[0031] refer to figure 2 The flow chart of a kind of LCD multi-screen different display method shown, the method specifically comprises the following steps:

[0032] Step S201, receiving multiple frames of video frames to be played.

[0033] Wherein, each frame of the video frame to be played carries an active identifier.

[0034] Optionally, the multiple video frames to be played may be transmitted by the playing server in real time.

[0035] Wherein, multiple frames of video frames to be played can be different frames of the same continuous video, or different frames of different videos.

[0036] It should be noted that in the embodiment of the present application, different frames from different video sources are taken as examples.

[0037] Step S202, decrypt the source ID to obtain a decrypted key.

[0038] It should be understood that when the playback server sends the video frame to be played, the active identification is encrypted in the video frame to be played. ...

Abstract

The embodiment of the invention provides an LCD multi-screen different display method and system, and belongs to the technical field of display. According to the method, corresponding LCD display modules are accurately found by directly judging that a video frame to be played carries an active identifier, so that multi-screen different display is quickly and accurately realized, and different types of input interfaces do not need to be configured for each LCD display module, so that the installation complexity is greatly reduced, and the installation cost and the manufacturing cost are reduced. In addition, the LCD display modules are matched in a source identification mode, multi-screen different display can be more flexible, and the application scene is wider.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an LCD multi-screen differential display method and system. Background technique [0002] At present, there are more and more applications of splicing display, and splicing not only makes the size of the display screen larger, but also makes it effective for outdoor commercial display. [0003] However, many of the current spliced ​​displays are displayed synchronously, that is to say, the spliced ​​display screen is only used as a display screen to play, and the picture is simply enlarged. If multi-screen different display is to be realized, splicing display cannot be realized. At present, it is common to realize multi-screen different display by connecting different types of interfaces for different display screens. This causes each display screen to be limited by the input interface, and at the same time causes higher installation costs. Once the display input is...
