Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a screen projection method according to an embodiment of the present invention, where the screen projection method is applied to a terminal, and the terminal includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like. As shown in fig. 2, the terminal 200 includes at least two display screens 210. As shown in fig. 1, the screen projection method mainly includes the following steps:
in this embodiment, the terminal is connected with the display device, the screen-projecting content or the file of the terminal can be projected to the display device for displaying, and the user can trigger the screen-projecting application by applying the screen-projecting operation to the terminal. The display device may be a display, a television, an advertisement screen, or other devices with a display function. The screen projection operation may be a click operation of a screen projection application identifier acting on the terminal, or may also be a preset trigger operation, for example, a sliding operation simultaneously acting on at least two display screens, or a voice wake-up screen projection application, and the like, without limitation.
The terminal and the display device both comply with a Miracast protocol, the Miracast protocol is a screen projection protocol based on wireless fidelity Direct (WiFi Direct), when the terminal and the display device are connected to the same WiFi, the terminal can be connected with the display device, screen projection content of the terminal, such as interface information of the terminal, pictures, videos or documents stored in the terminal, is sent to the display device, and the display device displays the screen projection content. Generally, the display size of the display screen of the terminal is relatively small, and the display size of the display device is relatively large. Therefore, the terminal sends the screen projection content to the display equipment to be amplified and displayed, and the user can watch the screen projection content more conveniently.
After receiving the screen projection operation, the terminal can be connected to display devices under the same WiFi, and the number of the display devices can be at least one. The terminal can be connected to all display devices under the same WiFi, or can be connected only to display devices that are not occupied by other terminals by projecting screens. And after receiving the screen projection operation, the terminal displays display equipment which can be used for screen projection.
before a terminal projects a screen to a display device, the terminal needs to determine the display device executing the display operation, i.e., a target screen projecting device. The terminal can take a certain display device connected to the terminal as the target display device, and the target screen projection content at the moment is a piece of screen projection content. If the number of the target display devices is two, the determined target screen projection content can be one or two, one same screen projection content can be projected to the two target display devices at the same time for display, and two different screen projection contents can be projected to the two target display devices respectively for display.
In addition, the terminal needs to determine screen projection content to be displayed, that is, target screen projection content, where the target screen projection content may include screen projection content of N display screens of the at least two display screens, where N is an integer greater than 1. In specific implementation, the terminal can directly synthesize the interface information of the N preselected display screens into the target screen projection content, and can also synthesize the interface information of the N display screens selected by the user into the target screen projection content.
Optionally, the screen projection operation is a touch operation simultaneously acting on N display screens of the at least two display screens;
the target screen projection content comprises screen projection contents of N display screens acted by the screen projection operation.
And if the screen projection operation triggered by the user is touch operation which simultaneously acts on the N display screens of the terminal, the synthesized target screen projection content can be the screen projection content of the N display screens correspondingly. Therefore, the operation that the user selects a part of the display screens from at least two display screens to project the screens can be omitted.
103, sending target screen projection content to the target display device, wherein the target screen projection content includes screen projection content of N display screens of the at least two display screens, and N is an integer greater than 1.
And after determining the target display equipment according to the steps, the terminal can send the target screen projection content to the target display equipment, and the target display equipment displays the received target screen projection content. Thus, the user can watch the screen projection content of the terminal on the display device.
After the terminal projects the target screen projection content to the target display equipment, if the interface information of the terminal is continuously operated to change, the target screen projection content displayed on the target display equipment can also be changed accordingly. Of course, if the user needs to lock the content displayed on the target display device to the current target screen-casting content for static or dynamic playing, the display may also be locked through a related locking operation, which is not limited.
In the screen projection method provided by the embodiment of the invention, for a terminal provided with at least two display screens, at least one display device which can be used for screen projection is displayed on the terminal, and after a target display device is determined, the target screen projection content comprising the screen projection contents of the N display screens can be sent to the determined target display device so as to be displayed on the target display device, so that the purpose of projecting the screen projection contents of the at least two display screens of the terminal onto the display device for display can be realized, and the screen projection scheme of the terminal is optimized.
Referring to fig. 3, fig. 3 is a schematic flow chart of another screen projection method according to an embodiment of the present invention. The screen projection method provided by the embodiment is different from the above embodiments in that the determination operation of the target screen projection content is further defined. As shown in fig. 3, the screen projection method mainly includes:
301, displaying at least one display device available for screen projection under the condition of receiving screen projection operation;
and after receiving the screen projection operation, the terminal is connected to at least one display device under the same WiFi and displays the at least one display device. The specific implementation process of the terminal receiving the screen projection operation and connecting the at least one display device may refer to the specific implementation process of step 101, which is not described in detail.
when the terminal determines the target screen projection content, the terminal first determines N display screens participating in screen projection operation in at least two display screens of the terminal, and determines a synthesis mode of the screen projection content of the N display screens, namely, determines a configuration scheme of the screen projection content of the N display screens.
At least one synthesis mode can be stored in the terminal in advance, and the synthesis mode comprises a display screen participating in synthesis and a configuration scheme of synthesized screen projection content. And the terminal obtains at least one synthesis mode according to the display screens possibly participating in combination and the arrangement scheme of the screen projection contents of the display screens participating in combination. After the user triggers the screen-projecting operation, the terminal can display the at least one synthesis mode, the user selects the at least one synthesis mode from the at least one synthesis mode, and the synthesis mode selected by the user is determined as the target synthesis mode. The user can select the target combination mode by applying a click operation or a slide operation or the like.
And 303, synthesizing the screen projection contents of the N display screens according to the target synthesis mode to obtain target screen projection contents.
After the terminal determines the target synthesis mode according to the steps, screen projection contents of the N display screens can be synthesized according to the target synthesis mode, and the formed new screen projection contents are the target screen projection contents.
Of course, in other embodiments, the terminal may also send the target composition mode to the display device, and the display device combines and displays the screen projection contents of the N display screens according to the target composition mode.
and 305, sending the target screen projection content to the target display equipment.
The terminal determines target screen projection content and target display equipment, then the target screen projection content is sent to the target display equipment, and the target display equipment is used for screen projection display. The sequence of the target screen projection content and the internal display equipment determined by the terminal can be exchanged without limitation. The specific implementation processes of the terminal determining the target display device and sending the target screen projection content may refer to the specific implementation processes of steps 102 and 103, which are not described in detail herein.
In one embodiment, as shown in fig. 2, the terminal may include a first display (e.g., a shown in fig. 2) and a second display (e.g., B shown in fig. 2);
the target synthesis mode comprises at least one of the following modes: a first synthesis mode, a second synthesis mode, a third synthesis mode and a fourth synthesis mode;
the first synthesis mode is used for indicating that the screen projection content of the first display screen and the screen projection content of the second display screen are transversely synthesized, and the screen projection content of the first display screen is positioned on the first side of the screen projection content of the second display screen;
the second synthesis mode is used for indicating that the screen projection content of the first display screen and the screen projection content of the second display screen are transversely synthesized, and the screen projection content of the first display screen is positioned on the second side of the screen projection content of the second display screen;
the third synthesis mode is used for indicating that the screen projection content of the first display screen and the screen projection content of the second display screen are longitudinally synthesized, and the screen projection content of the first display screen is positioned on a third side of the screen projection content of the second display screen;
the fourth synthesis mode is used for indicating that the screen projection content of the first display screen and the screen projection content of the second display screen are synthesized longitudinally, and the screen projection content of the first display screen is located on the fourth side of the screen projection content of the second display screen.
Specifically, if the terminal includes a first display A and a second display B, the first to fourth combining manners provided by the terminal may be, in order, A | B, B | A,
Schematic diagrams of displaying the screen-shot content corresponding to the composition modes on the display device may be sequentially shown in fig. 4a to 4 d. Of course, the terminal may also expand more combination schemes by adjusting the display ratio of at least two display screens, irregular arrangement schemes, and the like, without limitation.
Certainly, in other embodiments, the user may also temporarily customize the interface combination scheme, or customize the interface combination scheme in advance and store the interface combination scheme for subsequent screen projection operation selection, so as to further expand screen projection options and facilitate the use of the user.
According to the screen projection method provided by the embodiment of the invention, the terminal is selected by the user by displaying the multiple interface combination schemes and the identifier of the display equipment, so that the screen projection scheme of the terminal is simplified, and the convenience of screen projection operation is improved. The specific implementation process of the screen projection method provided by the embodiment of the present invention may refer to the specific implementation process of the screen projection method provided by the embodiment shown in fig. 1, and is not described in detail here.
Further, the determining the target synthesis method in step 302 may include:
selecting the target synthesis mode from the displayed at least two synthesis modes; or
Receiving a first touch operation on at least one of the at least two display screens, and determining a synthetic mode corresponding to an operation parameter of the first touch operation as the target synthetic mode; or
And under the condition that the screen projection operation is a second touch operation acting on N display screens of the at least two display screens, determining a synthetic mode corresponding to the operation parameters of the screen projection operation as the target synthetic mode.
In this embodiment, the specific determination process for the target synthesis mode is further expanded, and the three listed embodiments are further defined below.
In a specific embodiment, at least two synthesis modes are stored in the terminal in advance, and each synthesis mode is used for indicating the display screen participating in screen projection and the arrangement mode of the screen projection content of the display screen participating in screen projection. The terminal can display the at least two synthesis modes after detecting that the screen projection operation is triggered by the user, and the user selects one synthesis mode as a target synthesis mode from the displayed at least two synthesis modes by applying touch operation such as click and sliding and a voice control mode. The determination scheme of the target synthesis mode is simple and clear, and the operation is convenient.
In another specific embodiment, the user may determine the target composition manner by applying the first touch operation on the terminal. After the screen projection operation is triggered, the user can select to apply a first touch operation on at least one of the at least two display screens. And the terminal determines a synthetic mode corresponding to the operating parameter of the first touch operation according to the operating parameter of the first touch operation, namely the target synthetic mode.
Specifically, the first touch operation may be a touch operation acting on a certain display screen, and then the screen projection content of the display screen may be directly used as the target screen projection content, or the screen projection content of the display screen may be used as the main screen projection content, the main screen projection content may be used as the screen projection content at the leftmost end or the upper end or as the center screen projection, and the screen projection contents of other display screens may be correspondingly arranged in sequence or arranged in a surrounding manner, etc.
In addition, the first touch operation may also be a touch operation applied to the N two display screens, and it is determined that the screen-projected contents of the N display screens all participate in the composition. At this time, the corresponding synthesis mode is determined according to the difference of the sequence, the touch track, the touch type and the like of the first touch operation acting on different display screens.
According to the scheme for determining the target synthesis mode, the terminal can determine the target synthesis mode selected by the user by collecting the operation parameters of the first touch operation applied by the user, and the operation is simple and rapid.
In another embodiment, the screen projection operation performed by the user on the terminal is a second touch operation, and the second touch operation is simultaneously performed on N display screens of the at least two display screens. The second touch operation can be used as a screen projection starting operation, and a user can determine a target synthesis mode of target screen projection content. And the user applies the second touch operation on each display screen of the N display screens at the same time, and the determined target synthesis modes are different according to the difference of the operation parameters such as the sliding direction, the sliding track and the like of the second touch operation.
Specifically, the terminal is set as the terminal shown in fig. 2, and includes a first display screen a and a second display screen B, and a specific process of determining the target synthesis mode according to the operation parameter of the second touch operation may be as shown in fig. 5a to 5 d. As shown in fig. 5a, if the direction of the sliding operation applied to the first display screen is laterally leftward, and the direction of the sliding operation applied to the second display screen is laterally rightward, the display effect of the target screen projection content on the target display device is as shown in fig. 4 a. As shown in fig. 5b, the direction of the sliding operation on the first display screen is horizontal to the right, and the direction of the sliding operation on the second display screen is horizontal to the left, so that the display effect of the target screen projection content on the target display device is as shown in fig. 4 b. As shown in fig. 5c, if the direction of the sliding operation on the first display screen is vertical upward, and the direction of the sliding operation on the second display screen is vertical downward, the display effect of the target screen projection content on the target display device is as shown in fig. 4 c. As shown in fig. 5d, if the direction of the sliding operation on the first display screen is vertically downward and the direction of the sliding operation on the second display screen is vertically upward, the display effect of the target screen projection content on the target display device is as shown in fig. 4 d.
In the embodiment, the terminal can start the screen projection operation and determine the target synthesis mode only through one touch operation applied by the user, so that the calculation process of the terminal is saved, and the user operation is further simplified.
In another embodiment, the step of determining the target synthesis method as described in step 302 further includes:
and determining the target synthesis mode under the condition that at least one display screen is projected to the target display equipment in the at least two display screens.
Considering that the terminal has at least two display screens, there may be a screen projection scheme that a user needs to add or switch after projecting screen projection content of at least one display screen onto one display device. After receiving the screen projection operation, the terminal displays at least one display device available for screen projection, where the at least one display device may have been used to perform a previous screen projection operation of the terminal, and as shown in fig. 6, the terminal marks and displays the occupied display device to display the previous screen projection state to the user.
If the terminal determines that the screen projection content of one display interface is projected to one display device, the terminal can operate according to the added or switched screen projection scheme. Specifically, the first display screen is set to perform screen projection operation, and the display device projected by the first display screen is defined as occupied display device.
The user selects one display device from at least one display device displayed by the terminal as a target display device. If the selected target display device is an occupied display device, screen projection contents of the first display screen and the second display screen can be combined into new screen projection contents to serve as the target screen projection contents, and the screen projection contents of the first display screen which are already displayed by the occupied display device are switched into recombined target screen projection contents. If the selected target display device is not the occupied display device, the screen projection content of the second display screen can be directly projected to the target display device as the target screen projection content to be displayed, and at the moment, the occupied display device can continuously display the screen projection content of the first display screen.
Of course, in other embodiments, when the terminal determines the target display device, the terminal may also determine the screen-projected content of the second display screen as the target screen-projected content, screen-project the screen-projected content of the second display screen onto the occupied display device, and close the operation of screen-projecting the screen-projected content of the first display screen onto the occupied display device. In addition, when the terminal projects the target screen projection content to the target display device which is not the occupied display device, the operation of projecting the first display screen to the occupied display device can be also closed, and the method is not limited.
In other embodiments, the user may mark the visibility of the projected content, which may include visible and invisible types, in consideration of the privacy of the partial projected content on the terminal. Therefore, when the terminal performs screen projection, the screen projection content marked as visible can be directly sent to the display equipment to be displayed, and the screen projection content marked as invisible can not be sent to the display equipment to be displayed, so that the information privacy and the safety of a user are improved. Of course, the screen projection method provided in this embodiment may also be extended to a scheme of displaying the screen projection contents of multiple terminals on a display device in a combined manner, which is not limited herein.
