Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of flexible array substrate 1, flexible array substrate 1 comprises bendable folding area 10, wherein, bendable folding area 10 is as the term suggests refer to, region bent in array base palte, exemplary, as shown in Figure 1, the two ends of array base palte 1 are bent, namely have two bent regions 10 (as dotted line frame in figure the part that marks) between region for can not region be bent.Certainly, the present invention is not limited to the bent array base palte in two ends, such as, and the array base palte that all right arbitrary region is all bent, this array base palte just can be curling as picture scroll like this, and the bendable folding area 10 of this array base palte is exactly the region that this array base palte limits.Certainly, can also be the array base palte of other types, not do too much description at this.
Wherein, in Fig. 1, the vertical view of the part-structure of bendable folding area can see Fig. 2, flexible array substrate 1 along X-X ' in Fig. 2 to sectional view can see Fig. 3, flexible array substrate 1 comprises:
Substrate 11.
To be arranged on substrate 11 and the N kind metal pattern 12, N being positioned at bendable folding area 10 is more than or equal to 1.
Wherein, the distance of at least one metal pattern 12 correspondence in N kind metal pattern 12 is than in the scope of 0.9 to 1.1; The distance of metal pattern 12 correspondence is than the ratio for the distance (as shown in D1 in figure) between metal pattern 12 and flexible array substrate inside surface and the distance between metal pattern and flexible array substrate outside surface (as shown in D2 in figure).
Preferably, distance is than being 1.
It should be noted that, the distance that metal pattern described by the embodiment of the present invention is corresponding refers to that than in the scope of 0.9 to 1.1 this metal pattern is roughly in the stress neuter layer of flexible array substrate 1, makes the metal pattern not frangibility of flexible array substrate when there is bending in bendable folding area.Wherein, stress neuter layer refer to distance than the metal pattern in the scope of 0.9 to 1.1 when there is bending the tension that is subject to and compressive stress roughly equal, when distance than for 1 time, represent that distance is completely more equal with compressive stress than the tension that is subject to when there is bending of the metal pattern in the scope of 0.9 to 1.1.
Certainly, in the manufacturing of reality, because metal pattern has certain thickness, be therefore understandable that, the tension suffered by each position of metal pattern and compressive stress are not necessarily completely equal.Concrete, if the tension suffered by the center of guaranty money's metal patterns and compressive stress roughly equal.Wherein, stress is object when being out of shape due to external cause (stressed, humidity, change of temperature field etc.), and in object, produce interactional internal force between each several part, the internal force in unit area is called stress.Stress is vector.
You need to add is that, the flexible array substrate that the inside surface of the flexible array substrate described by the embodiment of the present invention refers to is near the one side (surface as shown in A in figure) of another block substrate (transparency carrier etc. as in the color membrane substrates in liquid crystal indicator, Organic Electricity laser display apparatus); The flexible array substrate that the outside surface of flexible array substrate refers to is away from the one side (surface as shown in B in figure) of another block substrate.

Due to organic insulator bending more resistance to than traditional inorganic insulation layer, therefore, inside metal pattern 12 and/or outside and the position contacted with metal pattern 12 arranges organic insulator, the bending characteristic of metal pattern 12 can be improved, ensure that the quality of display device.
Optionally, flexible array substrate 1 also comprises: the M layer inorganic insulation layer 14, M be arranged on substrate 11 is more than or equal to 1.
It should be noted that, the distance of metal pattern 12 can be realized by the position adjusting metal pattern 12 than the method in the scope of 0.9 to 1.1.
Concrete, organic insulator at least covers bendable folding area.At least one deck in M layer inorganic insulation layer at least covers the region except bendable folding area.
In the production application of reality, the thickness of organic insulator and inorganic insulation layer can be arranged according to the actual needs.Simultaneously, organic insulator is the need of the region covered except bendable folding area, or at least one deck in inorganic insulation layer will determine the position concrete according to metal pattern 12 the need of covering bendable folding area, as long as the distance of guaranty money's metal patterns 12 correspondence is than in the scope of 0.9 to 1.1, the present invention does not limit.
