All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

Referring to fig. 1-2, an embodiment of the present application discloses a flexible electronic device 100. The flexible electronic 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 electronic device 100 refers to an electronic device with a flexible and bendable screen. Such electronic devices can be bent, so that when using the flexible electronic device 100, a user can bend the flexible electronic device into a desired shape to adapt the shape of the flexible electronic device to the current use requirement. On the other hand, when the flexible electronic device 100 is not needed, the user can also reduce the occupied space by bending, and the portability is improved.

In some embodiments, the flexible electronic device 100 includes a flexible display screen 10, and the flexible display screen 10 may be an Organic Light-Emitting Diode (OLED) flexible display screen, which has characteristics of being bendable, twistable, and foldable, and meanwhile, has characteristics of better color and contrast, and being ultra-thin.

In this embodiment, the flexible display has a bending region 11. When the flexible electronic device 100 is in a folded state, the display area of the flexible display screen 10 is divided into a main screen area 12 and an auxiliary screen area 13 by the bending area 11, and the directions of the main screen area 12 and the auxiliary screen area 13 are opposite. When the flexible electronic device 100 is in an unfolded state, the main screen area 12, the bending area 11 and the auxiliary screen area 13 form a continuous plane. The folded state is that an included angle between two parts of the flexible electronic device 100 divided by the bending region 11 is less than 180 degrees; when the included angle between the two parts is 180 degrees, the flexible electronic device 100 is in the unfolded state. Wherein the angle can be obtained by an angle sensor (not shown) arranged at the bending zone 11.

In some embodiments, the bending region 11 defines a folding line 101, and the bending region 11 is divided into a first side panel region 111 and a second side panel region 112 by the folding line 101, wherein the main panel region 12 connects the first side panel region 111 and the secondary panel region 13 connects the second side panel region 112. When the flexible electronic device 100 is in a folded state, the first side panel 111 and the second side panel 112 of the bending region 11 form a continuous arc. When the flexible electronic device 100 is in an unfolded state, the first side screen area 111 and the second side screen area 112 of the bending area 11 form a continuous plane.

In another embodiment, when the flexible display screen 10 is in the unfolded state, the whole display area of the flexible display screen 10 is divided into two sub-display areas 102 by the folding line 101. Wherein the two sub-display areas 101 are located at two opposite sides of the folding line 101. That is, the main screen area 12 and the first side screen area 111 connected thereto form one sub-display area 102, and the auxiliary screen area 13 and the second side screen area 112 connected thereto form another sub-display area 103.

Referring to fig. 3 again, fig. 3 is a flowchart of a screen switching method according to an embodiment of the present application. The screen switching method is applied to the flexible electronic device 100, and the screen switching method in the embodiment of the present application is described in detail below.

It should be noted that when the flexible electronic device 100 is in the folded state, only one screen is in the state facing the user, and in order to save energy consumption, the sub-display area 102 facing the user is usually in the bright screen state for the user to use, and the sub-display area 103 facing away from the user is in the off screen state.

Step S31, when the flexible electronic device 100 is in the folded state, identifying whether the operation mode of the flexible electronic device 100 is the single-screen lighting mode. In the single-screen lighting mode, one of the main screen area 12 and the auxiliary screen area 13 is in a lighting state, and the other of the main screen area 12 and the auxiliary screen area 13 is in a screen-off state. If yes, go to step S32; if not, the process ends.

Referring to fig. 1 again, in some embodiments, the flexible electronic device 100 is provided with a distance sensor 20 on one of the main screen area 12 or the auxiliary screen area 13. The distance sensor 20 is configured to generate and emit optical signals, and the distance sensor 20 is further configured to receive optical signals obtained by reflecting the emergent light by the blocking object, and output corresponding sensing information according to the intensity of the received optical signals. In this embodiment, the optical signal is invisible light, such as infrared light, ultraviolet light, and the like.

In some embodiments, the distance sensor 20 is disposed on a side wall of the main screen area 12 or the auxiliary screen area 13, and is configured to detect a shelter on the side of the main screen area 12 or the shelter on the side of the auxiliary screen area 13.

In other embodiments, the distance sensor 20 may be disposed in the flexible electronic device 100 and facing the main screen area 12 or the auxiliary screen area 13. In this embodiment, the main screen area 12 or the auxiliary screen area 13 of the flexible display screen 10 needs to be provided with a through hole 103, and the distance sensor 20 is disposed in the flexible electronic device 100 and corresponds to the through hole 103, so that the distance sensor 20 can detect a shielding object on the side of the main screen area 12 or a shielding object on the side of the auxiliary screen area 13 by transmitting and receiving signals through the corresponding through hole 103. Preferably, the through hole 103 is opened at the edge of the flexible display screen 10 to reduce the influence on the screen display.

It is understood that the electronic device 100 further includes a housing 200 (see fig. 2) disposed opposite to the flexible display screen 10, and the housing 200 and the flexible display screen 100 enclose a space for accommodating electronic components (e.g., a circuit board). The distance sensor 20 is disposed in the flexible electronic device 100, which means that the distance sensor 20 is disposed in a space enclosed by the flexible display screen 100 and the housing 200. Specifically, the distance sensor 20 may be disposed on a circuit board (not shown), for example, soldered on the circuit board, and further electrically connected to other electronic components and the main control chip on the circuit board.

In one embodiment, the distance sensor 20 is an infrared distance measuring sensor. The infrared distance measuring sensor is used for generating an infrared light signal. When there is a shield on one side of the primary screen area 12 or one side of the secondary screen area 13, the distance sensor 20 receives the infrared light signal reflected by the shield. Wherein, the closer the shield (such as a face or a finger) is to the flexible display screen 10, the stronger the signal intensity of the reflected light received by the distance sensor 20. For example, the distance sensor 20 may include a light emitter for generating and emitting a light signal and a photo sensor for receiving the light signal reflected by the obstruction and outputting corresponding sensing information according to the intensity of the received infrared light signal. The sensing information may be a voltage signal or a current signal, and when the intensity of the received light signal is stronger, the output sensing information is stronger, so that the distance between the shielding object and the distance sensor 20 can be calculated according to the strength of the sensing information. In other embodiments, the distance sensor 20 may be an optical displacement sensor, a linear proximity sensor, an ultrasonic displacement sensor, or the like.

The preset distance may be determined according to specific design requirements, for example, the preset distance value may be 1cm, 2cm, 5cm, 10cm, and the like, which is not limited herein.

Step S32, determining whether the sensing information generated by the distance sensor changes. If yes, go to step S33; if not, the process ends.

In the present embodiment, when the flexible electronic device 100 enters the single-screen lighting mode, one of the main screen area 12 or the auxiliary screen area 13, which is not provided with the distance sensor 20, is in a lighting state by default. For example, when the distance sensor 20 is not disposed on one side of the main screen area 12, when the flexible electronic device 100 enters the single-screen lighting mode, the default main screen area 12 is in the lighting state, and the auxiliary screen area 13 is in the off-screen state, that is, the main screen area 12 may face the user for use. When the auxiliary screen area 13 provided with the distance sensor 20 faces the user, the distance sensor 20 detects a blocking object (such as the face of the user) to cause a change in the sensing information, and thus, according to the change in the sensing information of the distance sensor 20, it can be determined that the screen facing the user has changed.

Step S33, controlling to switch one of the main screen area 12 and the auxiliary screen area 13 in the bright screen state to the off screen state, and switching one of the main screen area 12 and the auxiliary screen area 13 in the off screen state to the bright screen state.

In some embodiments, when the main screen area 12 is lit, the first cambered side screen area 111 is lit, and when the auxiliary screen area 13 is extinguished, the second cambered side screen area 112 is also extinguished. When the auxiliary screen area 13 is lighted, the second side screen area 112 in the arc shape is also lighted, and when the main screen area 12 is turned off, the first side screen area 111 in the arc shape is also turned off.

In the screen switching method disclosed in the embodiment of the application, since the flexible electronic device 100 is provided with the distance sensor 20 on one side of the main screen area 12 or one side of the auxiliary screen area 13, when it is determined that the sensing information generated by the distance sensor changes, the main screen area 12 and the auxiliary screen area 13, which are in the bright screen state, are controlled to be switched to the off screen state, and the main screen area 12 and one side of the auxiliary screen area 13, which are in the off screen state, are switched to the bright screen state, so that the screen switching method is simpler and more convenient for users to use, thereby improving user experience.

Referring to fig. 4 again, fig. 4 is a flowchart of a screen switching method in another embodiment of the present application. In this embodiment, the flexible electronic device 100 is provided with the distance sensor 20 on both the main screen area 12 and the auxiliary screen area 13, and is configured to detect a shielding object on the side of the main screen area 12 and a shielding object on the side of the auxiliary screen area 13 respectively. The screen switching method includes the following steps.

Step S41, when the flexible electronic device 100 is in the folded state, identifying whether the operation mode of the flexible electronic device 100 is the single-screen lighting mode. In the single-screen lighting mode, one of the main screen area 12 and the auxiliary screen area 13 is in a lighting state, and the other of the main screen area 12 and the auxiliary screen area 13 is in a screen-off state. If yes, go to step S42; if not, the process ends.

Step S41 is the same as step S31, and is not described herein again.

In step S42, it is determined whether the screen currently in the lit state is the main screen area 12 or the sub screen area 13. When the main screen area 12 is in the lighting state, executing step S43; when the secondary screen area 13 is in the lit state, step S45 is executed.

Step S43, it is determined whether the sensing information generated by the distance sensor 20 on the main screen area 12 changes. If yes, go to step S44; if not, the process is ended.

Step S44, controlling to switch the main screen area 12 in the bright screen state to the off screen state, and controlling to switch the auxiliary screen area 13 in the off screen state to the bright screen state.

Step S45, determining whether the sensing information generated by the distance sensor 20 on the secondary screen area 13 changes. If yes, go to step S46; if not, the process is ended.

Step S32 includes step S43 and step S45.

Step S46, controlling to switch the auxiliary screen area 13 in the bright screen state to the off screen state, and switching the main screen area 12 in the off screen state to the bright screen state.

Step S33 includes step S44 and step S46.

In this embodiment, since the flexible electronic device 100 is in the single-screen lighting mode, if the main screen area 12 is in the lighting state, it indicates that the main screen area 12 is in the use state and faces the user; if the auxiliary screen area 13 is in the lit state, it indicates that the auxiliary screen area 13 is in the use state and faces the user. Therefore, the face of the user can block the distance sensor 20 on the side of the main screen area 12 or the auxiliary screen area 13 in the lighting state, so that the distance sensor 20 generates corresponding sensing information. When the user wants to switch the screen, the face of the user leaves the current screen, and the information generated by the current distance sensor 20 changes due to the movement of the face of the user. Therefore, no matter the main screen area 12 or the auxiliary screen area 13 faces the user, no other operation is needed, the purpose of screen switching can be achieved, and user experience is further improved. In addition, if the user changes the sensing information generated by the distance sensor 20 by blocking the distance sensor 20 with a finger, the user can operate the lighted screen with a finger even when using the flexible electronic device 100, and therefore, it is convenient to directly perform the blocking operation while switching the screen.

In the above embodiments, although the purpose of switching the screen may be achieved by a change in the sensing information generated by the distance sensor 20, there may be a case where the determination is erroneous. For example, when the face of the user leaves the main screen area 12 currently in the lighting state, the user does not turn over to change the state of the flexible electronic device 100, and only leaves the flexible electronic device temporarily, and if the main screen area 12 in the lighting state is controlled to be switched to the screen-off state in this case, the experience of the user is affected. Therefore, referring to fig. 5 again, in order to avoid the occurrence of the misjudgment situation, in some embodiments, the screen switching method further includes the following steps after step S32 compared to the method in fig. 3:

step S51, determining whether the duration of the change of the sensing information is longer than a preset time. If yes, go to step S52; if not, the process ends.

In the present embodiment, since the duration of change of the sensing information is determined, it is possible to avoid erroneous determination due to inadvertent separation or blocking during operation.

In step S52, it is determined whether the state of the flexible electronic device 100 has changed. If yes, go to step S33; if not, the process ends.

The state of the flexible electronic device 100 includes a placement state or a holding state of the flexible electronic device 100. When the placement state or the holding state of the flexible electronic device 100 is changed, it is determined that the state of the flexible electronic device 100 is changed. Specifically, when the flexible electronic device 100 is in the placement state, the state is changed, that is, the placement direction is changed; when the flexible electronic device 100 is in the holding state, the state is changed, that is, the holding direction is changed.

In some embodiments, the flexible electronic device 100 further comprises a sensing device 30 (see fig. 7). The determining whether the state of the flexible electronic device 100 has changed includes: the sensing data output by the sensing device 30 is acquired, and whether the state of the flexible electronic device 100 is changed is determined according to the sensing data output by the sensing device.

In some embodiments, the sensing device 30 includes a gravity sensor (PS: modified to include, one or more, or one that can be sensed, and the Z-axis data can be changed whenever flipped, whether on the primary or secondary screen). The gravity sensor is used for sensing gravity data of the flexible electronic device 100. The determining whether the state of the flexible electronic device 100 has changed according to the sensing data output by the sensing device 30 includes: and judging whether the state of the flexible electronic device 100 is changed or not according to the direction change of the Z-axis data of the gravity sensor. When the Z-axis data of the gravity sensor changes from positive to negative or negative to positive, it is determined that the state of the flexible electronic device 100 has changed.

For example, the main screen area 12 of the flexible electronic device 100 is provided with a gravity sensor, and when the flexible electronic device 100 is in the first state, that is, the main screen area 12 faces the user, and the auxiliary screen area 13 faces away from the user, the data of the Z-axis sensed by the gravity sensor is positive (upward); when the flexible electronic device 100 is switched from the first state to the second state, that is, the flexible electronic device 100 is flipped over such that the auxiliary screen area 13 faces the user and the main screen area 12 faces away from the user, the Z-axis data sensed by the gravity sensor is negative (downward).

In other embodiments, the sensing device 30 may further include one of an acceleration sensor and a direction sensor. In addition, for the accuracy of the determination, the sensing device 30 may further include any two or more of a gravity sensor, a direction sensor, or an acceleration sensor.

In another embodiment, the sensing device 30 includes a plurality of pressure sensors for sensing pressure data when the flexible electronic device 100 is touched, and the plurality of pressure sensors are distributed at different positions of the flexible electronic device 100. For example, the plurality of pressure sensors are distributed at different positions of the flexible display screen 10 (one part is located in the main screen area 12, and the other part is located in the auxiliary screen area 13) and at different positions of the side of the flexible electronic device 100. The determining whether the state of the flexible electronic device 100 has changed according to the sensing data output by the sensing device 30 includes: and judging whether the state of the flexible electronic device 100 is changed or not according to the pressure data generated by the plurality of pressure sensors in response to the pressing.

Wherein the pressure data comprises at least one of: the number of pressure points, the duration of the pressure and the magnitude of the pressure.

As shown in fig. 6, when the flexible electronic device 100 is in the folded state, if the main screen area 12 faces the user and the auxiliary screen area 13 faces away from the user, the pressure sensor on the main screen area 12 facing the user generally does not respond to the continuous pressing, and the pressure sensor on the auxiliary screen area 13 facing away from the user continuously generates pressure data due to the long-time holding of the fingers when the user normally uses the electronic device. Therefore, the pressure sensor on the main screen 12 generates pressure data with a smaller number of pressure points, a shorter time and a smaller pressure, while the pressure sensor on the sub screen 13 generates pressure data with a larger number of pressure points, a longer duration and a larger pressure due to a larger area of contact with the user's finger. When the holding posture of the user is changed, that is, the auxiliary screen area 13 faces the user and the main screen area 12 faces away from the user, the number of pressure points of the pressure data generated by the pressure sensor located on the auxiliary screen area 13 is small, and the number of pressure points of the pressure data generated by the pressure sensor located on the main screen area 12 is large due to the large area in contact with the finger of the user, the duration is long, and the pressure is large. That is to say, when the state of the flexible electronic device 100 changes, the pressure data generated by the pressure sensors located at different positions on the flexible display screen 10 changes, and therefore, it can be determined whether the holding posture of the flexible electronic device 100 has changed according to the pressure data generated by the pressure sensors in response to pressing, and further, whether the state of the flexible electronic device 100 has changed.

Please refer to fig. 7, which is a block diagram illustrating a flexible electronic device 100 according to an embodiment of the present application.
