Blank, each organic layer is deposited with using mask plate, accurate mask plate and high accuracy mask plate according still further to the region delimited, finally press
According to the shape cutting being pre-designed, the cutting free degree is low.Multigroup high accuracy mask plate is needed to use in preparation process, technique is multiple
It is miscellaneous, it is more expensive to manufacture.Additionally, when cutting separation is done, because glass substrate hardness is high, it is necessary to reserved larger cutting is empty
Between, substrate utilization is low.If preparing special-shaped screen, it is necessary to be directed to the screen shape custom mask version of needs, accurate mask
Version and high accuracy mask plate, not only technological process is long, preparation cost and its costliness.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome the difficult defect of opposite sex screen body cutting in the prior art,
So as to provide a kind of OLED screen body that can freely cut, as a result of flexible conductive base plate, can not only cut as needed
For variously-shaped, and photoetching process is not needed in preparation process, it is only necessary to which common mask plate, technological process is short, cost
It is low.
Further, present invention also offers a kind of OLED, it uses the above-mentioned OLED screen body that can freely cut to cut
The OLED screen simple grain to be formed binding conductive lead wire encapsulation is cut to form.
Further, present invention also offers the preparation method of above-mentioned OLED.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of OLED that can freely cut, including flexible conductive base plate, entirety that superposition is set continuously cover flexible

Luminescent layer, organic function layer and cathode film layer only need to use same group of common mask plate in mode, therefore preparation process,
Need not be using accurate mask plate and high accuracy mask plate, and traditional OLED at least needs to use accurate mask during being deposited with
Version and high accuracy mask plate, because high accuracy mask plate is expensive, therefore preparation cost is substantially reduced.Additionally, often changing one
Group mask plate is accomplished by once aligning process, and contraposition every time all inevitably occurs error, therefore repeatedly bit errors product
It is tired, reduce product yield.And the application only needs to one group of common mask plate, it is not necessary to repeatedly contraposition, therefore to greatest extent
Error is reduced, yield is improve.
3rd, for preparing special-shaped screen, the scheme of the application has significant advantage, is characterized in particular in, and the application is only needed to
Can be prepared using common mask plate, and traditional handicraft not only needs to make design shape by lithography in advance, in addition it is also necessary to according to preboarding
Shape customizes corresponding mask plate, special-shaped mask plate, special-shaped precision mask plate and special-shaped high accuracy mask plate valency in preparation process
It is expensive for the more common mask plate of lattice, manufacturing cost is virtually increased, and the scheme of the application is only needed to using existing
Equipment can processing.
4th, during the OLED that the application preparation can freely cut, it is not necessary to be individually deposited with anode film layer, it is not necessary to
Photoetching process is carried out according to the shape being pre-designed, two processing steps are saved on the basis of original technique, further letter
Change preparation technology, reduce manufacturing cost.
5th, the substrate of OLED screen body of the invention need not reserve cutting white space, therefore light-emitting area ratio is big.Enter
One step ground, lead uses two-sided bonding mode, shields internal portion without cabling, and actual only have that bonding region is luminous to be blocked, edge without
Not light-emitting zone.
