What is LED display sending card?

Send card Settings are very simple, if your display screen job in the form of 1024×768 do not need to be set to work, otherwise you need to select the required display form, and then click "save to send card", set your computer resolution from scratch. Today, let's analyze the sent card description of the LED display.

First, the LED display sending card description principle: the sending card is composed of DVI module, FPGA controller, and two Gigabit network output modules. The DVl decoding chip sends the decoded data and control signal to the FPGA operator, the FPGA is cached by the internal RAM, and does the operation of replacing the clock domain and bit width, and then outputs the disposed data through the Gigabit network. For the real-time video source with a resolution of 1280×1024 and a rewriting frequency of 60Hz, the method of straight partition is used here to evenly distribute the full screen data to two gigabit network outputs, and each gigabit transmission is 640X1024.

Second, LED display send card description: send card Settings are very simple, if your display screen work in the form of 1024×768 do not need to be set to work, otherwise you need to select the required display form, and then click "save to send card", set your computer resolution from scratch.

Third, LED display transmission card transmission features:

led display screen, led display lights, led display panel, led display app, led display alarm clock

1, for the write RAM operation, first store the regular data, the time is t, and then enter the waiting period (t=t1-t2 is the line cycle); For the read RAM operation, it is necessary to be satisfied with t3 when the stored data passes through the transmission

2. Storing data into RAM and retrieving data from RAM are carried out together.

3, the speed of storing RAM is fast, and the speed of reading RAM is slow.
