In order to which Flexible Displays backboard 100 is enable easily to be bent and is converted between bending and extended position, in flexibility
Touch switch 130 is provided on display backboard 100.Touch switch 130 can be connected with ER fluid 124, to become to electric current
Liquid 124 is powered, so whether be powered using ER fluid 124 in the case of solid, liquid conversion characteristic reach bending or unfold
Purpose.
It please refers to Fig.1 to Fig. 3, Flexible Displays backboard 100 is connected in sequence by multiple support elements 110, is formed with carrying
The loading end 112 of flexible display 200 and positioned at the first side 114 of 112 both sides of loading end and second side 116, in addition also
It is formed with two free ends.After flexible display 200 is placed on Flexible Displays backboard 100, flexible display 200 can be with
Flexible Displays backboard 100 is bent and is wound into together shaft-like.After Spindle Status is wound into, Flexible Displays backboard 100
A meeting in two free ends is rolled, and two sides are then constantly exposed to outside.It therefore, will in the present embodiment
Touch switch 130 is arranged on the side of Flexible Displays backboard 100, and touch switch 130 is made to be constantly exposed to outside, is convenient for
Operation.
It please refers to Fig.3, the both ends of flexible piece 120 are respectively equipped with the first electrode for being provided with and being inserted into storage space 122
140 and second electrode 150, first electrode 140 be located at first side 114, second electrode 150 is located at second side 116.It is soft
The both ends of property part 120 are also respectively provided with the first conducting wire 160 and the second conducting wire 170.First conducting wire 160 and the second conducting wire 170 divide
It is not set in first side 114 and second side 116, is respectively intended to be connected with the positive and negative electrode of power supply.Touch switch 130
It is arranged at first side 114 and is connect with the first conducting wire 160, the second conducting wire 170 is then connect with second electrode 150.In this way, it touches
Control switch 130, first electrode 140 and second electrode 150 are set up one between the first conducting wire 160 and the second conducting wire 170 and are returned
Road can realize the conducting in the circuit by operating touch switch 130.
Since Flexible Displays backboard 100 is connected in sequence by multiple support elements 110, in Flexible Displays backboard 100
First side 114 on be provided with multiple touch switches 130, quantity and aforementioned connecting joint（That is flexible piece 120）Number
Amount is consistent.That is, being respectively provided between two adjacent support elements 110, there are one touch switches 130.In the present invention, first
All touch switches 130 are together in parallel by conducting wire 160, and multiple second electrodes 150 are then together in parallel by the second conducting wire 170, change
Yan Zhi is parallel with multiple circuits between the first conducting wire 160 and the second conducting wire 170, makes the ER fluid of Flexible Displays backboard 100
124 supply line is more succinct.
Flexible display apparatus is summarized as follows by the operating process of extended position to flexuosity：When needing to fill Flexible Displays
Some location bending for putting and when keeping flexuosity, ensure first touch switch 130 at the position not with corresponding flexibility
First electrode 140 in part 120 contacts, and ER fluid 124 is not powered on being liquid at this time, then makes flexible display apparatus at this
It is bent at position.After flexible display apparatus bending, the touch switch 130 of the position is pressed, makes the touch switch being pressed 130
It is contacted with corresponding first electrode 140, ER fluid 124 is energized, and is converted to solid-state by liquid, is kept flexible display apparatus
In the state of bending.Flexible display apparatus is by the operating process of flexuosity to extended position with aforementioned process on the contrary, no longer superfluous
It states.
It please refers to Fig.4, the schematic diagram of the flexible display apparatus single-point bending for the present invention.In Fig. 4, flexible display 200
Form a horizontal component and a sloping portion after bending, wherein horizontal component is input mechanism, sloping portion to show image,
The flexible display apparatus of the present invention is allow to be used as desktop computer.At this point, the ER fluid 124 in knee is electrification
, it is solid-like, therefore flexible display apparatus can keep flexuosity shown in Fig. 4.It needs to make flexible display apparatus extensive
It is multiple to the formation state unfolded when, first unclamping touch switch 130 makes ER fluid 124 is not charged to restore to liquid condition, then
Flexible display apparatus is made to restore to the formation state unfolded, at this point, flexible display apparatus can be used as tablet computer.
Please refer to Fig. 5, the schematic diagram of flexible display apparatus multi-point bending.First, flexible display apparatus is first formed by bending one
Then horizontal component and a sloping portion, are bent in being generated again on sloping portion at two.In this way, flexible display apparatus can be hung
With, wearable state is presented.
Fig. 6 is please referred to, flexible display apparatus is bent at each connecting joint, and forms a ring-type, equally may be used at this time
It realizes wearable state, can such as be worn in wrist, can also act as the function of wrist-watch.In order to make the head and the tail of flexible display apparatus
It can link together, be additionally provided with attachment device 180.Attachment device 180 can be male and female fit structure or magnet mechanism or
Other fixed structures.
In other implementations, touch switch 130 is not necessarily arranged on the first of Flexible Displays backboard 100
On side 114, for example, it is also possible to be connect using lead with first electrode 140, in the touch-control that other positions setting is connected with lead
Switch 130 is also feasible.Equally, the first conducting wire 160 and the second conducting wire 170 also may be not necessarily provided at Flexible Displays backboard
It, can also be in other suitable positions for being arranged on flexible display apparatus, e.g., on other attachmentes, as long as can become to electric current on 100
Liquid is powered.
In above-mentioned flexible display apparatus, Flexible Displays backboard 100 include multiple support elements 110, adjacent support element 110 it
Between connected by flexible material, therefore can be bent.ER fluid 124 is accommodated between adjacent support element 110, by giving electricity
The energization of rheology liquid 124 makes it be converted to solid state, and Flexible Displays backboard 100 can be made to be maintained at flexuosity.Therefore, it is flexible aobvious
Show that backboard 100 can adapt to requirement of the bending of flexible display 200 with unfolding conversion, and the degree of bending can control.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
