Foregoing description, here is omitted.
In the embodiment of the present application, the minimum curvature of flexible panel bending when bulge-structure contacts with each other described at least two,
The spacing between shape, height and each bulge-structure to each bulge-structure is related.
For example, Fig. 5 is referred to, when each bulge-structure is rectangle, because the spacing d between each bulge-structure is relative to whole
Individual flexible screen it is small-sized, therefore the radian of bending section is approximately circular arc, therefore deflection angle θ=d/ (π × h) × 180 × 1/
2, it can thus be appreciated that the big of deflection angle θ can be changed by the spacing d between the height h and bulge-structure that change bulge-structure
It is small, you can to determine to be able to detect that by controlling the spacing between the shape of each bulge-structure, height and each bulge-structure
Flexible panel bending minimum curvature.When the minimum curvature of the flexible panel bending being able to detect that is got over hour, easier inspection
Measure flexible panel and there occurs bending.
Fig. 6 is referred to, when base when each bulge-structure is trapezoidal and trapezoidal is located at the outside of conductive material, deflection
Angle, θ=180- (90-d/ (π × h) × 180 × 1/2)-β, it can thus be appreciated that by changing the height h of bulge-structure and each convex
Play the angle beta of the spacing d or trapezium base between structure, thus it is possible to vary the size of θ, you can with by controlling each bulge-structure
Spacing between shape, height and each bulge-structure determines the minimum curvature of flexible panel bending being able to detect that.Work as energy
The minimum curvature of the flexible panel bending for enough detecting is got over hour, is more readily detected flexible panel and there occurs bending, that is, detect
The sensitivity of bending direction is higher.
The shape of the bulge-structure in the embodiment of the present application can be any shape, in order to improve the spirit of detection bending direction
Sensitivity, it is preferred that the cross sectional shape of bulge-structure is trapezoidal, and the trapezoidal bottom is positioned at the outside of conductive layer.
It should be noted that the embodiment of the present application is not specifically limited to the quantity of bulge-structure, same the application is implemented
Example shape not to each bulge-structure, the spacing between height and each bulge-structure are specifically limited, and it can be according to curved to detecting
The sensitivity of Qu Fangxiang and specifically set.
In the embodiment of the present application, contact area when being contacted with each other between each bulge-structure bends with the flexible panel
Curvature it is related.Because each bulge-structure can often produce certain deformation in stress, when the degree of flexible panel bending is got over
When big, i.e., when bending curvature is bigger, the power of the mutual extruding being subject between each bulge-structure can be bigger, so, each bulge-structure
Between can produce certain deformation, then the contact area between each bulge-structure can be bigger.Contact between each bulge-structure
When area is bigger, the cross-sectional area that electric current passes through will be bigger, and electric current will be bigger.That is, when panel bending degree causes more greatly
When contact area when being contacted with each other between bulge-structure is bigger, will be more by the electric current of the first conductive layer or the second conductive layer
Greatly.
Therefore, in the embodiment of the present application, the electric current that the first conductive layer and/or the second conductive layer can be passed through by detection
It is worth to determine the bending curvature of flexible panel, the specific method for determining bending curvature please be referred to hereinafter to bending direction identification side

Wherein, the flexible display apparatus for example can be flexible organic electroluminescent device, but not limited to this；As long as energy
Enough flexible display apparatus bent to both sides, within the protection domain of the application.
Based on flexible screen and/or display device that the application is provided, the application also provides a kind of bending direction recognition methods,
The executive agent of the bending direction recognition methods that the embodiment of the present application is provided can be flexible screen or display device, etc..
For ease of description, as a example by hereafter executive agent in this way is detecting system, the implementation method to the method is entered
Row is introduced.It is appreciated that the executive agent of the method is a kind of exemplary explanation for flexible screen, it is not construed as to this
The restriction of method.Here flexible screen can be the previously described flexible screen based on the application design, and the flexible screen possesses inspection
Examining system, detecting system is electrically connected with the first conductive layer, and the bending of flexible screen can be detected by detecting system, therefore,
The executive agent of the method can also be detecting system.
The method realizes schematic flow sheet as shown in fig. 7, comprises following step：
Step S501：Apply constant voltage to the first conductive layer two ends；
Constant voltage mentioned here can be the voltage that magnitude of voltage fluctuates in certain error allowed band, should not be understood
For the value of voltage is uniquely constant, it will be apparent to those skilled in the art that in actual applications, keeping magnitude of voltage bending constant, it is
Extremely difficult.
According to electric current=voltage/resistance, it is known that, under conditions of voltage is nearly constant, by the electric current of the first conductive layer
Resistance with the first conductive layer is inversely proportional, then, when flexible panel bends to predetermined direction, on the first conductive layer at least two
Bulge-structure contacts with each other, and can cause that the first resistance conductive layer diminishes.
Step S502：It is determined that by the electric current of first conductive layer；
The specific method for determining the first conductive layer electric current, such as can be to be in by detection and the first conductive layer same
The electric current of any point determines in circuit, and the embodiment of the present application is repeated no more to this.
Step S503：When it is determined that the electric current be more than default first threshold when, it is determined that the flexible panel it is curved
Qu Fangxiang is predetermined direction.
When flexible panel bends to predetermined direction, at least two bulge-structures on the first conductive layer contact with each other, and can make
Obtain the first resistance conductive layer to diminish, and then cause the electric current of the first conductive layer to become big.So, when detecting by the first conductive layer
Electric current become big or during more than default first threshold, the bending direction that just can determine flexible panel is predetermined direction.
The occurrence of first threshold can determine according to actual service conditions, as long as big in the electric current by the first conductive layer
When the first threshold, it is able to detect that flexible panel there occurs bending to predetermined direction.
Based on description above to flexible screen, when flexible panel bends to direction opposite to the predetermined direction, due to right
First conductive layer along the sense of current stretching, the resistance value along the sense of current of the first conductive layer can become big, then, by first
The electric current of conductive layer can reduce, therefore, in the embodiment of the present application, can also be diminished by the electric current of the first conductive layer detecting
Or during less than default Second Threshold, just can determine that flexible panel there occurs to direction opposite to the predetermined direction curved
It is bent.
Equally, Second Threshold refer specifically to can be determined according to actual service conditions, as long as by the first conductive layer
When electric current is less than the Second Threshold, it is able to detect that flexible panel there occurs bending to direction opposite to the predetermined direction.
In the embodiment of the present application, the bending curvature of flexible panel can also be determined according to the value of the electric current for determining.
Specifically, firstly, since flexible panel bending when bulge-structure contacts with each other described at least two of flexible screen
Minimum curvature, the spacing between shape, height and each bulge-structure to each bulge-structure is related, therefore, it can by setting
The shape of each bulge-structure, the spacing between height and each bulge-structure set the flexible panel being able to detect that bending
Minimum curvature.
Secondly, contact area when being contacted with each other between each bulge-structure, it is related to the curvature that the flexible panel bends,
Therefore it is conductive by first when the contact area when contacting with each other between panel bending degree causes bulge-structure more greatly is bigger
The electric current of layer or the second conductive layer will be bigger.So, the corresponding relation between current value and bending curvature can be pre-build,
The corresponding relation can be measured by experiment, such as when a certain curvature has been bent, the first conductive layer or the when testing the curvature
The size of the electric current of two conductive layers, that is, establish the corresponding relation of the curvature and electric current.
When subsequently being bent to flexible screen, just can be according to the curvature and the corresponding relation of electric current set up, it is determined that electric current
Value after, you can it is determined that curvature corresponding with the value of the electric current.
