Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, tool
Describe to body.Obviously, the described embodiment is only a part of the embodiment of the present invention, and not all technical solution.Based on this hair
Embodiment in bright, those skilled in the art's every other embodiment obtained without making creative work,
It shall fall within the protection scope of the present invention.
Embodiment one
The embodiment of the invention provides a kind of production methods of bending type flexible base board, are applied to flexible base board, the flexibility
Substrate is plate structure, the side edge surface including opposite first surface and second surface and the described two surfaces of connection, should
In method, flexible base board 3 is bent along bent area, and bent area is located at first surface.Specifically, shown in referring to Fig.1, this method is main
The following steps are included:
Step S100 reduces the viscosity of the bent area.
The step for there are a variety of implementation methods, such as by increase bent area surface contact angle, reduce bent area
Viscosity.
Optionally, such as pass through following sub-steps:
Sub-step S101a, in the bent area, fitting has the protective film 6 for reducing viscous effect；
Sub-step S101b waits specific duration to move back except the protective film 6；
Wherein, protective film 6 can for example use silicon systems adhesive；Specific duration is, for example, to be greater than one week.
When using above-mentioned sub-step, realize that the process for reducing bent area viscosity is as follows: referring to shown in Fig. 2, when flexible base
After plate 3 is removed from glass substrate, before pasting notacoria 1, first at the back side (first surface) of the corresponding substrate in bent area
It is bonded silicon systems protective film 6.This flexible base board 3 for being bonded silicon systems protective film 6 is stood into a period of time, is for example, greater than one week.
Referring to shown in Fig. 3, in this period, due to the characteristic that the adhesive of silicon systems has silicon to shift, the silicon in adhesive has been transferred to base
The bent area of plate, so that the contact angle on bent area surface increases, therefore the viscosity in the region becomes extremely low.Using These characteristics,
After taking the silicon systems protective film 6 off, then when pasting notacoria 1, since surface viscosity is extremely low, the colloid of bent area coating is viscous less than bending
Area surface.
Optionally, in another example by carrying out silicic acid anhydride to the bent area surface, it equally can achieve increase bending
Area's surface contact angle, to reduce the purpose of bent area viscosity.
Following step is also typically included before the step S100 to determine bent area position:
The second surface of the flexible base board 3 is bonded by step S102 with teleblem 4 so that the first end of the teleblem 4 with
The first end alignment of the flexible base board 3 and the second end of the flexible base board 3 stretch out the second end of the teleblem 4, described curved
Folding area is located at 3 extension of flexible base board close to the position of 4 second end of teleblem.
Referring to shown in Fig. 2, teleblem 4, the left end (first end) of teleblem 4 are bonded on the front (second surface) of flexible base board 3
It is aligned with the left end (first end) of flexible base board 3, the right end (second end) of flexible base board 3 stretches out the right end (second end) of teleblem 4.
Since reduction frame is in order to which the part that flexible base board 3 is stretched out teleblem 4 is folded into the back side, hence, it can be determined that bending position
In 3 extension of flexible base board at 4 right end of teleblem (second end).
It is worth noting that, the situation is only a kind of example of situation, in actual application, it is not limited thereto,
Such as: flexible base board 3 stretch out teleblem 4 part can in any one end, can also along substrate edges both sides, three while or when four
Exist simultaneously extension.
Step S200 is arranged glue material in the first surface and notacoria 1 is fitted in first table using the glue material 2
Face；
The step in, referring to shown in Fig. 3, glue material 2 is set at the back side (first surface) of flexible base board 3 first, then
Recycle the glue material 2 that notacoria 1 is fitted in 3 lower section (first surface) of flexible base board.Fig. 3 is also shown through fitting silicon systems protection
When the method for film reduces bent area surface viscosity the phenomenon that the silicon transfer 5 of bent area.Since the viscosity on bent area surface is extremely low, figure
Show that the glue material 2 in region 5 is hardly bonded with bent area.
In this step, glue material 2 can be coated in first surface, be also possible to individually, for by notacoria 1 and soft
Property substrate 3 first surface bonding one layer of material with stickiness, while being also possible to the included adhesive layer of notacoria 1, this is glutinous
Property layer notacoria 1 and the first surface can be binded.The present invention is not specially limited.
Step S300 cuts and removes glue material 2 corresponding with the bent area and bent area is left white by notacoria 1.
In this step, the method that cutting mode can for example use laser hemisect, adjusts laser energy, makes laser
Only cutting bent area pair glue material 2 and notacoria 1 without wounded substrate.Due to bonding notacoria 1 glue material 2 bent area hardly
With bent area surface bonding, so, can be easy to after laser hemisect by notacoria 1 and bond notacoria 1 residue glue removal.
Step S400 folds the flexible base board 3 along the bent area.
In this step, referring to shown in Fig. 4, corresponding glue material 2 is eliminated with after notacoria 1, and bent area is left white, and can be incited somebody to action
Flexible base board 3 is folded along bent area, stretching teleblem 4 is partially folded to substrate back (first surface), to reduce frame
The design of flexible display apparatus narrow frame is realized in region.Folded substrate is referring to Fig. 5.
Using the production method of bending type flexible base board 3 provided in an embodiment of the present invention, with existing when pasting notacoria 1
By the way of segmented conformable, the technology that bent area is available is compared, and includes at least following advantage:
Segmented conformable precision is avoided to be difficult to ensure, bonding zone notacoria 1 is narrow high to abutted equipment requirement and segmentation patch
The problem of technique takes long time is closed, increases the effective display area domain of flexible display apparatus, reduce frame region, to realize flexibility
The design of display device narrow frame reduces the requirement to abutted equipment and shortens operation simultaneously under the premise of guaranteeing Anawgy accuracy
Duration.
