Device 40a includes the edge protrusion 46a in the first electromagnetic actuators 40b and the second electromagnetic actuators 40c, the first electromagnetic actuators 40b
It is d1 perpendicular to the length on the direction of flexible display panels, protrusion 46b is along perpendicular to flexibility in the second electromagnetic actuators 40c
Length on the direction of display panel is d2；Wherein,
D1 > d2 > 0.
Specifically, continuing to refer to figure 13, electromagnetic actuators 40a includes the first electromagnetic actuators 40b and second Electromagnetically actuated
Device 40c, wherein the edge protrusion 46a is greater than perpendicular to the length on the direction of flexible display panels in the first electromagnetic actuators 40b
The edge protrusion 46b is perpendicular to the length on the direction of flexible display panels in second electromagnetic actuators 40c, in the first state,
First electromagnetic actuators 40b can make the Deformation Height of the corresponding part of flexible display screen 10 be greater than the second electricity by protrusion 46a
Magnetic actuator 40c makes the Deformation Height of the corresponding part of flexible display screen 10 by protrusion 46b, and Deformation Height refers to flexible aobvious
The part to deform in display screen 10 and the part not deformed most greatly enhancing on the direction perpendicular to flexible display panels
Degree.
In the first state, by the first electromagnetic actuators 40b and the second electromagnetic actuators 40c, user is touching flexibility
Different touch feedbacks is obtained when display screen.Illustratively, the electromagnetic actuators 40a in the embodiment of the present invention can be matched with flexibility
In dummy keyboard in display panel, the first electromagnetic actuators 40b is for the F key and J key in matching virtual keyboard, the second electromagnetism
Actuator 40c is for other keys in matching virtual keyboard in addition to F key and J key, further such that user is using virtual key
It is obtained when disk and the feeling close using physical keyboard, promotes the usage experience of user.It is understood that the embodiment of the present invention
Merely exemplary illustrates that electromagnetic actuators can be matched in the dummy keyboard in flexible display panels, and electromagnetic actuators can also be used
In display panel in other keys or other need to provide the part of touch feedback, and electromagnetic actuators can also include and the
One electromagnetic actuators and different other electromagnetic actuators of the second electromagnetic actuators structure, the first electromagnetic actuators and the second electromagnetism
Other arrangement modes can also be taken between actuator, the embodiment of the present invention is not particularly limited.
Further, for matching, shared region area in flexible display panels is biggish virtually to be pressed the first electromagnetic actuators
Key, the second electromagnetic actuators are for matching the shared lesser virtual key of region area in flexible display panels.Since flexibility is aobvious
The Deformation Height of the part to deform in display screen is bigger, and the area to deform at this in corresponding flexible display screen is bigger,
So that the deformation of the first electromagnetic actuators is so that the area in the region that deformation occurs in flexible display screen is larger, to match flexibility
The shared biggish virtual key of region area, further increases the usage experience of user, family can be used and pass through in display panel
It touches and may recognize that different function key.
Figure 14 is the structural schematic diagram of another flexible display panels provided in an embodiment of the present invention, with reference to Figure 11 and figure
14, optionally, wherein in the first state, coil 42 generates piston 41 to be made along perpendicular to first on the direction of supporting layer
Firmly F1, for spring 31 to electromagnetic actuators 40a there are elastic force F2, the first directed force F 1 is identical with the direction of elastic force F2, and first
Directed force F 1 is greater than elastic force F2.
Specifically, since the first directed force F 1 is far longer than elastic force F2, so that user becomes in pressing flexible display screen 10
When the position of shape, pressing can first cause spring 31 to be compressed, and the positional relationship of 40 coil 42 of actuator and piston 41 is also kept
It is constant.
Specifically, the positional relationship of 40 coil 42 of actuator and piston 41 also remains unchanged, pass through the compression of spring 31
So that the position deformed in flexible display screen 10 is restored back to flat condition, the position deformed in pressing flexible display screen 10 is effectively relieved
When flexible display screen 10 in the position that deforms be restored back to existing delay issue when flat condition.And it effectively solves for more
Secondary, high-frequency click touch control operation, actuator 40 have little time the case where changing deformed state, further increase the use of user
Experience.Avoiding brake to deform back and forth simultaneously reduces the service life, can also reduce power consumption.
It should be noted that in other embodiments of the present invention in order to obtain the position for needing to deform in flexible display screen 10
More large deformation is obtained, can be superimposed using multiple actuator layers, and different types of actuator, illustratively, first can be used
Actuator and the second actuator are arranged along the direction perpendicular to flexible display panels, and the second actuator is located at the first actuating
Between device and flexible display screen, wherein the deformation of the first actuator causes the second actuator in the side perpendicular to flexible display panels
Move upwards, the deformation of the second actuator makes flexible display screen local deformation, at this time in flexible display screen corresponding site deformation
For the effect of the deformation superposition of the deformation and the second actuator of the first actuator, the effect of flexible display screen deformation can be further promoted
Fruit, the present invention no longer repeat this one by one.
The embodiment of the present invention provides a kind of flexible display apparatus, including flexible display panels as described above 100.
