With the continuous innovation and improvement of LED technology, the application of full color LED displays is becoming increasingly widespread in various industries, such as exhibition halls, business halls, conference halls, shopping malls, hotels, brand stores, and other occasions. Here, some customers may not have a good understanding of the basic knowledge of full color LED display. Let’s analyze together:
1、 Normal switch on/off of full color LED display screen
- Switching sequence: A. First turn on the control computer to ensure its normal operation, and then turn on the full color LED display screen; B. Turn off the full color LED display screen first, and then turn off the computer. (Turning off the computer first without turning off the large screen can cause high highlights on the screen, which may burn out the lamp beads over time)
- After the computer enters the engineering control software, the screen can only be opened and powered on, and the time interval between opening and closing the screen should be greater than 5 minutes.
- Avoid opening the screen in a fully white screen state, as the system’s impulse current is high at this time.
- Avoid opening the screen in a state of loss of control (A. the computer has not entered control software or other programs; B. the computer is not powered on; C. the power supply of the control part is not turned on), as the system’s impact current is high at this time.
- When the ambient temperature is too high or the heat dissipation conditions are not good, attention should be paid not to open the screen for a long time.
When a very bright line appears on a part of the electronic display screen, attention should be paid to turning off the screen in a timely manner. In this state, it is not advisable to turn on the screen for a long time, and the manufacturer should be consulted promptly for solutions.
- If the power switch of the display screen trips frequently, the screen body should be checked or the power switch should be replaced in a timely manner.
2、 Daily usage of full color LED display screens
- Regularly check the firmness of the hanging parts, and if there is any looseness, pay attention to timely adjustment, re reinforcement or updating of the hanging parts.
- Regularly inspect the circuit and switch, keep the switch dry, and avoid leakage and electric shock accidents.
- Air conditioning can be used to dehumidify the room, place desiccants, and physically absorb moisture to keep it dry and prevent the display screen from getting damp.
- During the rainy season, it is recommended to use it at least once a week and turn it on for at least 2 hours each time.
- Moderate indoor ventilation can quickly evaporate the water vapor attached to the display screen and reduce the humidity of the indoor environment.
- If not used for a long time, it should be regularly powered on for maintenance and debugging; If it is not used for a long time, there may be dead lights and blind spots when it is used again, so it is necessary to regularly power on and light up the screen for debugging.
3、 Precautions for changes and changes to the control part of the full color LED display screen
- The power lines of the computer and control parts should not be connected in reverse, and should be strictly inserted in the original position. If there are peripherals, after connecting them, the casing should be tested for power.
- When moving control equipment such as computers, the connection wires and control boards should be checked for looseness before power on.
- The position and length of communication lines and flat connecting wires cannot be changed arbitrarily.
- If any abnormal phenomena such as short circuit, tripping, wire burning, smoke, etc. are found after movement, the power test should not be repeated, and the problem should be promptly identified
- Control the usage time. It is recommended to rest for more than 2 hours every day. Generally, the screen should be turned on at least once a month and lit for more than 2 hours
- Control the screen current, and do not stay in all white, all red, all green, and all blue bright screens for a long time during playback to avoid excessive current and excessive heating of the power cord, which may damage the LED lights and affect the lifespan of the display screen.
