Problems solved by technology

[0003] In the above projection display method, the file content displayed on the client display screen of the projector is the same as that displayed on the projection display screen; when viewing other file content, it is necessary to switch the display file content through the client display screen, the client display screen and the projection display screen The projection screen displays the new file content at the same time according to the switched file content; however, in some occasions, when the user displays the file content on the projection screen, he needs to obtain other required file content from the projector. At this time, the user operates the client display screen will cause the projection screens to switch at the same time, which affects the work efficiency and user experience of the projector; in addition, when the user performs projection on the current projection screen on the projector, the user cannot view other file content on the client screen, and also It is impossible to prepare the content displayed next time on the projection screen in advance. To switch the projected file content, you need to wait until the current projection ends or the current projection is interrupted, which also affects the work efficiency and user experience of the projector.

Embodiment 1

[0050] In this embodiment, the display screen for displaying file content includes a projection display screen that works through the projection lamp of the projector, a client display screen of the projector itself, and a third display screen through wired or wireless connection;

[0051]The content of the file to be displayed on different display screens can be the same or different, and the present embodiment reads and outputs the file content through the display process configured for each display screen; the present embodiment The content of the file is explained by taking the video file as an example;

[0052] In this embodiment, the display process is run on the terminal of the projector or the third display screen,

[0053] When displaying the content of the file, it is first necessary to generate a corresponding access path to read the file according to the storage path of the file content;

[0054] The display process obtains the access path according to the content...

Embodiment 2

[0057] In this embodiment, the display control is performed on the client display screen of the projector or the terminal of the third display screen, which is equivalent to displaying the control interface on the client display screen of the projector or the third-party display screen of the terminal;

[0058] The display process of present embodiment configuration client display screen is front-end process (PFront), and present embodiment controls client display screen to display main menu desktop by PFront;

[0059] The display process of present embodiment configuration projection display screen is back-end process (PBackground), present embodiment carries out projection display screen display video resource by PBackground; Video resource can be the video resource of high-definition multimedia interface (HDMI) or other format, The method for reading and outputting video resources is a conventional technical means for those skilled in the art.

[0060] The third display scr...

Embodiment 3

[0062] In this embodiment, the multi-screen display of the mobile terminal is taken as an example for clear and detailed description. The mobile terminal establishes a communication connection through a wireless connection, which may be a communication connection established based on WIFI, or a communication connection established through Bluetooth, infrared, etc. image 3 It is the method flowchart of the third embodiment of the present invention, as image 3 shown, including:

[0063] Step 300, turn on the projector and perform projection display;

[0064] Step 301, configure the display process of multi-screen display by setting the mobile terminal;

[0065] Step 302, the mobile terminal controls the display content of each display screen through the display process;

[0066] It should be noted that the content of the displayed file is controlled through the display process of this embodiment. When switching the content of the displayed file, for example, when adjusting t...

Abstract

The application discloses a method and device for implementing multi-screen display. The method comprises the steps of: by configuring a display process to each display screen in advance according to a corresponding relationship, respectively reading file contents which need to be displayed by each display screen; and outputting the read file contents which need to be displayed to the corresponding display screens to carry out display. According to the invention, by controlling the contents displayed by different display screens in different display processes, display of different display screen on different file contents is implemented; and further, a case of implementing control on the displayed file contents by the display processes can be implemented by remote operation, and a plurality of display processes respectively carry out control on the contents displayed by the display screens, and thus, when the display screens in the display processes are subjected to file content switching, file content display of other display screens cannot be influenced, so that time consumption for carrying out file content switching is reduced, and use experience of user projection is improved.

Description

technical field [0001] The present application relates to projection display technology, in particular to a method and system for realizing multi-screen display. Background technique [0002] The projector is the main tool for daily meetings and sharing of multimedia resources. Commonly used projectors generally include a client display screen and a projection display screen; among them, the client display screen is generally a display window for users to perform projection operations, and the projection display screen uses the projection device of the projector to enlarge and display the same file as the client display screen content. When the user needs to display the content of other files, it is necessary to end or pause the operation of the currently displayed file content on the client display screen, and open the path of the new file content to be displayed through the client display screen to realize the new file display of content. [0003] In the above projectio...
