[0031] refer to figure 2 Shown is a flow chart of an LCD multi-screen different display method, the method specifically includes the following steps:

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

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

[0034] Optionally, the multi-frame to-be-played video frames may be transmitted in real time by the playback server.

[0035] The multi-frame video frames to be played may be different frames of the same continuous video, or may be different frames of different videos.

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

[0037] Step S202: Decrypt the source identifier to obtain a decrypted key.

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

Abstract

The embodiments of the present application provide an LCD multi-screen different display method and an LCD multi-screen different display system, which belong to the technical field of display. The present application directly finds the corresponding LCD display module by judging that the video frame to be played carries the active logo, so as to realize multi-screen different display quickly and accurately, and there is no need to configure different types of input interfaces for each LCD display module. The complexity of the installation is reduced, the installation cost and the manufacturing cost are reduced. In addition, the present application matches the LCD display module by means of source identification, which can make the multi-screen different display more flexible and applicable to a wider range of scenarios.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an LCD multi-screen different 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 enables it to be effectively used in outdoor commercial displays. [0003] However, many of the current splicing displays are synchronously displayed, that is, the spliced ​​display screen is only used as a display screen for playback, and the screen is simply enlarged. If you want to achieve multi-screen different display, splicing display cannot be achieved. At present, it is common to realize multi-screen different display by connecting different types of interfaces for different display screens. This results in that each display screen is limited by the input interface, and at the same time, the installation cost is high. Once th...
