This application claims the benefit of priority to Chinese Application No. 201910340380.6, filed on Apr. 25, 2019, the contents of all of which are incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates to the field of terminal technologies and in particular to a terminal with a flexible screen.

BACKGROUND

With the development of science and technology, people use more and more types of terminals in their daily life. All these terminals have different appearances and shapes.

In the related art, a terminal (for example, a mobile phone) is generally in the form of a candy bar, a flip type, a folding type, etc. People can use a mobile phone for communication, entertainment, work, etc. For example, they use the terminal to read e-Books, to edit documents, etc.

SUMMARY

In order to solve the problems in the background, the embodiments of the present disclosure provide a terminal with a flexible screen. The technical solutions are as follows.

According a first aspect of the present disclosure, there is provided a terminal with a flexible screen, comprising a first display screen, a second display screen and a screen spreading and housing device. The first display screen and the second display screen are respectively disposed on a front side and a back side of the terminal. The second display screen is a flexible screen. The screen spreading and housing device is configured to house or spread the second display screen through a change of a structural form.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and illustrative only and are not intended to limit the present disclosure.

DETAILED DESCRIPTION

It should also be noted that in some alternative implementations, the functions/acts noted may occur out of the order noted in the figures. For example, two functions or acts shown in succession may in fact be executed concurrently or may sometimes be executed in the reverse order, depending upon the functionality/acts involved.

The solutions provided by the present disclosure can be used in a scenario in which a user uses a terminal in daily life. For ease of understanding, some terms and application scenarios involved in the embodiments of the present disclosure will be briefly introduced below.

A flexible screen refers to a flexible OLED (Organic Light-Emitting Diode) screen.

FIG. 1is a schematic structural diagram of a terminal according to embodiments of the present disclosure. As shown inFIG. 1, the terminal100includes a display screen101. Optionally, the display screen101is a touch screen. A user can touch an application icon displayed in the display screen101to enable the terminal100to display a corresponding interface. For example, the terminal100can display a short message (SMS) interface in the display screen101when the user clicks an SMS icon in the display screen101, and the terminal100can display a video interface in the display screen101when the user clicks a video icon in the display screen101, etc.

In the related art, different applications may have different requirements on the display screen. For example, the display screen of the terminal can meet the demands of the SMS interface when the terminal displays the SMS interface in the display screen; and although the terminal can play videos in the display screen when the terminal displays the video interface in the display screen, if the attributes of the display screen of the terminal fail to meet the demand for video display, the video interface may be relatively blurrier. However, if the size of the display screen101is directly enlarged, on the one hand, a larger-sized screen means higher power consumption, which has a certain influence on the battery durance of the terminal100; and on the other hand, the size of the terminal100needs to be enlarged accordingly when the size of the display screen101is enlarged, and as a result, the portability of the terminal100will be adversely affected.

Optionally, the terminal described above may be a terminal with a display screen, such as a smart phone, a tablet PC, an e-book reader, smart glasses, a smart watch, a moving picture experts group audio layer IV (MP4) player, a notebook computer, a laptop or a desk computer.

In order to solve the above-mentioned problem, the present disclosure provides a terminal with a flexible screen. Referring toFIG. 2which is a schematic structural diagram of a terminal according to embodiments of the present disclosure. As shown inFIG. 2, the terminal200includes a first display screen201, a second display screen202and a screen spreading and housing device203.

Optionally, the supporting component includes plurality of support bars, of which first ends are connected to the second display screen202.

Moving directions of the first ends, connected to the second display screen202, of the support bars are the same as a spreading or housing direction of the second display screen202.

Optionally, the support bars are supported at a periphery of the second display screen202when the supporting component is in the supported status.

Optionally, the support bars form a specified angle with the spreading or housing direction of the second display screen202and are disposed inside the terminal when the supporting component is in the contracted status.

Optionally, the support bars are disposed on the outer side of the second display screen202when the supporting component is in the contracted status.

Alternatively, the support bars are disposed on the inner side of the second display screen202when the supporting component is in the contracted status.

Optionally, the screen spreading and housing device203further includes a servo component, to which second ends of the support bars are connected.

The servo component is configured to drive the second ends of the support bars during a process in which the supporting component changes from the contracted status to the supported status, such that the first ends of the support bars move in the spreading direction of the second display screen202.

The servo component is configured to drive the second ends of the support bars during a process in which the supporting component changes from the supported status to the contracted status, such that the first ends of the support bars move in the housing direction of the second display screen202.

Optionally, the terminal further includes a processor electrically connected to the servo component.

The processor is configured to send a control signal to the servo component when acquiring a control instruction. The control signal is configured to instruct the servo component to drive the second ends of the support bars.

Optionally, the control instruction is an instruction generated when a designated key is triggered. The designated key is a physical key or a virtual key configured to control the second display screen202to be housed or spread.

Alternatively, the control instruction is an instruction generated when a first application is started up.

Alternatively, the control instruction is an instruction generated when the terminal receives a designated operation that is executed in an application interface of a second application.

Optionally, the processor is electrically connected to the second display screen202.

The processor is configured to control the second display screen202to be lit up during a process in which the supporting component changes from the contracted status to the supported status.

Optionally, the processor is configured to control the second display screen202to be off during a process in which the supporting component changes from the supported status to the contracted status.

In summary, the screen spreading and housing device and the second display screen cooperate with each other, such that the terminal can spread the second display screen from the screen spreading and housing device through the screen spreading and housing device. Alternatively, the terminal can house the second display screen into the screen spreading and housing device through the screen spreading and housing device. Thus, the terminal can be switched between the first display screen and the second display screen. Since the flexible screen and the screen spreading and housing device are combined, both of the screen spreading and housing device and the second display screen are housed inside the terminal when the second display screen is in a housed status, which guarantees the portability of the terminal. Moreover, instead of using the second display screen in all scenarios, the first display screen may be used or the second display screen may be spread for use as required. Thus, the power consumption of the display screen is reduced. Further, the battery durance of the terminal is improved.

In a possible implementation mode, the screen spreading and housing device may be connected to and powered by a power supply of the terminal and is disposed inside the terminal. The terminal spreads the second display screen through the screen spreading and housing device, such that the second display screen is displayed on the back side of the terminal. Referring toFIG. 3which is a schematic structural diagram of another terminal according to embodiments of the present disclosure. As shown inFIG. 3, the terminal300includes a first display screen301, a second display screen302and a screen spreading and housing device303.

The first display screen301and the second display screen302are respectively disposed on a front side and a back side of the terminal. The second display screen302is a flexible screen. The screen spreading and housing device303is configured to spread or house the second display screen302through a change of a structural form.

As shown inFIG. 3, the first display screen301is disposed on the front side of the terminal300, and the second display screen302is disposed on the back side of the terminal300. The second display screen302is the flexible screen and can be housed inside the screen spreading and housing device303or spread from the screen spreading and housing device303. Optionally, in practice, when the second display screen302is housed inside the screen spreading and housing device303, it may be that part of the second display screen302is housed inside the screen spreading and housing device303, and the other part is displayed on the back side of the terminal300as shown inFIG. 3. Since the second display screen needs to be housed inside the screen spreading and housing device303, the second display screen302may be the flexible screen. In addition, a user may control the second display screen302to be spread from the screen spreading and housing device303or to be housed inside the screen spreading and housing device303from a spread state by controlling the terminal300. It should be noted that the locations of the first display screen and the second display screen may be exchanged. That is, the first display screen is disposed on the back side of the terminal, and the second display screen is disposed on the front side of the terminal.

In a possible implementation mode, the second display screen302and the screen spreading and housing device303are completely disposed inside the terminal300when the second display screen302is housed inside the screen spreading and housing device303. Thus, a length and a width of the terminal300may be controlled better. Further, the portability of the terminal300is improved.

In a possible implementation mode, when the second display screen302is disposed inside the screen spreading and housing device303, namely, on the back side displayed inFIG. 3, the user can directly see the second display screen302from the back side of the terminal300. The second display screen302may be operated when the second display screen302is lit up. Generally, the terminal can use the first display screen301for display and the second display screen302is off. The terminal can use the second display screen302for display when the user starts up the second display screen302.

Optionally, the screen spreading and housing device303further includes a storage component303aand a supporting component303b. The supporting component303bcorrespondingly has a contracted status and a supported status. The storage component303acan be configured to house the second display screen302. The second display screen302is spread from the storage component303aduring a process in which the supporting component303bchanges from the contracted status to the supported status. The second display screen302is housed inside the storage component when the supporting component303bchanges from the supported status to the contracted status. That is, the screen spreading and housing device303houses or spreads the second display screen302through a change of a structural form, and may house or spread the second display screen302through the form of the supporting component303b. Optionally, the storage component303amay be a storage cavity with a certain space, and the second display screen302of the terminal may be housed inside the storage cavity. That is, the second display screen302, the storage component303aand the supporting component303bare connected to one another for cooperation, such that the second display screen302may be spread from the storage component or housed inside the storage component303a.

Referring toFIG. 4which is a schematic structural diagram of a screen spreading and housing device in a contracted status according to embodiments of the present disclosure. As shown inFIG. 4, a second display screen401, the screen spreading and housing device402, a storage component402aand a supporting component402bare included. The storage component402amay be configured to house the second display screen. The supporting component402bmay be configured to spread the second display screen from the storage component or house the second display screen inside the storage component. Referring toFIG. 5which is a schematic structural diagram of a housing or spreading process of a screen spreading and housing device according to embodiments of the present disclosure. As shown inFIG. 5, a second display screen501, the screen spreading and housing device502, a storage component502aand a supporting component502bare included. Referring toFIG. 6which is a schematic structural diagram of a screen spreading and housing device in a supported status according to embodiments of the present disclosure. As shown inFIG. 6, a second display screen601, the screen spreading and housing device602, a storage component602aand a supporting component602bare included.

The second display screen is spread from the storage component when the supporting component changes from the status shown inFIG. 4to the status shown inFIG. 6, namely, from the contracted status to the supported status. The second display screen is housed inside the storage component when the supporting component changes from the status shown inFIG. 6to the status shown inFIG. 4, namely, from the supported status to the contracted status.

Optionally, the screen spreading and housing device shown inFIG. 4orFIG. 6includes the supporting component, which may include plurality of support bars. First ends of the plurality of support bars are connected to the second display screen. Moving directions of the first ends, connected to the second display screen, of the plurality of support bars are the same as a spreading or housing direction of the second display screen. It should be noted that the plurality of support bars provided by the present embodiment only take that one group of support bars (a first support bar and a second support bar) consist of two support bars as an example.

Further, the first ends of the plurality of support bars may be directly or indirectly connected to the second display screen. For example, referring toFIG. 7, which is a schematic structural diagram showing a connection between a supporting component and a second display screen. As shown inFIG. 7, a terminal700includes a first frame701, at least on group of support bars702and a second display screen703. The plurality of support bars702and the second display screen are connected to the first frame. The plurality of support bars702may indirectly enable the second display screen to be housed inside the storage component by driving the first frame701when changing from a supported status to a contracted status. Alternatively, the plurality of support bars702may indirectly enable the second display screen to be spread from the storage component by driving the first frame701when changing from the contracted status to the supported status. In the present embodiment, a specific connection mode between the first ends of the plurality of support bars and the second display screen is not limited when moving directions of the first ends of the plurality of support bars are the same as a spreading or housing direction of the second display screen.

Optionally, the at least one support bars are supported at a periphery of the second display screen when the supporting component is in the supported status. For example, as shown inFIG. 6, when the plurality of support bars shown inFIG. 6are in the supported status, the first support bar is at an upper end of the second display screen and is in the same parallel position as an upper-end frame of the terminal, and the second support bar is at a lower end of the second display screen and is in the same parallel position as a lower-end frame of the terminal, such that the plurality of support bars can protect the second display screen when the second display screen is spread.

Optionally, the plurality of support bars form a specified angle with the spreading or housing direction of the second display screen and are disposed inside the terminal when the supporting component is in the contracted status. For example, as shown inFIG. 4, when the supporting component is in the contracted status, an angle A is an angle formed between the first support bar and the housing direction of the second display screen, and an angle B is an angle formed between the second support bar and the housing direction of the second display screen. Optionally, the angle may be correlated with materials, connection modes, locations, etc. of the selected support bars when a developer designs the terminal. The specific value of the angle will not be limited in the present embodiment. Optionally, for the aesthetic appearance and the applicability of the terminal, the at least one group support bars in the contracted status may be further designed inside the terminal.

In a possible implementation mode, the plurality of support bars801are disposed on the outer side810of the second display screen when the supporting component is in the contracted status. Referring toFIG. 8which is a schematic structural diagram of a side surface of the terminal shown inFIG. 4. As shown inFIG. 8, the terminal800includes plurality of support bars801and a second display screen802. The plurality of support bars801are disposed on the outer side810of the second display screen. Thus, the support bars can protect the second display screen to a certain degree when the second display screen of the terminal is in a housed status. Further, the durability of the second display screen is improved.

In another implementation mode, the plurality of support bars are disposed on the inner side910of the second display screen when the supporting component is in the contracted status. Referring toFIG. 9which is a schematic structural diagram of another side surface of the terminal shown inFIG. 4. As shown inFIG. 9, a terminal900includes plurality of support bars901and a second display screen902. The plurality of support bars901are disposed on the inner side910of the second display screen. In this way, the support bars will not cover the second display screen when the second display screen of the terminal is in a housed status, such that the second display screen can display the content even in the housed status. Thus, the multi-faceted use performance of the terminal is improved.

For example, a display region of the second display screen902includes a housed visible region and a housed hidden region. The housed visible region can be directly observed by the user when the second display screen902is housed inside the screen spreading and housing device. The terminal may perform display through the first display screen or the housed visible region in the second display screen902when the user uses the terminal of which the second display screen902is in the housed status. The housed hidden region in the second display screen902may be off when the terminal performs display through the housed visible region in the second display screen902.

Optionally, in the terminal shown inFIG. 4, the screen spreading and housing device402may further include a servo component410connected to second ends of the plurality of support bars. The servo component410may be configured to drive the second ends of the plurality of support bars during a process in which the supporting component changes from the contracted status to the supported status, such that the first ends of the plurality of support bars move in the spreading direction of the second display screen. Correspondingly, when the second display screen needs to be housed inside the screen spreading and housing device from an spread status, the servo component410may be further configured to drive the second ends of the plurality of support bars during a process in which the supporting component changes from the supported status to the contracted status, such that the first ends of the plurality of support bars move in the housing direction of the second display screen.

Optionally, the servo component410may be an electric motor, which electrically drives the second ends of the plurality of support bars to move simultaneously in their respective fixed tracks, such that the first ends of the plurality of support bars move in the spreading direction of the second display screen. As shown inFIG. 4, a first track403is a track in which the second end of the first support bar moves, and the second track404is a track in which the second end of the second support bar moves. Optionally, the electric motor drives the second ends of the plurality of support bars to move simultaneously in their respective tracks, such that the first ends of the plurality of support bars move in the spreading direction of the second display screen, and further, the second display screen is driven to be spread from the storage component303a. That is, the second ends of the plurality of support bars are driven from a first track point to a second track point, such that the second display screen is spread. The first track point and the second ends of the plurality of support bars in the contracted status may coincide, and the second track point and the first ends of the plurality of supports in the contracted status may coincide.

Optionally, the servo component410may also be a magnetic driving component, which magnetically drives the second ends of the plurality of support bars to move simultaneously in their respective fixed tracks, such that the first ends of the plurality of support bars move in the spreading direction of the second display screen. That is, similarly, the second ends of the plurality of support bars are driven from the first track point to the second track point, such that the second display screen is spread. It should be noted that the present embodiment will not limit the specific kind of power adopted by the servo component to enable the second ends of the plurality of support bars to move in their respective fixed tracks such that the second display screen is spread from the screen spreading and housing device by the first ends of the plurality of support bars.

Similarly, the terminal drives the second ends of the plurality of support bars to move simultaneously in their respective fixed tracks through the servo component, such that the first ends of the plurality of support bars move in the housing direction of the second display screen, which may be opposite to the spreading direction of the second display screen. That is, the second ends of the plurality of support bars are driven from the second track point to the first track point, such that the second display screen changes from the spread status to the housed status. Optionally, the first track and the second track may be arc-shaped, linear, etc.

Optionally, the servo component may be controlled by a processor in the terminal. That is, the terminal shown inFIG. 4may further include the processor electrically connected to the servo component. Correspondingly, the processor may be configured to send a control signal to the servo component when acquiring a control instruction in the terminal. The control signal is configured to instruct the servo component to drive the second ends of the plurality of support bars. The control instruction may be configured to indicate that the second display screen needs to be spread from or housed inside the screen spreading and housing device.

In a possible implementation mode, the control instruction is an instruction generated when a designated key is triggered. The designated key is a physical key or a virtual key configured to control the second display screen to be housed or spread. For example, referring toFIG. 10which is a diagram showing a display interface on a front side of a terminal according to embodiments of the present disclosure. As shown inFIG. 10, the terminal1000includes a first display screen1001and a first key1002. Assuming that depressing of the first key1002corresponds to spreading of the second display screen, and restoration to the initial position corresponds to housing of the second display screen, the user can send an instruction of spreading the second display screen to the processor of the terminal by depressing the first key1002. The processor of the terminal may further generate, according to the instruction of spreading the second display screen, a signal corresponding to the signal generated when the first key is triggered, (namely, the signal is control signal sent by the processor to the servo component), the processor of the terminal sends the generated signal that corresponds to the signal generated when the first key is triggered to the servo component, such that the servo component acquires the control signal and further drives the plurality of support bars in the screen spreading and housing device to perform a track motion similar to the track motion shown inFIG. 4. Thus, the second display screen is spread.

Optionally, the first key1002shown inFIG. 10may be in the form of left-and-right slider, such that the second display screen is triggered to be spread or housed. Referring toFIG. 11which is a diagram showing another display interface on a front side of a terminal according to embodiments of the present disclosure. For example, as shown inFIG. 11, the terminal1100includes a first display screen1101and a first key1102. Assuming that leftward sliding of the first key1102corresponds to spreading of the second display screen and rightward sliding corresponds to housing of the second display screen. The terminal can generate a control signal similarly in response to the depressing of the first key when the user slides the first key leftwards, such that the control signal is sent to the servo component. Thus, the servo component acquires the control signal and further drives the plurality of support bars in the screen spreading and housing device to control the second display screen to be spread.

Optionally, a virtual key1003may be further displayed in the first display screen1001shown inFIG. 10. When the user clicks an ON key in the virtual key1003, the terminal may be triggered in response to the ON key to generate an instruction that controls the second display screen to be spread. When the user clicks an OFF key in the virtual key1003, the terminal may be triggered in response to the OFF key to generate an instruction that controls the second display screen to be housed. Further, the processor of the terminal may send the control signal, which controls the servo component to drive the second ends of the plurality of support bars, to the servo component based on the received control instruction, such that the second ends of the plurality of support bars are controlled to drive the second display screen to be spread or housed.

In a possible implementation mode, an attitude sensor, which can determine whether the first display screen is spread or not based on an attitude of the terminal, may be disposed in the terminal. For example, when the first display screen of the terminal faces away from the center of gravity, the terminal determines that the first display screen needs to be spread. When the fact that the first display screen faces away from the center of gravity is detected by the attitude sensor of the terminal, the terminal can generate a control signal similarly in response to the depressing of the first key. Thus, the control signal is sent to the servo component. The servo component acquires the control signal and further drives the plurality of support bars in the screen spreading and housing device to control the second display screen to be spread.

In a possible implementation mode, the control instruction may also be an instruction generated when a first application is started up. For example, an application is mounted in the terminal, and the user can enable the attributes of the second display screen by setting a corresponding application in a setting interface. Referring toFIG. 12which is a schematic diagram of a setting interface for enabling the second display screen according to embodiments of the present disclosure. As shown inFIG. 12, the setting interface1200includes a select control1201, an application column1202, a save control1203and a cancel control1204. For the corresponding application column1202, the user can click the select control1201and the save control1203to set an application that corresponds to the select control as the first application. When the user clicks the first application in the first display screen, the processor of the terminal can acquire an instruction (namely, the control instruction) generated when the first application is started up, such that a control signal is sent to the servo component, and the plurality of support bars of the screen spreading and housing device are controlled to drive the second display screen to be spread.

For example, when the first application selected by the user is an application XX in the terminal, the processor of the terminal can be triggered to acquire the control instruction when the user starts up the application XX later, such that the second display screen is spread. Optionally, the setting of the first application may also be that a developer sets some default applications in the terminal as the first application in advance. For example, a video application, a gate application, etc. in the terminal are set in advance. The terminal can start up the second display screen when the user starts the video application or the game application in the terminal, such that the second display screen is adopted to display interfaces of the corresponding applications.

Further, the control instruction may also be an instruction generated when the terminal receives a designated operation executed in an application interface of a second application. For example, the second application is a certain live-broadcast application. The designated operation is an operation performed by the user on a full-screen display control in the certain live-broadcast application. The user who wants to perform full-screen display on a live video can click the full-screen display control. At this time, the terminal can generate an instruction (namely, the control instruction) in response to a clicking operation performed by the user on the full-screen display control. The processor can send a control signal to the servo component to trigger the second display screen to be spread when acquiring the control instruction. Correspondingly, the processor of the terminal sends a control instruction that controls the second display screen to be housed to the servo component. For details that will not be repeated herein, referring to the above description that the processor of the terminal sends the control signal that controls the second display screen to be spread.

Optionally, when the terminal enables the first display screen or the second display screen for display, the other display screen may be off. That is, optionally, the processor in the terminal may be further electrically connected to the second display screen and the first display screen. The second display screen is controlled to be lit up during a process in which the processor controls the supporting component to change from the contracted status to the supported status. At this time, in the terminal, the first display screen may be off when the second display screen is lit up.

Optionally, the plurality of support bars of the supporting component may also be electrically connected to the processor of the terminal. A signal for lighting up the second display screen is sent to the processor at the start that the plurality of support bars of the supporting component change from the contracted status to the supported status, such that the processor lights up the second display screen. Optionally, that the signal for lighting up the second display screen is sent to the processor at the start that the plurality of support bars of the supporting component change from the contracted status to the supported status may be replaced with that the signal for lighting up the second display screen is sent to the processor during a process in which the plurality of support bars of the supporting component change from the contracted status to the supported status, or it may be replaced with that the signal for lighting up the second display screen is sent to the processor at the end that the plurality of support bars of the supporting component change from the contracted status to the supported status.

That is, the processor may control the second display screen to be lit up by the following means: the second display screen is directly lit up and the first display screen is directly turned off simultaneously at the start that the supporting component changes from the contracted status to the supported status; or the second display screen is gradually lit up along with spreading of the second display screen during a process in which the supporting component changes from the contracted status to the supported status, and correspondingly, the first display screen is gradually turned off during a process in which the supporting component changes from the contracted status to the supported status; or the second display screen is directly lit up and the first display screen is directly turned off simultaneously at the end that the supporting component changes from the contracted status to the supported status (that is, when the supporting component completely changes to the supported status).

Correspondingly, the second display screen is controlled to be off during a process in which the processor controls the supporting component to change from the supported status to the contracted status through the servo component. Optionally, referring to the method in which the processor controls the second display screen to be lit up for the method in which the processor controls the second display screen to be off, which will not be repeated herein.

In a possible implementation mode, the plurality of support bars may also adopt a telescopic design. Referring toFIGS. 13 to 15, which are schematic diagrams showing an spreading process of a second display screen of a terminal according to embodiments of the present disclosure. As shown inFIGS. 13 to 15, a terminal1300includes a second display screen1301, a first support bar1302, a second support bar1303and a storage component1304. The first support bar1302may be disposed inside an upper-end frame of the terminal, the second support bar1303may be disposed inside a lower-end frame of the terminal, and the two support bars are mutually parallel, are both telescopic bars and expand and contract to enable the second display screen1301to be spread or housed. That is, when the first support bar1302and the second support bar1303change from the contracted status to the supported status, the second display screen1301can be pushed to stretch out of the storage component1304to accomplish spreading of the second display screen. Similarly, a housing process of the second display screen is an inverse process of the above-mentioned spreading process, and therefore, will not be repeated herein. It should be noted that here is only to explain different formats and telescopic means of the support bars, other devices (for example, the servo component) included by the screen spreading and housing device are also applicable to the terminal shown inFIGS. 13 to 15, and their working principles will not be repeated herein.

In summary, the screen spreading and housing device and the second display screen cooperate with each other, such that the terminal can spread the second display screen from the screen spreading and housing device through the screen spreading and housing device. Alternatively, the terminal can house the second display screen inside the screen spreading and housing device through the screen spreading and housing device, such that the terminal can be switched between the first display screen and the second display screen. Since the flexible screen and the screen spreading and housing device are combined, both of the screen spreading and housing device and the second display screen are housed inside the terminal when the second display screen is in the contracted status, which guarantees the portability of the terminal. Moreover, instead of using the second display screen in all scenarios, the first display screen may be used or the second display screen may be spread for use as required. Thus, the power consumption of the display screens is reduced. Further, the battery durance of the terminal is improved.
