Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, is not whole embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
Wherein, the size and shape of each structure does not reflect its actual proportions in attached drawing, and purpose is schematically illustrate hair
Bright content.
A kind of flexible display panels provided in an embodiment of the present invention, as shown in Fig. 2 a to Fig. 2 c, comprising: substrate 01 is located at
Organic electroluminescence structure 02 on substrate 01 covers the thinner package film layer 03 of organic electroluminescence structure 02；Further include: it attaches
Deviate from the first up-protective layer 04 of 02 side of organic electroluminescence structure in thinner package film layer 03, is attached at substrate 01 away from organic
First lower protective layer 05 of 02 side of EL structure；
As shown in Figure 2 a, the first up-protective layer 04 exceeds substrate 01 at least on the bending axis direction S of flexible display panels
The region at place；
Or as shown in Figure 2 b, the first lower protective layer 05 is at least on bending axis direction S beyond the region where substrate 01；
Or as shown in Figure 2 c, the first up-protective layer 04 and the first lower protective layer 05 at least exceed on bending axis direction S
Region where substrate 01.
Above-mentioned flexible display panels provided in an embodiment of the present invention, comprising: substrate, the organic electroluminescent on substrate
Structure covers the thinner package film layer of organic electroluminescence structure.The flexible display panels further include: be attached at thinner package film layer back
The first up-protective layer from organic electroluminescence structure side is attached at substrate deviates from organic electroluminescence structure side first
Lower protective layer；And first up-protective layer at least in the bending axis direction of flexible display panels beyond the region where substrate；With/
Or first lower protective layer at least in bending axis direction beyond the region where substrate.It is protected using the first up-protective layer or first are lower
In sheath beyond substrate part avoid flexible display panels bending when stress thinner package film layer the problems in edge collection,
So as to alleviate the problem of being bent caused crack propagation due to flexible display panels.
In the specific implementation, in flexible display panels provided in an embodiment of the present invention, when the first up-protective layer 04 and
One lower protective layer 05 at least when on being bent axis direction S beyond the region where substrate 01, the alleviation crack propagation that plays
Effect is best.
In the specific implementation, since thinner package film layer is substantially will not be with the crackle on the parallel side of bending axis direction
The bendings of flexible display panels extend, therefore, can be only curved with only the first up-protective layer or the first lower protective layer
Beyond the region where substrate on crankshaft direction, certain first up-protective layer or the first lower protective layer can also be in entire surfaces
Beyond the region where substrate, it is not limited thereto.
In the specific implementation, since the stress when flexible display panels are in bending can be in the edge collection of flexible display panels
In, thus when the first up-protective layer or the first lower protective layer on being bent axis direction beyond the region where substrate when, be equivalent to
Beyond the most edge for partially changing into flexible display panels, so that the stress for concentrating on thinner package film layer edge originally concentrates on first
On up-protective layer or the first lower protective layer, therefore the first up-protective layer or the first lower protective layer exceed base in bending axis direction
The width in the region where plate is bigger, more can effectively prevent crackle in thinner package film layer and extends to display area.But such as Fig. 2 c
Shown, the width W of the first up-protective layer 04 and/or the first lower protective layer 05 beyond the region where substrate 01 is more, and flexibility is aobvious
Show that the frame of panel is wider, is unfavorable for narrow frame design.And the width W beyond the region where substrate 01 is too narrow, technique ratio
