The arbitrary and all of combination of the Listed Items of pass.
A kind of flexible display 100 of one preferred embodiment of the present invention, the flexible display 100 is by following preparation method systems
Form, the preparation method is comprised the following steps：
S11：The surface that transparent substrates are used for coated with adhesive is surface-treated so that the surface of transparent substrates is in thin
It is aqueous.
In this step, by being surface-treated on transparent substrates 110 so that the surface of transparent substrates 110 is in thin
It is aqueous.And then facilitate follow-up tack coat 120 to peel off from transparent substrates 110.In more detail, on the surface of above-mentioned transparent substrates
Coating hydrophober, such as so, the surface for coating the transparent substrates of hydrophober is just in hydrophobicity, and above-mentioned hydrophober can be diformazan
Base silicone oil, but as long as the table surface of its transparent substrates 110 can be made in hydrophobic hydrophober, reaches the goal of the invention of the present invention
, here of the present invention is simultaneously not construed as limiting.
S12：In the side of transparent substrates uniformly coated with adhesive, to form tack coat.
As shown in Fig. 2 the surface coating in the transparent substrates 110 of one layer of hydrophober of above-mentioned coating is evenly coated with binding agent
120, the binding agent 120 includes polyurethane, is mainly used for for follow-up flexible substrate 140 being bonded in above-mentioned transparent substrates 110
Surface.Usually, what above-mentioned binding agent 120 was coated in the surface of transparent substrates 110 connects ectocentral position, and not exclusively covers
The surface of whole transparent substrates 110 is covered, in order to subsequent cure agent coating.
S13：Curing agent is coated on the tack coat, the tack coat for making the contact curing agent solidifies.
In this step, curing agent 130 (such as crosslinking agent) is coated on above-mentioned binding agent 120, will in present embodiment
Above-mentioned curing agent 130 is coated in the surrounding of the close marginal position of above-mentioned binding agent 120, and the curing agent 130 includes polymethyl
Sour methyl esters, it is mainly used in being contacted with above-mentioned binding agent 120, in detail, binding agent 120 formed it is outermost one circle with
Curing agent 130 can solidify within a short period of time after contacting, wherein the solidification width of the tack coat is 80-120um, in binding agent
Interior between 120 no completely crued this section, polymer thin film of the subsequent coated on the surface of tack coat can consolidating with binding agent 120
Change, make flexible substrate 140 be bonded in the surface of above-mentioned transparent substrates 110.
Certainly, above-mentioned curing agent 130 can be also coated in the whole surface of above-mentioned binding agent 120, as long as this can be reached
The goal of the invention of invention, the present invention is not construed as limiting to this.
S14：In the uniformly coated polymer solution of the tack coat, to form flexible substrate.
Before above-mentioned binding agent 120 is not fully cured, the upper surface of the tack coat formed in above-mentioned binding agent 120
Polymer solution is evenly coated with, then such as PI solution can be sent in high temperature oven, carry out at high-temperature heating
Reason, solidifies polymer solution and forms flexible substrate 140, i.e. flexible substrate, and the coating method of polymer solution can be with

The characterisitic parameters such as thickness, uniformity and surface roughness that liquid is coated.
S15：Barrier layer 150, tft array layer 160, oled layer 170 and encapsulated layer are sequentially formed in the flexible substrate
180。
Because the water oxygen transmitance of flexible substrate 140 is high, the stability and service life of OLED are had seriously
Affect, so in this step, need to form barrier layer 150 in flexible substrate 140, to prevent water oxygen from passing through, device is protected
Shield, used as preferred embodiment of the invention, the barrier layer 150 is the alternating structure that organic material/inorganic material is formed, or
The alternating structure that person's inorganic material/inorganic material is formed.Preferably, the organic material/inorganic material alternating structure is
parylene/SiNx/parylene/SiNx；Further, the inorganic material/inorganic material alternating structure is SiNxSiO2/
SiNx.Then the tft array 160 for driving flexible display device is made on barrier layer 150, such as Oxide-TFT, according to
The difference of TFT technological temperatures, needs from the different flexible substrate material of heat resistance.Then each layer organic material and electricity are deposited with
Pole material, makes OLED display device 170, and by tft array layer 160 and oled layer 170 AMOLED layers are constituted, and finally makes encapsulation
Layer 180, plays the impact for protecting flexible display from steam, oxygen, dust and stress.
S16：Another side surface of transparent substrates is exposed, so that the flexible substrate fails because of curing agent solidification
Separate with the transparent substrates.
After the completion of above-mentioned element manufacturing, the back side of transparent substrates 110 can be exposed, usually, the transparent substrates
110 is glass substrate, for example, the back side of transparent substrates 110 is exposed using ultraviolet, and light enters transparent substrates 110
The back side, because transparent substrates 110 can be such that light enters in it, and then exposes to and is cured positioned at the positive of transparent substrates 110
The tack coat of agent solidification, at this moment, due to being irradiated by light, curing agent 130 fails, and then the tack coat for causing to be cured is saturating with this
Photopolymer substrate 110 and flexible substrate are separated, and flexible display just can be cut and be peeled off by such staff along line of cut easily
Get off, wherein, tack coat is located adjacent to not being cured for the middle position of transparent substrates 110, and the surface of transparent substrates 110
With certain hydrophobicity, transparent substrates 110 are poor with the cementability of the zone line of adhesive linkage, so make binding agent 120 with
Flexible substrate departs from together transparent substrates, so when in follow-up flow chart as also needed to position OLED display device
When, the binding agent 120 may be repeated and use.
By the preparation method of above-mentioned flexible display, flexible substrate can be made easily to separate with above-mentioned transparent substrates, be simplified
Production technology, and avoid in traditional processing technology, using laser make flexible substrate that substantial amounts of particle is produced because of carbonization, and then
The pollution to OLED display is avoided, the yield of flexible display is improve.
Another preferred embodiment of the present invention discloses a kind of flexible display, and the flexible display is by above-mentioned embodiment
In the preparation method of flexible display be made.
The preparation method that above-mentioned flexible display passes through above-mentioned flexible display, can make flexible substrate easily with above-mentioned printing opacity
Substrate is separated, it is to avoid in traditional processing technology, is made flexible substrate that substantial amounts of particle is produced because of carbonization using laser, and then is kept away
Exempt from the pollution to flexible display, improve the yield of flexible display.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more concrete and detailed, but and
Can not therefore be construed as limiting the scope of the patent.It should be pointed out that for one of ordinary skill in the art comes
