passes through
Suitable material is selected to make the second sub-portion, the more excellent performance that the second sub-portion 22 and conducting resinl can be made to be electrically connected makes electronics
The electrical connection of component and pad 2 is relatively reliable.
It should be noted that the extending direction of pad 2 can be not exactly the same in display panel provided in this embodiment,
A kind of calculation of first distance D1 and second distance D2 can be such that first end H1 is parallel with first edge W1, first
Distance D1 refers to the first end H1 of the first sub-portion 21 at a distance from first edge W1, and the second end H2 is also flat with first edge W1
Row, second distance D2 refer to the second end H2 of the second sub-portion 22 at a distance from first edge W1.
