The flexible display device 100 in this application refers to an electronic device comprising a flexible display screen 10.

On the other hand, when the user does not need to use the flexible display device 100, the user can also reduce the occupied space by folding the flexible display device, thereby improving the portability of the flexible display device.

The flexible display screen 10 includes, but is not limited to, Quantum Dot Light Emitting Diodes (QLEDs), Organic Light-Emitting Diode (OLED) flexible display screens, and the like, and is not limited herein.

The flexible display device 100 may be, but not limited to, a mobile phone, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, an intelligent bracelet, a pedometer, etc., and is not limited herein. The flexible display device 100 includes, but is not limited to, a flexible display screen 10, a memory 20, a processor 30, a plurality of sensors 40, and at least one signal emitter 50. In particular, the flexible display screen 10, the memory 20, the processor 30, the plurality of sensors 40, and the at least one signal emitter 50 may be coupled by a communication bus 60. The processor 30 is electrically connected to the plurality of sensors 40 and the at least one signal emitter 50, respectively. It should be understood by those skilled in the art that fig. 1 is only an example of the flexible display apparatus 100 and does not constitute a limitation to the flexible display apparatus 100, and the flexible display apparatus 100 may include more or less components than those shown in fig. 1, or combine some components, or different components, for example, the flexible display apparatus 100 may further include an input and output device, a network access device, and the like.

The memory 20 may be used for storing computer programs and/or modules, and the processor 30 implements various functions of the flexible display device 100 by running or executing the computer programs and/or modules stored in the memory 20 and calling data stored in the memory 20. The memory 20 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, application programs (such as a sound playing function, an image playing function, etc.) required for a plurality of functions, and the like; the data storage area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like.

In addition, the memory 20 may include a high speed random access memory, and may also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), a plurality of magnetic disk storage devices, a Flash memory device, or other volatile solid state storage devices.

The Processor 30 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic device, discrete hardware component, etc. The general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, the processor is the control center of the flexible display device 100, and various interfaces and lines are used to connect the various parts of the entire flexible display device 100.

Specifically, the at least one signal emitter 50 is configured to generate an emission signal, and the plurality of sensors 40 are configured to receive the emission signal and generate corresponding sensing data according to the strength of the received emission signal. The processor 30 is electrically connected to the plurality of sensors 40, and is configured to acquire sensing data of the plurality of sensors 40, determine whether there is a change in the sensing data generated by the sensors 40 according to the received sensing data, and determine that at least two sensors 40 with changed sensing data are target sensors 40 when there is a change in the sensing data. The processor 30 also determines a bending line of the flexible display device 100 according to the determined coordinates of the target sensor 40, thereby determining a bending position of the flexible display device 100.

Wherein the magnitude of the sensed data generated by the plurality of sensors 40 is proportional to the strength of the received transmission signal. For example, when the sensor 40 does not receive a transmission signal, no sensing data is generated; when the sensor 40 receives a weak sensing signal, the generated sensing data is small; when the sensor receives a stronger transmitted signal, greater sensed data is generated.

In this embodiment, when the flexible display device 100 is not bent, the plurality of sensors 10 do not receive the emission signal generated by the signal emitter 50, and thus do not generate sensing data; when the flexible display device 100 is bent, the sensor 10 located in the bent region can receive the emission signal generated by the signal emitter 50 to generate sensing data. In other embodiments, the plurality of sensors 10 may receive the emission signal generated by the signal emitter 50 when the flexible display device 100 is not bent, and may not receive the emission signal generated by the signal emitter 70 when the flexible display device 100 is bent.

The flexible display device 100 disclosed in the embodiment of the present application includes at least one signal emitter 50 and a plurality of sensors 40, and the plurality of sensors 40 can generate corresponding sensing data according to the intensity of the received emission signal, so that when the flexible display device 100 is bent, the sensing data of the sensor 10 located at the bent position can be changed, and therefore, the processor 30 can determine the bending line of the flexible display device 100 by obtaining the sensing data of the plurality of sensors 10 and according to the coordinates of the target sensor 10 where the sensing data is changed, so as to determine the bending position of the flexible display device 100. In this way, the flexible display device 100 can be controlled according to the bending position, for example, different interaction functions can be realized by controlling the flexible display device 100 according to different bending positions, and then the experience of the user on the flexible display device 100 is improved.

Referring to fig. 2, the flexible display device 100 further includes a housing 70 disposed opposite to the flexible display screen 10. The plurality of sensors 40 may be disposed on the flexible display screen 10 and/or the housing 70. In particular, the sensor 40 may be arranged at an inner surface of the flexible display screen 10 facing the housing 70 or/and on an outer surface facing away from the housing 70. Similarly, the sensor 40 may also be disposed at an inner surface of the housing 70 facing the flexible display screen 10 or/and on an outer surface facing away from the flexible display screen 10.

In some embodiments, the flexible display device 100 further includes a flexible circuit board (not shown) disposed between the flexible display screen 50 and the housing 60, and the plurality of sensors 10 are disposed on the flexible circuit board and attached to the flexible display screen 50 or the inner surface of the housing 60.

In this embodiment, the plurality of sensors 40 may be embedded in the flexible display 10, or may be attached to an outer edge of the surface of the flexible display 10. Wherein, the plurality of sensors 40 are disposed at the outer edge of the flexible display screen 10 to form a shape matching the shape of the flexible display screen 10. For example, when the flexible display screen 10 is rectangular, the plurality of sensors 40 also fit to the outer edge of the flexible display screen 10 in a rectangular shape; when the flexible display screen 10 is circular, the plurality of sensors 40 are also circularly fitted to the outer edge of the flexible display screen 10; when the flexible display screen 10 is polygonal, the plurality of sensors 40 are also in a polygonal shape corresponding to the flexible display screen 10 and are attached to the outer edge of the flexible display screen 10, which is not limited herein.

Specifically, a two-dimensional rectangular coordinate system may be established with the surface of the flexible display screen 10 that is not bent as a coordinate plane, and a certain point on the flexible display screen 10 as an origin of coordinate, and after the origin of coordinate is determined, the coordinate of each sensor 10 relative to the origin of coordinate is also determined accordingly, so that the bent line can be determined according to the coordinate as long as the target sensor 10 with changed sensing data is found out.

In some embodiments, the number of the signal emitters 50 is the same as the number of the outer edges of the flexible display screen 10, one signal emitter 50 is disposed on each side of the flexible display screen 10, the plurality of sensors 40 are disposed on the outer edges of the flexible display screen 10, each signal emitter 50 generates an emission signal in a single direction, and the propagation direction of the emission signal generated by each signal emitter 50 is parallel to the outer edge thereof. When the flexible display screen 10 is not bent, the propagation direction of the emission signal does not intersect with the sensor 40 disposed on the outer edge where the signal emitter 50 is located; when the flexible display screen 10 is bent, the propagation direction of the emission signal intersects a sensor 40 disposed on the outer edge where the signal emitter 50 is located.

Referring to fig. 3 again, in the present embodiment, the flexible display screen 10 includes a pair of parallel first sides 11 and a pair of parallel second sides 12 perpendicular to the first sides, and the pair of first sides 11 and the pair of second sides 12 form a rectangle. The plurality of sensors 10 are respectively disposed in the flexible display screen 10 along a pair of first sides 51 and a pair of second sides 52. The number of the signal emitters 50 is 4, and each signal emitter 50 is disposed at a corner of the flexible display screen 10, where the corner is where the first side 11 and the second side 12 intersect. In the present embodiment, the signal emitter 50 is a light emitter which generates a light ray in a single direction, and the light ray is parallel to the distribution direction of the corresponding plurality of sensors 40 and does not intersect with the plurality of sensors 40. For example, the light emitted by the first signal emitter 50 is parallel to the first side edge 11, and the light emitted by the second signal emitter 50 is parallel to the second side edge 12, so that the propagation direction of the emitted signal generated by each signal emitter 50 forms a shape consistent with the flexible display screen 10.

In the present embodiment, the sensor 10 is a photosensitive sensor. When the light sensor receives the light emitted from the signal emitter 50, the light sensor generates sensing data in the form of voltage or current. The processor 30 acquires sensing data in the form of voltage or current of the plurality of photosensitive sensors and determines the photosensitive sensor generating the sensing data as a target sensor of which sensing data is changed.

For example, when the light sensor does not receive light, it has no voltage output, i.e. the output voltage is 0; when the photosensitive sensor receives light, a voltage is output, and the output voltage is different along with the intensity of the received light. Specifically, when the light received by the photosensor is strong, the generated voltage value is also large, and conversely, when the light received by the photosensor is weak, the generated voltage value is also small. Therefore, when the processor 30 receives a voltage output from one of the photosensors, it can determine the photosensor generating the sensing data as the target sensor and obtain the coordinates of the target sensor, and when two photosensors generate the sensing data, it can determine a straight line, which is the bending line of the flexible display device 100, according to the coordinates of the two photosensors. In addition, since the plurality of photosensors are arranged in a rectangular shape corresponding to the flexible display screen 10, no matter where the flexible display device 100 is bent, at least two photosensors receive the light emitted from the signal emitter 50 to change the sensing data, so as to determine the bending line of the flexible display device 100.

Referring to fig. 4, when the flexible display panel 10 is not bent, the light emitted from the signal emitter 50 propagates in a direction parallel to the plane of the flexible display panel 10 (see the direction of the arrow in fig. 4). Therefore, when the flexible display device 100 is not bent, the plurality of photosensitive sensors theoretically do not receive light, but actually receive light slightly due to refraction caused by the medium in the air, but a voltage signal generated by the weak light is weak and can be ignored.

Referring to fig. 5, when the flexible display device 100 is bent, light emitted from the signal emitter 50 enters the photosensitive sensor located at the bent position, and the photosensitive sensor receives the light emitted from the signal emitter 50 to generate a voltage signal and sends the generated voltage signal to the processor 30. For example, referring to fig. 3, when the flexible display device 100 is bent along the bending line L, one of the photosensors disposed along one of the first side edges 11 and one of the photosensors disposed along the other first side edge 11 receive the light emitted from the signal emitter 50, so as to generate the voltage signal. The processor 30 can determine the coordinates of one of the photosensors as (x1, y1) and the coordinates of the other photosensor as (x2, y2) based on the received voltage signals, so that the position of the bend line L can be derived. It is understood that the distance between the plane formed by the light emitted from the signal emitter 50 and the plane formed by the plurality of sensors 10 can be set according to specific design requirements, and is not limited herein.

In one embodiment, the signal emitter 50 is configured to emit invisible light so as not to affect the visual experience of the user. Wherein the invisible light includes ultraviolet rays, infrared rays, far infrared rays, and the like. Preferably, the light emitted from the signal emitter 50 is infrared rays with strong penetrating power, and the photosensitive sensor for receiving the infrared rays has an advantage of high sensitivity.

In other embodiments, the signal emitter 50 emits light in multiple directions, which form coverage areas in the same plane, and the plane formed by the multiple directions of light is parallel to the plane of the flexible screen 10 in the initial state (where no bending occurs) and parallel to the plane of the sensor 40. The coverage area covers the area of the flexible display screen 10 where the sensor 10 is arranged, so that any photosensitive sensor can receive light rays emitted by the signal emitter 50 as long as the position of the photosensitive sensor changes, and the accuracy of determining the position of the bend line can be improved.

Referring to fig. 6, in this embodiment, the flexible display device 100 further includes a flexible substrate 80, the flexible substrate 80 is attached to one side of the flexible display screen 10, and the plurality of photosensitive sensor arrays are distributed on the flexible substrate 80 in a dot matrix and are closely attached to the flexible display screen 10, that is, a coordinate map of a sensing point is formed by the photosensitive sensors at each point. Therefore, after receiving the sensing data transmitted by the photosensor array, the processor 30 can select the photosensors generating the sensing data, and determine the coordinates thereof to determine the bending line of the flexible display device 100, thereby improving the accuracy of determining the bending position.

In this embodiment, the shape of the flexible substrate 80 is identical to the shape of the flexible display panel 10. When there is only one signal emitter 50, the location of the bend can be determined. It should be noted that when the flexible display screen 10 is bent, the plurality of sensors 40 at the bending position receive the transmission signal, that is, the sensing data of the plurality of sensors 40 will change, so that the bending line determined by the coordinates of the plurality of sensors 40 is a curve, while the bending line determined by the coordinates of the two sensors 40 in the foregoing embodiment is a straight line.

Please refer to fig. 7, which is a flowchart illustrating a bending position determining method according to the present disclosure. The bending position determining method is applied to a flexible display device 100, and the flexible display device 100 comprises at least one signal emitter 50 and a plurality of sensors 40. Wherein, each sensor corresponds to a coordinate position. The bending position determining method comprises the following steps:

step S71, acquiring the sensing data generated by the plurality of sensors, and determining the coordinates of the target sensor with the changed sensing data according to the acquired sensing data.

And step S72, determining the bending position of the flexible display device according to the coordinates of the target sensor.

In the bending position determining method disclosed in the embodiment of the present application, since the flexible display device 100 includes at least one signal emitter 50 and a plurality of sensors 40, and the plurality of sensors 40 can generate corresponding sensing data according to the strength of the received emission signal, so that when the flexible display device 100 is bent, the sensing data of the sensor 10 located at the bending line can be changed, and therefore, the processor 30 can determine the bending line of the flexible display device 100 by obtaining the sensing data of the plurality of sensors 10 and according to the coordinates of the target sensor 10 whose sensing data is changed, so as to determine the bending position of the flexible display device 100. In this way, the flexible display device 100 can be controlled according to the bending position, for example, different interaction functions can be realized by controlling the flexible display device 100 according to different bending positions, and then the experience of the user on the flexible display device 100 is improved.

Please refer to fig. 8, which illustrates a sub-flowchart of step S71 in an embodiment of the present application. In this embodiment, step S71 specifically includes the following steps:

in step S711, sensing data of the plurality of sensors is acquired.

Step S712, determining whether the acquired sensing data is changed; if yes, go to step S713; if not, the process ends.

In this embodiment, when the flexible display device 100 is not bent, the plurality of sensors 10 do not receive the transmission signal generated by the signal transmitter 50 and do not generate sensing data; when the flexible display device 100 is bent, the sensor 10 located in the bent region receives the emission signal generated by the signal emitter 50 to generate sensing data. In other embodiments, the plurality of sensors 10 may receive the emission signal generated by the signal emitter 50 when the flexible display device 100 is not bent, and may not receive the emission signal generated by the signal emitter 50 when the flexible display device 100 is bent.

Step S713, determining the sensor with the changed sensing data as a target sensor, and determining coordinates of the target sensor.

In this embodiment, the flexible display device 100 further includes a flexible display screen 10, and specifically, a two-dimensional rectangular coordinate system may be established with a surface of the flexible display screen 10 when the flexible display screen 10 is not bent as a coordinate plane, and a certain point on the flexible display screen 10 as an origin of coordinate, after the origin of coordinate is determined, a coordinate of each sensor 10 relative to the origin of coordinate is also determined accordingly, so that a bending line of the bent portion can be determined according to the coordinate as long as a target sensor 10 whose sensing data changes is found out.

In some embodiments, the plurality of sensors 40 may be built into the flexible display screen 10 or may be attached to the outer edge of the surface of the flexible display screen 10. Wherein, the plurality of sensors 40 are disposed at the outer edge of the flexible display screen 10 to form a shape matching the shape of the flexible display screen 10. For example, when the flexible display screen 10 is rectangular, the plurality of sensors 40 also fit to the outer edge of the flexible display screen 10 in a rectangular shape; when the flexible display screen 10 is circular, the plurality of sensors 40 are also circularly fitted to the outer edge of the flexible display screen 10; when the flexible display screen 10 is polygonal, the plurality of sensors 40 are also in a polygonal shape corresponding to the flexible display screen 10 and are attached to the outer edge of the flexible display screen 10, which is not limited herein.

In some embodiments, each signal emitter 50 is disposed at a corner of the flexible display screen 10, the corner is a junction of two adjacent outer edges of the flexible display screen 10, as shown in fig. 3, in this embodiment, the flexible display screen 10 includes a pair of first parallel sides 11 and a pair of second parallel sides 12 perpendicular to the first sides, and a pair of the first sides 11 and a pair of the second sides 12 enclose a rectangle. The plurality of sensors 10 are respectively disposed in the flexible display screen 10 along a pair of first sides 51 and a pair of second sides 52. The number of the signal emitters 50 is 4, and each signal emitter 50 is disposed at a corner of the flexible display screen 10, where the corner is where the first side 11 and the second side 12 intersect. In the present embodiment, the signal emitter 50 is a light emitter which generates a light ray in a single direction, and the light ray is parallel to the distribution direction of the corresponding plurality of sensors 40 and does not intersect with the plurality of sensors 40. For example, the light emitted by the first signal emitter 50 is parallel to the first side 11, and the light emitted by the second signal emitter 50 is parallel to the second side 12, so that the propagation direction of the emitted signal generated by each signal emitter 50 is enclosed to form a shape consistent with the flexible display screen 10.

In some embodiments, the "determining a bending position where the flexible display device is bent according to the coordinates of the target sensor" includes:

and when the number of the edges of the flexible display screen where the coordinates are located is equal to 2 and the number of the determined coordinates is 2, determining the bending position of the flexible display device according to at least two coordinates.

In this embodiment, when the number of sides of the flexible display screen where the coordinates are located is greater than 2 or less than 2, it is determined that the coordinates of the target sensor are invalid, and the bending position determination method is restarted.

In other embodiments, when the number of sides of the flexible display screen where the coordinates are located is equal to 2 and the determined number of the coordinates is greater than 2, determining whether a distance between coordinates of the object sensors 40 on the same side of the flexible display screen is within a threshold range;
