Connection.The embodiment of the present invention in terms of existing technologies, is provided with and drives in the lower section of 3 Anodic figure 40 of planarization layer
The anode connection strap 41 that circuit layer 2 connects, and multiple regional areas of anode pattern 40 are and anode connection strap 41 below
It is electrically connected, so that plurality of positions can be powered by anode connection strap 41 in anode pattern 40, thus in anode pattern
When bending fracture, breaking portion still can provide electric signal by anode connection strap connected to it, and then greatly reduce fracture
The failure risk of partial anode pattern is conducive to the reliability for improving product.Below to the flexible display panels of the present embodiment
Realization details be specifically described, the following contents only for convenience of the realization details provided is understood, not implements this programme
It is necessary.
Specifically, the bending demand of the different display areas of flexible display panels may be different, such as the viewing area having
The bending degree that domain needs is larger, and the bending degree that some display areas need is smaller.It therefore, in practical applications, both can be with
Anode connection strap 41 is set for all anode patterns 40 in flexible display panels, or demand in flexible display panels
The biggish setting of the anode pattern 40 anode connection strap 41 of bending degree, and anode pattern lesser for the bending degree of demand 40
It can also be not provided with anode connection strap 41.It is connected for example, anode is arranged for the anode pattern 40 in flexible display panels central area
Item 41, without anode connection strap 41 is arranged for the anode pattern 40 of flexible display panels fringe region.
In the present embodiment, the shape of anode pattern 40 is, for example, rectangle, so without being limited thereto, in some instances, anode figure
Shape can also be the other shapes such as circle, pentagon.The structure of anode pattern 40 can be ITO/Ag/ITO (transparent Indium indium
Tin silver/transparent indium tin oxide) etc. three-layer composite structure.So without being limited thereto, in some instances, anode pattern can also be
The hybrid conductive layer that metal and transparent conductive film are formed.Alternatively, being reflecting electrode film layer in anode layer in some instances
When, which can be by silver (Ag), magnesium (Mg), aluminium (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium
(Nd), iridium (Ir), chromium (Cr) or their mixture are formed, and tin indium oxide (ITO) transparent conductive film, indium-doped zinc oxide
(IZO), zinc oxide (ZnO) or indium oxide etc. can be formed in the reflecting electrode film layer.The present embodiment is for anode pattern
Structure be not particularly limited, any anode construction that can be realized belongs to the protection scope of the present embodiment.
In the present embodiment, anode connection strap 41 can be for positioned at the closed ring connection strap of 40 lower section of anode pattern.Specifically
Ground, anode connection strap 41 can be the anode connecting line with one fixed width, and closed ring anode connection strap 41 is i other words anode
Between the various pieces of connection strap 41 without breakpoint, can mutual conduction, thus anode connection strap 41 need and corresponding sun
The driving circuit single-point of pole figure shape 40 connects, such as anode connection strap 41 (can also claim conductive mistake by a contact hole
Hole) it is connect with driving circuit, so as between simplified anode connection strap 41 and the driving circuit of corresponding anode pattern 40
Connection structure.It should be appreciated that anode connection strap 41 also may include the part of multiple disconnections, for example including two sub- connection straps,
There is one or more tie point, each sub- connection strap is separately connected corresponding anode between each sub- connection strap and anode pattern 40
The driving circuit of figure.Wherein, the driving circuit of anode pattern 40 can use film film transistor (Thin Film
Transistor, TFT), it so should not be as limit.
In the present embodiment, anode connection strap 41 can be bending shape, to be conducive to improve the resistance to of anode connection strap 41
Bending performance.In some instances, anode connection strap 41 or the straight-bar-shaped structure in rectangle.Anode connection strap 41 can be with
Using the preferable metal production of bending resistance, such as Ag (silver) or memorial alloy etc..Wherein, memorial alloy includes but unlimited
In Ultimum Ti, copper-based memory alloy etc..The excellent in mechanical performance of memorial alloy etc. has shape memory effect, superlastic
Property, the plurality of advantages of low-density, high intensity, high-damping etc., thus the bending resistance for the anode connection strap produced can be made more
It is good, it is not easy to break.So without being limited thereto, anode connection strap can also be using other various materials that can satisfy bending resistance requirement
Material production.
Please refer to a kind of 41 structure of closed ring anode connection strap of bending shape shown in Fig. 2.Specifically, anode connects
First straight segmentation 410 and multiple bending part 411 of the item 41 for example including multiple disconnections.Each first straight segmentation 410 is in rectangle point
Cloth, i.e., each first straight segmentation 410 are both formed on each side of preset rectangle.Two neighboring first straight segmentation 410 passes through respectively
Bending part 411 is connected, so that each first straight segmentation 410 and bending part 411 can connect into a bending convolution closing
Circular anode connection strap 41.The present embodiment is not specifically limited the quantity of anode connection strap 41, such as an anode pattern
Two anode connection straps 41 can also be correspondingly arranged.Specifically, bending part 411 is directly segmented 4110 and two for example including second
Tiltedly segmentation (4111,4112).First straight segmentation 410 is parallel with the second straight segmentation 4110 of connected bending part 411, and each first is straight
Two oblique segmentations (4111,4112) that the both ends of segmentation 410 pass through bending part 411 respectively are connected with the second straight segmentation 4110.Its
In, the straight segmentation of the second of bending part 411 is directly segmented 410 compared to first connected with bending part 411 far from anode connection strap 41
Center, i.e., each second straight segmentation 4110 is respectively positioned on each first parallel outside being directly segmented, and each second straight segmentation 4110 is also
In distributed rectangular.Therefore, each first straight segmentation 410 is considered as the inner ring of anode connection strap 41, and each second is directly segmented 4110
It is considered as the outer ring of anode connection strap 41.In practical applications, it can be each segmentation of anode connection strap 41 and anode
Figure 40 is electrically connected, and can also be only the inner ring of anode connection strap 41, i.e., each first straight segmentation 410 and anode pattern 40 are electrical
Connection.The present embodiment for anode connection strap concrete shape with no restriction, for example, each second straight segmentation also could alternatively be saw
Odontoid, or the second directly segmentation can also be cancelled, i.e., each first straight segmentation is directly connected by two oblique segmentations.The present embodiment
The shape of anode connection strap is not particularly limited, any shape that can satisfy bending resistance requirement is in the present embodiment
Protection scope in, such as bending part can also be arcuate structure.
Flexible display panels can also include the pixel confining layer 5 that is set on planarization layer 3 and be formed in pixel limit
