Problems solved by technology

[0007] 2. If multiple asynchronous full-color controllers are used, and each asynchronous full-color controller controls multiple receiving cards, it will face additional computers or switches, and the control cost will be greatly increased
[0008] 3. The number of mirror screens is limited by the number of network ports available on the switch or the number of computers
[0009] 4. Strictly speaking, the solution of adding a computer to a switch cannot achieve absolute synchronous playback

Embodiment Construction

[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] like Figure 5 As shown, it is an LED mirror screen display device of the present invention, which includes multiple asynchronous full-color controllers and multiple LED screens connected in series in the same number, wherein the asynchronous full-color controllers and multiple LED screens are alternately arranged one by one. That is, one LED screen is connected in series between every two asynchronous full-color controllers...

Abstract

The invention provides an LED mirror screen display method and device. The device comprises a plurality of asynchronous full-color controllers and a plurality of LED screens, the asynchronous full-color controllers and the LED screens are connected in series, the number of the asynchronous full-color controllers is the same, and the asynchronous full-color controllers and the LED screens are alternately arranged one by one. Wherein each asynchronous full-color controller is provided with three network ports, the three network ports comprise a computer private network port and two common network ports, and the computer private network port is connected with a computer end. And each LED screen comprises a plurality of receiving cards which are connected in series. The mirror screen effect can be realized without a switch and a plurality of computers, so that the scheme cost is saved; the method does not need to consider the problem of synchronous control of multiple computers because parameters and commands can be directly forwarded; according to the method, the situation of non-synchronization does not exist, almost no delay forwarding exists, and the synchronism is higher than thatof joint control of multiple computers.

Description

technical field [0001] The invention relates to the technical field of LED asynchronous full-color control, in particular to an LED mirror screen display method and device. Background technique [0002] like figure 1 As shown, the existing asynchronous control system of the LED display usually consists of an asynchronous full-color controller and an LED screen. The sending device mainly refers to the asynchronous full-color controller, and the display data of the asynchronous full-color controller mainly comes from a computer or a video processor including a sending function, SD card, USB, etc. The asynchronous full-color controller is mainly responsible for decoding the input video source and sending it to the receiving card. LED screen is mainly composed of LED screen and receiving card, such as figure 2 shown. The receiving card is mainly responsible for receiving the command parameters and display data sent by the sending device, and outputting the display data to t...
