How LED Control Card Works?

The control card can be connected to a computer via HDMI, DP, DVI, and other signal cables to transmit video signals.

Ethernet cables or USB will be connected to a computer and control card. This will send the control command to the LED display.

A LED video processor is required if you want to integrate image quality improvement, image zooming, and other special functions.

LED Control System

Synchronous
Synchronous

A synchronous LED control system is used to control and synchronize multiple LED displays. It allows for the displays to be coordinated and controlled as a single unit. Thus, creating a cohesive and seamless display.

In addition, this control system is designed for displaying real-time videos, notifications, and graphics. This makes the LED display suitable for both outdoor and indoor use. With synchronous control system, any LED screen can work at 60f/s. Therefore, contents are not limited.

Suitable working scenarios:

Asynchronous
Asynchronous

It is used to control and manage multiple LED displays independently. Thus, allowing each display to have its own unique settings and configurations. It also allows for more flexibility and customization in the display of content.

Asynchronous LED control system consists of full, double, or single-color card. Double and single color can only display texts and symbols. However, full color asynchronous LED control system allows graphic, animation and video displays.

This is also known as offline control system or offline LED card. Cable and serial ports are needed to display information. It is widely used for small LED screens to displays notices, slogans, and advertisement with short playback.

LED Control System Trouble Shooting
  • Ensure that the power supply is providing the correct voltage and that all connections are secure.
  • Check that all wires are connected properly and that there are no loose connections.
  • Verify that the LED control system is programmed correctly and that the correct commands are being sent to the LEDs.
  • Ensure that the LEDs and control system have proper ventilation.
  • Check for electromagnetic interference (EMI) or radio frequency interference (RFI) that could be affecting the control system’s performance.
  • Verify that the software is up-to-date and that all settings are configured correctly.
