[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] During the speech, if you want to display a certain piece of information in the client on the large screen, whether it is copied from the client with a USB flash drive, transmitted through a communication software, or through a screen mirroring software, there are some problems, such as low efficiency, privacy leakage, etc. Therefore, this application provides a file display method based on a screen mirroring device. By entering the information to be retrieved on the large screen end, the corresponding file can be found from the client and displayed, reducing the risk of privacy leakage of the client.

[0039] See Figure 1 As shown, an embodiment of the present invention discloses a file display method based on a screen mirroring device, which is applied to the large screen end and includes:

[0040] Step S11: Write the first large screen information into the screen mirroring device connected to the large screen end, and broadcast the second large screen information, so that the screen mirroring device can establish a connection with the large screen end based on the first large screen information and the second large screen information, and after connecting the screen mirroring device to the client, establish a connection between the client and the large screen end based on the screen mirroring device.

[0041] In this embodiment, a service software is pre-installed on the large screen end. This service software is mainly responsible for screen mirroring device pairing, receiving the index database sent by the screen mirroring device, and interacting with the user. Specifically, connect the screen mirroring device to the large screen end and start the pre-installed service software. Write the first large screen information into the screen mirroring device connected to the large screen end through the service software, where the large screen information includes the large screen device number; and use the UDP (User Datagram Protocol) network transmission method to broadcast messages carrying the second large screen information regularly, so that all screen mirroring devices in the same network segment as the large screen end will receive the second large screen information. However, since only the screen mirroring device connected to the large screen end has written the first large screen information, the screen mirroring device connected to the large screen end can match the second large screen information based on the first large screen information, and establish a connection with the large screen end after successful matching, and then traverse the files in the large screen end to generate a first preset file index database corresponding to the large screen end for recording the correspondence between the file name and the file path, and store the first preset file index database in the large screen end. Other screen mirroring devices in the same network segment cannot establish a connection with the large screen end because they have not written the first large screen information.

[0042] In this embodiment, after establishing a connection between the screen mirroring device and the large screen terminal, the screen mirroring device is connected to the client. A storage partition selection interface is popped up through the client, and the retrievable storage partition in the client is determined based on the storage partition selection instruction obtained from the interface on the storage partition selection interface. Then, confirmation connection information is obtained to establish a connection between the client and the large screen terminal through the screen mirroring device based on the confirmation connection information. It can be understood that after the screen mirroring device is connected to the client, a storage partition selection interface will automatically pop up on the client. Among them, the storage partition selection interface is used to select the retrievable storage partition or non-retrievable storage partition in the client, and by default, all storage partitions in the client are selected as retrievable storage partitions on the storage partition selection interface; after determining the retrievable storage partition, the click operation of the user on the confirmation connection button is obtained to obtain the confirmation connection information, so as to establish a connection between the client and the large screen terminal through the screen mirroring device based on the confirmation connection information. It should be noted that the storage partition selection interface can also be further divided into the selection of a certain folder or a certain file in the retrievable storage partition.

[0043] In this embodiment, after establishing a connection between the client and the large screen terminal based on the screen mirroring device, the files in the retrievable storage partition are traversed through the screen mirroring device connected to the client to generate a second preset file index database corresponding to the client for recording the correspondence between the file name and the file path, and the second preset file index database is encrypted and transmitted to the large screen terminal by using the UDP network transmission method, so that the large screen terminal can decrypt and save the encrypted second preset file index database. In this way, since only the file index database for recording the correspondence between the file name and the file path is transmitted, the subsequent file retrieval speed can be greatly accelerated; and by encrypting and transmitting the file index database, data privacy can be protected from being leaked.

[0044] Step S12: After establishing the connection between the client and the large screen terminal, obtain the to-be-retrieved file information through the file retrieval interface, match the target file name corresponding to the to-be-retrieved file information from the preset file index database corresponding to the device information of the device to which the file belongs in the to-be-retrieved file information, and determine the file path corresponding to the target file name.

[0045] In this embodiment, after establishing a connection between the client and the large screen terminal based on the screen mirroring device, and the large screen terminal receives the second preset file index database corresponding to the client, if the user needs to obtain the file materials in the client connected to the screen mirroring device, the user can click the floating search button on the large screen terminal. That is, the large screen terminal will correspondingly obtain the click operation on the floating search button, and then a file search interface will pop up on the current display screen of the large screen terminal, and the user inputted file information to be retrieved will be obtained through the file search interface. Among them, the file information to be retrieved includes the device information to which the file belongs, the file type, and the file keyword; the device information to which the file belongs is the client or the large screen terminal.

[0046] Further, after obtaining the file information to be retrieved including the device information to which the file belongs, the file type, and the file keyword, several file names corresponding to the file type and the file keyword are matched from the preset file index database corresponding to the device information to which the file belongs, and the file name list generated based on the several file names is displayed on the current display screen. Among them, if the device information to which the file belongs is the client, several file names corresponding to the file type and the file keyword are matched from the second preset file index database corresponding to the client; if the device information to which the file belongs is the large screen terminal, several file names corresponding to the file type and the file keyword are matched from the first preset file index database corresponding to the large screen terminal. Then, the file selection instruction for the file name list inputted by the user is obtained, the target file name is determined from the file name list based on the file selection instruction, and the file path corresponding to the target file name is matched from the preset file index database corresponding to the device information to which the file belongs.

[0047] Step S13: If the device information to which the file belongs is the client, the file path is sent to the screen mirroring device connected to the client, so that the screen mirroring device transfers the target file corresponding to the file path queried from the client to the large screen terminal, and the large screen terminal displays the target file.

[0048] In this embodiment, if the device information to which the file belongs is the client, the file path is sent to the screen mirroring device connected to the client, so that the screen mirroring device queries the target file corresponding to the file path from the client, and transfers the target file to the large screen terminal through the RUDP (Reliable User Datagram Protocol) network transmission method, and the large screen terminal displays the target file. If the device information to which the file belongs is the large screen terminal, the target file corresponding to the file path is queried from the large screen terminal, and the target file is displayed.

[0049] In this embodiment, displaying a target file may specifically include obtaining a file display method selected by a user and displaying the target file based on the file display method. The file display methods include displaying the file via an electronic whiteboard, displaying the file via a player, displaying the file via image processing software, and displaying the file via office software. The target file includes images, documents, and videos. It should be noted that the file display methods are not limited to the aforementioned methods and may also be displayed via other third-party tools or software.

[0050] It can be seen that this application opens the connection between the large screen and the client based on the screen sharing device, so that the user can enter the file information to be retrieved on the large screen, match the corresponding file name and file path from the pre-saved file index database, and then directly search for the corresponding file from the client based on the file path and display it on the large screen, which improves the efficiency of file acquisition, and can protect user privacy to a great extent, accurately find the files that the user wants to display, and the user does not need to remember the location where the file is stored, which improves the user experience.

[0051] See also Figure 2 As shown, an embodiment of the present invention discloses a file display method based on a same-screen device, which is applied to a large-screen terminal, including:

[0052] The pre-installed service software is started through the large-screen terminal, and the screen sharing device is connected to the large-screen terminal. The first large-screen information is written to the screen sharing device connected to the large-screen terminal through the started service software, and the second large-screen information is broadcasted to the outside at regular intervals, so that the screen sharing device connected to the large-screen terminal can match the second large-screen information based on the first large-screen information, and establish a connection with the large-screen terminal after the match is successful. Then, the files in the large-screen terminal are traversed to generate a first preset file index database corresponding to the large-screen terminal for recording the correspondence between file names and file paths, and the first preset file index database is stored in the large-screen terminal.

[0053] After establishing a connection between the screen-matching device and the large-screen end, the screen-matching device is connected to the client, and a storage partition selection interface is automatically popped up through the client. The retrievable storage partition or the non-retrievable storage partition in the client is determined based on the storage partition selection instruction obtained from the interface on the storage partition selection interface, and then the confirmation connection information input by the user is obtained to establish a connection between the client and the large-screen end through the screen-matching device based on the confirmation connection information. After establishing a connection between the client and the large-screen end based on the screen-matching device, the files in the retrievable storage partition are traversed through the screen-matching device connected to the client to generate a second preset file index database corresponding to the client for recording the correspondence between the file name and the file path, and the second preset file index database is transmitted to the large-screen end for storage.

[0054] After the large-screen terminal receives the second preset file index database corresponding to the client, if the user needs to obtain the file information in the client connected to the same-screen device, the user can click the translucent floating search button in the upper left corner of the large-screen terminal, that is, the large-screen terminal will correspondingly obtain the click operation on the floating search button, and then a file search interface will pop up on the current display screen of the large-screen terminal, wherein the file search interface includes a file search bar. Furthermore, the file search bar can obtain the device information of the file input by the user, such as the client or the large-screen terminal; and obtain the file type input by the user, such as pictures, audio, video and documents; at the same time, it can also obtain the file keywords input by the user through voice recognition or keyboard input, thereby obtaining the file information to be retrieved including the device information of the file, the file type and the file keyword.

[0055] Furthermore, after obtaining the file information to be retrieved, a plurality of file names corresponding to the file type and file keywords are matched from a preset file index database corresponding to the device information to which the file belongs, and a file name matching list generated based on the plurality of file names is displayed on the current display screen. A file selection instruction for the file name matching list input by the user is then obtained, and based on the file selection instruction, a target file name is determined from the file name matching list, and a file path corresponding to the target file name is matched from a preset file index database corresponding to the device information to which the file belongs. If the device information to which the file belongs is the client, the file path is sent to a screen sharing device connected to the client, so that the screen sharing device queries the client for the target file corresponding to the file path and transmits the target file to the large-screen terminal for display. If the device information to which the file belongs is the large-screen terminal, the target file corresponding to the file path is searched from the large-screen terminal and the target file is displayed. Displaying the target file includes displaying the target file by opening the file normally, displaying the target file by inserting the file into an electronic whiteboard, and displaying the target file by opening the folder to which the file belongs.

[0056] It can be seen that this application opens the connection between the large screen and the client based on the screen sharing device, so that the user can enter the file information to be retrieved on the large screen, match the corresponding file name and file path from the pre-saved file index database, and then directly search for the corresponding file from the client based on the file path and display it on the large screen, which improves the efficiency of file acquisition, and can protect user privacy to a great extent, accurately find the files that the user wants to display, and the user does not need to remember the location where the file is stored, which improves the user experience.
