As can be seen from fig. 5 and 6, the first display 01 and the second display 02 may be disposed opposite to each other. For example, the first display 01 may be located on the front side of the mobile terminal 00, and the second display 02 may be located on the rear side of the mobile terminal 00.
In another alternative implementation, referring to fig. 7, fig. 7 shows a schematic structural diagram of another mobile terminal.

Under the scene that the mobile terminal comprises the first display screen and the second display screen, both the first target application interface and the second target application interface can be obtained based on the first initial application interface displayed by the first display screen.
In an alternative implementation, the content displayed by the first target application interface and the content displayed by the second target application interface may be the same. In another alternative implementation, the content displayed by the first target application interface and the content displayed by the second target application interface may be different. For example, a first target application interface may be derived based on a first sub-initial application interface of the first initial application interface, and a second target application interface may be derived based on a second sub-initial application interface of the first initial application interface. The first sub-initial application interface can be a main interface of the first initial application interface, and the second sub-initial application interface can be a floating interface which is displayed on the main interface in an overlapping mode.

Alternatively, the first target application interface may be obtained based on a first initial application interface displayed on the first display screen, and the second target application interface may be obtained based on a second initial application interface displayed on the second display screen. The first initial application interface and the second initial application interface may be the same or different. Correspondingly, the content displayed by the first target application interface and the content displayed by the second target application interface can be the same or different.
In the embodiment of the present application, taking the mobile terminal including the first display screen and the second display screen as an example, and taking the mobile terminal and the first projection device and the second projection device as an example, the projection method of the mobile terminal provided in the embodiment of the present application is exemplarily described:
the following embodiments exemplarily illustrate the projection method of the mobile terminal provided by the embodiments of the present application, where the first target application interface is obtained based on the first initial application interface, and the second target application interface is obtained based on the second initial application interface.
Fig. 8 is a flowchart of a projection method of a mobile terminal according to an embodiment of the present disclosure. The method may be applied to a mobile terminal, such as the mobile terminal shown in any of fig. 5 to 7. The mobile terminal may include: the display device comprises a first display screen and a second display screen. And, the mobile terminal may be configured to connect with the first projection device and the second projection device, respectively. Referring to fig. 8, the method may include:
step 301, acquiring a first initial application interface displayed by a first display screen and a second initial application interface displayed by a second display screen.
After the mobile terminal is determined to be connected with the first projection device and the second projection device, a first initial application interface displayed by a first display screen of the mobile terminal and a second initial application interface displayed by a second display screen of the mobile terminal can be obtained. The mobile terminal can be connected with the first projection device through the first interface and can be connected with the second projection device through the second interface. Alternatively, the first projection device and the second projection device may be placed on the same stand.
Optionally, the mobile terminal may directly obtain a first initial application interface displayed by the first display screen and a second initial application interface displayed by the second display screen. Or, the mobile terminal may obtain the layer source data corresponding to the first initial application interface and the layer source data corresponding to the second initial application interface.
Optionally, the level of the interface (i.e., the first interface or the second interface) of the mobile terminal is different before and after the interface is connected to the projection device (i.e., the first projection device and the second projection device). For example, when the interface is not connected to the projection device, the level is low. After the interface is connected with the projection equipment, the electric level of the interface is converted from low electric level to high electric level. Therefore, the mobile terminal can detect whether the projection device is connected to the first interface by detecting the level of the interface.
For example, if the mobile terminal determines that the level of the first interface is changed from a low level to a high level, it may be determined that the first interface is connected with the first projection device. If the mobile terminal determines that the level of the second interface is converted from the low level to the high level, it may be determined that the second interface is connected to the second projection device. And then, the mobile terminal can obtain a first initial application interface displayed by the first display screen and a second initial application interface displayed by the second display screen.
In this embodiment, the processor of the mobile terminal generally sends the initial application interfaces (i.e., the first initial application interface and the second initial application interface) to the display screens (i.e., the first display screen and the second display screen) of the mobile terminal through a Mobile Industry Processor Interface (MIPI) and based on a display serial interface specification (DSI). Correspondingly, the data format of the first initial application interface and the data format of the second initial application interface can both be in the MIPI format.
Optionally, the first initial application interface and the second initial application interface may be the same. Accordingly, the content projected and displayed by the subsequent first projection device may be the same as the content projected and displayed by the second projection device. Alternatively, the first initial application interface and the second initial application interface may be different. Accordingly, the content projected and displayed by the first projection device may be different from the content projected and displayed by the second projection device.
In an embodiment of the present application, the first initial application interface may include: a first sub-initial application interface and a second sub-initial application interface. In this case, the mobile terminal may be connected to two first projection devices, and one of the two first projection devices may project and display a resulting interface based on the first sub-initial application interface. The other of the two first projection devices may project and display an interface based on the second sub-initial application interface.
Optionally, the first sub-initial application interface and the second sub-initial application interface may be two sub-initial application interfaces displayed in an overlapping manner. For example, the first sub-initial application interface is a main interface of the first initial application interface displayed on the first display screen, and the second sub-initial application interface is a floating interface displayed on the main interface of the first initial application interface in an overlapping manner.
Or the first initial application interface comprises two sub initial application interfaces after the screen is split. For example, the first sub-initial application interface may be a portion of the application interface near the bottom of the mobile terminal, and the second sub-initial application interface may be a portion of the application interface away from the bottom of the mobile terminal.
In an embodiment of the present application, the second initial application interface may also include: a third sub-initial application interface and a fourth sub-initial application interface. In this case, the mobile terminal may further be connected to two second projections, one of the two second projection devices may project and display an interface obtained based on the third sub-initial application interface, and the other of the two second projection devices may project and display an interface obtained based on the fourth sub-initial application interface.
Optionally, the third sub-initial application interface and the fourth sub-initial application interface may be two sub-initial application interfaces displayed in an overlapping manner. For example, the third sub-initial application interface is a main interface of the second initial application interface displayed on the second display screen, and the fourth sub-initial application interface is a floating interface displayed on the main interface of the second initial application interface in an overlapping manner.
Or the first initial application interface comprises two sub initial application interfaces after the screen is split. For example, the first sub-initial application interface may be a portion of the application interface near the bottom of the mobile terminal, and the second sub-initial application interface may be a portion of the application interface away from the bottom of the mobile terminal.
Step 302, adjusting the resolution of the first initial application interface to a first target resolution, and/or converting the data format of the first initial application interface into a first target format to obtain a first target application interface.
After the mobile terminal acquires the first initial application interface displayed by the first display screen, the resolution of the first initial application interface can be adjusted to the first target resolution, and/or the data format of the first initial application interface is converted into the first target format, so that the first target application interface is obtained. For example, after the mobile terminal acquires the first initial application interface, the resolution of the first initial application interface may be adjusted to the first target resolution, and the data format of the first initial application interface may be adjusted to the first target format, so as to obtain the first target application interface.
In this embodiment of the application, for a scenario in which the mobile terminal acquires the first initial application interface, the mobile terminal may directly adjust the resolution of the first initial application interface, and/or convert the data format of the first initial application interface. Therefore, the resolution of the first initial application interface is the first target resolution, and/or the data format of the first initial application interface is the first target format, so as to obtain the first target application interface.
For a scene in which the mobile terminal obtains layer source data corresponding to the first initial application interface, the mobile terminal may first obtain a first initial layer based on the first target resolution and the layer source data, and then may convert the data format of the first initial layer into a first target format to obtain a first target application interface.
Wherein the first target resolution may be a resolution which is stored in advance by the mobile terminal and is close to the resolution of the projection device. Therefore, the first target application interface can be ensured to be high in adaptation degree with the first projection device, and the projection display effect of the first projection device can be ensured.
Alternatively, the first target resolution is the resolution of the first projection device. Therefore, the first target application interface sent by the mobile terminal to the first projection device can be ensured to be adapted to the first projection device, and the projection display effect of the first projection device can be ensured.
Optionally, for a scene in which the first target resolution is the resolution of the first projection device, the first projection device may report the device information to the mobile terminal after accessing the first interface. Accordingly, the mobile terminal can obtain the device information. The device information may include a resolution of the first projection device. The device information may also include a model number and a frame rate of the first projection device, and so on.
In this embodiment, the first target format is a data display format of the first projection device. Since the projection device generally receives data through a High Definition Multimedia Interface (HDMI), the first target format is an HDMI format.
Optionally, the mobile terminal may further include: and the signal converter is respectively connected with the processor and the first interface. For a scenario in which a processor of the mobile terminal acquires the first initial application interface, the processor may send the first initial application interface to the signal converter after acquiring the first initial application interface. After the signal converter receives the first initial application interface, the data format of the first initial application interface can be converted from the MIPI format to the HDMI format.
For a scene in which a processor of the mobile terminal acquires layer source data corresponding to a first initial application interface, the processor may send a first initial layer to the signal converter after drawing the first initial layer based on the layer source data and a first target resolution of the first initial application interface. After receiving the first initial layer, the signal converter can convert the data format of the application interface of the first initial layer from the MIPI format to the HDMI format, thereby obtaining a first target application interface.
The signal converter may be connected to the processor of the mobile terminal through an integrated circuit (I2C) bus. Before the processor sends the first initial application interface and the first initial layer to the signal converter, the processor may execute a pre-stored driving code to drive the signal converter, so that the signal converter may perform format conversion after receiving the first initial application interface or the first initial layer.
Alternatively, the signal converter may be an LT8912 chip.
Optionally, for a scenario in which the mobile terminal is connected to two first projection devices (i.e., the first initial application interface includes a main interface and a floating interface), the first target application interface may include: a first sub-target application interface and a second sub-target application interface. Wherein the first sub-target application interface can be obtained based on a first sub-initial application interface (e.g., a home interface) of the first initial application interface, and the second sub-target application interface can be obtained based on a second sub-initial application interface (e.g., a hover interface) of the first initial application interface.
For example, the mobile terminal may adjust the resolution of the main interface of the first initial application interface to the first target resolution, and/or adjust the data format of the main interface to the first target format, so as to obtain the first sub-target application interface. And the mobile terminal can adjust the resolution of the floating interface of the first initial application interface to the first target resolution, and/or adjust the data format of the floating interface to the second target format, so as to obtain the second sub-target application interface.
Optionally, for a scene in which the mobile terminal is connected with the two first projection devices, in the process of converting the data format of the main interface and the data format of the floating interface by the mobile terminal, different signal converters may be controlled to respectively convert the data formats of the main interface and the floating interface.
For example, the mobile terminal may include a plurality of signal converters in one-to-one correspondence with a plurality of projection devices. Each signal converter may be connected to the processor via an I2C bus and to an interface of one of the mobile terminals.
It should be noted that, for a scenario in which the mobile terminal includes a plurality of signal converters, the driving codes of the plurality of signal converters may be different. The driver code may be recorded with the address of the signal converter.
Step 303, adjusting the resolution of the second initial application interface to a second target resolution, and/or converting the data format of the second initial application interface into a second target format to obtain a second target application interface.
After the mobile terminal acquires the second initial application interface displayed by the second display screen, the resolution of the second initial application interface can be adjusted to the second target resolution, and/or the data format of the second initial application interface is converted into the second target format, so that the second target application interface is obtained. For example, after the mobile terminal acquires the second initial application interface, the resolution of the second initial application interface may be adjusted to the second target resolution, and the data format of the second initial application interface may be adjusted to the second target format, so as to obtain the second target application interface.
In the embodiment of the present application, for a scenario in which the mobile terminal acquires the second initial application interface, the mobile terminal may directly adjust the resolution of the second initial application interface, and/or convert the data format of the second initial application interface. And obtaining a second target application interface by using the second target format as the data format of the second initial application interface.
For a scenario in which the mobile terminal obtains layer source data corresponding to the second initial application interface, the mobile terminal may first obtain a second initial layer based on the second target resolution and the layer source data corresponding to the second initial application interface by drawing, and then may convert the data format of the second initial layer into a second target format to obtain a second target application interface.
Wherein the second target resolution may be a resolution close to the resolution of the projection device, which is pre-stored in the mobile terminal. Therefore, the second target application interface can be ensured to be highly adaptive to the second projection device, and the projection display effect of the second projection device can be ensured.
Alternatively, the second target resolution is the resolution of the second projection device. Therefore, the second target application interface sent by the mobile terminal to the second projection device can be ensured to be matched with the second projection device, and the projection display effect of the second projection device can be ensured.
Optionally, for a scene in which the second target resolution is the resolution of the second projection device, the second projection device may report the device information to the mobile terminal after accessing the second interface. Accordingly, the mobile terminal can obtain the device information. The device information may include a second projection device resolution. The device information may also include a model and a frame rate of the second projection device, and so on.
In this embodiment, the second target format is a data display format of the second projection device. Since the projection device generally receives data through a High Definition Multimedia Interface (HDMI), the first target format is an HDMI format. It follows that the first object format and the second object format may be identical.
Optionally, the signal converter of the mobile terminal may be further connected to the second interface. For the scenario that the processor of the mobile terminal directly acquires the second initial application interface, after acquiring the second initial application interface, the processor may send the second initial application interface to the signal converter. After the signal converter receives the second initial application interface, the data format of the second initial application interface can be converted from the MIPI format to the HDMI format.
For a scene that a processor of the mobile terminal obtains layer source data corresponding to the second initial application interface, after the processor draws a second initial layer based on the layer source data and the second target resolution of the second initial application interface, the processor may send the second initial layer to the signal converter, so that the signal converter converts the data format of the second initial layer from the MIPI format to the HDMI format, thereby obtaining the second target application interface.
Alternatively, the signal converter connected to the second interface may be different from the signal converter connected to the first interface. That is, the mobile terminal may include one signal converter corresponding to each interface. In this case, the drive codes of the plurality of signal converters may be different, and the drive codes may be recorded with addresses of the signal converters.
Optionally, for a scenario in which the mobile terminal is connected to two second projection devices (i.e., the second initial application interface includes a main interface and a floating interface), the second target application interface may include: a third sub-target application interface and a fourth sub-target application interface. Wherein the third sub-target application interface is available based on a third sub-initial application interface (e.g., home interface) of the second initial application interface, and the fourth sub-target application interface is available based on a fourth sub-initial application interface (e.g., hover interface) of the second initial application interface.
For example, the mobile terminal may adjust the resolution of the main interface of the second initial application interface to the second target resolution, and/or adjust the data format of the main interface to the second target format, so as to obtain the third sub-target application interface. The mobile terminal may adjust the resolution of the floating interface of the second initial application interface to the second target resolution, and/or adjust the data format of the floating interface to the second target format, so as to obtain the fourth sub-target application interface.
Optionally, for a scene in which the mobile terminal is connected to the two second projection devices, in the process of converting the data format of the main interface and the data format of the floating interface of the second initial application interface by the mobile terminal, different signal converters may be controlled to respectively convert the data formats of the main interface and the floating interface.
In a scenario where the first initial application interface and the second initial application interface both include a main interface and a floating interface, the mobile terminal may include: four signal converters, and the driving codes of the four signal converters may be different. Each of the four signal converters may be connected to one interface.
Step 304, sending the first target application interface to the first projection device.
After the mobile terminal obtains the first target application interface, the first target application interface can be sent to the first projection device for projection display of the first projection device.
For a scenario in which the first initial application interface includes a first sub-initial application interface (e.g., a main interface of the first initial application interface) and a second sub-initial application interface (e.g., a floating interface of the first initial application interface), that is, a scenario in which the first target application interface includes a first sub-target application interface and a second sub-target application interface, the mobile terminal may send the first sub-target application interface to one of the two first projection devices for projection display by the one first projection device. And the mobile terminal can also send the second sub-target application interface to the other first projection equipment in the two first projection equipment for projection display by the other first projection equipment.
Step 305, sending the second target application interface to the second projection device.
After the mobile terminal obtains the second target application interface, the second target application interface can be sent to the second projection device for projection display by the second projection device.
For a scenario in which the second initial application interface includes a third sub-initial application interface (e.g., the main interface of the second initial application interface) main interface and a fourth sub-initial application interface (e.g., the floating interface of the second initial application interface), that is, a scenario in which the second target application interface includes a third sub-target application interface and a fourth sub-target application interface, the mobile terminal may send the third sub-target application interface to one of the two second projection devices for projection display by the one second projection device. And the mobile terminal can also send the fourth sub-target application interface to the other second projection device of the two second projection devices for projection display by the other second projection device.
According to the above description, the mobile terminal may adjust the resolution of the application interface displayed thereon, convert the data format, and then respectively send the data format to the first projection device and the second projection device, so that the first projection device and the second projection device perform projection display. The mobile terminal can display the application interfaces displayed on different display screens through the plurality of projection devices, and projection display modes are effectively enriched.
In the following, taking the mobile terminal including the first display screen and the second display screen of the opposing device as an example, several optional implementations of the first target application interface and the second target application interface are described in the form of the accompanying drawings:
fig. 9 is a schematic diagram of a projection display of a projection apparatus provided in an embodiment of the present application. As shown in fig. 9, the first projection device 20 and the second projection device 30 may be disposed on the same support 40, the first projection device 20 may include a first projection lens 20a, and the second projection device 30 may include a second projection lens 30 a. As can be seen from fig. 9, the projection direction X of the first projection device 10 and the projection direction Y of the second projection device 20 may be different, and accordingly, the projection areas of the first projection device 20 and the second projection device 30 may be different. Referring to fig. 9, the projection direction X of the first projection device 20 and the projection direction Y of the second projection device 30 may intersect, for example, may be perpendicular.
The stand 40 may be placed on a table top M, the projection area of the first projection device 20 may be a partial area on the table top M, and the projection area of the second projection device 30 may be a partial area on the wall surface N.
Assuming that the initial application interfaces displayed by the first display screen and the second display screen of the mobile terminal are shown in fig. 3, after the mobile terminal 00 shown in fig. 3 is connected to the first projection device 20 and the second projection device 30, referring to fig. 9, the projection area of the first projection device 20 in the desktop M may display a first target application interface having the same application content as the first initial application interface, and the projection area of the second projection device 30 in the wall N may display a second target application interface having the same application content as the second initial application interface. That is, the projection area of the first projection device 20 may display the learning interface displayed by the first display screen, and the projection area of the second projection device 30 may display the reading interface displayed by the second display screen.
Fig. 10 is a schematic diagram of an application interface displayed on a display screen of another mobile terminal according to an embodiment of the present application. As can be seen from fig. 10, the first initial application interface displayed on the first display screen 01 is the same as the second initial application interface displayed on the second display screen 02.
Accordingly, when the first projection device and the second projection device are connected to the mobile terminal 00 shown in fig. 10, the projection screen shown in fig. 11 can be displayed. As can be seen from fig. 11, the application content of the first target application interface displayed in the projection area of the first projection device 20 in the desktop M is the same as the application content of the second target application interface displayed in the projection area of the second projection device 30 in the wall surface N.
Fig. 12 is a schematic diagram of an application interface of a display screen of a mobile terminal according to another embodiment of the present application, and as can be seen from fig. 12, a first initial application interface displayed on the first display screen 01 of the mobile terminal 00 may include: the main interface and the suspension interface which is displayed above the main interface in an overlapped mode.
In this case, the mobile terminal may be connected with two first projection devices, and the projection directions of the two first projection devices may intersect or be parallel. For example, referring to fig. 13, the projection directions of the two first projections 20 may be perpendicular. The projection direction of one of the two first projection devices 20 is different from the projection direction of the second projection device 30, and the projection direction of the other first projection device 20 is the same as the projection direction of the second projection device 30.
As shown in fig. 13, after the mobile terminal is connected to the two first projection devices 20 and the second projection device 30, the projection screen shown in fig. 13 can be displayed. As can be seen from fig. 13, the projection area of one first projection device 20 in the desktop M displays a first sub-target application interface having the same application content as the main interface of the first initial application interface.
The projection area of the other first projection device 20 in the wall surface M (i.e. the part of the area near the bracket 40 in fig. 11) displays a second sub-target application interface with the same application content as the floating interface of the first initial application interface.
It should be noted that, for a scenario in which the mobile terminal obtains the first target application interface based on the layer source data corresponding to the first initial application interface, and a scenario in which the mobile terminal obtains the second target application interface based on the layer source data corresponding to the second initial application interface, a developer may set a relevant parameter in a surfeflinger of the mobile terminal before the mobile terminal leaves a factory, so that the surfeflinger may draw different layers based on different layer source data at the same time. Wherein, the surfefringer refers to a process running in a processor of the mobile terminal.
It should be further noted that, the order of the steps of the projection method of the mobile terminal shown in the foregoing embodiment may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. For example, step 302 and step 303 may be performed simultaneously, and step 304 and step 305 may be performed simultaneously. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.
In summary, the embodiment of the present application provides a projection method of a mobile terminal, where the mobile terminal has a first display screen and a second display screen, and the mobile terminal may be connected to a first projection device and a second projection device. The mobile terminal can respectively send the target application interfaces to the first projection device and the second projection device so as to enable the projection devices to perform projection display, and the target application interfaces are obtained based on the first initial application interfaces displayed by the first display screen or the second initial application interfaces displayed by the first display screen and the second display screen. Namely, the mobile terminal can perform projection display on the application interfaces displayed on different display screens through a plurality of projection devices, so that the projection display modes are effectively enriched.
In the following embodiments, a first target application interface and a second target application interface are both obtained based on a first initial application interface displayed by a first display screen of a mobile terminal, and the first initial application interface includes a main interface and a floating interface.
Fig. 14 is a flowchart of a projection method of a mobile terminal according to an embodiment of the present disclosure. The method may be applied to a mobile terminal, such as the mobile terminals shown in fig. 5 to 7. The mobile terminal may include: the display device comprises a first display screen and a second display screen. Referring to fig. 14, the method may include:
step 401, acquiring a first display screen to display a first initial application interface.
After the mobile terminal is determined to be connected with the first projection device and the second projection device, a first initial application interface displayed by the first display screen can be acquired.
The first initial application interface can comprise a main interface and a floating interface which is superposed and displayed on the main interface. The mobile terminal determines a process of connecting with the first projection device and the second projection device, which may refer to step 301 or step 302, and is not described herein again in this embodiment of the present application.
Optionally, the mobile terminal may directly obtain the first initial application interface displayed by the first display screen. Or, the mobile terminal may obtain the layer source data corresponding to the first initial application interface.
Step 402, adjusting the resolution of the main interface included in the first initial application interface to a first target resolution, and/or converting the data format of the main interface into a first target format to obtain a first target application interface.
After the mobile terminal acquires the first initial application interface displayed by the first display screen, the resolution of a main interface included in the first initial application interface can be adjusted to be a first target resolution, and/or the data format of the main interface is converted into a first target format, so that the first target application interface is obtained. For example, the mobile terminal may adjust the resolution of the main interface to a first target resolution, and may adjust the data format of the main interface to a first target format, thereby obtaining a first target application interface.
The first target format is a data display format of the first projection device, for example, the first target format is an HDMI format. The first target resolution may be determined by a developer based on resolutions of the plurality of projection devices and written to the mobile terminal before the mobile terminal is shipped. For example, the first target resolution may be a resolution that occurs a greatest number of times among a plurality of resolutions of a plurality of projection devices. Therefore, the first target application interface can be ensured to be high in adaptation degree with the first projection device, and the projection display effect of the first projection device can be ensured. Alternatively, the first target resolution is the resolution of the first projection device. Therefore, the first target application interface sent by the mobile terminal to the first projection device can be ensured to be adapted to the first projection device, and the projection display effect of the first projection device can be ensured.
Optionally, the implementation process of adjusting the resolution of the main interface and/or converting the data format of the main interface by the mobile terminal may refer to the corresponding implementation process in step 303 or step 304, which is not described herein again in this embodiment of the present application.
Step 403, adjusting the resolution of the floating interface included in the first initial application interface to a second target resolution, and/or converting the data format of the second initial application interface into a second target format to obtain a second target application interface.
After the mobile terminal acquires the first initial application interface displayed by the first display screen, the resolution of the floating interface included in the first initial application interface can be adjusted to be the second target resolution, and/or the data format of the floating interface is converted into the second target format, so that the second target application interface is obtained. For example, the mobile terminal may adjust the resolution of the main interface to the second target resolution, and may adjust the data format of the main interface to the second target format, so as to obtain the second target application interface.
The second target format is a data display format of the second projection device, for example, the second target format is an HDMI format. The second target resolution may be determined by a developer based on resolutions of the plurality of projection devices and written to the mobile terminal before the mobile terminal is shipped. For example, the second target resolution may be a resolution that occurs a greatest number of times among the plurality of resolutions of the plurality of projection devices. Therefore, the second target application interface can be ensured to be highly adaptive to the second projection device, and the projection display effect of the second projection device can be ensured.
Alternatively, the second target resolution is the resolution of the second projection device. Therefore, the second target application interface sent by the mobile terminal to the second projection device can be ensured to be matched with the second projection device, and the projection display effect of the second projection device can be ensured.
Optionally, the implementation process of adjusting the resolution of the floating interface and/or converting the data format of the floating interface by the mobile terminal may refer to the corresponding implementation process in step 303 or step 304, which is not described herein again in this embodiment of the present application.
Step 404, sending the first target application interface to the first projection device.
After obtaining the first target application interface, the mobile terminal may send the first target application interface to the first projection device, so that the first projection device may perform projection display on the first target application interface.
Step 405, sending the second target application interface to the second projection device.
After obtaining the second target application interface, the mobile terminal may send the first target application interface to the second projection device, so that the first projection device may perform projection display on the second target application interface.
For example, assuming that the first initial application interface displayed on the first display screen of the mobile terminal is as shown in fig. 12, after the mobile terminal is connected to the first projection device and the second projection device, the projection screen shown in fig. 15 may be displayed. As shown in fig. 15, the projection area of the first projection device 20 in the desktop M displays the first target application interface with the same application content as the main interface of the first initial application interface. The projection area of the second projection device 30 in the wall surface N displays a second target application interface having the same application content as the floating interface of the first initial application interface.
According to the above description, the mobile terminal may send the first target application interface obtained from the main interface based on the first initial application interface to the first projection device, so that the first projection device may perform projection display. And the mobile terminal can also send a second target application interface obtained based on the floating interface of the first initial application interface to second projection equipment for projection display by the second projection equipment. Therefore, the mobile terminal can separately project the main interface and the suspension interface, and therefore the projection display mode is enriched. In addition, the main interface and the suspension interface can be separately projected and displayed, so that the shielding of the suspension interface on the main interface is avoided, and the display effect of the main interface and the suspension interface is improved.
It should be noted that, in the above embodiment, the first initial application interface displayed on the first display screen includes two sub initial application interfaces displayed in an overlapping manner, that is, a main interface and a floating interface. In practical implementation, the first initial application interface may further include two sub-initial application interfaces displayed after the screen is split. Alternatively, the first initial application interface may include only one initial application interface. The embodiment of the present application does not limit this.
For a scenario that the first initial application interface may only include one sub-initial application interface, in an optional implementation manner, the mobile terminal obtains a first target application interface and a second target application interface based on the first initial application interface, and respectively sends the first target application interface and the second target application interface to the first projection device and the second projection device. The first target application interface is obtained by adjusting the resolution of the first initial application interface to a first target resolution and/or converting the data format of the first initial application interface into a first target format. The second target application interface is obtained by adjusting the resolution of the first initial application interface to a second target resolution and/or converting the data format of the first initial application interface into a second target format. Correspondingly, the first projection device and the second projection device project the same displayed picture.
In another optional implementation manner, the mobile terminal obtains the first target application interface only based on the first initial application interface, and sends the first target application interface to the first projection device without generating the second target application interface. At this time, the second projection device may project and display the preset application interface. The preset application interface may be pre-stored in the second projection device, for example, the preset application interface may be an application interface including a clock for indicating the current time. That is, the second projection device does not receive the second target application interface sent by the mobile terminal under the condition, that is, the second projection device is in a standby state, and at this time, the second projection device may display the preset application interface.
It should be further noted that, the order of the steps of the projection method of the mobile terminal provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. For example, step 402 and step 403 may be performed synchronously, and step 404 and step 405 may also be performed synchronously. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.

The mobile terminal can send the first target application interface obtained from the main interface based on the first initial application interface to the first projection device for projection display by the first projection device. And the mobile terminal can also send a second target application interface obtained based on the floating interface of the first initial application interface to second projection equipment for projection display by the second projection equipment. Namely, the mobile terminal can separately perform projection display on the main interface and the floating interface included in the same initial application interface through a plurality of projection devices, thereby enriching the projection display mode.
