It, will not be to 601 He of the first backboard section since the first backboard section 601 and the second backboard section 602 are symmetrical when axis 603 is bent
Second backboard section 602 plays bending function.Therefore, the first backboard section 601 and the second backboard section 602 will not be bent and be drawn
It stretches, avoids plastic deformation.In other embodiments, the cross-sectional shape of the first backboard section 601 and the second backboard section 602
It can be asymmetric；The cross-sectional shape of first backboard section 601 and the second backboard section 602 includes triangle, rectangle, diamond shape, axis pair
At least one of the hexagon of title, axisymmetric octagon or irregular figure；The application is not construed as limiting this.
It should be noted that the backboard 60 in display device 6 can be the corresponding backboard section of any of the above-described embodiment, tool
Body please refers to Fig.1~Fig. 5 and relevant verbal description, details are not described herein.
Be different from the prior art, backboard is divided into multiple backboard sections by the application, when display device is bent, backboard section due to
It does not stretch mutually each other, it is possible to reduce stretching when display device is bent to backboard becomes to avoid backboard that plasticity occurs
Shape can keep the display effect of display panel so that backboard fold does not occur after display device bending.
It is the cross-sectional view of the application display device second embodiment refering to Fig. 7, Fig. 7.
As shown in fig. 7, display device 7 includes the plastic layer 71 being sequentially stacked, backboard 70, panel layer 72, layer of polarizer 73
And cover layer 74, it is bonded by binder 75 between adjacent two layers.Panel layer 72 includes the display panels such as LCD and OLED, this
Application is not construed as limiting this.
In present embodiment, backboard 70 includes the first backboard section 701, the second backboard section 702 and third backboard section 703,
First backboard section 701, the second backboard section 702 and third backboard section 703 are distributed along the surface for being parallel to backboard 70, second back of the body
Plate section 702 is between the first backboard section 701 and third backboard section 703.First backboard section 701, the second backboard section 702 and
The material of three backboard sections 703 is PET (polyethylene terephthalate, polyethylene terephthalate), and first
The thickness of backboard section 701, the second backboard section 702 and third backboard section 703 is 75um.In other embodiments, first
The material of backboard section 701, the second backboard section 702 and third backboard section 703 may be PI (Polyimide, polyimides)
Equal materials；First backboard section 701, the second backboard section 702 and third backboard section 703 can also use different materials；First
The thickness of backboard section 701, the second backboard section 702 and third backboard section 703 may be other numerical value；First backboard section 701,
The thickness of second backboard section 702 and third backboard section 703 can also be different, and the application is not construed as limiting this.
In present embodiment, the side contact surface shape of the first backboard section 701 and the second backboard section 702 is complementary, mutually pastes
Splice grafting touches；The other side contact surface shape of third backboard section 703 and the second backboard section 702 is complementary, is bonded to each other contact, i.e., first
It is disconnected from each other between backboard section 701, the second backboard section 702 and third backboard section 703.Due to the first backboard section 701,
The contact surface shape of two backboard sections 702 and third backboard section 703 is complementary and is bonded to each other contact, therefore, when backboard is not by curved
When folding, three backboard section shape complementations can form a complete plane, and support and protective effect are played to display layer 72；When
When backboard is bent along central axes 704, three backboard sections do not stretch mutually, can be plastically deformed to avoid backboard, and the
Two backboard sections 702 are bent to form a circular arc to protect and support display layer 72.In another embodiment, two adjacent back ofs the body
The material that can also be more than backboard section by elasticity between the contact surface of plate section is fixed.It is more high-elastic between two adjacent backboard sections
The material of property can make backboard when stretching same length, to the drawing force smaller of two adjacent backboard sections, to avoid
Backboard plastic deformation.
In present embodiment, the first backboard section 701, the second backboard section 702 and third backboard section 703 cross-sectional shape
It is rectangle, and the first backboard section 701 and third backboard section 703 are distributed relative to 704 axial symmetry of central axes of backboard 30.When aobvious
It, will not be to first since the first backboard section 701 and third backboard section 703 are symmetrical when showing device 7 is bent along central axes 704
Backboard section 701 and third backboard section 703 play bending function.Therefore, the first backboard section 701 and third backboard section 703 will not be by
It is stretched to bending, avoids plastic deformation.In other embodiments, the first backboard section 701 and third backboard section 703 also may be used
With asymmetry；First backboard section 701 and the cross-sectional shape of the second backboard section 702 and third backboard section 703 include triangle,
At least one of rectangle, diamond shape, axisymmetric hexagon, axisymmetric octagon or irregular figure, the application to this not
It is construed as limiting.
Further, the length of the second backboard section 702 meets the relationship as shown in formula (1),
L=π R (1)
Wherein, L is the length of the second backboard section 702, and R is the crooked process radius of backboard 70.It should be noted that backboard 70
Crooked process radius according to the display device 7 crooked process radius determine.If for example, the crooked process radius of backboard 70 be 3mm, the second backboard section
702 length is 9.42mm, if the crooked process radius of backboard 70 is 5mm, the length of the second backboard section 702 is 15.7mm, first
Backboard section 701 and third backboard section 703 are equal, the first backboard section 701, the length of the second backboard section 702 and third backboard section 703
The sum of degree is backboard total length.When display device 7 is bent along central axes 704, the second backboard section 702 is bent to a circular arc,
And maximum can be bent to a semicircle, the bending part of panel layer 72 that can be with effective protection and support thereon.In other implementations
In mode, the length of the second backboard section 702 may be other calculations, but need to ensure the length of the second backboard section 702 most
Small π times for crooked process radius.
It should be noted that the backboard 70 in display device 7 can be above-mentioned any backboard.
Be different from the prior art, backboard is divided into multiple backboard sections by the application, when display device is bent, backboard section due to
It does not stretch mutually each other, it is possible to reduce stretching when display device is bent to backboard becomes to avoid backboard that plasticity occurs
Shape can keep the display effect of display panel so that backboard fold does not occur after display device bending.
It these are only presently filed embodiment, be not intended to limit the scope of the claims of the application, it is every to utilize the application
Equivalent structure or equivalent flow shift made by specification and accompanying drawing content is applied directly or indirectly in other relevant technologies
Field includes similarly in the scope of patent protection of the application.
