Precautions and daily maintenance for using LED display screens

With the widespread use of LED displays, Accompanying this is an increasing number of usage issues. In order to better use LED display related products, we have made some feasible summaries on the relevant usage precautions and daily maintenance.



Precautions for use environment

1. The working environment temperature range of led display is -20 ℃ ≤ --- ≤ 50 ℃, and the working environment humidity range is 10% to 90% RH;

2. Avoid using or storing of led display in high temperature, high humidity, high acid/alkali/salt environments;

3. Keep away from flammable materials, gases, and dust for use of led display;

4. Avoid strong collisions and sharp objects during transportation of led display;

5.When the ambient temperature is too high or the heat dissipation conditions are poor, attention should be paid not to use the led display screen for a long time;

6.LED display screens with humidity exceeding the specified limit can cause component corrosion, even short circuits, and permanent damage when powered on;

7. It is strictly prohibited to let water, iron powder, and other conductive metal objects enter the screen body. LED display screens should be placed in a low dust environment as much as possible. Large dust can affect the display effect, and excessive dust can damage the circuit. If water enters due to various reasons, please immediately turn off the power until all components inside the screen are dry before use.

Precautions for switching on/off screens

1. LED display screen opening: First, turn on the control computer to run normally, and then turn on the LED display screen;

2. Screen shutdown: First, turn off the power supply of the LED screen, then turn off the control software, and finally turn off the computer; (Turning off the computer first and then turning off the LED display screen can cause high bright spots on the screen, burn out the lamp tube, and have serious consequences)

3. The time interval between turning on and off the screen should be greater than 2 minutes;

4. Avoid turning on the computer screen when it is in full white, as the full white screen is in its maximum power state and has the greatest impact current on the entire power distribution system.



Power supply precautions

1. The LED module is powered by DC+5V (working voltage: 4.2-5.2V), and AC power supply is prohibited; The positive and negative terminals of the power terminal must not be reversed (note: once reversed, it will burn out the product and even cause serious fires);

2. Power supply voltage for LED display screen: 110V-220V ± 10% Frequency: 50HZ ± 5%;

3. Ensure reliable contact with the ground, reliable isolation between the ground wire and neutral wire, and keep the power supply away from high-power backup when connected;

4.If abnormal phenomena such as short circuit, tripping, wire burning, smoking, etc. are found, the power test should not be repeated. The problem should be promptly identified and the manufacturer's after-sales customer service should be contacted;

5. Keep the power supply stable and provide grounding protection to avoid lightning strikes. Do not use it in harsh natural conditions, especially during strong lightning weather;

6. It is necessary to supply power to the large screen step by step, as the maximum power state of the entire screen will have an impact on the entire distribution system;

7. LED display screens are prohibited from playing full white images with the highest brightness for more than half an hour, in order to avoid excessive current, power cord heating, LED bead damage, and affecting the service life of the display screen. It is recommend to mainly play dynamic videos or pictures.

8.During the use of LED display products, the power cannot be turned on or off continuously, and there should be at least 2 minutes between the two operations;

9. The internal wiring of LED display screens should not be touched by non professionals to avoid electric shock or damage to the wiring; If there is a problem, please have a professional perform maintenance.


Moisture proof and storage requirements

1. Storage temperature requirements: The ambient temperature is -40 ℃ ≤ --- ≤ 60 ℃. After opening the packaging, LED products must be stored in an environment with a temperature<30 ℃ and humidity<60%;

2. According to the environmental conditions of the display screen body and control part, avoid insect bites, and if necessary, place anti rodent drugs;

3. LED display screens cannot be turned off for a long time. In high humidity environments, if the screen has not been used for more than 7 days, a preheating lighting method should be used each time the screen is lit up: preheat the screen to a brightness of 30% -50% for 4-8 hours, then adjust it to normal brightness (80% -100%) and light up the screen to eliminate moisture and ensure that there are no abnormalities during use; If the screen has not been used for more than 15 days, a preheating lighting method should be used each time the screen is lit: preheat the brightness of 30% -50% for more than 12 hours, then adjust it to normal brightness (80% -100%) and light up the screen to eliminate moisture and ensure that there are no abnormalities during use.
