Full-color LED screen can realize cluster management and unattended functions. One computer can control the operation of multiple LED screen. At this time, remote control and remote data transmission signals will be encountered. When transmitting LED screen signals over long distances, what should be paid attention to?
1. Signal transmission medium
Select a signal transmission medium suitable for long-distance transmission, such as optical fiber or high-quality coaxial cable. These media have low signal attenuation and interference, and can effectively transmit signals and maintain signal quality.
2. Signal amplifier
For longer-distance transmission, signal amplifiers or signal repeaters may be required to enhance the strength and stability of the signal. These devices can be placed in appropriate locations in the transmission line to ensure that the signal does not lose quality when transmitted over long distances.
3. Screen control system
Ensure that the screen control system has long-distance control functions so that the display content can be managed and controlled from a distance. This can be achieved through network connection, remote control software or other remote management means.
4. Signal attenuation and interference
Long-distance transmission may cause signal attenuation and interference, affecting display quality. Pay attention to the layout of the signal line and avoid being too close to interference sources (such as power lines, high-frequency equipment, etc.). In addition, the use of shielded cables and signal interference suppression technology can reduce interference and maintain signal quality.
5. Stable power supply
Ensure stable power supply for the screen and control system during long-distance transmission. Unstable power supply may cause signal interference and abnormal screen operation.
6. Signal delay
Signal delay may occur during long-distance transmission. Pay attention to the impact of signal delay on the displayed content and make appropriate corrections when necessary.
7. Testing and debugging
After completing the long-distance transmission setting, test and debug to ensure signal quality and display effect. The test includes inspections of signal integrity, color accuracy, frame rate and refresh rate.
In summary, when transmitting the signal of the full-color LED advertising screen over long distances, it is necessary to pay attention to matters such as signal transmission media, signal amplifiers, screen control systems, signal attenuation and interference, stable power supply, signal delay, and testing and debugging to ensure stable signal transmission, good quality and normal display effect.
