Plate.
S150, each display panel of removal pad on light degradation alignment films.
Wherein, to ultraviolet-sensitive under ultraviolet light chain-scission degradation can occur for light degradation alignment films, so as to be gone
It removes.
Illustratively, the energy value range that light degradation alignment films are carried out with the available light irradiation of light degradation is 50mJ/
cm2-50000mJ/cm2。
Illustratively, Fig. 6 is the display panel planar junction of the light degradation alignment films on removal pad in the embodiment of the present invention
Structure schematic diagram；Fig. 7 is a kind of cross-sectional view in the B1-B2 directions along Fig. 6.Reference Fig. 6 and Fig. 7, non-display area NAA's
Light degradation alignment films 230 on pad 250 are removed, and follow-up pad 250 is facilitated to be electrically connected with external circuit.
S160, external circuits are bound by pad.
Wherein, pad is electrically connected by anisotropy conductiving glue and gold goal with external circuit, makes display panel in external circuit
Control is lower to realize display function.
The preparation method of array substrate provided in an embodiment of the present invention passes through the shape on the first motherboard and/or the second motherboard
Into light degradation alignment films, light degradation alignment films covering part or the pad being entirely located in the binding area of non-display area；Light is dropped
Disorientation film carries out light orientation；The dispenser method on the first motherboard or the second motherboard, to the first motherboard of box and the second motherboard；Then
Multiple display panels will be first cut into the first motherboard after box and the second motherboard, display panel includes being cut by the first motherboard
Array substrate and the color membrane substrates that are cut by the second motherboard；The light degradation then removed on the pad of each display panel takes
To film；External circuits are bound by pad afterwards again.Display panel is formed using first cutting, the rear light degradation orientation removed on pad
The process of film without using the complex and high cost mask plate of pattern and without large-scale exposure machine alignment equipment, can simplify
The preparation flow of display panel reduces cost, improves yield.
Optionally, step S110 includes：Light degradation orientation is formed on whole plate of the first motherboard and/or the second motherboard
Film.
Illustratively, Fig. 8 is a kind of existing display panel planar structure schematic diagram for forming light degradation alignment films；Fig. 9
To form another display panel planar structure schematic diagram of light degradation alignment films in the embodiment of the present invention.Reference Fig. 8 and Fig. 9,
It is illustrated for forming light degradation alignment films 330 on the first motherboard 310, illustratively shows to show with AA in Fig. 8 and Fig. 9
Show area.
Referring to Fig. 8, in the prior art, to ensure that viewing area AA is completely covered, while drop light by light degradation alignment films 330
The less covering conduction region of disorientation film 330 (illustrative, it may include pad and other conductive structures in binding area), leads to
Often control light degradation alignment films 330 exceed the width of viewing area AA (this width is also referred to as " light degradation alignment films extend out distance ")
For W1.In traditional light degradation alignment films coating method, small generation line (<G6) generally use letterpress mode, big generation line
(>G6) generally use inkjet printing mode, and with the development of display technology, it is desirable that the frame of display panel is more and more narrow, with
And the utilization rate of display panel is higher and higher, thus leads to 330 printing precision of light degradation alignment films by great challenge.It is practical raw
During production, since the diffusion control difficulty of light degradation alignment films 330 is big, light degradation alignment films 330 is caused to exceed viewing area AA
Part inevitably partly or entirely cover conduction region, so as to cause asking for above-mentioned conduction region and external circuit loose contact
Topic.In addition, using mask exposure remove the first motherboard 310 conduction region light degradation alignment films 330 during, there are above-mentioned
Preparation flow is complicated, it is of high cost, and yield risk is big the problem of.
With reference to Fig. 9, light degradation alignment films 330 cover whole plate of the first motherboard 310, you can the side covered using big plate full coat
Formula forms light degradation alignment films 330 on whole plate of the first motherboard 310, is coated to conduction region and (such as is shown in Fig. 4 or Fig. 7
Binding area in pad 250) light degradation alignment films 330 step S150 removals can be used, ensure the stability of product.Together
When, it need not consider that mask pattern designs in a manner that big plate full coat covers, no matter the substrate of that is, any product type is (illustrative
It is interpreted as the first motherboard or the second motherboard), can identical relief printing plate or ink jet designs pattern be used to be produced, improved
The convenience of light degradation alignment films coating, reduces production difficulty, greatly simplifies the production process of display panel, improves
Producing line efficiency, reduces cost.
Optionally, step S150 includes：Light degradation is only carried out to the light degradation alignment films on pad using shading module,
Middle shading module includes light source；It further includes when carrying out light degradation to light degradation alignment films or later：Binding area is heated.
Wherein, optionally, shading module may also include light-shielding structure, and light source is sent out using the light-shielding structure of shading module
Light carry out partial occlusion so that the light that light source is sent out only on pad light degradation alignment films carry out light degradation, without right
The light degradation alignment films production in the region (illustratively may include viewing area) on the corresponding display panel in position that light is blocked
It is raw to influence.
Meanwhile the light degradation process of light degradation alignment films of can accelerating is heated to binding area, further save the time into
This.
It should be noted that it is different according to the model of light degradation alignment films, when mode of heating goes light degradation alignment films
Except it is less efficient when, light degradation alignment films on pad can also be removed in a manner that cleaning is dissolved.
Illustratively, light source includes ultraviolet source and laser lamp.
Optionally, ultraviolet source may include high-pressure sodium lamp, ultraviolet LED lamp.
It should be noted that the present invention does not limit the specific type of light source, only need that light degradation alignment films can be carried out
Light degradation.Meanwhile the time of power to light source and light source irradiation does not limit, by adjusting the power and light source of light source
It the time of irradiation, can effective above-mentioned light degradation alignment films of light degradation.It wherein, can be by changing light to the adjustment of light source power
The routine adjustment mode such as source quantity and source layout's mode realizes that the present invention does not illustrate this, while do not limit.
