The mobile terminal 100 may be, but is not limited to, a bendable electronic terminal such as a mobile phone, a tablet computer, an electronic reader, a wearable electronic device, and the like. The mobile terminal 100 includes, but is not limited to, a processor 10, and a memory 20, a flexible display 30 and a screen bending sensor 60 electrically connected to the processor 10, respectively. It should be understood by those skilled in the art that the mobile terminal 100 shown in fig. 1 is only an example of the mobile terminal 100 and does not constitute a limitation to the mobile terminal 100, and that the mobile terminal 100 may include more or less components than those shown in fig. 1, or may combine some components, or different components, for example, the mobile terminal 100 may further include an input and output device, a network access device, a data bus, etc.
The Processor 10 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 general-purpose processor may be any conventional processor or the like, and the processor 10 is a control center of the mobile terminal 100 and connects various parts of the entire mobile terminal 100 using various interfaces and lines.
The memory 20 may be used to store the computer programs and/or modules, and the processor 10 implements various functions of the mobile terminal 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 by a plurality of functions, and the like; the storage data area may store data (such as audio data, image data, etc.) created according to the use of the mobile terminal, etc. 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.
Referring to fig. 2, fig. 2 is a schematic structural diagram of the mobile terminal 100 in an unfolded state according to an embodiment of the present application. The flexible display 30 is bendable along at least one bending line EF. The screen bending sensor 60 senses whether the flexible display screen 30 is bent at a changed angle. The processor 10 switches a target screen when the screen bending sensor 60 senses a change in a bending angle of the flexible display screen 30, wherein the target screen is the flexible display screen 30 or a part of the flexible display screen 30 and is used for displaying content.
Therefore, the present application can switch the target screen and control the display content of the target screen when the screen bending sensor 60 senses the change of the bending angle of the flexible display screen 30. Therefore, whether screen switching is needed or not can be judged intelligently according to the bending behavior of the flexible display screen 30 by a user, the screen switching is more intelligent, and the user experience is enhanced.
The processor 10 further determines the screen folding state of the flexible display screen 30 at the corresponding bending line EF according to the bending angle at each bending line EF sensed by the screen bending sensor 60. Wherein the screen folded state is one of a bent state and an unfolded state. The bending state is a state where the flexible display 30 is bent at a position corresponding to the bending line EF. The unfolded state is a state in which the flexible display 30 is completely unfolded without being bent at the corresponding bending line EF. The processor 10 further switches the target screen when the bending angle of the flexible display screen 30 changes at the position corresponding to the bending line EF and the screen folding state changes, such as the screen folding state is switched from the unfolded state to the bent state or from the bent state to the unfolded state.
The processor 10 determines that the screen folding state corresponding to each bending line EF of the flexible display screen 30 is an unfolded state, that is, when the flexible display screen 30 is in the unfolded state at each bending line EF, it is determined that the whole screen of the flexible display screen 30 is the target screen, and the display content of the target screen is controlled.
The flexible display 30 is bent along at least one bending line EF to form at least two sub-screens. The divided screens refer to screen portions currently located on the same continuous plane, for example, when the flexible display 30 has two bending lines and is bent along the two bending lines, respectively, the flexible display 30 includes three divided screens, but if the flexible display 30 is bent along only one of the bending lines, the flexible display 30 includes only two divided screens, and thus the divided screens are a dynamic concept, that is, the number of the divided screens and the size of each divided screen of the flexible display 30 are both related to the screen folding state according to each bending line.
Further, when the included angle between two adjacent sub-screens of at least two sub-screens formed by bending the flexible display screen 30 along the bending line in opposite directions is smaller than or equal to a preset threshold, the processor 10 determines that the two adjacent sub-screens are both non-target screens. The phrase "the flexible display screen 30 is bent towards each other along the bending line" means that the flexible display screen 30 is folded inwards so that the display surfaces of the adjacent sub-screens after bending are opposite to each other, so that the flexible display screen 30 is prevented from being damaged when not in use. In one non-limiting embodiment, the predetermined threshold is 90 degrees or 60 degrees.
Specifically, the at least two sub-screens include a first screen 31 and at least one second screen 33. In this embodiment, the flexible display 30 includes a second screen 33. The second screen 33 extends from one side of the first screen 31, and in the expanded state shown in fig. 2, the first screen 31 and the second screen 33 are located on the same plane and oriented in the same direction; in the bending state not shown in fig. 2, the first screen 31 and the second screen 33 can be bent along a bending line EF connecting the first screen 31 and the second screen 33 as an axis, that is, the first screen 31 and the second screen 33 are formed by bending large screens along the corresponding bending line EF. It will be appreciated that in other embodiments the first screen 31 is connected to the second screen 33 on one side, i.e. the first screen 31 and the second screen 33 are connected by two separate screens.
The screen bending sensor 60 is disposed between the first screen 31 and the second screen 33 corresponding to each bending line EF. The screen bending sensor 60 senses a bending angle between the first screen 31 and the second screen 33. The processor 10 can determine the screen folding state between the first screen 31 and the second screen 33 corresponding to each folding line EF according to the folding angle sensed by the screen folding sensor 60. As described above, the screen folded state includes the unfolded state and the folded state. It can be understood that, in an embodiment, the unfolded state refers to a state where the bending angle is between 0 to 30 degrees, and at this time, the first screen 31 and the second screen 33 are substantially completely unfolded and located on the same plane. The bending state is a state in which the bending angle is 30 to 180 degrees, and at this time, the first screen 31 is bent relative to the second screen 33. The bending angle is an angle between the display surfaces of the first screen 31 and the second screen 33. It is understood that, in other embodiments, the angle ranges defined for the bending state and the unfolding state may be adjusted according to actual needs, and are not limited herein.
Further, the mobile terminal 100 further includes a sensing unit for sensing a status parameter of each sub-screen of the flexible display screen 30, respectively. When the bending angle of the target screen at the corresponding bending line EF changes and the screen folding state at the bending line EF is switched from the unfolded state to the bent state, the processor 10 determines the sub-screen with the minimum state change as the target screen according to the initial state and the final state of each sub-screen sensed by the sensing unit, and controls the display content of the target screen.
Specifically, the processor 10 obtains an initial state parameter and a final state parameter of a corresponding sub-screen sensed by each sensing unit in real time; and calculating the difference value between the initial state parameter and the final state parameter of each sub-screen, determining the sub-screen with the minimum difference value as the target screen, and controlling the display content of the target screen.
Specifically, the at least two sensing units include a first sensing unit 40 and at least one second sensing unit 50. The first sensing unit 40 is connected to the first screen 31 and senses the state of the first screen 31 in real time. The at least one second sensing unit 50 is respectively disposed on the at least one second screen 33, and senses the state of the corresponding second screen 33 in real time. In this embodiment, the second sensing units 50 are disposed in one-to-one correspondence with the second screens 33. As can be appreciated. In other embodiments, at least one second sensing unit 50 is disposed on a second screen 33.
It is understood that the first sensing unit 40 and the second sensing unit 50 referred to herein generally refer to a set of respective sensing devices for sensing a screen state, and do not specifically refer to a certain one or a certain kind of sensing devices. Specifically, the first sensing unit 40 and/or the second sensing unit 50 may include a sensor for sensing an orientation of the first screen 31 and/or the second screen 35 and a sensor for sensing a gravitational acceleration of the first screen 31 and/or the second screen 35. As above, for exemplary purposes only, the first sensing cell 40 and/or the second sensing cell 50 may also include more or fewer sensing devices.
When the screen bending sensor 60 senses that the bending angle of the flexible display screen 30 changes, the processor 10 determines whether the screen folding state at the bending line is switched from the unfolded state to the bending state according to the bending angle, and if so, acquires the initial state parameters of the corresponding sub-screen sensed by each sensing unit in real time. When the screen bending sensor 60 senses that the flexible display screen 30 stops bending, the processor 10 obtains the final state parameters of the corresponding sub-screen sensed by each sensing unit in real time; and determining the sub-screen with small state change as a target screen according to the initial state parameter and the final state parameter of each sub-screen, controlling the flexible display screen 30 to switch the target screen, and controlling the target screen to display content.
Specifically, the processor 10 acquires the initial state parameters of the first screen 31 sensed by the first sensing unit 40 in real time and the initial state parameters of the second screen 33 sensed by the second sensing unit 50 in real time when the bending angle between the first screen 31 and the second screen 33 starts to change and the screen folding state at the bending line is switched from the unfolded state to the bent state. The processor 10 also acquires the final state parameter of the first screen 31 sensed by the first sensing unit 40 in real time and the final state parameter of the second screen 33 sensed by the second sensing unit 50 in real time when the bending angle between the first screen 31 and the second screen 33 stops changing.
It should be noted that the initial state parameter and the final state parameter mentioned above include at least one of the following parameters: acceleration of gravity, direction, degree of obstruction.
The processor 10 determines a screen with a small change in state as a target screen based on the initial state parameter and the final state parameter of the first screen 31 and the initial state parameter and the final state parameter of the second screen 33. It is understood that the target screen may be one of the first screen 31 and the second screen 33; in the embodiment where the second screen 33 is multiple, the target screen may also be one or more sub-screens of the multiple second screens 33, or the first screen 31 and one or more sub-screens of the multiple second screens 33. The processor 10 also controls the target screen display content.
Thus, the sub-screen with a small change in state is determined as the target screen from the initial state parameter and the final state parameter of the first screen 31 and the initial state parameter and the final state parameter of the second screen 33, and the target screen is controlled to display the contents. Therefore, the screen can be switched according to the change of the screen state, and more interesting and convenient interactive experience is brought to the user; the screen switching can be dynamically realized without manual operation, and in the state that the screen is not bent, the first sensing unit 40 and the second sensing unit 50 do not need to sense the screen state, so that the screen switching device is convenient for users and saves energy consumption.
Specifically, the processor 10 calculates a first difference between an initial state parameter and a final state parameter of the first screen 31, calculates a second difference between the initial state parameter and the final state parameter of the second screen 33, further determines the first screen 31 or the second screen 33 corresponding to the smaller difference as a target screen according to the first difference and the second difference, and controls the target screen to display content.
Accordingly, the processor 10 can determine the state changes of the first screen 31 and the second screen 33 according to the first difference value representing the state change of the first screen 31 and the second difference value representing the state change of the second screen 33, determine the screen with the small state change as the target screen, and control the display content of the target screen, thereby performing the screen switching according to the small state change of the screen, being more consistent with the use behavior of the user, being capable of understanding the requirements of the user, and having a good user experience.
In another embodiment, a threshold value X is set for the first difference value and the second difference value mentioned above, and when both the first difference value and the second difference value are smaller than the threshold value X, the processor 10 controls not to adjust the state of the first screen 31 and/or the second screen 33. In particular, in practical applications, a user often performs fine adjustment on the bending angle of the first screen 31 and/or the second screen 33 for a comfortable hand feeling during the operation of the mobile terminal 100, in this case, the user does not aim to adjust the screen of the mobile terminal 100 but only aims to hold the mobile terminal 100 more comfortably, and therefore, when the first difference and the second difference are detected to be smaller than the threshold X, the target screen is not determined, and the control switching screen is not displayed. That is, when the flexible display screen 30 is in the bent state before and after bending, the processor 10 controls the flexible display screen 30 not to perform screen switching.
Referring to fig. 2 again, the display surfaces of the first screen 31 and the second screen 33 are facing upwards, and the first screen 31 and the second screen 33 are located in the same horizontal plane, that is, the first screen 31 and the second screen 33 are in the unfolded state, and therefore, the first screen 31 and the second screen 33 have substantially the same state, and therefore, the first screen 31 and the second screen 33 can be in the lighting state at the same time.
Referring to fig. 3, the second screen 33 is bent downward from the bending line EF, such that the second screen 33 is bent relative to the first screen 31 and located right below the first screen 31, in other words, the second screen 33 rotates clockwise 180 degrees along the bending line EF with the Y-axis as the viewing direction. In the process of bending the second screen 33, the display surface of the second screen 33 is turned from the upward direction to the downward direction, and the state of the second screen 33 is greatly changed compared with the state before bending, however, in the process, the display surface of the first screen 31 is always upward, and the state of the first screen 31 and the state before bending are basically unchanged. Accordingly, the first screen 31 is determined as a target screen, and the switching of the display with the first screen 31 is controlled, and the second screen 33 is closed. That is, when the flexible display 30 is switched from the unfolded state to the folded state, the processor 10 determines a target screen and controls the flexible display 30 to switch the target screen.
The second screen 33 is restored from the state shown in fig. 3 to the state shown in fig. 2, that is, the second screen 33 rotates 180 degrees counterclockwise along the bending line EF with the Y axis as the viewing direction, so that the second screen 33 gradually rotates to the plane where the first screen 31 is located until the second screen 33 and the first screen 31 are located in the same plane and the display surface of the second screen 33 faces upward, and the first screen 31 and the second screen 33 are controlled to be simultaneously lighted. That is, when the flexible display 30 is in the unfolded state or switched from the folded state to the unfolded state, the processor 10 controls all of the at least two screens to be lit.
In one embodiment, when the target screen is changed, the size of the display content of the mobile terminal 100 is adaptively displayed in all the lighted screens. For example, the mobile terminal 100 includes a first screen 31 and a second screen 33, and the initial state is that both screens are unfolded to face the same plane and are both lighted, when the display contents are displayed in the total screen composed of both screens; when the first screen 31 is determined as the target screen, the second screen 33 is controlled to be closed, and the display content is dynamically reduced to an appropriate scale and displayed in the first screen 31; similarly, when the second screen 33 is also confirmed as the target screen and is lighted, the display content is enlarged to an appropriate scale and displayed in the total screen composed of the two screens.
Specifically, the initial state parameters of the first screen 31 include an initial gravitational acceleration and an initial direction, and the final state parameters include a final gravitational acceleration and a final direction. That is, the first sensing unit 40 senses an initial gravitational acceleration and an initial direction of the first screen 31, and also senses a final gravitational acceleration and a final direction of the first screen 31. The processor 10 calculates a gravitational acceleration difference between the initial gravitational acceleration and the final gravitational acceleration of the first screen 31, and calculates a direction difference between the initial direction and the final direction. That is, the first difference value includes a gravity acceleration difference value and a direction difference value of the first screen 31.
Specifically, the initial state parameters of the second screen 33 include an initial gravitational acceleration and an initial direction, and the final state parameters include a final gravitational acceleration and a final direction. That is, the second sensing unit 50 senses the initial gravitational acceleration and the initial direction of the second screen 33, and also senses the final gravitational acceleration and the final direction of the second screen 33. The processor 10 calculates a gravitational acceleration difference between the initial gravitational acceleration and the final gravitational acceleration of the second screen 33, and calculates a direction difference between the initial direction and the final direction. That is, the second difference value includes the gravity acceleration difference value and the direction difference value of the second screen 33.
Further, the difference between the initial state parameter and the final state parameter is positively correlated with the absolute value of the difference between the initial gravitational acceleration and the final gravitational acceleration, and/or with the absolute value of the difference between the initial direction and the final direction.
The processor 10 compares the gravity acceleration difference and the direction difference of the first screen 31 with the gravity acceleration difference and the direction difference of the second screen 33, respectively, or performs weight distribution on the respective gravity acceleration difference and the direction difference, calculates a comprehensive difference representing the state change of the screen, and determines the sub-screen with small state change as the target screen according to the comprehensive difference.
Specifically, referring to fig. 1 again, the first sensing unit 40 includes a first gravitational acceleration sensor 41 and a first direction sensor 42 disposed on the first screen 31. The first gravitational acceleration sensor 41 senses gravitational acceleration of the first screen 31. The first direction sensor 42 senses the direction of the first screen 31. The second sensing unit 50 is disposed on the second screen 33 at a second gravity acceleration sensor 51 and a second direction sensor 52. The second gravitational acceleration sensor 51 senses gravitational acceleration of the second screen 33. The second direction sensor 52 senses the direction of the second screen 33.
Specifically, the first gravitational acceleration sensor 41 can sense the change of the acceleration force of the first screen 31, where the acceleration force is the force acting on the first screen 31 during the acceleration process of the first screen 31, and various movement changes such as shaking, falling, rising, and falling can be converted into an electrical signal by the first gravitational acceleration sensor 41, and then the gravitational acceleration value of the first screen 31 is obtained after calculation and analysis by the processor 10. Alternatively, the first gravitational acceleration sensor 41 is a three-axis gravitational acceleration sensor. The first gravitational acceleration sensor 41 is capable of sensing the gravitational acceleration of the first screen 31 on three axes X, Y, Z. The first direction sensor 42 can sense a direction of the first screen 31, which is a usage direction of the first screen 31 and at least includes a right vertical direction, an inverted vertical direction, a left horizontal direction, a right horizontal direction, a pitch direction, and a pitch direction.
Specifically, the second gravity acceleration sensor 51 can sense a change of an acceleration force, where the acceleration force is a force acting on the second screen 33 during acceleration of the second screen 33, and various movement changes such as shaking, falling, rising, and falling can be converted into an electrical signal by the second gravity acceleration sensor 51, and then the gravity acceleration value of the second screen 33 is obtained through calculation and analysis by the processor 10. Alternatively, the second gravitational acceleration sensor 51 is a three-axis gravitational acceleration sensor. The second gravitational acceleration sensor 51 can sense the gravitational acceleration of the second screen 33 on three axes X, Y, Z. The second direction sensor 52 can sense the direction of the second screen 33, which is the direction of the first screen 31, and includes at least a right vertical direction, an inverted vertical direction, a left horizontal direction, a right horizontal direction, a pitch direction, and a pitch direction.
The present application can determine the target screen in combination with the respective gravitational acceleration values and the use directions of the first screen 31 and the second screen 33, and control the target screen to display the content.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a mobile terminal 100a according to another embodiment of the present application. Among them, the flexible display 30 includes a first screen 31 and two second screens 33. The two second screens 33 are located at two sides of the first screen 31, and the second screen 33, the first screen 31 and the second screen 33 are formed by bending a large screen along two corresponding bending lines.
It is understood that other components of the mobile terminal 100, 100a, such as the front case, the middle frame, the rear case, the circuit board, etc., may be bent at the bending line, and may be bent at a position corresponding to the bending line along with the bending of the flexible display 30, so that the mobile terminal 100 may be bent.
Optionally, in an embodiment, the mobile terminal 100 further includes a face recognition camera 70. When the processor 10 determines that the bending angle of the flexible display screen is changed according to the bending angle of the flexible display screen 30 sensed by the screen bending sensor 60, the processor controls the face recognition camera 70 to be turned on and to recognize a partial screen facing the face of the user, and determines the partial screen as the target screen, and controls the target screen to display content.
Further, when it is determined that the bending angle of the flexible display screen 30 changes and the folding state of the screen changes, the processor 10 controls to determine the partial screen facing the face of the user, which is opened and recognized by the face recognition camera 70, as the target screen, and controls the target screen to display the content.
Therefore, when the processor 10 determines that the bending angle of the flexible display screen 30 changes and the folding state of the screen changes, the face recognition camera 70 is controlled to be turned on and recognize the partial screen facing the face of the user as the target screen, and in other cases, the face recognition camera 70 is controlled to be turned off. Thus, energy consumption can be reduced.
