【Specific embodiment】
In order to which the above-mentioned and other purposes of this announcement, feature, advantage can be clearer and more comprehensible, it is excellent that spy is hereafter lifted into this announcement
Embodiment is selected, and cooperates institute's accompanying drawings, is described in detail below.Furthermore the direction term that this announcement is previously mentioned, such as above and below,
Top, bottom, front, rear, left and right, inside and outside, side layer, around, center, it is horizontal, laterally, vertically, longitudinally, axial direction, radial direction, top layer or
Lowest level etc. is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand this announcement, and
It is non-to limit this announcement.
The similar unit of structure is to be given the same reference numerals in the figure.
Referring to Fig.1, an embodiment of this announcement provides the method for separation flexible circuit board and OLED display panel, including such as
Lower step.
Referring to FIG. 1 and FIG. 2, the flexible circuit board 100 and OLED display panel 200 that step 1, offer mutually fit.It is flexible
Circuit board 100 is curved including the first bending component 110, metal layer 120, the adhesion glue-line 130 and second set gradually from the bottom to top
Foldable assembly 140.130 binding metal layer 120 and second of glue-line of adhering bends component 140.First bending component 110 fits in OLED
The surface of display panel 200.
Specifically, the flexible circuit board 100 mutually to fit and OLED display panel 200 are placed on heavy industry platform 10,
Such as the flexible circuit board 100 mutually to fit and OLED display panel 200 are adsorbed and are positioned at heavy industry platform with vacuum slot
On 10.
Specifically, the material of metal layer 120 is copper foil.Due to attaching an entire metal layer in OLED display panel 200
120, therefore the heat that OLED display panel 200 and flexible circuit board 100 can be generated, be uniformly distributed scatter it is aobvious in entire OLED
Show panel 200 and flexible circuit board 100, avoids local ageing is too fast OLED display panel 200 is caused to show exception.
Specifically, the method for separating flexible circuit board and OLED display panel further includes providing polaroid 300, and OLED is shown
Panel 200 is set between polaroid 300 and the first bending component 110.
Specifically, flexible circuit board 100 further includes foam glue-line 150 and flexible unit 160.Foam glue-line 150 is set to
Between first bending component 110 and metal layer 120.Foam glue-line 150 is, for example, conducting foam glue-line or black foam glue-line.It is black
Color foam glue-line is to cohere OLED display panel 200 and cover the light leakage of OLED display panel 200.Flexible unit 160 is arranged
In on the second bending component 140.
Specifically, the electrostatic that OLED display panel 200 generates can pass through the first conductive bending component 110, conductive bubble
The electrode 162 that celloidin layer 150, metal layer 120, second are bent on component 140, flexible unit 160 and flexible unit 160 is released
It puts, improves the antistatic effect of OLED display panel 200.
Referring to Fig.1, Fig. 3 and Fig. 4, step 2 carry out the irradiation of laser 20 to adhesion glue-line 130, so that adhesion glue-line 130 loses
Go adhesiveness.
Specifically, for example, using laser 20 characteristic, select suitable wavelength, penetrate flexible unit 160 and second bending
The heat of component 140, laser 20 is absorbed by adhesion glue-line 130, so that adhesion glue-line 130 loses adhesiveness.
It should be noted that adhesion glue-line 130 can lose adhesiveness after the irradiation of laser 20, make to adhere glue-line 130 no longer
Binding metal layer 120 and the second bending component 140.Namely metal layer 120 is no longer bonded with the second bending component 140.
Referring to Fig.1 and Fig. 5, step 3, from metal layer 120 second bending component 140 separated.
Specifically, such as with the second bending component 140 of vacuum slot absorption make the second bending component 140 and metal layer
120 separation and by second bending component 140 be bent to first bending component 110 be generally aligned in the same plane, with facilitate check separate
Whether the second bending component 140 afterwards damages.
Specifically, flexible unit 160 is separated from metal layer 120.Such as with vacuum slot adsorption flexible component 160 and
So that flexible unit 160 is separated with metal layer 120 and is bent to flexible unit 160 and is located at same put down with OLED display panel 200
Face checks whether the flexible unit 160 after separating damages to facilitate.
It should be noted that due to glue-line 130 no longer the binding metal layer 120 and the second bending group of adhering after the completion of step 2
Part 140.Namely metal layer 120 is no longer bonded with the second bending component 140.It therefore in step 3, can be with the external force of very little
Second bending component 140 can be removed from metal layer 120.
Further, since flexible unit 160 is set on the second bending component 140, similarly, can be with the external force of very little
The flexible unit 160 being set on the second bending component 140 can be removed from metal layer 120.
So far, flexible circuit board 100 second bending component 140 and flexible unit 160 with OLED display panel 200 and
The metal layer 120 of flexible circuit board 100 separates, namely completes the separation of flexible circuit board 100 Yu OLED display panel 200.
The method of above-mentioned separation flexible circuit board 100 and OLED display panel 200, to the adhesion glue of flexible circuit board 100
Layer 130 carries out laser 20 and irradiates, so that it loses adhesiveness, and then separates the second bending component 140 of flexible circuit board 100,
The separation of flexible circuit board 100 Yu OLED display panel 200 can be completed without using biggish external force, success rate is high, can have
It is bad to generate peeling during effect prevents separation between each layer structure of flexible circuit board 100 because of stress, avoids because of glue of adhering
The adhesiveness of layer 130 damages the second bending component 140 because of separation, leads to entire OLED display scrap of the product, thus drops
Low production cost.
