How to maintain full-color LED display in daily use?

I. Precautions for switching LED electronic display screen: Switching sequence: When switching on the screen, switch on the screen first, and then switch on the screen. ? When closing the screen: close the screen first, then turn it off?

Turn off the computer without turning off the display screen, which will cause the screen to highlight and burn out the lamp tube, with serious consequences. )

The interval between screen switching should be more than 5 minutes. ?

After entering the engineering control software, the computer can be turned on. ?

Avoid opening the screen in the state of full white screen, because the impact current of the system is the largest at this time. ?

Avoid opening the screen when it is out of control, because the impact current of the system is the largest at this time. ? A, the computer did not input control software and other programs; ? The computer is not powered on; ? C. the power supply of the control part is not turned on. ?

When the ambient temperature is too high or the heat dissipation condition is not good, you should be careful not to turn on the screen for a long time. ?

When one line of the electronic display screen is very bright, attention should be paid to closing the screen in time, and it is not appropriate to screen for a long time in this state. ?

The power switch of the display screen often trips, so it is necessary to check the screen body or replace the power switch in time. ?

Check the firmness of the hook regularly. If there is looseness, pay attention to timely adjustment, re-reinforce or update the hanger. ?

According to the environmental conditions of the screen body and control part of the large-screen display screen, avoid insect bites and place rodenticide if necessary. ?

Second, the problem of broken screen

In order to avoid possible problems, we can choose passive protection and active protection. Passive protection means that users in some public places such as Internet cafes and dormitories can choose to buy tempered glass monitors, which will make your display "impeccable", but it will affect the color of the display and reflect light. Active protection means to be more careful in normal use, try to keep things that may harm the screen away from the screen, and try to wipe it lightly when cleaning the screen to minimize the possibility of injury.

Third, the use of environmental considerations.

The working environment temperature range is -20℃≤t≤50℃, and the working environment humidity range is 10% to 90% RH；;

Avoid using or storing in high temperature, high humidity and high acid/alkali/salt environment;

Keep away from flammable materials, gases and dust;

Avoid strong collision and sharp object collision during transportation;

When the ambient temperature is too high or the heat dissipation condition is not good, be careful not to turn on the screen for a long time;

When the humidity of LED display screen exceeds the specified level, it will lead to corrosion or even short circuit of parts, resulting in permanent damage.

Water, iron powder and other easily conductive metal objects are strictly prohibited in the screen. The LED display screen should be placed in a low dust environment as much as possible. Large dust will affect the display effect, and too much dust will damage the circuit. If water enters for various reasons, please turn off the power immediately and use it after all the components in the screen are dry.

Fourth, cleaning precautions

Regular cleaning and maintenance: large LED full-color display screen is exposed to outdoor environment for a long time, exposed to wind, rain and sun. Even if the indoor LED display screen is used for a long time, more traces of dust and rain will accumulate on the screen, which needs to be cleaned regularly and timely to prevent the viewing effect from being affected.

If cleaning the surface of the module, gently brush it with a soft brush. Do not use any liquid substance to clean the surface of LED module, otherwise it may damage LED lamp beads;

Correct wiping: The large screen surface of LED display screen can be wiped with alcohol, or dusted with brush and vacuum cleaner, but not directly wiped with wet cloth.

Five, moistureproof and storage requirements

Storage temperature requirements: the ambient temperature is -40℃≤t≤60℃. After the package is opened, the LED products must be stored at this temperature.

According to the environmental conditions of the display and control part, insect bites should be avoided, and rodenticide should be placed if necessary.

The LED display cannot be turned off for a long time. In a high humidity environment, if the screen body is not used for more than 3 days, it needs to be preheated and lit every time: the brightness of 30%-50% is preheated for 4-8 hours, and then the screen body is turned to normal brightness (80%- 100%), so that the moisture can be removed and there is no abnormality during use; If the screen body is not used for more than 7 days, the preheating lighting method should be adopted every time the screen body is lit: the brightness of 30%-50% is preheated 12 hours or more, and then it is adjusted to the normal brightness (80%- 100%) to light the screen body, so that moisture can be eliminated and there is no abnormality in use.
