Embodiment
The explanation of following embodiment is refer to the attached drawing, can be to the specific embodiment implemented to the example present invention.
It refer to shown in Fig. 1, Fig. 2, the embodiment of the present invention one provides a kind of flexible screen folded state detection means, bag
Include：
Wire 2 is detected, at the predetermined folding for the viewing area 10 for being arranged on the flexible screen 1；
Detection unit 3, detection wire 2 both ends are connected electrically in, for detecting the detection when the flexible screen 1 folds
The resistance of wire 2, and according to the folding angles of the resistance acquisition flexible screen 1 detected；
Control unit 4, electrically connected with the detection unit 3, for the flexible screen 1 provided according to the detection unit 3
Folding angles, control the dispaly state of the flexible screen 1.
The present embodiment is by the predetermined folding for detecting the viewing area 10 that wire 2 is arranged on flexible screen 1（Referring to Fig. 2 institutes
The a-quadrant shown）, when flexible screen 1 folds, detection wire 2 will be because bending will cause resistance to change, the profit of detection unit 3
Judge the folding angles of flexible screen 1 with the resistance size of detection wire 2 detected, and then feed back to control unit 4 and make phase
It should act, flexible screen 1 is responded different folded states.
In the present embodiment, detection wire 2 can be with as shown in figure 3, from the predetermined folding of the side of flexible screen 1 around viewing area
Above or below domain 10 to the opposite side of flexible screen 1 predetermined folding at, formed " ㄇ " or " ㄩ " shape, then respectively with detection
Unit 3 electrically connects；Can also as shown in figure 4, be positioned only at the predetermined folding of the side of flexible screen 1, both ends respectively with detection
Unit 3 electrically connects.As long as that is, resistance variations when can reflect folding, the present embodiment is not intended to limit the tool of detection wire 2
Body set-up mode.
As it was previously stated, when flexible screen 1 folds, according to resistance formula：
Wherein, ρ represents the resistivity of resistance, is determined by itself property, and L represents the length of resistance, and S represents the transversal of resistance
Area.
Detection wire 2 reduces equivalent to L increases, S because bending deforms upon, as a result increases the resistance R of detection wire 2,
Detecting the resistance of wire 2 can increase with the increase of the folding angles of flexible screen 1.
The folding angles α of flexible screen 1 is between the final position after flexible screen folds and the initial position before folding
Angle.As shown in figure 5, the initial position of flexible screen 1 is A1, i.e. horizontal direction；When folded flexible screen in the counterclockwise direction
During curtain 1 to A2, the angle between A2 and A1 is the folding angles α of flexible screen 1.
As described above, pass as shown in Figure 6 be present between the folding angles α of flexible screen 1 and the resistance R for detecting wire 2
System, can form a relation table accordingly, can be by this when the resistance of wire 2 is detected when detection unit 3 detects folding
Resistance inquires about the relation table, obtains folding angles α corresponding to the resistance.Therefore, detection unit 3 further comprises：Detection module,
Resistance for the detection detection wire 2 when flexible screen 1 folds；Enquiry module, for soft according to the resistance inquiry detected
Property screen 1 folding angles with detection wire 2 resistance relation table, obtain folding angles corresponding to the resistance.
After the folding angles for obtaining flexible screen 1, thus control unit 4 can judge the current folded state of flexible screen 1,
And drive control device 5 is controlled according to different folded states（Driver IC）Make flexible screen 1 that different dispaly states be presented,
Such as gradually dark, gradually bright, screen protection, extinguishing.Specifically, folding angles can be set with multiple judgment thresholds, control unit 4 is according to obtaining
The folding angles of the flexible screen obtained control the different dispaly states of flexible screen 1 from the magnitude relationship of each judgment threshold.Example
It is 160 ° such as to set first threshold, if the folding angles α for the flexible screen 1 that detection unit 3 obtains is more than or equal to 160 °, table
The viewing area 10 of bright flexible screen 1 folds will close relatively, and no continuation display content needs, then control unit 4 will pass through
Drive control device 5 controls the viewing area 10 of flexible screen 1 to extinguish and no longer shows or show screen protection.Second Threshold is and for example set
For 30 °, if the folding angles α for the flexible screen 1 that detection unit 3 obtains is more than or equal to 30 °, flexible screen 1 can be controlled
Gradually show slinkingly and show.The concrete numerical value of judgment threshold is set can be according to using being needed freely to set, and the present embodiment is not limited this.
Further, the detection wire 2 of the present embodiment can be single metal wire or multiply metallic cable, in flexible screen
When curtain 1 folds, because bending produces deformation, so that resistance changes.It is irreversible in view of the change in resistance as caused by deformation
And cause conductor wire losses sometimes, therefore detect wire 2 and be also designed to structure as shown in Figure 7.
Shown in reference picture 7, detection wire 2 is flat strip, including connected the first wire 21 and the second wire 22, first
Wire 21 includes the connected first connecting portion 211 of order, the first pars intermedia 212 and respectively from the upper and lower ends of the first pars intermedia 212
A pair of first kinks 213 for extending vertically and being parallel to each other, the second wire 22 include the connected second connecting portion 221 of order,
Second pars intermedia 222 and the second kink 223 from the extension of the central vertical of the second pars intermedia 222, the second kink 223 are embedded into
Abutted against between a pair of first kinks 213 and with the first pars intermedia 212, the first kink 213 then respectively with the second pars intermedia
222 abut against.
When flexible screen 1 folds, detection wire 2 is by the first kink 213 and the second wire 22 of the first wire 21
The second kink 223 residing for region bend, wherein, the second kink 223 is deviate from between the first kink 213（Ginseng
As shown in Figure 8）, form a tensile elongation Δ l（It is shown in Figure 9）, the folding angles α increases of flexible screen 1, stretching can be made
Length Δ l increases therewith, and it can be seen from foregoing resistance formula, the resistance for detecting wire 2 also will increase.Similarly, when detection is single
When member 3 detects the resistance of wire 2 when detecting folding, forgoing relationship table can be inquired about by the resistance, it is corresponding to obtain the resistance
Folding angles α.
Corresponding to the embodiment of the present invention one, the embodiment of the present invention two provides a kind of flexible screen folded state detection method,
Including：
Detection wire is set at the predetermined folding of the viewing area of the flexible screen；
The resistance of the detection wire is detected when the flexible screen folds, and the flexibility is obtained according to the resistance detected
The folding angles of screen；
According to the folding angles of the flexible screen detected, the dispaly state of the flexible screen is controlled.
The operation principle and process of the present embodiment can be found in the explanation of the embodiment of the present invention one, and here is omitted.
By described above, the beneficial effect of the embodiment of the present invention is：Set and examine in flexible screen fold domain
Wire is surveyed, by the detection to detecting conductive line resistance values, obtains the folding angles of flexible screen, and according to different folding angles phases
Dispaly state should be controlled, flexible screen is responded to different folded states, and it is used detection wire into
This is low, easily realizes.
