Description

Display method and device and terminal equipment

Technical Field

The present application relates to the field of multi-screen display, and in particular, to a display method, a device and a terminal device.

Background

In modern life, many people touch terminal devices in daily life, such as smart phones, tablets, smart watches, robots and the like. On the intelligent device provided with the display screen, when the intelligent device runs the application, a display interface of the application can be displayed on the display screen, so that a user can conveniently acquire information, perform man-machine interaction and the like.

With the progress of technology, the diversity demands of users have also been developed. For example, when a person performs man-machine interaction with an intelligent robot, it is desirable that the intelligent robot not only provide a convenient service, but also have an aesthetic appearance when providing the service. The embedded display screen on the intelligent robot is usually smaller, and when a user needs the robot to display the demonstration document, if the intelligent robot displays the demonstration document on the embedded display screen with smaller size, the user can be very inconvenient to watch the demonstration document. In a second scene, the intelligent robot is usually designed into an anthropomorphic shape, an embedded display screen is usually arranged at the head of the intelligent robot, and if the display screen can display expression patterns such as eyes, mouth and the like, the intelligent robot is beneficial to improving the experience of a user in man-machine interaction; if the display screen displays interfaces such as documents, settings and the like, the aesthetic feeling of the intelligent robot is reduced, so that the user experience is reduced.

How to meet the personalized demands of users in the above-mentioned scene, the service provider is still required to perfect the product.

Disclosure of Invention

The application provides a display method, a display device and terminal equipment, which are used for realizing that specific contents are displayed on a physical display screen of the terminal equipment, and not all the contents are displayed on the physical display screen of the terminal equipment.

In a first aspect, the present application provides a display method applied to a terminal device, where the terminal device includes a first physical display screen, the method includes: the system of the terminal equipment sets a default display screen of an application running on the terminal equipment as a virtual display screen, wherein the application running on the terminal equipment comprises a first application; determining a display screen for displaying the first application as the first physical display screen; the first application is displayed on the first physical display screen.

In the conventional display manner, when the terminal device is provided with a physical display screen, the default display screen of the application running on the terminal device is the physical display screen set by the terminal device, and then the physical display screen can display interfaces of various applications. However, in some scenarios, the user may not want the physical display screen of the terminal device to display the display interface of various applications, and may only want the physical display screen of the terminal device to display the display interface of a part of the applications (even only one application), so that the conventional display manner cannot meet the user requirements. In the method of the present application, the terminal device provided with the physical display screen may also create a virtual display screen, and set the default display screen of the application running on the terminal device as the virtual display screen, that is, the interfaces of various applications to be displayed will be displayed on the virtual display screen, instead of the physical display screen; and setting the display screen of the first application as a first physical display screen of the terminal equipment, and displaying the first application on the first physical display screen. After the method is adopted, the physical display screen of the terminal equipment can be used for displaying specific applications, and other applications are displayed on the virtual display screen. For example, for an intelligent robot, the first application may be an expression application, and then the physical display screen of the intelligent robot only displays the expression application, which will make the intelligent robot have an anthropomorphic form, and improve the aesthetic property of the intelligent robot, thereby helping to improve the user experience.

In one possible implementation manner, the determining the display screen for displaying the first application as the first physical display screen includes: determining a display screen of a first interface for displaying the first application as the first physical display screen; the displaying the first application on the first physical display screen includes: and displaying a first interface of the first application on the first physical display screen. In the above implementation manner, when configuring the content displayed on the first physical display screen, setting may be performed not only with the granularity of the application but also with the granularity of the interface. For example, the expression interface in the expression application is displayed on the physical display screen of the intelligent robot, but the setting interface of the expression application may not be displayed on the physical display screen.

In a possible implementation manner, the application running on the terminal device further comprises a second application; the method further comprises the steps of: and carrying the display data of the second application through the virtual display screen. In the above implementation, other applications running on the terminal device may be displayed on the virtual display screen (the content displayed on the virtual display screen is not visible to the user, but the content on the virtual display screen may be displayed by connecting the peripheral display device) instead of being displayed on the physical display screen of the terminal device. For example, when the user performs language setting on the intelligent robot, the data of the setting application of the intelligent robot is not displayed on the physical display screen, but the virtual display screen carries the display content of the setting application, and the physical display screen still displays the content of the first application.

In one possible implementation, the carrying, by the virtual display screen, display data of the second application includes: and setting a default display screen of an application running on the terminal equipment as a virtual display screen according to the system of the terminal equipment, and carrying display data of the second application through the virtual display screen.

In one possible implementation, the terminal device further includes a second physical display screen; the method further comprises the steps of: determining a display screen of a second interface for displaying the first application as the second physical display screen; and displaying a second interface of the first application on the second physical display screen. In the embodiment of the application, the interface can be set as granularity, when the terminal equipment comprises a plurality of physical display screens, the display screen of the first interface of the first application can be set as a first physical display screen, and the display screen of the second interface of the first application can be set as a second physical display screen, so that the appointed content is displayed on the first physical display screen, other contents are displayed on the second physical display screen, or other appointed contents are displayed on the second physical display screen. For example, the expression interface in the expression application is displayed on the first physical display screen on the front side of the intelligent robot, but the setting interface of the expression application can be displayed on the second physical display screen on the back side of the intelligent robot, so that the first physical display screen on the front side of the intelligent robot always displays the expression interface of the application, and the aesthetic property and the harmony of the appearance of the intelligent robot are maintained.

In one possible implementation, the application running on the terminal device further includes a third application; the method further comprises the steps of: determining a display screen for displaying the third application as the second physical display screen; and displaying the third application on the second physical display screen. In this implementation manner, the setting may be performed with the application as granularity, and the display screen of the first application may be set as the first physical display screen, and the display screen of the third application may be set as the second physical display screen, so that different physical display screens of the terminal device display different applications.

In this implementation manner, the multiple interfaces of the first application may be displayed on the first physical display screen of the terminal device, and then, after the terminal device receives the instruction for switching the interface of the first application, the interface after switching may still be displayed on the first physical display screen. For example, the expression application running on the intelligent robot is a first application, and the first application may include a smiling expression interface and a gas expression interface, so that the intelligent robot may switch the expression interface displayed on the first physical display screen according to a switching instruction directly input by a user or according to a switching instruction generated by man-machine interaction content.

In a possible implementation manner, the application running on the terminal device further includes a fourth application; the method further comprises the steps of: determining a display screen for displaying the fourth application as the first physical display screen; receiving a second switching instruction, wherein the second switching instruction is used for indicating switching to the fourth application; and displaying the interface of the fourth application on the first physical display screen according to the second switching instruction. In this implementation manner, both the first application and the fourth application may be displayed on the first physical display of the terminal device, and if the content of the first application is currently displayed, after the terminal device receives the instruction for switching the application, the content of the second application after switching may be displayed on the first physical display.

In one possible implementation manner, the terminal device is connected with a peripheral display device; the method further comprises the steps of: and sending the display data borne by the virtual display screen to the peripheral display equipment for display. Because the display data borne by the virtual display screen is invisible to the user, in order to facilitate the user to watch the data displayed by the virtual display screen, the display data borne by the virtual display screen can be sent to the connected peripheral display equipment for display.

Detailed Description

On a terminal device with a display screen, when a user opens an application installed on the terminal device, the terminal device can display an interface on the display screen of the terminal device by default, and the user can watch through the display screen. In addition, the terminal equipment can display the content displayed on the display screen of the terminal equipment on a television or other display equipment in a screen throwing mode, so that better watching experience is brought to the user.

A screen projection technology synchronously displays the content displayed by a source device to a screen projection device for display, namely the screen projection device and the source device display the same content. For example, in the teaching process of a teacher, a computer (i.e. a source device) can be used for opening a teaching file, but due to the fact that a display screen of the used computer is small, students are difficult to see the content displayed by the computer clearly, then the teacher can screen the content displayed by the computer onto a display device (i.e. a screen-projection device) with a larger size, which is installed in a classroom, at the moment, the display device displays the same content as the computer, and operations (such as page turning and new application opening) of the teacher on the computer are synchronously displayed on the display device.

The other screen projection technology is to project a target application interface of the source device onto the screen projection device, wherein the target application can be an application running in the foreground or the background on the source device and can be designated by a user to project the screen, and when the target application is transferred to the background for running, the application interface displayed by the screen projection device is not influenced, so that the source device and the screen projection device can display interfaces of different applications. For example, a user can first open a movie to be played through a video application on a mobile phone and throw the movie on a television to be played, so that the user can watch the movie through a television with a larger display screen, and during the screen throwing, the user can still use the mobile phone to communicate, work and play games without affecting the playing of the movie. The above-mentioned screen projection mode is generally a wireless screen projection scheme based on a Digital Living Network Alliance (DLNA) protocol, however, the wireless screen projection scheme based on the DLNA protocol can only project pictures, audio and video, but cannot project other types of content (such as presentations, chat information, etc.).

Furthermore, for the second screen projection method, even though the content projected to the screen projection device is the display content of the target application specified by the user regardless of the limitation of the screen-projectable type, in some application scenarios, for example, for the intelligent robot, the user may want the display screen of the intelligent robot to display the target application, while the content of other applications is not displayed on the display screen or is displayed on other display devices, so that the above scheme cannot be implemented.

In view of this, the embodiments of the present application provide a display method capable of displaying specific contents on a physical display screen of a terminal device, instead of displaying all the contents on the physical display screen of the terminal device.

The method can be applied to an intelligent terminal with a physical display screen, such as a mobile phone, a computer, a tablet computer, an intelligent robot, a Personal Digital Assistant (PDA), a vehicle-mounted computer, a wearable device and the like.

The following describes the respective constituent elements of the terminal device 100 in detail with reference to fig. 1:

The processor 110 is a control center of the terminal device 100, connects various parts of the entire terminal using various interfaces and lines, and performs various functions of the terminal device 100 and processes data by running or executing computer programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the terminal.

Optionally, the processor 110 may include one or more processing units. The processor 110 may integrate an application processor that primarily handles operating systems, user interfaces, applications, etc., with a modem processor that primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 110.

The memory 120, which may be used to store computer programs and data, the processor 110 performs various functional applications of the terminal device 100 and data processing by running the computer programs stored in the memory 120 in advance. The memory 120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system (e.g., an android operating system or an IOS operating system), an application program required for at least one function; the storage data area may store data created according to the use of the terminal device 100, etc., such as contact information, etc.

The display 130 may be used to display various application interfaces of the terminal device 100, and further, may also display information input by a user or information provided to the user, and may also accept user input. The specific display 130 may include a display panel 131, and a touch panel 132. The display panel 131 may be configured in the form of a Liquid Crystal Display (LCD) CRYSTAL DISPLAY, an organic light-emitting diode (OLED), or the like. The touch panel 132, also referred to as a touch screen, a touch sensitive screen, etc., may collect touch or non-touch operations on or near the user (e.g., operations of the user using any suitable object or accessory such as a finger, a stylus, etc., on or near the touch panel 132, may also include somatosensory operations; the operations include operation types such as single-point control operations, multi-point control operations, etc.), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 132 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch azimuth and the touch gesture of a user, detects signals brought by touch operation and transmits the signals to the touch controller; the touch controller receives touch information from the touch detection device, converts the touch information into information which can be processed by the processor, sends the information to the processor 110, and can receive and execute commands sent by the processor 110. In addition, the touch panel 132 may be implemented by various types such as resistive, capacitive, infrared, and surface acoustic wave, and the touch panel 132 may be implemented by any technology developed in the future. Further, the touch panel 132 may cover the display panel 131, and a user may perform an operation on or near the touch panel 132 covered on the display panel 131 according to the content (the display content includes, but is not limited to, a soft keyboard, a virtual mouse, virtual keys, icons, etc.) displayed on the display panel 131, and the touch panel 132 detects an operation thereon or near. Although in fig. 1, the touch panel 132 and the display panel 131 implement the input and output functions of the terminal device 100 as two separate components, in some embodiments, the touch panel 132 and the display panel 131 may be integrated to implement the input and output functions of the terminal device 100.

The charge management module 140 is configured to receive a charge input from a charger. The power management module 141 is used for connecting the battery 142, and the charge management module 140 and the processor 110. The power management module 141 receives input from the battery 142 and/or the charge management module 140 to power the processor 110, the memory 120, the display 130, and the like.

Audio circuitry 150, speaker 151, and microphone 152 may provide an audio interface between a user and terminal device 100. The audio circuit 150 may be used to convert audio data into a signal recognizable by the speaker 151 and transmit the signal to the speaker 151 for conversion by the speaker 151 into a sound signal output. The microphone 152 is used for collecting external sound signals (such as voice uttered by a person, or other sounds, etc.), converting the collected external sound signals into signals that can be recognized by the audio circuit 150, and transmitting the signals to the audio circuit 150. The audio circuit 150 may also be used to convert the signal transmitted by the microphone 152 into audio data, which is then output to the RF circuit 170 for transmission to other devices, or to the memory 120 for subsequent further processing.

Other input devices 160 may be used to receive entered numeric or character information and to generate key signal inputs related to user settings and function control of the terminal device 100. In particular, other input devices 160 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, a light mouse (a light mouse is a touch-sensitive surface that does not display visual output, or an extension of a touch-sensitive surface formed by a touch screen), and the like.

The RF circuit 170 may be used for receiving and transmitting signals during the process of receiving and transmitting information or communication, and specifically, may transmit the received information to the processor 110 for processing; in addition, the information sent by the processor 110 is acquired and sent to other devices. Typically, RF circuitry includes, but is not limited to, antennas, at least one amplifier, transceivers, couplers, low noise amplifiers (low noise amplifier, LNAs), diplexers, and the like. In addition, the RF circuitry 170 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol including, but not limited to, global system for mobile communications (global system of mobile communication, GSM), general packet radio service (GENERAL PACKET radio service, GPRS), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), long term evolution (long term evolution, LTE), email, short message service (short MESSAGING SERVICE, SMS), and the like.

Wi-Fi technology belongs to a short-distance wireless transmission technology, and the terminal device 100 can be connected with an Access Point (AP) through a Wi-Fi module 180, so as to realize access to a data network. The Wi-Fi module 180 may be used to receive and transmit data during communication.

Although not shown, the terminal device 100 may further include a camera, at least one sensor, etc., which will not be described herein. The at least one sensor may include, but is not limited to, a pressure sensor, a barometric pressure sensor, an acceleration sensor, a distance sensor, a fingerprint sensor, a touch sensor, a temperature sensor, and the like.

In order to facilitate understanding of the embodiments of the present application, concepts related to the embodiments of the present application will be described first.

A physical display screen, representing an actual display device, such as an LED display, LCD display, OLED display, etc., whose display content is visible to the user. The touch display screen arranged on the mobile phone, the touch display screen arranged on the tablet, the display screen arranged on the notebook computer, the display screen arranged on the robot and used for man-machine interaction and the like are physical display screens.

The virtual display screen is a virtual display screen, which can be created through software programming relative to a physical display screen of the terminal equipment, and can be used for bearing interface contents of an application operated by the terminal equipment, wherein the virtual display screen is visually invisible to a user of the terminal equipment, and the borne interface contents can be displayed through a designated display screen equipment, such as a peripheral terminal equipment or a terminal equipment which currently generates the virtual display screen.

Fig. 2 is a schematic flow chart of a display method according to an embodiment of the present application, where the method may be applied to a terminal device including a first physical display screen, and the terminal device may be a terminal device as shown in fig. 1. The first physical display screen can be embedded on the terminal equipment, for example, the display screen of the mobile phone is embedded on the mobile phone; or the first physical display screen can also be a computer externally connected to the terminal equipment, for example, the host computer is connected with the display screen through a data line. As shown in fig. 2, the method may include the steps of:

Step 201, the system of the terminal device sets a default display screen of an application running on the terminal device as a virtual display screen.

Setting the default display of the application running on the terminal device as a virtual display, then when the user opens a certain application of the terminal device, the content of the application will be displayed on the default display, i.e. on the virtual display, instead of on the physical display of the terminal device.

Program codes for executing the above steps may be written into a system of a terminal device, and when the terminal device starts the system, the above step 201 is executed, thereby executing the display method provided by the embodiment of the present application.

Optionally, the system may be an operating system installed in the terminal device, and when the terminal device is started to start the test running operating system, the terminal device may execute the display method provided by the embodiment of the present application. Further, the terminal device may create the virtual display screen when running the operating system.

Or the system can be installed on the terminal device in an application mode, and when a user opens the application, the terminal device runs the system and then executes the display method provided by the embodiment of the application. The terminal device may create the virtual display screen described above while running the system.

The manner in which the terminal device creates the virtual display may vary from operating system to operating system. For example, if the terminal device is installed in an android system, a display screen can be cloned from a default physical display screen of the system to be used as a virtual display screen when the system is started, or a virtual display screen can be created by calling to create a virtual display (createVirtualDisplay) interface; if the terminal equipment is installed as an IOS system, a virtual display screen can be created by calling [ [ UIWindow alloc ] INITWITHFRAME: [ UIScreen mainScreen ] bounds ] interfaces; if the terminal device is installed in a Windows system, a virtual display screen can be created by calling a virtual display (VirtualDisplay) and a screen extension (ScreenExpander).

Further, when the terminal device creates the virtual display screen, the resolution of the virtual display screen may be further set. The size of the resolution can be defined by the system described above. For example, the user may implement the definition of the resolution of the virtual display screen by modifying the program of the system, or the system may also provide a setting interface for the resolution of the virtual display screen, so that the user may set the resolution, and then create a corresponding virtual display screen according to the resolution set by the user.

Step 202, a system of the terminal equipment determines a display screen for displaying a first application as a first physical display screen, wherein the first application is an application running on the terminal equipment.

A plurality of applications may be installed and run on the terminal device, which may include a first application. Although in step 201 the system of the terminal device sets the default display of the application (including the first application) running on the terminal device as the virtual display, in step 202, the display of the first application is set as the first physical display, and then the display data of the first application will not be displayed on the virtual display, but on the first physical display of the terminal device.

The first application is an application which is expected to be displayed on a first physical display screen of the terminal equipment by a user, for example, for the intelligent robot, in order to make the appearance of the intelligent robot more anthropomorphic, the user may expect the first physical display screen arranged on the head of the intelligent robot to display expression applications, such as eyes, mouth and the like under various expressions, so that the intelligent robot is more lovely, and the man-machine interaction feeling of the user is improved.

When the system is an operating system of the terminal equipment, the first application is predetermined and written into program codes of the system; when the terminal device performs the above step 202, the step can be performed without the user selecting the first application. For example, for an intelligent robot, an expression application as a first application may be defined at the time of product production without user operation. In other scenarios, the first application may also be selected by the user, that is, the terminal device determines the first application according to information input by the user, and further determines a display screen of the first application as the first physical display screen.

Step 203, the system of the terminal device instructs to display the first application on the first physical display screen.

Specifically, the terminal device encodes display data of the first application, and displays the encoded data through the first physical display screen.

In the conventional display manner, when the terminal device is provided with a physical display screen, the default display screen of the application running on the terminal device is the physical display screen set by the terminal device, and then the physical display screen can display interfaces of various applications. However, in some scenarios, the user may not want the physical display screen of the terminal device to display the display interface of various applications, and may only want the physical display screen of the terminal device to display the display interface of a part of the applications (even only one application), so that the conventional display manner cannot meet the user requirements.

In the method of the present application, the terminal device provided with the physical display screen may also create a virtual display screen, and set the default display screen of the application running on the terminal device as the virtual display screen, that is, the interfaces of various applications to be displayed will be displayed on the virtual display screen, instead of the physical display screen; and setting the display screen of the first application as a first physical display screen of the terminal equipment, and displaying the first application on the first physical display screen. After the method is adopted, the physical display screen of the terminal equipment can be used for displaying specific applications, and other applications are displayed on the virtual display screen. For example, for an intelligent robot, the first application may be an expression application, and then the physical display screen of the intelligent robot only displays the expression application, which will make the intelligent robot have an anthropomorphic form, and improve the aesthetic property of the intelligent robot, thereby helping to improve the user experience.

When the terminal device executes the step 202, that is, when the terminal device determines that the display screen of the first application is the first physical display screen, the terminal device may set the application as granularity, or may set the interface as granularity.

Specifically, setting is performed with the application as granularity, and all interfaces representing the first application can be displayed on the first physical display screen. Taking the first application as an example of the expression application, an expression interface (such as a smile eye display interface, a gas eye display interface and the like) of the expression application, a setting interface of the expression application and the like can be displayed on a first physical display screen, so that a user can conveniently operate the first application.

Further, since the setting is performed with the application as granularity, the interfaces of the first application can be all displayed on the first physical display screen, and then the terminal device can switch the interface of the first application displayed on the first physical display screen according to the switching instruction. For example, when the intelligent robot currently displays a gas expression interface in an expression application (i.e., a first application), and when the voice information received by the intelligent robot through the microphone is "smiling" and the voice information is judged to be a smiling expression interface in an expression application through semantic recognition, the intelligent robot can generate a switching instruction, and then the system of the intelligent robot can display the smiling expression interface in the expression application on the first physical display screen after acquiring the switching instruction. Or the intelligent robot can also autonomously select the expression suitable for the current interaction information according to the current man-machine interaction information and generate a switching instruction, for example, when the user exaggerates the intelligent robot to be lovely, the intelligent robot can select to switch to a happy expression interface or switch to a shy expression interface. In addition, the switching instruction may be directly input to the intelligent robot by the user.

When the interface is set as granularity, the system of the terminal equipment can set the display screen for displaying the first interface of the first application as the first physical display screen, and then the terminal equipment displays the first interface of the first application on the first physical display screen. Of course, the display screen of the plurality of interfaces of the first application may also be set as the first physical display screen. For example, for the expression application, the display screen of the smile eye interface, the angry eye interface, and the crying eye interface may be set as the first physical display screen, and the unset interface (such as the setting interface of the expression application) is displayed on the virtual display screen.

Further, when the granularity of the interface is set, if the display screens of the interfaces of the first application are set as the first physical display screen, the terminal device may also switch the interface of the first application displayed on the first physical display screen according to the switching instruction, and the interface after switching should also be the interface allowed to be displayed on the first physical display screen after being set. For example, the smiling expression interface, the gas expression interface, and the display screen corresponding to the crying expression interface of the expression application have been set as the first physical display screen, but the display screen corresponding to the setting interface in the expression application is not set as the first physical display screen, so when the system of the intelligent robot receives the switching instruction for switching to the smiling expression interface, the intelligent robot displays the smiling expression interface on the first physical display screen, and when the system of the intelligent robot receives the switching instruction for switching to the setting interface of the expression application, the intelligent robot does not display the setting interface on the first physical display screen.

Further, in the above step 202, in addition to determining the display screen of the first application as the first physical display screen, display screens of more applications may be determined as the first physical display screen. For example, the system of the terminal device may determine the display screen of the expression application and the picture application as a first physical display screen; the terminal equipment displays the content of the expression application on the first physical display screen at present, and when the terminal equipment generates a switching instruction for switching to the picture application according to the man-machine interaction information, the terminal equipment can switch the content displayed on the first physical display screen into the content of the picture application.

As previously mentioned, a plurality of applications may be running on the terminal device. For a second application (different from the first application) of the plurality of applications, since its corresponding display screen has been set as a virtual display screen and the display screen of the second application has not been set as a physical display screen in step 201, when the terminal device runs the second application, the terminal device will carry display data of the second application through the virtual display screen. Since the display data of the second application is displayed on the virtual display screen, not on the physical display screen of the terminal device, the user cannot see the display data of the second application through the physical display screen of the terminal device. For example, when the user performs language setting on the intelligent robot, the data of the setting application of the intelligent robot is not displayed on the physical display screen, but the virtual display screen carries the display content of the setting application, and the physical display screen still displays the content of the first application.

Specifically, when the terminal device executes the step 201, setting a default display screen of an application running on the terminal device as a virtual display screen, that is, setting the default display screen of the second application as virtual display is realized; when the terminal equipment runs the second application, the display data of the second application is carried through the virtual display screen. Or the terminal device may also carry the display data of the second application through the virtual display screen in other manners, for example, the terminal device may also set the second application separately, and set the default display screen of the second application as the virtual display screen.

In one possible implementation, the terminal device may also be connected with a peripheral display device. The peripheral display device is a device which is outside the terminal device and can be used for display. For example, the peripheral display device may be a display, a computer, a television, or the like; or the peripheral display device may be a device that does not have a display screen itself but has a display function, such as a projector or the like. The terminal device and the peripheral display device may be connected in a wireless or wired manner, for example, the terminal device may be connected to the peripheral display device through a universal serial bus (universal serial bus, USB) interface, a high-definition multimedia interface (high definition multimedia interface, HDMI) or other interfaces, and the terminal device may also be connected to the peripheral display device through wireless communication manners such as wireless fidelity (WIRELESS FIDELITY, wi-Fi), wireless local area network (wireless local area network, WLAN), bluetooth (bluetooth), and the like.

When the terminal device is connected with the peripheral display device, the terminal device can send the display content carried by the virtual display screen to the peripheral display device for display, for example, display data of the second application. The display content borne by the virtual display screen cannot be perceived by a user, and if the user wishes to view the display content borne by the virtual display screen, the terminal device can be connected with the peripheral display device, and the display content borne by the virtual display screen is displayed through the peripheral display device.

Specifically, the terminal device displays the display content borne by the virtual display screen through the peripheral display device, and the display content borne by the virtual display screen needs to be sent to the peripheral display device. And the mode of sending the display content by the terminal equipment is related to the connection mode of the terminal equipment and the peripheral physical display equipment. For example, if the terminal device is connected to the peripheral physical display device through a USB interface, the terminal device may send the content displayed by the virtual display screen to the peripheral physical display screen based on a USB standard protocol; if the terminal device and the peripheral physical display device pass through Wi-Fi, the terminal device may send the content displayed by the virtual display screen to the peripheral physical display screen based on a WiFi wireless screen-throwing protocol, where the WiFi wireless screen-throwing protocol includes, but is not limited to, a Miracast protocol, and a blank play (AirPlay) protocol.

In a specific embodiment, the intelligent robot needs to carry out intelligent lecture, although slides used by the lecture are input to the intelligent robot, because the display screen arranged on the head of the intelligent robot is small in size, if the slides are displayed on the display screen, a viewer may need to watch the content of the clear slides in a short distance, and when the viewer is more, the viewer at the rear row may not see even the display screen of the intelligent robot, so that the user experience is poor; and the slide is displayed on the display screen of the intelligent robot, the whole aesthetic property of the intelligent robot is also poor. In order to solve the problem, the display method provided by the embodiment of the application can be applied to the intelligent robot, and the expression application is set as the first application. Then the intelligent robot will run the system after power-on, create a virtual display screen, and the default display screen of the various applications will be set as the virtual display screen, and then the display data of the various applications will not be displayed on the physical display screen of the intelligent robot. The intelligent robot sets the display screen of the expression application as a physical display screen, and then the display data of the expression application can be displayed on the physical display screen of the intelligent robot, so that the physical display screen can display smiling eyes, puzzling eyes and angry eyes, the expression currently displayed by the intelligent robot is matched with the output voice information, and the intelligent robot is more personified, and better user experience is brought. When the intelligent robot plays a presentation, the slide is opened, then the slide will be displayed on the virtual display screen. The user can also access the intelligent robot and the huge display screen (namely the peripheral display equipment) into a network (the same Wi-Fi network can be accessed, or different Wi-Fi networks can be accessed, or other networks capable of performing wireless communication can be accessed), and the intelligent robot and the huge display screen are in wireless connection. Finally, the intelligent robot sends the display content carried by the virtual display screen to the huge display screen through wireless connection, and the huge display screen can display the content of the slide, so that the audience can watch the content of the slide through the huge display screen.

Optionally, the terminal device may further include a second physical display screen. For example, a first physical display screen may be disposed at a front position of a head of the intelligent robot, and a second physical display screen may be disposed at a rear surface of the intelligent robot.

In some embodiments, the terminal device may set the display screen of the second interface of the first application as the second physical display screen, and display the second interface of the first application on the second physical display screen. For example, taking a terminal device as an intelligent robot and taking an expression application as an example, a first physical display screen disposed on the front surface of the intelligent robot may be used to display an expression display interface (such as an interface of smiling eyes, an interface of angry eyes, and an interface of crying eyes) of an expression. The display screen of the interface other than the expression display interface (such as the setting interface of the expression application) can be set as a second physical display screen, so that the first physical display screen is only used for displaying the expression, the anthropomorphic state of the terminal equipment is kept, and the setting interface is displayed in the second physical display screen, so that the user performs man-machine interaction.

In other embodiments, a third application may also be run on the terminal device, and the display screen of the third application is set to be a second physical display screen, and the third application is displayed on the second physical display screen. For example, the intelligent robot may run an expression application (acting as a first application) and a setting application (acting as a third application), and the intelligent robot may display the expression application on the front first physical display screen and display the setting application on the back second physical display screen, so as to facilitate the user to set the intelligent robot (such as language setting).
