[0017] The LED sending card processes and converts the input image or video signal to meet the display requirements of the LED display; transmits the processed signal to the receiving card of the LED display through a specific communication protocol; can process and adjust the input signal, such as adjusting the brightness, contrast, and color to obtain the best display effect; can realize remote control and management of the LED display, such as adjusting the display content, switching the display mode, and improving the convenience of management.

[0018] Data transmission and encoding: LED sending card 101 is responsible for receiving signals or data from computers or media sources (such as video players), and transmitting these data quickly and stably to the LED display through data lines or networks (such as Gigabit Ethernet). The sending card will encode the received data to meet the display requirements of the LED display, including cutting and packaging the image or video data according to the arrangement order of the display modules of the LED display, and adding necessary control signals.

[0019] Signal synchronization and display control: For synchronous LED display screens, the sending card obtains video data from the outside through interfaces such as HDMI / DVI, and ensures that these data can be displayed on the LED screen in real time and synchronously. That is, the content displayed on the PC screen will be played on the LED screen at the same time. The sending card is also responsible for controlling the display content, playback sequence, playback speed, etc. of the LED display screen to ensure that the display screen can work according to the preset requirements.

[0020] System configuration and status monitoring: The sending card generally obtains configuration information through communication ports such as USB, such as display resolution, brightness, contrast and other parameters, so as to make corresponding adjustments and optimizations. The sending card can also report its working status in real time, such as data transmission rate, error rate, etc., to help users understand the system operation status in time and perform troubleshooting.
