The hardened layer 220 can be to increase the intensity for being located at the flexible screen body 100 of the bent area 120.?
In one embodiment, the material of the hardened layer 220 includes alchlor, ceramics or organic gel.The hardened layer 220 can also
Think the organic gel coated on 210 surface of branch fastener, is formed by hardening process.The hardening process can be hard for high temperature
Chemical industry skill or ion-exchange process.It is appreciated that the flexible screen body 100 positioned at the bent area 120 becomes due to being bent
Shape can generate deformational stress.Extrusion stress can be generated in the first surface 121, stretching can be generated in the second surface 123
Stress.Therefore the distance between molecule of material of the second surface 123 is larger, is easily damaged.The hardened layer 220 is set
The branch fastener 210 is placed in close to the surface of the bent area 120, the bent area 120 can be effective against by from outer
The pressure on boundary, and by pressure dissipation, it is possible to reduce it is subject to positioned at the part of the flexible screen body 100 of the bent area 120
Pressure.Therefore the hardened layer 220 can effectively prevent the bent area 120 since bending stress or foreign impacts power cause
Damage.
In the display panel 10 provided by the present application, the support portion 200 includes the branch fastener 210 and the support
Main body 240.The hardened layer 220 is set to the surface of the branch fastener 210, and passes through the adhesive layer 230 and described first
Surface 121 fits together.The hardened layer 220 fits together with the first surface 121 can be to positioned at the bending
The flexible screen body 100 in area 120 does effective support, avoids the flexible screen body 100 positioned at the bent area 120 due to bending stress
Or it is damaged by external impacts, and can effectively ensure that the bending state of the bent area 120 is stablized.
In one embodiment, the surface close to the adhesive layer 230 of the hardened layer 220 is arranged at intervals with multiple recessed
Slot 122.The adhesive layer 230 fills the multiple groove 122.The surface of first groove 122 can cover the bonding
Layer 230.First groove 122 can make the first surface 121 coarse, therefore enhance the adhesive layer 230 and described the
The frictional force on one surface 121, enhances the intensity of bonding.The cross section of first groove 122 can be round or irregular
Polygon.Since the first surface 121 has the distortional stress being pressurized, density increases between material molecule, by setting
The rock deformation pressure of the first surface 121 can be discharged by setting the groove 122, avoid being located at the bent area 120 due to deformation
The accumulation of stress and damage.
In one embodiment, the cross section of the groove 122 is circle.From the centre of the first surface 121 to institute
The two sides of first surface 121 are stated, the diameter of the groove 122 becomes larger.It is appreciated that cross-sectional area is circular described recessed
122 manufacture craft of slot is easy to accomplish.The curved shape of the bent area 120 can be arc.Therefore the bending in arc top region becomes
Shape is maximum, also maximum in the deformational stress of the first surface 121 accumulation.Therefore at the arc top, that is, the bent area
120 middle section by setting there is larger-diameter groove 122 can be released effectively deformational stress.From first table
The centre in face 121 to the two sides of the first surface 121, the deformational stress of the first surface 121 are gradually reduced.Therefore corresponding
The diameter of the groove 122 can also be gradually reduced, therefore the stress release of the first surface 121 can be made more
Uniformly.
Fig. 3 is referred to, in one embodiment, the inner wall setting jagged 124 of the groove 122.The adhesive layer 230
It is bonded by the burr with 122 inner wall of groove.The burr 124 can be individual structure, be set to it is described state it is recessed
The inner surface of slot 122.The burr 124 can also be formed during the groove 122 formation by drawing process.When
When the adhesive layer 230 is coated on the inner surface of the groove 122, the burr 124 can increase the groove 122 and described
Cohesive force between adhesive layer 230.The burr 124 can be by the fastness between the groove 122 and the adhesive layer 230
Improve nearly 30%.
In one embodiment, the thickness of the hardened layer 220 is from the middle part of the bent area 120 to the bent area
120 two sides are gradually thinning.The curved surfaces can be corresponding with the bending shape of the bent area 120, therefore the arc
Shape surface can agree with 121 phase of first surface.It is appreciated that the song of the curved surfaces and the first surface 121
Rate radius can be identical, thus can guarantee optimal fit-state.When the bent area 120 is arc, arc top deformation
Maximum, distortional stress is maximum, therefore impact resistance is worst.And the bent area 120 is located at the side of the flexible screen body 100
Edge, it is easier to be damaged because of colliding with.Therefore make the hardened layer 220 positioned at the middle part of the bent area 120 most thick, it can be into one
Step enhances the resistance to deformation and impact resistance on the arc top of the bent area 120.

The radius of curvature of the curved surfaces of first 210 two sides.The first surface 121 of the bent area 120 will fit in described
Branch fastener 210.Therefore the shape of the branch fastener 210 can determine the curved shape of the bent area 120.When the branch fastener
The radius of curvature of the curved surfaces among 210 is less than the radius of curvature of the curved surfaces of 210 two sides of branch fastener
When, the song of the bending radius of the middle section of the bent area 120 again smaller than the curved surfaces of 120 two sides of bent area
Rate radius.The smaller deformation that can make 120 middle section of bent area of the bending radius of 120 middle section of bent area
Than more gentle, therefore deformation sharply is avoided to destroy the flexible screen body 100.It is rushed simultaneously in the bent area 120 by external force
Effectively impact force can be transmitted around when hitting, further enhance the stability of the bent area 120.
In one embodiment, the curved surfaces are matte surface.The matte surface can increase the hardened layer
Frictional force between 220 and the branch fastener 210, thus can falling off to avoid the hardened layer 220.
