Patent Description:
With the development of science and technologies and the progress of the times, more and more mobile phone manufacturers are in pursuit of mobile phones with larger screen-to-body ratios, to better meet the needs of consumers.

To increase screen-to-body ratios, many mobile phone manufacturers use bang screens or water drop screens (a drop-shaped "little bang" reserved at the top of a screen and user for disposing of a camera). However, due to the existence of a front-facing camera, a bang screen or a water drop screen is not a real full screen, and its relatively low screen-to-body ratio still affects its display effect. <CIT> discloses an electronic apparatus. The electronic apparatus comprises a camera, a first display screen, and a second display screen, wherein the camera is disposed on one side of the first display screen, and the first display screen has a transparent area corresponding to the camera; and the second display screen and the first display screen are arranged in a laminating manner, the second display screen can move between a first position and a second position, when the second display screen is disposed on the first position, the second display screen is disposed between the first display screen and the camera and is opposite to the transparent area, and when the second display screen is disposed on the second position, the second display screen is deviated from the transparent area. <CIT> discloses an electronic device, comprising a camera and a display screen, wherein the display screen comprises a first display screen and a second display screen, which are arranged side by side in a length direction or a width direction thereof; the display screen can be switched between a first state and a second state; when the display screen is in the first state, the first display screen and the second display screen are spliced to form a display area of the electronic device; the camera is located on one side of the display screen, and the display screen blocks the camera; when the display screen is in the second state, the first display screen is spaced apart from the second display screen to allow the camera to receive light from the other side of the display screen through a gap between the first display screen and the second display screen. <CIT> discloses a display device. The display device comprises a device main body, and a first display screen and a second display screen, which cover one side face of the device main body together, wherein the device main body comprises a first area used for setting the first display screen and a second area used for setting the second display screen, and the second area is provided with at least one functional module and at least one group of sliding mechanisms for the sliding of the second display screen; and the second display screen can slide along the device main body through the at least one group of sliding mechanisms so as to expose or cover the at least one functional module. <CIT> discloses electronic equipment. The electronic equipment comprises a camera and a display screen, wherein the display screen can be switched between a first state and a second state, the display screen comprises a first display screen, and a second display screen which is movable relative to the first display screen; when the display screen is in the state, the camera is located at one side of the display screen, and the display screen shields the camera; when the display screen is located at the second state, at least partial structure of the display screen is not opposite to the camera, the camera is suitable for receiving the light from the other side of the display screen.

Embodiments of the present disclosure provide a screen control method, a terminal, and a storage medium, to resolve a problem that screen display effects are impacted due to small screen-to-body ratios.

According to a first aspect, a terminal is provided, where the terminal includes a screen, a camera, and a processor, the screen includes a movable first sub-screen, and the camera is located below the first sub-screen; and.

According to a second aspect, a screen control method applied to the terminal according to the foregoing embodiment is provided, where the terminal includes a screen and a camera, the screen includes a movable first sub-screen, the camera is located below the first sub-screen, and the method includes:.

In the embodiments of the present disclosure, the camera is disposed below the movable first sub-screen of the terminal so that a bang or water drop area for disposing of the camera does not need to be reserved. In this way, the display area of the screen is greatly enlarged. Therefore, the screen-to-body ratio of the terminal is further increased. In addition, according to the under-screen camera solution provided in the embodiments of the present disclosure, the camera can be switched between the states only by controlling the movement of the first sub-screen. Therefore, the operation is convenient and fast, and the design complexity is relatively low.

The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure.

The following describes the technical solutions in various embodiments of the present disclosure in detail with reference to the accompanying drawings.

In this specification, it should be learned that "movable screen part" and "first sub-screen" are interchangeable and mean the same thing. In addition, "non-movable screen part" and "second sub-screen" are interchangeable and mean the same thing.

<FIG> is a flowchart of a screen control method according to an embodiment of the present disclosure. Referring to <FIG>, the screen control method provided in this embodiment of the present disclosure may be executed by a processor in a terminal. The terminal includes a screen (that is, a display screen) and a camera (for example, a front-facing camera), where the screen includes a movable first sub-screen (that is, a movable screen part ), the camera may be located below the first sub-screen, and the method may include:.

Step <NUM>. Receive a first instruction for enabling the camera.

In this embodiment of the present disclosure, the terminal may be an electronic device such as a mobile phone or a tablet computer.

The terminal may include a mainboard. The screen and the camera may be connected to the mainboard. The processor may be disposed on the mainboard. Step <NUM> as well as Step <NUM> to Step <NUM> may be executed by the processor in the terminal.

In this embodiment of the present disclosure, the first instruction for enabling the camera may be triggered by such an operation that a user clicks an installed camera application or presses a shortcut key used for enabling the camera. Once the user enables the installed camera application or presses the shortcut key used for enabling the camera, the terminal can obtain the first instruction for enabling the camera.

Step <NUM>. Control the first sub-screen to move so that the camera changes from a first state to a second state.

When the camera (for example, the front-facing camera) in the terminal is triggered (for example, triggered by such an operation that the user clicks the installed camera application or presses the shortcut key) for enabling, the processor in the terminal can learn that the camera needs to be enabled, and controls the movable screen part to move so that the camera changes from being covered or sheltered by the first sub-screen (that is, the movable screen part ) to not being covered by the first sub-screen (the movable screen part).

In this embodiment of the present disclosure, when the terminal is in a screen-off state, the camera is in a state of being covered by the screen (that is, the movable first sub-screen) by default. When the terminal is switched from the screen-off state to a screen-on state, the camera can also be in the state of being covered by the screen (that is, movable first sub-screen) by default, provided that the camera is not enabled. In this case, the entire screen can be normally used for displaying. Once the camera is triggered for enabling, Step <NUM> may be performed to control the first sub-screen to move so that the camera changes from the first state to the second state.

When in the first state, the camera is covered by the first sub-screen, and when in the second state, the camera is exposed out of the first sub-screen. When in the second state, the camera can be enabled normally and can collect images. Quality of the images collected by the camera in the second state is relatively high because the camera is not covered by the first sub-screen.

Step <NUM>. Receive a second instruction for disabling the camera.

In this embodiment of the present disclosure, when receiving the second instruction for exiting the camera from the user (for example, the user presses a return key or a homepage key), the terminal may disable (stop enabling) the camera.

Step <NUM>. Control the first sub-screen to move so that the camera changes from the second state to the first state.

When the terminal disables (stops enabling) the camera, the processor may control the first sub-screen (the movable screen part) to move so that the camera changes from not being covered by the first sub-screen to being covered by the first sub-screen, that is, returns to the initial state.

In this embodiment of the present disclosure, the camera is disposed below the movable first sub-screen (that is, the movable screen part) of the terminal so that a bang or water drop area for disposing of the camera does not need to be reserved. In this way, the display area of the screen is greatly enlarged. Therefore, the screen-to-body ratio of the terminal is further increased. In addition, according to the under-screen camera solution provided in the embodiments of the present disclosure, the camera can be switched between the states only by controlling the movement of the first sub-screen. Therefore, the operation is convenient and fast, and the design complexity is relatively low.

In this embodiment of the present disclosure, the first sub-screen (the movable screen part) can be controlled to move in various manners so that the camera changes from the first state (being covered by the movable screen part) to the second state (that is, not being covered by the movable screen part) or from the second state (that is, not being covered by the movable screen part) to the first state (that is, being covered by the movable screen part).

For example, if the screen of the terminal is a flexible screen, the camera can be disposed on one side of the screen, for example, at the top or bottom of the screen, on the left or right side of the screen, or the like (the top, bottom, left site, right side herein are orientations described when the user faces the front side of the screen of the terminal). In this way, when the terminal is in the screen-off state, the camera can be in the state of being covered by the movable screen part by default. When the terminal is switched from the screen-off state to the screen-on state, the camera can also be in the state of being covered by the movable screen part of the flexible screen by default, provided that the camera is not enabled. In this case, the entire flexible screen can be fully utilized for displaying. Once the camera is triggered for enabling, the processor can control the movable screen part to bend or fold so that the camera changes from the first state (being covered by the movable screen part) to the second state (not being covered by the movable screen part). Herein, when the camera is disposed at the top or bottom or on the left or right side of the screen of the terminal, the movable screen part can bend or fold. Therefore, the camera is exposed and is not covered by the movable screen part any more.

Correspondingly, after the camera is used, or when enabling the camera needs to be stopped or disabling the camera is required, the movable screen part can be controlled to extend so that the camera changes from not being covered by the movable screen part to being covered by the movable screen part.

In this embodiment of the present disclosure, movement of the movable screen part may be realized under the action of a movable supporting component, and movement of the supporting component may be controlled by the processor.

<FIG> is a schematic diagram of state changes of a flexible screen. Referring to <FIG>, a camera <NUM> is disposed at the top of a terminal. When in an initial state, a movable screen part may be located at a position <NUM> where the camera <NUM> is covered. In this case, if the camera is not enabled, the entire flexible screen can display normally. When the camera is enabled, the movable screen part may be controlled to bend or fold to a position <NUM> where the camera <NUM> is not covered. In this case, the camera can be used normally. When enabling the camera is stopped, the movable screen part may be controlled to restore to the initial state, that is, move back from the position <NUM> to the position <NUM> where the camera <NUM> is covered. After the flexible screen returns to the position <NUM>, the entire flexible screen can still be used normally for displaying in a screen-on state. In this way, before the camera is enabled, the screen can be fully utilized for displaying, thereby optimizing the display effect.

In addition, in this embodiment of the present disclosure, a front-facing camera is hidden under the movable screen part. Before the front-facing camera is enabled, the movable screen part is in an extended state. After the front-facing camera is enabled, the under-screen camera can be exposed by bending or folding a small part (that is, the movable screen part) of the flexible screen so that the under-screen camera can be used to collect images. After the front-facing camera is disabled, the first sub-screen that is in a bent or folded state can be restored to the extended state. This manner of controlling the flexible screen to move is simple to operate, and does not need excessive mobile phone components. Therefore, components of a mobile phone can be kept simple and integrated while a full-screen effect is achieved.

For another example, the screen of the terminal is a common screen. In this embodiment of the present disclosure, the screen can be divided into two parts that can be separated from each other. One part (that is, the first sub-screen) is controlled to move so that the camera changes from the first state (being covered by the movable screen part) to the second state (that is, not being covered by the movable screen part) or from the second state (that is, not being covered by the movable screen part) to the first state (that is, being covered by the movable screen part). In this case, besides the movable first sub-screen, the screen of the terminal may further include a fixed second sub-screen. The first sub-screen and the second sub-screen are disposed independently. When the camera is completely covered by the first sub-screen, the first sub-screen and the second sub-screen form a complete screen. The first sub-screen can be in various shapes. For example, it can be circular, rectangular, or rhombic. The camera can be initially covered by the first sub-screen. Specifically, when the terminal is in a screen-off state, the camera can be in the state of being covered by the first sub-screen by default. When the terminal is switched from the screen-off state to the screen-on state, the camera can also be in the state of being covered by the first sub-screen by default, provided that the camera is not enabled. In this case, the entire flexible screen can be fully utilized for displaying. Once the camera is triggered for enabling, a processor can control the first sub-screen to descend to a position below the inner surface of the second sub-screen, and control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state. Herein, it should be learned that, before the camera is enabled, the first sub-screen may be in a state of being aligned with the second sub-screen, and the two sub-screens form a complete display screen.

Correspondingly, after the camera is used, or when enabling the camera needs to be stopped, the processor can control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state. Then, the processor can control the first sub-screen to ascend to a position aligned with the second sub-screen. In this way, a complete display screen is formed.

This manner of switching the camera between the states via ascending, descending, and moving is simple to operate. The switching from the first state to the second state can be fast only by descending and moving the first sub-screen. The switching from the second state to the first state can be fast only by moving and ascending the first sub-screen. In addition, before the camera is enabled, the screen can be fully utilized for displaying, thereby optimizing the display effect.

In this embodiment of the present disclosure, the first sub-screen can be descended or ascended in various manners. For example, the terminal may include a driving device, and the processor can control the driving device to descend or ascend the first sub-screen and to drive the first sub-screen to perform various types of movement after the first sub-screen descends to the position below the inner surface of the second sub-screen. Herein, it should be learned that, "the inner surface of the second sub-screen" mentioned in this embodiment of the present disclosure indicates a surface, facing (near) the camera, of the second sub-screen. The outer surface of the second sub-screen is a surface, facing (near) a user, of the second sub-screen.

For another example, the first sub-screen can be disposed on a compressible component, where the compressible component is made of a compressible material and thicker than the second sub-screen. In this way, disposing the first sub-screen on the compressible component can prevent the first sub-screen from being damaged due to a direct movement of the first sub-screen. In addition, as the compressible component is thicker than the second sub-screen, it can be ensured that the first sub-screen can be located below the inner surface of the second sub-screen by adjusting the thickness of the compressible component.

In this embodiment of the present disclosure, the compressible component may be an elastic component (for example, a spring), an inflatable component, piezoelectric ceramics, or the like. Therefore, ascending and descending of the first sub-screen can be realized by adjusting the height of the compressible component. Correspondingly, the controlling the first sub-screen to descend to a position below the inner surface of the second sub-screen may include: controlling the compressible component to be compressed by a preset height so that the first sub-screen descends to the position below the inner surface of the second sub-screen; and the controlling the first sub-screen to ascend to a position aligned with the second sub-screen may include: controlling the compressible component to be decompressed by the preset height so that the first sub-screen ascends to the position aligned with the second sub-screen. In this way, the ascending and descending of the first sub-screen can be realized conveniently and fast by adjusting the height of the compressible component.

Specifically, when the compressible component is an elastic component, the thickness of the compressible component can be adjusted by adjusting elastic deformation; or when the compressible component is piezoelectric ceramics, its thickness can be adjusted by controlling a voltage provided for the piezoelectric ceramics. In an embodiment of the present disclosure, the controlling the first sub-screen to descend to a position below the inner surface of the second sub-screen may specifically be: reducing the thickness of the compressible component by controlling a voltage provided for the compressible component so that the first sub-screen is controlled to descend to the position below the inner surface of the second sub-screen. Correspondingly, the controlling the first sub-screen to ascend to a position aligned with the second sub-screen may specifically be: increasing the thickness of the compressible component by controlling the voltage provided for the compressible component so that the first sub-screen is controlled to ascend to be aligned with the second sub-screen. Due to this manner of controlling the thickness of the compressible component based on the voltage, the thickness of the compressible component can be controlled precisely.

It should be learned that, in other examples that do not fall within the scope of the appended claims, the compressible component may not be disposed, and the driving device is directly coupled with the first sub-screen and directly drives, under the control of the processor, the first sub-screen to perform movement (including descending, movement below the inner surface of the second sub-screen after the descending, and subsequent ascending), thereby reducing under-screen components. However, when the terminal includes the compressible component, and the first sub-screen is disposed on the compressible component, the driving device can be coupled with the compressible component and drive the compressible component under the control of the processor, so that the first sub-screen is driven to perform movement (including descending, movement below the inner surface of the second sub-screen after the descending, and subsequent ascending). In this way, damage to the first sub-screen can be avoided, and the movement of the first sub-screen can be controlled more conveniently, fast, and precisely.

In this embodiment of the present disclosure, the controlling the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state may include: controlling the first sub-screen to move linearly below the inner surface of the second sub-screen in a first movement direction so that the camera changes from the first state to the second state. Correspondingly, the controlling the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state may include: controlling the first sub-screen to move linearly below the inner surface of the second sub-screen in a second movement direction so that the camera changes from the second state to the first state, where the second movement direction is opposite to the first movement direction. Specifically, after the first sub-screen is driven to move to the position below the inner surface of the second sub-screen, the processor can control the first sub-screen to move linearly below the inner surface of the second sub-screen in the first movement direction so that the camera changes from the first state to the second state. When the movement of the first sub-screen is complete and the first sub-screen needs to return to an initial position, for example, after the camera is used, the processor can control the first sub-screen to move linearly below the inner surface of the second sub-screen in the second movement direction so that the camera changes from the second state to the first state, where the second movement direction is opposite to the first movement direction. For example, referring to <FIG> is a schematic diagram of a first sub-screen that is rectangular and that moves linearly in a first direction, and <FIG> is a schematic diagram of a first sub-screen that is circular and that moves linearly in the first direction. As shown in <FIG>, if the first sub-screen <NUM> descends to a position below an inner surface of a second sub-screen <NUM>, for example, descends linearly, after an under-screen camera <NUM> is used, the first sub-screen <NUM> can be controlled to ascend linearly in the original direction and further return to the position before the descending. Therefore, the first sub-screen can ascend from the position below the inner surface of the second sub-screen and further return to the position aligned with the second sub-screen. Therefore, a complete screen is formed again. In this way, the first sub-screen can apply to the linear movement scenario where it returns to the position before the descending via the linear movement, which enriches movement scenarios of the first sub-screen, and ensures that implementations are flexible and diversified.

In this embodiment of the present disclosure, the controlling the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state may include: controlling the first sub-screen to rotate below the inner surface of the second sub-screen in a first rotational direction so that the camera changes from the first state to the second state. Correspondingly, the controlling the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state may include: controlling the first sub-screen to rotate below the inner surface of the second sub-screen in a second rotational direction so that the camera changes from the second state to the first state, where the second rotational direction is opposite to the first rotational direction. Specifically, after the first sub-screen is driven to move to the position below the inner surface of the second sub-screen, the processor can control the first sub-screen to rotate below the inner surface of the second sub-screen in the first rotational direction so that the camera changes from the first state to the second state. When the movement of the first sub-screen is complete and the first sub-screen needs to return to an initial position, for example, after the camera is used, the processor can control the first sub-screen to rotate below the inner surface of the second sub-screen in the second rotational direction so that the camera changes from the second state to the first state, where the second rotational direction is opposite to the first rotational direction. For example, referring to <FIG> is a schematic diagram of a first sub-screen that is rectangular and that rotates in a first rotational direction, and <FIG> is a schematic diagram of a first sub-screen that is circular and that rotates in the first rotational direction. As shown in <FIG>, if the first sub-screen <NUM> descends to a position below an inner surface of a second sub-screen <NUM>, for example, rotates in an anti-clockwise direction (for example, rotating <NUM>°), after an under-screen camera <NUM> is used, the first sub-screen <NUM> can be controlled to rotate in a clockwise direction for the same angle (for example, rotating <NUM>°) and further return to the position before the descending. Therefore, the first sub-screen can ascend from the position below the inner surface of the second sub-screen and further return to the position aligned with the second sub-screen. Therefore, a complete screen is formed again. In this way, the first sub-screen can apply to the rotational movement scenario where it returns to the position before the descending via the rotational movement, which enriches movement scenarios of the first sub-screen, and ensures that implementations are flexible and diversified.

<FIG> is a structural block diagram of a terminal according to an embodiment of the present disclosure, where the terminal may be an electronic device such as a mobile phone or a tablet computer. Referring to <FIG>, the terminal provided in this embodiment of the present disclosure may include a screen <NUM>, a middle frame <NUM>, a camera <NUM> and a processor <NUM>. The camera <NUM> may be coupled with the middle frame <NUM>, the screen includes a first sub-screen (that is, a movable screen part), and the camera <NUM> may be located below the first sub-screen.

The processor <NUM> may be configured to: when receiving a first instruction for enabling the camera, control the first sub-screen to move so that the camera changes from a first state to a second state; and when receiving a second instruction for disabling the camera, control the first sub-screen to move so that the camera changes from the second state to the first state, where when in the first state, the camera is covered by the first sub-screen, and when in the second state, the camera is exposed out of the first sub-screen.

The terminal may further include a mainboard (not shown in the figure). The mainboard may be disposed in the middle frame <NUM>. The processor <NUM> may be disposed on the mainboard. The camera <NUM> may be connected to the mainboard.

In this embodiment of the present disclosure, the camera is disposed below the movable screen part of the terminal so that a bang or water drop area for disposing of the camera does not need to be reserved. In this way, the display area of the screen is greatly enlarged. Therefore, the screen-to-body ratio of the terminal is further increased. In addition, according to the under-screen camera solution provided in the embodiments of the present disclosure, the camera can be switched between the states only by controlling the movement of the first sub-screen. Therefore, the operation is convenient and fast, and the design complexity is relatively low.

Optionally, in an embodiment of the present disclosure, as shown in <FIG>, the screen is a flexible screen, and the camera is disposed on one side of the screen. When controlling the first sub-screen to move so that the camera changes from the first state to the second state, the processor <NUM> may be specifically configured to: control the first sub-screen to be in a bent state or a folded state so that the camera changes from the first state to the second state. When controlling the first sub-screen to move so that the camera changes from the second state to the first state, the processor <NUM> may be specifically configured to: control the first sub-screen to change from the bent state or the folded state to an extended state so that the camera changes from the second state to the first state.

In this embodiment of the present disclosure, a front-facing camera is hidden under the movable screen part. Before the front-facing camera is enabled, the movable screen part is in an extended state. After the front-facing camera is enabled, the under-screen camera can be exposed by bending or folding a small part (that is, the movable screen part) of the flexible screen so that the under-screen camera can be used to collect images. After the front-facing camera is disabled, the first sub-screen that is in a bent or folded state can be restored to the extended state. This manner of controlling the flexible screen to move is simple to operate, and does not need excessive mobile phone components. Therefore, components of a mobile phone can be kept simple and integrated while a full-screen effect is achieved. In addition, according to the manner of controlling the flexible screen, before the camera is enabled, the screen can be fully utilized for displaying, thereby optimizing the display effect.

Optionally, in an embodiment of the present disclosure, as shown in <FIG>, the screen further includes a fixed second sub-screen, the first sub-screen and the second sub-screen are disposed independently, and when the camera is completely covered by the first sub-screen, the first sub-screen and the second sub-screen form a complete screen. When controlling the first sub-screen to move so that the camera changes from the first state to the second state, the processor <NUM> may be specifically configured to: control the first sub-screen to descend to a position below the inner surface of the second sub-screen, and control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state. When controlling the first sub-screen to move so that the camera changes from the second state to the first state, the processor <NUM> may be specifically configured to: control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state, and after the camera changes from the second state to the first state, control the first sub-screen to ascend to a position aligned with the second sub-screen. This manner of switching the camera between the states via ascending, descending, and moving is simple to operate. The switching from the first state to the second state can be fast only by descending and moving the first sub-screen. The switching from the second state to the first state can be fast only by moving and ascending the first sub-screen. In addition, before the camera is enabled, the screen can be fully utilized for displaying, thereby optimizing the display effect.

In an embodiment of the present disclosure, the terminal further includes a compressible component, where the first sub-screen is disposed on the compressible component, and the compressible component is made of a compressible material and thicker than the second sub-screen. In this way, disposing the first sub-screen on the compressible component can prevent the first sub-screen from being damaged due to a direct movement of the first sub-screen. In addition, as the compressible component is thicker than the second sub-screen, it can be ensured that the first sub-screen can be located below the inner surface of the second sub-screen by adjusting the thickness of the compressible component.

In an embodiment of the present disclosure, when controlling the first sub-screen to descend to the position below the inner surface of the second sub-screen, the processor <NUM> is specifically configured to: control the compressible component to be compressed by a preset height so that the first sub-screen descends to the position below the inner surface of the second sub-screen. When controlling the first sub-screen to ascend to the position aligned with the second sub-screen, the processor <NUM> may be specifically configured to: control the compressible component to be decompressed by the preset height so that the first sub-screen ascends to the position aligned with the second sub-screen. In this way, the ascending and descending of the first sub-screen can be realized conveniently and fast by adjusting the height of the compressible component.

Optionally, in an embodiment of the present disclosure, the compressible component is connected to a power supply circuit. When controlling the first sub-screen to descend to the position below the inner surface of the second sub-screen, the processor <NUM> may be specifically configured to: reduce the thickness of the compressible component by controlling a voltage provided for the compressible component so that the first sub-screen is controlled to descend to the position below the inner surface of the second sub-screen. When controlling the first sub-screen to ascend to the position aligned with the second sub-screen, the processor <NUM> may be specifically configured to: increase the thickness of the compressible component by controlling the voltage provided for the compressible component so that the first sub-screen is controlled to ascend to be aligned with the second sub-screen. Due to this manner of controlling the thickness of the compressible component based on the voltage, the thickness of the compressible component can be controlled precisely.

Optionally, in an embodiment of the present disclosure, the terminal may further include a driving device, where the driving device is coupled with the first sub-screen and is configured to: under the control of the processor, drive the first sub-screen to move. In this embodiment of the present disclosure, when the driving device directly drives the first sub-screen to move, under-screen components can be reduced.

Optionally, in an embodiment of the present disclosure, the terminal may further include a driving device, where the driving device is coupled with the compressible component and is configured to: under the control of the processor, drive the compressible component to move so that the first sub-screen is driven to move. When the driving device drives the compressible component so that the first sub-screen is driven to move, damage to the first sub-screen can be avoided, and the movement of the first sub-screen can be controlled more conveniently, fast, and precisely.

Optionally, in another embodiment of the present disclosure, the terminal further includes a driving device, where the driving device includes a motor and a shaft, and the motor is fixed on the middle frame and is coupled with the shaft. The terminal further includes a bearing component, where the compressible component is disposed on the bearing component. The bearing component is coupled with the shaft, and can be fixedly connected to a shaft in various manners, such as welding, gluing, or a threaded manner through a hole formed in the bearing shaft. The terminal may further include a camera base, where the camera base is fixed on the middle frame, and the camera is fixed on the camera base. The motor drives the shaft to move when working, movement of the shaft drives the bearing component to move, and the compressible component and the first sub-screen are further driven to move. In this embodiment of the present disclosure, the compressible component is disposed on the bearing component, and is connected to the driving device via the bearing component so that the first sub-screen can be driven conveniently and fast on the premise that the first sub-screen and the compressible component are intact.

Optionally, in an embodiment of the present disclosure, the shaft is a rotating shaft, where the rotating shaft is connected to the motor via a coupling, an opening is formed in the bearing component, the rotating shaft is fixedly connected to the bearing component through the opening, and the movement of the rotating shaft is rotational movement. When the camera changes from the first state to the second state, movement of the first sub-screen below the inner surface of the second sub-screen is rotational movement in a first rotational direction. When the camera changes from the second state to the first state, the movement of the first sub-screen below the inner surface of the second sub-screen is rotational movement in a second rotational direction, and the second rotational direction is opposite to the first rotational direction. According to this embodiment of the present disclosure, through a specific structural design, the rotational movement of the rotating shaft triggered by the motor can be conveniently transferred to the bearing component so that the bearing component is driven to move rotationally. In this way, the rotational movement of the first sub-screen can be realized conveniently.

Herein, it should be learned that, the rotating shaft may be fixedly connected to the bearing component through the opening in various manners: threaded connection through the opening, interference fit, or the like. In addition, a reinforcing hole may also be formed in the bearing component (for example, in a side surface thereof). A screw can reinforce the connection between the rotating shaft and the bearing component through the reinforcing hole.

Optionally, in an embodiment of the present disclosure, the shaft is a rotary screw rod, where the rotary screw rod is connected to the motor via a coupling, and a screw nut is disposed on the rotary screw rod and fixedly connected to the bearing component. A guide rail is also disposed on the middle frame. The bearing component is on the guide rail and moves linearly along the guide rail under the action of the driving device. Movement of the rotary screw rod is rotational movement. When the camera changes from the first state to the second state, movement of the first sub-screen below the inner surface of the second sub-screen is linear movement in a first movement direction. When the camera changes from the second state to the first state, the movement of the first sub-screen below the inner surface of the second sub-screen is linear movement in a second movement direction, and the second movement direction is opposite to the first movement direction. According to this embodiment of the present disclosure, through a specific structural design, the rotational movement of the rotary screw rod triggered by the motor can be converted to linear movement of the screw nut so that the bearing component is driven to move linearly along the guide rail. In this way, the linear movement of the first sub-screen can be realized conveniently.

The following uses examples in which the first sub-screen performs the linear movement (for example, as shown in <FIG>) and the rotational movement (for example, as shown in <FIG>) after descending to the position below the inner surface of the second sub-screen respectively, to further describe the terminal provided in the embodiments of the present disclosure. It should be learned that, the following description is merely an example embodiment rather than a limitation.

<FIG> is a schematic diagram of a terminal including the first sub-screen according to an embodiment of the present disclosure, where the first sub-screen moves linearly after descending to a height lower than the second sub-screen. <FIG> is an enlarged view of a circled part in <FIG>. <FIG> is an enlarged view of each part in <FIG>.

Before an under-screen camera is enabled, the first sub-screen (that is, a movable screen part) and the second sub-screen (a fixed screen part) are spliced together, and can be fused for displaying via a screen splicing function of software, thereby achieving the display effect of one display screen. The front-facing under-screen camera is disposed below the first sub-screen. While the front-facing under-screen camera is enabled, the first sub-screen moves to a position below the inner surface of the second sub-screen for hiding, as shown in <FIG>. In addition, the screen splicing function can be disabled using the software. In this case, a single screen, namely, the second sub-screen, is used for displaying.

Referring to <FIG>, an implementation for moving the first sub-screen to the position below the inner surface of the second sub-screen may be as follows: The terminal includes a mobile phone middle frame <NUM> and a second sub-screen (a fixed screen) <NUM>. A first sub-screen <NUM> is located at an opening of the second sub-screen <NUM>. An under-screen camera <NUM> is fixed on a camera base <NUM> (for example, using a screw <NUM>). The camera base <NUM> is fixedly connected to the mobile phone middle frame <NUM> (for example, using the screw <NUM>). The under-screen camera <NUM> may be under the opening of the second sub-screen <NUM>. The first sub-screen <NUM> is fixedly connected to a compressible component <NUM> (for example, using glue). The compressible component <NUM> is connected to a bearing component (a moving platform) <NUM> (for example, using glue). Before the compressible component <NUM> is compressed, the first sub-screen <NUM> and the second sub-screen <NUM> are at the same height. The compressible component <NUM> can be compressed in a direction <NUM> shown in the figure via voltage controlling so that the first sub-screen <NUM> descends to a position below the second sub-screen <NUM>. The bearing component <NUM> is located on a guide rail <NUM>. The guide rail <NUM> is fixedly connected to the middle frame <NUM>, for example, the guide rail <NUM> and the mobile phone middle frame <NUM> are integrally formed using a mold. A micro-motor <NUM> is fixedly connected to the mobile phone middle frame <NUM> via a motor base <NUM> (for example, using the screw <NUM>). The micro-motor <NUM> is fixedly connected to a screw rod <NUM> via a coupling <NUM>, and drives the screw rod <NUM> to rotate. When the motor <NUM> drives the screw rod <NUM> to move rotationally, the screw nut <NUM> moves transversally along the screw rod. The transversal movement of the screw nut <NUM> drives the bearing component <NUM> to move linearly. Therefore, under the action of the screw nut <NUM>, the bearing component <NUM> can move transversally in a direction <NUM> shown in the figure so that the first sub-screen <NUM> moves to the position below the second sub-screen <NUM> and the under-screen camera <NUM> is exposed out.

In a single-screen display process, the under-screen camera can be used normally, for example, used for photo shooting or video recording. After the under-screen camera is used, if a user disables the under-screen camera <NUM> by disabling a shooting application, the micro-motor <NUM> is fixedly connected to the screw rod <NUM> via the coupling <NUM> and drives the screw rod <NUM> to rotate; and under the action of the screw nut <NUM>, drives the bearing component <NUM> to move in a direction opposite to the direction <NUM> shown in the figure so that the bearing component <NUM> moves to the original position before descending. Then, the compressible component <NUM> is decompressed in a direction opposite to the direction <NUM> shown in the figure via voltage driving so that the first sub-screen <NUM> (the movable screen part) returns to be at the same height as the second sub-screen <NUM> (the fixed screen part). In this case, the screen splicing function can be enabled using the software so that the two screens are fused for displaying, thereby achieving the display effect of one display screen.

The screen of the terminal (for example, a mobile phone) provided in this embodiment of the present disclosure is obtained by splicing two screen parts: one is fixed, and the other one is movable. In this implementation, a front-facing camera is hidden under the movable screen. When the front-facing camera is not enabled, the two screen parts are fused for displaying via the splicing function. After the under-screen camera is enabled, the movable screen is moved to be hidden under the fixed screen, and the under-screen camera is used for collecting images and works in the single-screen mode. After the under-screen camera is disabled, the movable screen is moved to the original position, and the splicing function is enabled for fused displaying. In this implementation, the under-screen camera structure is realized by moving a small screen (the first sub-screen). Therefore, components of a mobile phone can be kept simple and integrated while a full-screen effect is achieved.

Referring to <FIG>, an implementation for moving the first sub-screen to the position below the inner surface of the second sub-screen may be as follows: The terminal includes a mobile phone middle frame <NUM> and a second sub-screen (a fixed screen) <NUM>. A first sub-screen (a rotatable screen) <NUM> is located at an opening of the second sub-screen <NUM>. An under-screen camera <NUM> is fixed on a camera base <NUM> (for example, using a screw <NUM>). The camera base <NUM> is fixedly connected to the mobile phone middle frame <NUM> (for example, using the screw <NUM>). The under-screen camera <NUM> may be under the opening of the second sub-screen <NUM>. The first sub-screen <NUM> is fixedly connected to a compressible component <NUM> (for example, using glue). The compressible component <NUM> is connected to a bearing component (a moving platform) <NUM> (for example, using glue). Before the compressible component <NUM> is compressed, the first sub-screen <NUM> and the second sub-screen <NUM> are at the same height. The compressible component <NUM> can be compressed in a direction <NUM> shown in the figure via voltage controlling so that the first sub-screen <NUM> descends to a position below the second sub-screen <NUM>. The bearing component <NUM> is connected to a rotating shaft <NUM>, for example, is in interference fit with the rotating shaft <NUM> and fixed via the screw <NUM>. A micro-motor <NUM> is fixedly connected to the mobile phone middle frame <NUM> via a motor base <NUM> (for example, using the screw <NUM>). The micro-motor <NUM> is fixedly connected to the rotating shaft <NUM> via a coupling <NUM>, and drives the rotating shaft <NUM> to rotate. In this way, the bearing component <NUM> is driven to rotate in a direction <NUM> shown in the figure so that the first sub-screen <NUM> rotates to the position below the second sub-screen <NUM> and the under-screen camera <NUM> is exposed out.

In a single-screen display mode, the under-screen camera can be used normally, for example, used for photo shooting or video recording. After the under-screen camera is used, if a user disables the under-screen camera <NUM> by disabling a shooting application, the micro-motor <NUM> is fixedly connected to the rotating shaft <NUM> via the coupling <NUM> and drives the rotating shaft <NUM> to rotate, thereby driving the bearing component <NUM> to rotate in a direction opposite to the direction <NUM> shown in the figure so that the bearing component <NUM> rotates to the original position. Then, the compressible component <NUM> is decompressed in a direction opposite to the direction <NUM> shown in the figure via voltage driving so that the first sub-screen <NUM> returns to be at the same height as the second sub-screen <NUM>. In this case, the screen splicing function can be enabled using the software so that the two screens are fused for displaying, thereby achieving the display effect of one display screen.

The screen of the terminal (for example, a mobile phone) provided in this embodiment of the present disclosure is obtained by splicing two screen parts: one is fixed, and the other one is rotatable. In this implementation, a front-facing camera is hidden under the rotatable screen. When the front-facing camera is not enabled, the two screen parts are fused for displaying via the splicing function. After the under-screen camera is enabled, the rotatable screen is rotated to be hidden under the fixed screen, and the under-screen camera is used for collecting images and works in the single-screen mode. After the under-screen camera is disabled, the rotatable screen is rotated to the original position, and the splicing function is enabled for fused displaying. In this implementation, the under-screen camera solution is realized by moving a small screen (the first sub-screen). Therefore, components of a mobile phone can be kept simple and integrated while a full-screen effect is achieved.
