How to Clean LED Screens?

Keeping your valuable LED displays clean and tidy can be a challenge. You need to adopt some effective and harmless cleaning solutions to keep them running smoothly. Read on for helpful tips on cleaning LED screens without causing internal or external damage.

  1. Disconnect the power

No matter what type of LED display screens you are cleaning, the first step is to shut down the system and disconnect the power supply, then wait a few minutes for it to cool down. It will reduce the risk of electrocution and make it easier to clean the LED screen without creating annoying and unsightly streaks.

  1. Clean with microfiber cloth

The screen of an LED display is an important medium for achieving high quality image display. Using rough cloth or trying to cut dirt with nails and other tools can easily cause serious damage to the top layer or anti-gloss coating. Therefore, it is wise to use microfiber cloth rather than rough cloth to clean LED screens.

Microfiber cloth is a delicate and soft material, but strong enough to thoroughly clean your LED video displays without causing damage. Moreover, microfiber cloths will not collect or spread lint on your LED screen, and are able to trap large amounts of dirt and dust without leaving streaks because of the intricate way tiny fibers are interwoven.

  1. Use non-abrasive cleaning solutions

The best way to clean LED screens is to use non-abrasive cleaning solutions, such as isopropyl alcohol diluted with pure or distilled water. Spray the solution onto a microfiber cloth and gently wipe the LED video wall by moving it up and down or side to side.

Never clean LED screens with ammonia or alcohol-based cleaners. Ammonia and topical alcohol have the potential to cause irreversible damage to the extremely delicate anti-glare coating. Not only will this negatively impact your viewing experience, it will also make your LED display screens difficult to use in strong sunlight.

  1. Do not spray liquid cleaners directly onto the screen

Spraying liquid cleaners directly on the screen can easily corrode the LED video wall due to harsh chemicals. Besides, it is simple for liquid entering the interior to damage the internal components. A safer and smarter way to clean LED screens is to first wipe it with a dry cloth, then spray a small amount of cleaning solution onto another cloth and gently wipe the surface of the LED video wall. Wipe with a clean, dry cloth after this step to remove any residual liquid. 

  1. Vacuuming with a vacuum cleaner and compressed voids

Dust that accumulates between the seams of the LED display screen (where the bezel and top glass or plastic meet) may penetrate deeper and cause internal damage to your LED video wall. Regular use of a vacuum cleaner with a soft bristle brush can help you keep your devices clean.

As an added measure, spray the surface of your LED displays with a can of compressed air, or even the vents on the back of the unit, to blow away any lingering stubborn debris or dust. The longevity and functionality of your LED video wall will ultimately be improved by regularly using this cleaning technique.

  1. Have a professional cleaning team

For outdoor LED screens installed on building facades, a professional cleaning team is required. To avoid damaging the LED lamp beads and screen, they typically employ aerial ropes or crane boats that are outfitted with expert cleaning equipment, depending on the varied degrees of dirt.

How to Dehumidify LED Screens?

There are many indoor and outdoor applications for LED display screens, but the performance and lifespan will be negatively impacted by the humid climate during the rainy season. Therefore, effective dehumidification is necessary while maintaining LED screens.

  1. Use dehumidifiers

The recommended humidity range for an LED screen’s operating environment is 30% to 60%, with no significant humidity variations between before and after. The ideal way to dehumidify for an LED display screen working in a high-humidity environment is to utilize a dehumidifier or turn on the dehumidification mode of the air conditioner.

When there is a higher level of humidity present and there is evident water mist on the LED screen, a dehumidifier should be utilized with a fan to dry the air. The best dehumidification result is when it reaches the ideal relative humidity for LED displays.

  1. Keep distance from windows

In order to prevent the rainy season or high air humidity from constantly misting the LED displays, it is best to avoid installing an LED video wall close to a window. If the LED video wall has been installed next to a window, make sure to close the window when it is working.

  1. Utilize humidity detection tools

It is recommended to set up a hygrometer next to the LED display screen to keep an eye on humidity changes. Once the humidity has abnormal conditions, the staff on duty can take action to improve it in time.

How to Maintain Outdoor LED Screens in Bad Weather?

Maintaining outdoor LED screens will be a tough challenge as they are subject to failure from time to time due to bad weather such as heat, typhoons, rainstorm and lightning. Read on to get useful tips for maintaining outdoor LED screens in bad weather.

  1. Equip with heat dissipation equipment

Due to the large size, outdoor LED screens require a lot of power to operate, which in turn increases the amount of heat they release. If the heat dissipation issue with the LED screen cannot be resolved in a timely manner, it is likely to result in circuit short in the summer when the temperature is very high.

To aid with the equipment’s heat dissipation, LED screen manufacturers should aim to develop hollow shells and add an air conditioner or fan for their LED displays. As for business owners, you should insist on having the LED display screens installed in a place that has good air permeability. If necessary, you can additionally add heat-dissipation apparatus to the exterior.

  1. Add lightning rods and lightning protectors

Although the outdoor LED displays have excellent waterproof performance, prolonged exposure to thunderstorms can easily destroy the housing screen and lead to circuit breakers and other issues. In serious cases, it might potentially start a fire. Therefore, lightning protection for outdoor LED screens is essential.

  • Installing lightning rods and grounding wires on the support structure of the outdoor LED display screens can effectively prevent direct lightning strikes. In general, grounding resistance values must be fewer than 10 ohms; if they are higher, you must create an additional artificial grounding network.
  • Lightning current can be efficiently stopped on the power line by a single-phase or three-phase power lightning protector. It is important to note that the cross-sectional area of the phase line should be larger than 10 square millimeters and the cross-sectional area of the grounding wires should be larger than 16 square millimeters.
  • Lightning current can be efficiently stopped on a signal line with a signal lightning arrester. The system’s signal interface determines the signal lightning arrester. If the interface is a network cable, a network signal lightning arrester is installed; if it is a serial interface, a DB9 interface lightning arrester is installed. It is worth noting that the cross-sectional area of the grounding wires cannot be less than 1.5 square millimeters.LED screens installation and repair

    How Do You Take Care of LED Screens?

    It is advised to know how to take care of LED screens on a daily basis to preserve its superb image display performance, in addition to knowing the dos and don’ts of LED screens maintenance.

    If possible, you should run your LED display screens more frequently. It is recommended that you turn on LED displays at least three times every week for a minimum of two hours each time. Only turn off the power to the control device and keep the LED screen in standby mode if you won’t be using it for an extended period of time. It will significantly lower the power consumption of the device by doing so.
