Embodiment
Specifically illustrate execution mode of the present utility model below in conjunction with accompanying drawing, accompanying drawing is only for reference and use is described, does not form the restriction to the utility model scope of patent protection.
As shown in Figure 1, the present embodiment provides a kind of flexible AMOLED display panel structure, comprise first substrate 1 and second substrate 2, second substrate 2 is cover sheet, comprise viewing area 11 on first substrate 1, non-display area 12, non-display area 12 is distributed in viewing area 11 surrounding and symmetrical, each end points of the controller connecting interface 13 on non-display area 12 connects each data wire 14 in viewing area 11 by metal routing structure 3, described metal routing structure 3 comprises bending routing region 31 and fan routing region 32, metal routing in every bar bending routing region 31 and the metal routing in fan-shaped routing region 32 connect one to one.
In the present embodiment, the metal routing bent in routing region forms via hole through etching.Preferably, described via hole is the shape such as regular hexagon or triangle.
The course of work of the present utility model is:
First depositing insulating layer material on display base plate 1, then many strip metals cabling is deposited, this metal routing structure 3 is between the control unit interface and viewing area 11 of non-display area 12, be divided into bending routing region 31 and fan-shaped routing region 32, and the metal routing in every bar bending routing region 31 and the metal routing in fan-shaped routing region 31 connect one to one, then exposure is adopted, development, the technology mode of etching carries out borehole to the metal routing in bending routing region 31, a layer insulating is deposited afterwards on metal routing, this borehole shape comprises regular hexagon, triangle etc., make via hole at the 31 pairs of metal routings in bending routing region like this can improve the adhesive capacity between different materials and accelerate metal routing institute and produce the lost of heat, reduce bending region trace resistances thus the generation of minimizing heat, according to metal routing width in bending region and every root metal routing the trace width size comprised between adjacent two via holes determine the size of via hole.
