As shown in Figure 1 to Figure 2, in an embodiment of the present invention, display module 100 includes substrate 110, is formed in substrate
Anode layer and several insulated columns 150 of formation on the anode layer on 110.Wherein, anode layer is formed in including several
On substrate 110 and the anode strap 130 that is parallel to each other；Several insulated columns 150 are arranged in parallel, and insulated column 150 and anode
Bar 130 is vertically arranged.
It should be noted that display module 100 further includes the structures such as OLED material, insulating layer, cathode layer, these structures with
Structure of the prior art is no different, and details are not described herein again.
Specifically, anode strap 130 include some sub- anodes 131 distributed along its length and several by phase
The conduction element 133 of the adjacent sub- conducting of anode 131 connection.Wherein, the pliability of conduction element 133 is better than the pliability of sub- anode 131.
The pliability of conduction element 133 be better than sub- anode 131 pliability, i.e., conduction element 133 compared to sub- anode 131 more resistant to
Bending, the change of this performance can depend on being formed the performance of the material of corresponding construction, can also depend on corresponding construction
Change in size；This conduction element 133 resistant to bending used in the present invention can reduce anode when display module 100 is bent
The folding s tress of bar 130, prevents anode strap 130 to be broken；So as to it is advantageously ensured that anode strap 130 is conductive smooth, effectively avoid showing
Showing device display is abnormal.
It is identical with the form for forming pixel region in conventional art between two neighboring insulated column.In the present invention, it is sub
Anode 131 is located fully or partially between two adjacent insulated columns, and the sub- anode structure between two neighboring insulated column
Into corresponding pixel region.One of them sub- anode forms the anode in a single pixel region 170.
In the present embodiment, the center of sub- anode 131 is located on the plane of symmetry of two neighboring insulated column 150.It is so that sub
Anode 131 is overlapped with the center in single pixel region 170；The length of sub- anode 131 can be made smaller, i.e., so that conduction element 133
Length it is longer so that the bending resistance of anode strap 130 is more preferable.Certainly, the center of sub- anode 131 is not limited to this, also
The plane of symmetry of two neighboring insulated column 150 can be deviateed.
On the premise of sub- anode 131 can form the anode of single pixel, the length of conduction element 133 is not limited, energy
Enough meet technological requirement.Such as the length of sub- anode 131 can be made smaller, i.e., so that the length of conduction element 133 is longer, from
And make it that the bending resistance of anode strap 130 is more preferable.And obviously, conduction element 133 is longer, and the buckle resistance of anode strap 130 is stronger.
It should be noted that the length direction of sub- anode 131 is identical with the length direction of anode strap 130；Sub- anode 131
Width is identical with the width of anode strap 130, and identical with the length direction of insulated column 150.The conduction element 133
Length direction is identical with the length direction of sub- anode 131, and width is identical with the width of sub- anode 131.
Preferably, in the present embodiment, conduction element 133 is completely covered in projection of the insulated column 150 on substrate 110.It is located at
Anode strap 130 between insulated column 150 is sub- anode 131, so as to ensure the light-emitting area of single pixel.It is more highly preferred to
Ground, the length of conduction element 133 are equal to the width of insulated column 150, and in other words, sub- anode 131 is located at two adjacent insulated columns 150
Between, and the length of sub- anode 131 is equal to the distance between two neighboring insulated column 150.In this way, it can guarantee that single pixel
On the premise of light-emitting area so that the pliability bigger of anode strap 130, bending resistance are stronger.
In the present embodiment, sub- anode 131 is tin indium oxide (ITO) sub- anode.Certainly, sub- anode 131 is not limited to indium oxide
Tin anode, can also be indium zinc oxide (IZO) sub- anode etc..
133 one side of conduction element needs to increase the bending resistance of anode strap 130, on the other hand also to guarantee to make adjacent
