Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, is not whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of protection of the invention is belonged to.
Wherein, the size and shape of each structure does not reflect its actual proportions in accompanying 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, including：Substrate 01, is located at
Organic electroluminescence structure 02 on substrate 01, covers the thinner package film layer 03 of organic electroluminescence structure 02；Also include：Attach
In thinner package film layer 03 away from the first up-protective layer 04 of the side of organic electroluminescence structure 02, substrate 01 is attached at away from organic
First lower protective layer 05 of the side of EL structure 02；
As shown in Figure 2 a, the first up-protective layer 04 exceeds substrate 01 at least on the bending direction of principal axis 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 beyond the region where substrate 01 on bending direction of principal axis S；
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 direction of principal axis S
Region where substrate 01.
Above-mentioned flexible display panels provided in an embodiment of the present invention, including：Substrate, the organic electroluminescent on substrate
Structure, covers the thinner package film layer of organic electroluminescence structure.The flexible display panels also include：It is attached at the thinner package film layer back of the body
From the first up-protective layer of organic electroluminescence structure side, substrate is attached at away from the first of organic electroluminescence structure side
Lower protective layer；And first region of the up-protective layer at least on the bending direction of principal axis of flexible display panels where the substrate；With/
Or first region of the lower protective layer at least on bending direction of principal axis where the substrate.Protected using the first up-protective layer or first time
The flexible display panels problem that stress is concentrated at the edge of thinner package film layer in bending is avoided beyond the part of substrate in sheath,
Such that it is able to alleviate due to the problem of Crack Extension caused by flexible display panels bending.
In the specific implementation, in flexible display panels provided in an embodiment of the present invention, when the first up-protective layer 04 and
When one lower protective layer 05 at least exceeds the region at the place of substrate 01 on bending direction of principal axis S, the alleviation Crack Extension for playing
Effect is best.
In the specific implementation, because thinner package film layer is substantially will not be with the crackle on the parallel side of bending direction of principal axis
The bending for flexible display panels extends, and therefore, it can only the first up-protective layer or the first lower protective layer can only curved
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, because the stress when flexible display panels are in bending can be in the edge collection of flexible display panels
In, therefore when the first up-protective layer or the first lower protective layer are when the region where exceeding substrate on direction of principal axis is bent, equivalent to
Beyond the most edge for partially changing into flexible display panels, so as to concentrate on the stress concentration at thinner package film layer edge first originally
On up-protective layer or the first lower protective layer, therefore the first up-protective layer or the first lower protective layer exceed base on bending direction of principal axis
The width in the region where plate is bigger, more can effectively prevent crackle in thinner package film layer from being extended to viewing area.But, such as Fig. 2 c
Shown, the width W beyond the region where substrate 01 is more for the first up-protective layer 04 and/or the first lower protective layer 05, and flexibility is aobvious
Show that the frame of panel is wider, be unfavorable for narrow frame design.And the width W in the region where exceeding substrate 01 is too narrow, technique ratio
It is relatively difficult to achieve, therefore combine current manufacture craft and Anti-cracking extension effect, the first up-protective layer 04 and/or first time protection
Width W of the layer 05 beyond the region where substrate 01 on bending direction of principal axis S is at least 200 μm.Specifically, implement in the present invention
