The playback effect of the عرض الصمام determines the commercial value of your LED display. If the playback effect is good, many advertisers will use your display to advertise.
In the same way, if the playback effect is poor, no one will use your display whether the dead light phenomenon determines the quality of the LED display playback effect. So, how to prevent the dead light phenomenon of LED displays?
1. What are the hazards of the dead light phenomenon to LED displays?
The harm of the dead light phenomenon to LED display is really a headache. It brings a lot of problems. We have to talk about it.
You see, once the dead light appears on the LED display, the picture becomes like a pockmarked face, and the small black spots and dark spots are particularly conspicuous. The originally beautiful and clear picture is destroyed like this, and it looks very uncomfortable.
When our audience friends watch it, they will definitely feel awkward and keep muttering in their hearts: “Why is this display like this?” In this way, the viewing experience will be greatly reduced.
Let’s talk about the economic aspect. When there are too many dead lights, maintenance becomes a common occurrence. Today, you change a lamp bead, and tomorrow, you repair a line.
Money just flows out like this. Moreover, sometimes the maintenance is not timely, or the repair is not done well, and the scope of damage may become larger and larger, and more money will be spent.
For enterprises, this is a big burden. Originally, they were counting on this display screen to make some money, but now it has become a money-losing product.
In addition, the phenomenon of dead lights also affects the image of the enterprise. Think about it, if this display screen is placed in a public place or used to display the image of the enterprise, then if it has a problem, people will definitely think that this enterprise is not good and does not do things reliably.
In this way, the reputation of the enterprise will be damaged, and it will be difficult to cooperate with it in the future.
The most terrible thing is that dead lights may also bring safety hazards. Those necrotic lamp beads may heat up or short-circuit at any time. If they cause a fire or something, it will be a big deal. At that time, not only will the money be lost, but people may also be injured or even killed. This is really no joke.
So, we can’t take the dead light phenomenon of LED display light lightly. We have to choose good products, be careful when installing them, and pay more attention when using them.
We also have to check and maintain regularly and deal with problems as soon as they are found. This is the only way to ensure that the LED display screen will serve us for a long time without any problems.
Method 1: First, understand the use environment of the LED display screen
LED display screens are now everywhere: in مراكز التسوق, streets, and conference rooms. But do you know that its performance and life are actually closely related to the environment in which it is located.
If the environment is not suitable, the LED display screen is prone to dead light phenomenon, that is, some lamp beads are not bright, affecting the viewing effect. Therefore, you have to understand and choose a suitable environment so that the LED display screen can be used longer and look more comfortable.
1). Comprehensively evaluate the installation environment
1.1). Temperature check
The ideal temperature environment for LED display screen installation is between -20℃ and 45℃. Within this temperature range, it works most stably and has the longest life. If it is too hot, such as in a boiler room or steelmaking workshop, the LED lamp beads will age easily, and their lifespan will be short.
Moreover, the circuit components inside may not be able to bear it, and their performance will be reduced. It is also not good if it is too cold. The display screen may be difficult to start, or the display may not be clear. Therefore, we have to avoid installing display screens in these places.
If there is really no other way, we have to install heat dissipation equipment or heating equipment to keep the temperature within the appropriate range.
1.2). Humidity control
The ideal humidity environment for installing LED display screens is between 10% and 90%. It is uncomfortable if it is too dry or too wet.
If the humidity is too high, such as in a bathhouse or swimming pool, condensation may occur inside the display screen, the circuit may short-circuit, and the lamp beads may be corroded.
If the humidity is too low, there may be a lot of static electricity, which is not good for the circuit. Therefore, we have to avoid installing display screens in these places.
If there is really no other way, we have to install dehumidification equipment or use moisture-proof agents to keep the humidity within the appropriate range.
1.3). Dust management
Dust is the enemy of LED display screens. Too much dust will cause poor heat dissipation of the lamp beads, high temperature, and easy aging of the lamp beads.
Moreover, dust may block the light, making the display screen unclear. Therefore, we have to clean the display screen regularly. Use a soft cloth and mild detergent to wipe it gently.
Never use liquid to wash the LED module directly, otherwise the lamp beads will be broken. It is best to make a cleaning plan and find someone to clean it regularly so that the display screen can be kept clean and fresh.
2). Avoid extreme installation environments
2.1). High-temperature environment
We should not install display screens in places with continuous high temperatures such as boiler rooms and steelmaking workshops. The temperature there has long exceeded the tolerance range of the display screen.
If there is really no way to install it, then we have to find a way to cool it down. Install cooling fans, air conditioning equipment, or simply buy a high-temperature resistant display screen. In this way, the display screen can work steadily in a high-temperature environment.
2.2). High humidity environment
It is best not to install the display screen in places with continuous high humidity, such as bathhouses, swimming pools, and beaches. The humidity there has long exceeded the tolerance range of the display screen.
If you really have no choice, you have to find a way to prevent moisture. You can install a dehumidifier, use a moisture-proof agent, or simply buy a display screen with good moisture-proof performance.
In this way, the display screen can remain dry and clear even in a high humidity environment.
2.3). Strong direct sunlight
In places like outdoor unobstructed squares and balconies, where the sun shines directly, the surface temperature of the display screen is high, and the lamp beads are prone to aging.
If you really have no choice, you have to find a way to block the sun. You can install a sunshade or a sunshade, or simply buy a display screen with a sun protection function. In this way, the display screen can remain cool and clear outdoors.
2.4). Places susceptible to physical impact
Places where people come and go are easy to touch the display screen. Once touched, the display screen may be broken, or the light may die. If you really have no choice, we have to find a way to protect the display screen.
You can install a protective cover or anti-collision strip or simply buy a display screen with strong impact resistance. In this way, the display screen can work safely in places that are susceptible to physical impact.
In short, when you choose the installation environment of the LED display screen, you must pay attention to indicators such as temperature, humidity, and dust, and avoid extreme environments.
In addition, it is also important to clean the display screen regularly, check the circuit connection, and use the power supply reasonably. When buying a display screen, you must choose a brand and product with reliable quality and good after-sales service. When installing and using it, you must follow the instructions and operating procedures.
Method 2: Correctly install the LED display screen and correctly connect the wires
1). It is best to ask professional installers
Installing an LED display screen is not a job you can do by tinkering at home. You have to find experienced professionals who are like magicians who can install your display screen step by step according to the instructions.
They know how to choose a site, how to fix the bracket, how to install the screen, and can help you debug it to ensure that everything runs normally.
Moreover, they will help you check the on-site environment, such as whether the wall is flat and whether the load-bearing capacity is sufficient, so as to avoid those hidden small problems from becoming big troubles in the future.
2). Wiring according to the installation specifications
Wiring is a technical job; just like playing a game of connecting lines, you have to connect the power cord and the signal cord to the right place. The power cord must be distinguished by the positive and negative poles and don’t connect them in reverse.
Otherwise, it will be like the battery is installed in the wrong direction; not only will the display screen not light up, but it may also burn the equipment.
The signal cable must also be plugged into the right interface; don’t plug it in the wrong way; otherwise, it will be like the TV antenna is not connected properly, and the picture will be blurry.
When connecting, remember to tighten the terminal; don’t let it loose. Otherwise, it will fall off while walking, just like the shoe laces are not tied properly, resulting in an unstable signal.
In addition, the direction and fixation of the cable are also very important; don’t let them be pulled or stepped on. Otherwise, the core will break or the outer skin will be damaged, which will be troublesome.
Method 3: Reasonable use of the power supply of the LED display
The LED display has very high requirements for power supply, and must have a stable and reliable مزود الطاقة to support its normal operation. There cannot be a little fluctuation.
Therefore, when we provide power to the display, we must ensure that the voltage is stable and the fluctuation range is within the range that the display can withstand. Don’t be greedy and buy inferior products.
At the same time, the capacity of the power supply must be large enough to meet the power requirements of the display to avoid equipment damage caused by overload operation.
To achieve this goal, we can choose power supply equipment with reliable quality and regularly inspect and maintain the power supply line to ensure the stability and reliability of the power supply.
In addition, a fuse or leakage protector must be added to the power supply line, just like putting a layer of armor on the display. The fuse is like a gatekeeper. If the current is large, it will stop it from entering to prevent the equipment from burning out.
When choosing a fuse, choose the appropriate specification according to the power and current of the equipment, not too large or too small. The leakage protector is like a caring bodyguard. If the equipment leaks electricity, it will immediately cut off the power supply to protect your safety.
Also, don’t forget to protect against lightning strikes, especially in areas prone to lightning. It’s like holding up a big umbrella for the display screen, so you don’t have to worry about thunderstorms.
Method 4: Do a good job of static protection for LED display screens
Static electricity is an invisible killer for LED display screens, and it can harm the display screen silently. Therefore, the frame and metal parts of the display screen must be grounded, just like installing a lightning rod for the house.
In this way, static electricity can flow into the earth along the ground wire and will not remain on the display screen to cause damage. When grounding the wire, choose a thicker copper wire with good contact, and don’t let it break or lose.
Also, check the ground wire regularly to see if it is intact, and don’t let it become a decoration.
When you touch the LED display screen, you have to be as elegant and careful as a gentleman. It’s best to wear anti-static clothes, shoes and gloves.
Anti-static clothes and shoes can reduce the static electricity generated on your body, and gloves can directly isolate the contact between static electricity and the display screen.
If you don’t have gloves, you can also touch other metal objects first, such as door handles, faucets, etc., to discharge the static electricity on your body before touching the display screen.
Also, don’t touch the display screen in a too-dry environment; just like don’t sunbathe in the desert, dryness makes it easy to generate static electricity. You can put a humidifier or sprinkle some water to increase the humidity and keep the environment moist.
Method 5: Regularly clean and maintain the LED display screen
Dust and dirt, these two seemingly insignificant “little devils,” are actually the “natural enemies” of LED displays.
They land silently on the surface of the screen, not only blocking the light and making the displayed content unclear but also gradually eroding the surface of the screen, destroying its protective layer and eventually causing the dead light phenomenon.
Therefore, it is crucial to give the LED display screen a “big clean” regularly.
When cleaning, you must first choose a soft cloth, such as a microfiber cloth, which has fine fibers and will not scratch the surface of the screen. Then, dip it in a little mild detergent.
Note that the detergent must be non-corrosive and non-irritating to avoid secondary damage to the screen. Then, wipe the surface of the display screen gently and evenly, just like treating a precious work of art, to thoroughly remove dirt and ensure that the screen is not damaged.
During the wiping process, follow the order from top to bottom and from left to right to avoid missing any corners. At the same time, the force should be moderate, and don’t use too much force like wiping a table. Otherwise, it may scratch the screen and leave scratches that are difficult to repair.
Also pay attention to the power cord and signal line. They are the “lifeline” of the LED display, and their integrity is directly related to the normal operation of the display. Therefore, regularly checking the connection of these lines is a task that we cannot ignore.
When checking the power cord, you should carefully check whether the outer skin of the wire is damaged, aged or cracked, which may cause the inside of the wire to be exposed, causing safety hazards such as short circuit or electric shock.
At the same time, check whether the connector of the power cord is firm, loose or in poor contact. If any problems are found, they should be replaced or repaired immediately to ensure the safety and reliability of the power cord.
For the signal line, you should also carefully check whether its connection is firm and whether the plug is firmly inserted without loosening or falling off.
In addition, pay attention to the direction and fixation of the signal line to prevent it from being stepped on, pulled, or squeezed, resulting in the breakage of the wire core or damage to the outer skin.
Once a problem is found in the signal line, a professional should be contacted as soon as possible to repair it to avoid affecting the normal operation of the display.
Just like we have a physical examination every year, LED display screens also need to be “checked” regularly to ensure that they are always in the best condition.
Routine testing can include multiple aspects, such as testing of performance indicators such as brightness, chromaticity, uniformity, refresh rate, and troubleshooting of abnormal phenomena such as dead lights, bright spots, and dark spots.
When conducting routine testing, you can use professional testing instruments or software to conduct a comprehensive scan and analysis of the display screen. Once any abnormality or performance indicator is found to be substandard, it should be recorded immediately and contacted in time for repair by professionals.
In this way, you can ensure that the display screen is always in the best condition and presents the clearest and most gorgeous visual effects to the audience.
Method 6: Control the use time and brightness of the LED display
1). Use the time reasonably and let the display “rest.”
People need to rest, and machines also need to “rest.” Long-term continuous use of the LED display will cause a lot of heat to its internal components, accelerate the aging process, and thus shorten the service life.
Therefore, you need to arrange the use time reasonably and let the display “rest” appropriately.
Specifically, you can make a reasonable “work and rest schedule” according to the frequency and occasion of the display. For example, on occasions such as commercial advertisements or conference presentations, you can set a timer switch to automatically turn off the display when not in use.
On occasions such as stage performances that require long-term continuous use, you can arrange the interval time appropriately to allow the display to “respite.” In this way, you can save energy and extend the service life of the display.
2). Adjust the سطوع to make the display “comfortable.”
Brightness is an important performance indicator of LED display, but too high brightness will not only cause energy waste, but also may cause stimulation and damage to the audience’s vision.
While too low brightness will affect the clarity and visibility of the display effect. Therefore, we need to adjust the brightness of the display according to the ambient light.
Specifically, when the light is strong during the day, you can increase the brightness of the display to ensure that the displayed content is clearly visible.
At night or when the light is weak, you can lower the brightness to avoid visual stimulation to the audience. At the same time, you can also flexibly adjust the brightness according to the importance and urgency of the displayed content.
For example, when playing important notifications or emergency information, you can increase the brightness appropriately to attract the attention of the audience; when playing general content or background images, you can reduce the brightness appropriately to save energy and protect the display.
خاتمة
In short, it is not difficult to prevent the LED display from dying.
As long as you can treat it carefully, find professionals when installing, be careful when wiring, choose a good power supply, be careful and thoughtful when doing electrostatic protection, clean and maintain regularly, and reasonably control the use time and brightness, you can keep the LED display in a very good state!
I hope you can keep these tips in mind and use them in actual operations, so that our LED display can serve us more stably and lastingly.
