Flexible panel is bent according to form needed for 3D attaching process, such as shown in Fig. 2, the fringe region of flexible panel both sides is applied
Add damping, to execute bending operation.
Bending curvature K of the flexible panel after the bending operation2It can be equal in application of a surface operation (3D fitting behaviour
Make) after bending curvature K1, i.e. K1=K2.Certainly, bending curvature K of the flexible panel after the bending operation2It can also be more than
Its bending curvature K after application of a surface operation1, i.e. K1＜ K2, in this, the application can detect soft when bending curvature bigger
The quality of property panel, is more conducive to and flexible panel is avoided defect occur after 3D attaching process.
The application can utilize detection device shown in Fig. 2 to execute the bending and operate.In conjunction with shown in Fig. 2, the detection
Device includes pressure head 21, damping mechanism 22 and motor, and the front end face of the pressure head 21 is curved surface, and damping mechanism 22 is towards pressure head 21
Stitching surface be also curved surface, specifically, the stitching surface of damping mechanism 22 include positioned at middle part first level region and be located at
The front end face in the first bending region at edge, the pressure head 21 includes positioned at second horizontal zone at middle part and positioned at edge
Second bending region, the first level region and the second horizontal zone are setting up and down, it is described first bending region and second
Bending region is setting up and down, and the bending curvature in second bending region is less than or equal to the described first bending for bending region
Curvature.
In practical application scene, the damping mechanism 22 may include curved surface transparent cover plate 221 and for carrying song
The lower face of the detent mechanism 222 of face transparent cover plate 221, the curved surface transparent cover plate 221 is curved surface, the as pressure of damping mechanism 22
Conjunction face.
Detection device shown in Fig. 2 executes the principle that bending operates and process is as follows：
First, it will complete to be positioned on the front end face of pressure head 21 at the flexible panel 10 of box processing procedure, detent mechanism 222 will be bent
Face transparent cover plate 221 is fixed on the surface of pressure head 21；Then, pressure head 21 under motor promotion towards curved surface transparent cover plate 221
Mobile, the intermediate region of flexible panel 10 is contacted with the first level region at 221 middle part of curved surface transparent cover plate at first；Then, horse
Moved toward one another up to pressure head 21 is continued to press on towards curved surface transparent cover plate 221, pressure head 21 by the damping of curved surface transparent cover plate 221 and
It deforms upon, specifically, the fringe region of the second upward flexible panel in bending region 10 at 21 edge of pressure head, to be driven
The first bending region at the fringe region of flexible panel 10 and 221 edge of curved surface transparent cover plate contacts, until flexible panel 10 with
221 complete face paste of curved surface transparent cover plate is closed, at this point, the bending of the bending state of flexible panel 10 and curved surface transparent cover plate 221
State is identical, that is, the flexible panel 10 includes that the third horizontal zone positioned at middle part and the third positioned at edge are bent
Region, it is equal with the second bending bending curvature in region which bends region, wherein the third bends region and second curved
The bending curvature in folding area domain is above-mentioned bending curvature K2.So far, the bending operation is completed.
The position that pressure head 21 can also be arranged in the application immobilizes, the flexible panel 10 being attached on 21 front end face of pressure head
Position also immobilize, motor driven detent mechanism 222 moves down, and curved surface transparent cover plate 221 is driven towards flexibility with this
Panel 10 moves toward one another, and the fringe region of flexible panel 10 is deformed upon by the damping of curved surface transparent cover plate 221, thus with
221 complete face paste of curved surface transparent cover plate is closed, and completing the bending with this operates.
Wherein, the curved surface transparent cover plate 221 can be identical as the curved surface cover board needed for 3D attaching process, i.e., the application can
It is operated with carrying out the bending to flexible panel 10 using the curved surface cover board needed for 3D attaching process, bends curvature K at this time2It is equal to
The bending curvature K of application of a surface operation1.And as bending curvature K2More than the bending curvature K of application of a surface operation1When, 3D is bonded work
The bending curvature of curved surface cover board needed for skill is less than the bending curvature of the curved surface transparent cover plate 221.
In step s 13, in conjunction with shown in Fig. 2, damping mechanism 22 is removed, then by the flexible panel of bending 10 from pressure head 21
On remove, certainly, in order to ensure the bending effect stability of flexible panel 10, the application can keep curved surface transparent cover plate 221 with
Flexible panel 10 is in the state of complete face paste conjunction for a period of time.Then, flexibility of the lighting machine to bending may be used in the application
Panel 10 is illuminated, and checks whether flexible panel 10 defect occurs with this.The lighting machine can be considered as detection device shown in Fig. 2
Testing agency, certainly, in other embodiments, the application can also select other devices as the flexible panel 10 to bending
Carry out the testing agency of defect inspection.
The application is not intended to limit the concrete type for the defect that can be detected.For example, in the poly layer (polycrystalline of flexible panel 10
Silicon layer) since bending occurs in the application scenarios being broken, with poly layers of TFT, (Thin Film Transistor, film are brilliant
Body pipe) it is off, data drive signal cannot pass through the TFT and input pixel region connected to it, the pixel region
Position will appear the defects of bright spot, bright line.In this, can be examined by the way that whether detection flexible panel 10 bright spot or bright line occurs
Whether the flexible panel 10 for looking into bending there is defect, and the position of the bright spot and bright line is flexible panel 10 position of defect occurs
It sets.
If defect occurs in the flexible panel 10 of bending, the flexible panel 10 is carried out smooth processing by the application, then
Flexible panel 10 in formation state is repaired.In conjunction with shown in Fig. 2, due to curved surface transparent cover plate 221 and flexible panel
OCA (OpticallyClear Adhesive, optical cement) is not provided between 10, therefore the application can be easy to remove song
Face transparent cover plate 221 detaches flexible panel 10 and curved surface transparent cover plate 221, and flexible panel 10 is no longer influenced by curved surface transparency cover
The damping of plate 221 easily can become formation state from bending state.
If the flexible panel 10 of bending does not occur defect, the application uses it for 3D attaching process.
Based on above-mentioned, the application first executes bending operation to flexible panel 10, is equivalent to and is carried out before 3D attaching process
Simulation 3D fitting, then whether the flexible panel 10 detected after bending there is defect, so as to right before 3D attaching process
Flexible panel 10 carries out Quality Detection and is repaired to flexible panel 10 when there is defect, can avoid in 3D attaching process
The flexible panel 10 of bending can not be repaired later, with this it is advantageously ensured that shipment yield, avoids waste of material.
Detection process based on above-described embodiment and principle, the application can also realize that other curved surface elements are bonded work in 3D
Detection before skill, and the 3D being not limited between flexible panel and curved surface cover board is bonded.In this, the application also provides another
The detection method of embodiment.
Fig. 3 is the flow diagram of the detection method of the flexible piece of one embodiment of the application.As shown in figure 3, the flexibility
The detection method of part includes the following steps S31~S35.
