The processor 30 is electrically connected to the plurality of sensors 40 and the at least one signal transmitter 50, respectively. Those skilled in the art should understand that FIG. 1 is only an example of the flexible display device 100 and does not constitute a limitation on the flexible display device 100. The flexible display device 100 may include more than that shown in FIG. More or less components, or a combination of certain components, or different components, for example, the flexible display apparatus 100 may further include input and output devices, network access devices, and the like.

The memory 20 may be used to store computer programs and / or modules. The processor 30 executes or executes the computer programs and / or modules stored in the memory 20 and calls the data stored in the memory 20 to achieve The various functions of the flexible display device 100 will be described. 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 required for multiple functions (such as a sound playback function, an image playback function, etc.), etc .; the data storage area may Store data created according to the use of mobile phones (such as audio data, phone book, etc.), etc.

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

Wherein, the size of the sensing data generated by the plurality of sensors 40 is proportional to the intensity of the received transmission signal. For example, when the sensor 40 does not receive the transmitted signal, no sensing data is generated; when the sensor 40 receives a weak sensing signal, the generated sensing data is smaller; when the sensor receives When a stronger signal is transmitted, it generates larger sensing data.

In this embodiment, when the flexible display device 100 is not bent, the plurality of sensors 10 cannot receive the transmission signal generated by the signal transmitter 50, so no sensing data is generated; when the When the flexible display device 100 is bent, the sensor 10 located in the bent area can receive the emission signal generated by the signal transmitter 50 to generate sensing data. In other embodiments, when the flexible display device 100 is not bent, the plurality of sensors 10 may receive the emission signal generated by the signal transmitter 50, and when the flexible display device 100 is bent At this time, the transmission signal generated by the signal transmitter 70 cannot be received.

The flexible display device 100 disclosed in the embodiments of the present application includes at least one signal transmitter 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 transmission signal. Furthermore, when the flexible display device 100 is bent, the sensing data of the sensor 10 at the bending position will change. Therefore, the processor 30 acquires the sensing data of the multiple sensors 10, and according to the sense The coordinates of the target sensor 10 whose measured data changes can determine the bending line of the flexible display device 100, and thus can 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, the flexible display device 100 can be controlled through different bending positions to achieve different interactive functions, thereby improving the user's experience with the flexible display device 100.

Referring again 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. Specifically, the sensor 40 may be disposed at the inner surface of the flexible display screen 10 facing the housing 70 or / and on the outer surface facing away from the housing 70. Similarly, the sensor 40 may also be disposed at the inner surface of the housing 70 facing the flexible display screen 10 or / and on the 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), the flexible circuit board is disposed between the flexible display screen 50 and the housing 60, and the plurality of sensors 10 is disposed on the flexible circuit board and is attached to the inner surface of the flexible display screen 50 or the housing 60.

In this embodiment, 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. The shape formed after the plurality of sensors 40 are disposed at the outer edge of the flexible display screen 10 is adapted to the shape of the flexible display screen 10. For example, when the flexible display screen 10 is rectangular, the plurality of sensors 40 are also rectangularly attached to the outer edge of the flexible display screen 10; when the flexible display screen 10 is circular, the multiple The sensors 40 are also circularly attached to the outer edge of the flexible display screen 10; when the flexible display screen 10 is a polygon, the multiple sensors 40 also take a polygon corresponding to the flexible display screen 10 It is attached to the outer edge of the flexible display screen 10 and is not limited herein.

Specifically, a two-dimensional rectangular coordinate system can be established using the surface of the flexible display screen 10 when it is not bent as a coordinate plane, and a certain point on the flexible display screen 10 as the coordinate origin, when the coordinate origin is determined The coordinates of each sensor 10 relative to the origin of the coordinates are also determined accordingly. Therefore, as long as the target sensor 10 whose sensing data has changed is found, the bending line where the bending occurs can be determined according to its coordinates.

In some embodiments, the number of the signal transmitters 50 is the same as the number of outer edges of the flexible display screen 10, and one signal transmitter 50 is provided on each side of the flexible display screen 10, so The plurality of sensors 40 are disposed on the outer edge of the flexible display screen 10, each signal transmitter 50 generates a single direction of the transmission signal, and the propagation direction of the transmission signal generated by each signal transmitter 50 is parallel to its Outer edge. When the flexible display screen 10 is not bent, the propagation direction of the transmitted signal does not intersect with the sensor 40 provided on the outer edge where the signal transmitter 50 is located; when the flexible display screen 10 is bent, The propagation direction of the transmitted signal intersects a sensor 40 on the outer edge where the signal transmitter 50 is located.

Please refer to FIG. 3 again. In this embodiment, the flexible display screen 10 includes a pair of mutually parallel first side edges 11 and a pair of mutually parallel second side edges 12 perpendicular to the first side edges A pair of the first side 11 and a pair of the second side 12 form a rectangle. The plurality of sensors 10 are built into the flexible display screen 10 along a pair of first sides 51 and a pair of second sides 52 respectively. The number of the signal transmitters 50 is four, and each signal transmitter 50 is disposed at a corner of the flexible display screen 10, wherein the corner refers to the first side 11 and the first The intersection of the two sides 12. In this embodiment, the signal transmitter 50 is a light transmitter, and the light transmitter generates light in a single direction, and the light is parallel to the distribution direction of the corresponding multiple sensors 40 and not parallel to the multiple The sensor 40 intersects. For example, the light emitted by the first signal transmitter 50 is parallel to the first side 11, and the light emitted by the second signal transmitter 50 is parallel to the second side 12, thereby making the emission generated by each signal transmitter 50 The signal propagation direction forms a shape consistent with the flexible display screen 10.

In this embodiment, the sensor 10 is a photosensitive sensor. When the light sensor receives the light emitted by the signal transmitter 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 that the photosensitive sensor generating the sensing data is a target sensor whose sensing data changes.

For example, when the light sensor does not receive light, it has no voltage output, that is, the output voltage is 0; when the light sensor receives light, there will be a voltage output and the output voltage will vary with the strength 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 a certain photosensitive sensor, it can determine that the photosensitive sensor that generates the sensing data is the target sensor and acquire the coordinates of the target sensor. When two photosensitive sensors generate the sensing data, That is, a straight line is determined by the coordinates of the two photosensitive sensors, and the straight line is the bending line of the flexible display device 100. In addition, since the plurality of photosensitive sensors 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 photosensitive sensors receive The light emitted by the signal transmitter 50 causes the sensing data to change, so that the bending line where the flexible display device 100 is bent can be determined.

4 again, when the flexible display screen 10 is not bent, the light emitted by the signal transmitter 50 propagates in a direction parallel to the plane where the flexible display screen 10 is located (see the arrow direction in FIG. 4). Therefore, when the flexible display device 100 is not bent, the plurality of photosensitive sensors theoretically will not receive light, but in fact, due to the presence of the medium in the air, the light will be refracted, so that the sensor receives Slight light, but the voltage signal generated by this weak light is weak and can be ignored.

Referring to FIG. 5, when the flexible display device 100 is bent, the light emitted by the signal emitter 50 enters the photosensitive sensor located at the bent position, and the photosensitive sensor receives the light emitted by the signal emitter 50 The light generates a voltage signal, and sends the generated voltage signal to the processor 30. For example, please refer to FIG. 3 together, when the flexible display device 100 is bent along the bending line L, one photosensor distributed along one of the first sides 11 and one photosensor distributed along the other of the first sides 11 The light emitted by the signal transmitter 50 will be received to generate a voltage signal. The processor 30 can determine the coordinate of one of the photosensors as (x1, y1) and the coordinate of the other photosensor as (x2, y2) according to the received voltage signal, so that the position of the bending line L can be obtained. It can be understood that the distance between the plane formed by the light emitted by the signal transmitter 50 and the plane formed by the plurality of sensors 10 may be set according to specific design requirements, and is not limited herein.

In one embodiment, in order not to affect the user's visual experience, the signal transmitter 50 is used to emit invisible light. Wherein, the invisible light includes ultraviolet rays, infrared rays, far infrared rays and the like. Preferably, the light emitted by the signal transmitter 50 is infrared light with strong penetrating power, and the photosensitive sensor for receiving infrared light has the advantage of high sensitivity.

In other embodiments, the signal transmitter 50 emits light in multiple directions, the light forms a coverage area in the same plane, the plane formed by the multi-directional light and the plane of the initial state of the flexible screen 10 (without bending) It is parallel and parallel to the plane where the sensor 40 is located. The coverage area covers the area where the flexible display screen 10 is provided with the sensor 10, so that any light-sensitive sensor can receive the light emitted by the signal transmitter 50 as long as the position changes, thereby improving the determination of the position of the bending line Accuracy.

6 again, 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 The dot matrix is distributed on the flexible substrate 80 and closely adheres to the flexible display screen 10, that is, a photosensitive map of each point constitutes a coordinate map of sensing points. Therefore, after receiving the sensing data transmitted from the photosensitive sensor array, the processor 30 can filter out the photosensitive sensors that generate the sensing data, and determine its coordinates to determine the bending line of the flexible display device 100, thereby improving the determination Accuracy of bending position.

In this embodiment, the shape of the flexible substrate 80 is consistent with the shape of the flexible display screen 10. When there is only one signal transmitter 50, the bending position can be determined. It should be noted that when the flexible display screen 10 is bent, the multiple sensors 40 at the bent position will receive the transmission signal, that is, the sensing data of the multiple sensors 40 will change. Therefore, the The bending line determined by the coordinates of the multiple 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 of a method for determining a bending position disclosed in this application. The method for determining the bending position is applied to the flexible display device 100, and the flexible display device 100 includes at least one signal transmitter 50 and a plurality of sensors 40. Each sensor corresponds to a coordinate position. The method for determining the bending position includes the following steps:

Step S71: Obtain the sensing data generated by the multiple sensors, and determine the coordinates of the target sensor whose sensing data changes according to the acquired sensing data.

Step S72: Determine the bending position of the flexible display device according to the coordinates of the target sensor.

The method for determining the bending position disclosed in the embodiment of the present application, because the flexible display device 100 includes at least one signal transmitter 50 and a plurality of sensors 40, and the plurality of sensors 40 can depend on the strength of the received transmission signal The corresponding sensing data is generated, so that when the flexible display device 100 is bent, the sensing data of the sensor 10 located at the bending line will change. Therefore, the processor 30 obtains multiple sensors 10 by Sensing the data, and according to the coordinates of the target sensor 10 where the sensing data changes, the bending line of the flexible display device 100 can be determined, so that the bending position of the flexible display device 100 can be determined. In this way, the flexible display device 100 can be controlled according to the bending position, for example, the flexible display device 100 can be controlled through different bending positions to achieve different interactive functions, thereby improving the user's experience with the flexible display device 100.

Please refer to FIG. 8, which shows a sub-flow diagram of step S71 in an embodiment of the present application. In this embodiment, step S71 specifically includes the following steps:

Step S711: Acquire sensing data of the multiple sensors.

In step S712, it is determined whether the acquired sensing data has changed; if so, step S713 is entered; if not, the flow ends.

In this embodiment, when the flexible display device 100 is not bent, the multiple sensors 10 do not receive the transmission signal generated by the signal transmitter 50 without generating sensing data; when the flexible When the display device 100 is bent, the sensor 10 located in the bent area receives the emission signal generated by the signal transmitter 50 to generate sensing data. In other embodiments, when the flexible display device 100 is not bent, the plurality of sensors 10 may receive the emission signal generated by the signal transmitter 50, and when the flexible display device 100 is bent At this time, the transmission signal generated by the signal transmitter 50 cannot be received.

Step S713: Determine that the sensor whose sensing data has changed is a target sensor, and determine the coordinates of the target sensor.

In this embodiment, the flexible display device 100 further includes a flexible display screen 10. Specifically, a two-dimensional rectangular coordinate system can be established using the surface of the flexible display screen 10 when no bending occurs as a coordinate plane, and A certain point on the flexible display screen 10 is a coordinate origin. When the coordinate origin is determined, the coordinates of each sensor 10 relative to the coordinate origin are also determined accordingly. Therefore, as long as the target sensor whose sensing data changes is found 10. According to its coordinates, the bending line can be determined.

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 shape formed after the multiple sensors 40 are disposed at the outer edge of the flexible display screen 10 is adapted to the shape of the flexible display screen 10. For example, when the flexible display screen 10 is rectangular, the plurality of sensors 40 are also rectangularly attached to the outer edge of the flexible display screen 10; when the flexible display screen 10 is circular, the multiple The sensors 40 are also circularly attached to the outer edge of the flexible display screen 10; when the flexible display screen 10 is a polygon, the multiple sensors 40 also take a polygon corresponding to the flexible display screen 10 It is attached to the outer edge of the flexible display screen 10 and is not limited herein.

In some embodiments, each signal transmitter 50 is disposed at a corner of the flexible display screen 10, and the corner is the intersection of two adjacent outer edges of the flexible display screen 10, as shown in FIG. 3 It is shown that in this embodiment, the flexible display screen 10 includes a pair of first side edges 11 parallel to each other and a pair of parallel second side edges 12 perpendicular to the first side edges. The first side 11 and the pair of second sides 12 form a rectangle. The plurality of sensors 10 are built into the flexible display screen 10 along a pair of first sides 51 and a pair of second sides 52 respectively. The number of the signal transmitters 50 is four, and each signal transmitter 50 is disposed at a corner of the flexible display screen 10, wherein the corner refers to the first side 11 and the first The intersection of the two sides 12. In this embodiment, the signal transmitter 50 is a light transmitter, and the light transmitter generates light in a single direction, and the light is parallel to the distribution direction of the corresponding multiple sensors 40 and not parallel to the multiple The sensor 40 intersects. For example, the light emitted by the first signal transmitter 50 is parallel to the first side 11, and the light emitted by the second signal transmitter 50 is parallel to the second side 12, thereby making the emission generated by each signal transmitter 50 The signal propagation direction surrounds the shape consistent with the flexible display screen 10.
