Specific embodiment
Existing flexible display panels are using laser cutting, and two big plate (array substrate and color membrane substrates) contrapositions are at position after box
Color membrane substrates laser cutting at terminal pin is more demanding, easily injures the cabling on array substrate face, cause to scrap and
The defects of reliability failures, this greatly influences the mass production and yields of flexible display panels.
Terminal pin position cabling, the function element on cutting line periphery or film layer etc. are not injured when being cut into small pieces for big plate,
After inventor completes various device architectures and liquid crystal orientating membrane on flexible substrates, the terminal pin on flexible color membrane substrates is carried out
Side is precut, be primarily due to flexible display be using laser cutting, two big plates (array substrate and color membrane substrates) contrapositions at
Being located at the color membrane substrates at terminal pin after box cannot be cut by laser, and can injure the cabling on array substrate face, and other regions are cut
It draws, can just cut at after box without cabling at secant.That is, in advance to the flexible color membrane substrates or flexible array for being not provided with binding area
The cutting region of substrate is cut, then flexible color membrane substrates and flexible array substrate contraposition after box at no longer needing to cutting region
It is cut, eliminates contraposition into the problem of easily area's contact conductor is bound in damage when cutting after box, but flexible display panels are good
Product rate is not still high, and product shows easily uneven defect occur, influences the mass production of flexible display panels.
Through inventor's test of many times, 1 ' stimulated light surplus of flexible base board generates local thermal stress, heat when discovery is cut by laser
Internal stress can not quick release and cause the film layer at 2 ' place of cutting line take the form of inclined plane protrusion 3 ' deformation defect, as shown in Figure 1, convex
3 ' the general very littles of height are played, the GAP after the opposite fitting of two large substrates only has 2 ~ 5 μm, and the protrusion 3 ' of part will lead to GAP at this
Increase, product shows uneven defect；And protrusion 3 ' results even in frame adhesive at this and can not adhere to the contact of two large substrates,
The problem of can not being bonded, this greatly influences the mass production and yields of flexible display.
Embodiment 1
To solve the above-mentioned problems, the present invention provides a kind of manufacturing methods of flexible base board comprising following steps:
Step A1, one first flexible layer 100 is formed on the first hard substrate.
First flexible layer 100 division has several first panel areas 110, each first panel area 110 include by
The cutting region 112 and non-cutting region 113 that first cutting line 111 separates；The non-cutting region 113 includes the first viewing area
1131 and surround the first adhesive area 1132 of first viewing area 1131.
The material of the hard substrate is preferred but is not limited to glass, such as alkali-free glass.The material of flexible layer includes organic
High molecular material preferably but is not limited such as PI, TAC；Usual thickness is about 50 ~ 100 μm.In order to realize the separation of flexible structure,
The supporting element of flexible base board need to often be used glass substrates as.It is bonded between glass substrate and flexible base board using organic viscose,
Organic viscose thickness is about 100 ~ 200 μm.Subsequent that flexible base board is separated from hard substrate, can be used has in 0 ~ 10 DEG C of environment
Machine viscose loses viscosity automatically and realizes removing, and UV illumination mode also can be used and lose viscosity realization removing.
Step A2, cutting compensation layer 120 is formed on first flexible layer 100, is divided into several 121 Hes of first area
Several second areas 122, wherein first cutting line 111 is located in the first area 121.

Fall the cutting region, so that binding area exposes convenient for binding.It is (hard with glass etc. typically, for hard display panel
Display panel of the matter substrate as loading plate), be after array substrate and color membrane substrates contraposition are at box, by preset cutting line,
Cutting region is cut away while cutting obtains several display panels, and the electrode cabling in binding area is not damaged substantially
Wound, this is mainly due to the characteristic of hard substrate, not instead of direct cutting hard substrate when cutting, first on its surface along cutting
Line is pre-cut crackle, and to rely on external force to break again disconnected.But if the cutting of existing hard display panel is pressed for flexible display panels
Mode realizes, then easily causes that damage causes to scrap and reliability is lost in laser cutting process to the contact conductor in binding area
The defects of effect.
The present invention in the manufacturing process of flexible display panels, in advance to be not provided with binding area flexible base board cutting area
Domain is cut, then flexible color membrane substrates and flexible array substrate contraposition are arranged at no longer needing to cut cutting region after box
The problem of in addition to contraposition at binding area's contact conductor is easily damaged when cutting after box；Meanwhile it making and cutting on flexible base board surface
Compensation layer is cut by laser again the cutting compensation layer that exposure development removes the bulging deformation on both sides at the first cutting line, then may be used
Height of projection is effectively reduced, exclude to cause the GAP at this to increase because of height of projection, so that product shows non-uniform defect；
Solving height of projection simultaneously causes frame adhesive at this two large substrates can not be contacted adherency, i.e., the problem of can not being bonded；It realizes
Flexible display panels mass production and raising production yield.
