Every consumer is very hopeful that they bought the LED display can be used forever, but this is not now every electronic product has a life expectancy, LED display is no exception. Although it can not be used permanently, but we can extend the life of the LED screen through some methods. For this reason, this article will introduce you to the content of the LED screen life.
Understanding the life of the LED screens
- Economic life:Economic life means that the longer the LED display can be used, the lower the average cost.
- Technical life:The technical life refers to the period from the use of LED displays in the market to their replacement by devices with new display technologies.
- Service life:The service life is the period of time from the start of the use of the LED display to the time when the device breaks down or is damaged.
- Average lifespan:Ideally, the service life of LED display can reach 150,000 hours. However, taking into account the influence of realistic factors, the average lifespan of an LED display may be 100,000 hours.
Factors affecting the of an LED screen lifespan
Usage
The different uses of LED displays can have a great impact on their lifespan. In particular, LED displays with multiple brightness variation levels and colors will have a reduced lifespan with its use.
Because the LED display in the application if the use of more colorful, more colorful, then the more power required, the faster the energy consumption, so it will lead to the rise of the internal temperature of the LED display, which affects the normal operation of certain internal components, making the performance of the LED display decline, shortening the service life of the LED screen.
Environment
LED display life will also be affected by the surrounding environment, different environmental conditions used in the life of different lengths, the following are the three main environmental factors affecting the life of the LED display:
Temperature
LED display is divided into 2 parts: module and cabinet, LED display module mainly consists of LED lamp beads, control panel and chips and other components. These components are particularly important to the work of the LED display.
When the LED display is in a high temperature environment, the heat generated by the LED display and the heat brought by the environment, two different forms of heat will lead to a sharp rise in the temperature inside the LED display, the internal components of the LED display will be worn out, or even unable to work.
Humidity
Most of the outdoor LED display has waterproof function, for example: the circuit board inside the outdoor module is coated with three-proof paint, which can effectively protect the circuit board; the outdoor module will be installed with a waterproof rubber ring, which can play a role in blocking the effect of water flow and foreign objects, so that the internal parts and functions are protected.
However, in a high humidity environment, some components within the LED display will still be affected by moisture in the air. When moisture enters the internal components, the internal circuit board will be affected by moisture, which will lead to oxidation and corrosion of the circuit, in which the moisture will also damage the insulating material in the LED display, resulting in a short circuit of the internal circuit.
Corrosive gases
If long-term in the corrosive gas environment, such as: coastal areas, industrial manufacturing areas and energy manufacturing areas, etc., then it will accelerate the consumption of LED display life.
Coastal areas
Coastal areas of the air salinity is several times the inland, and salt on metal substances will produce a certain corrosive. When the salt-containing air soaks inside the LED display, the salt will exacerbate the conductivity of water and accelerate the process of corrosion of metal parts. Among other things, the absorption of moisture by insulating materials will also increase the material volume conductivity and dissipation factor.
Industrial manufacturing
Industrial manufacturing will produce some corrosive gases, such as HF (hydrogen fluoride), C (carbon), Cl2 (chlorine) and ClO2 (chlorine dioxide), etc., which will slowly corrode and corrode with the internal meta parts of the LED display, and in the long term, it will lead to the stoppage of the operation of the LED display.
gases produced
Most of the gases produced in the energy manufacturing area are corrosive gases, for example: petroleum manufacturing industry will produce H2S (hydrogen sulfide), SO2 (sulfur dioxide), SO3 (sulfur trioxide), etc., they will react strongly with the interior of the LED display screen to accelerate the corrosion of the internal components of the speed of the meta-equipment components, thus reducing the life of the LED display screen faster.
Dust
Although a small amount of dust may not have a great impact on the life of the LED display, however, with the passage of time, dust will continue to accumulate, forming a layer of influence on the internal LED display heat dissipation “network”, this layer of “network” will lead to the LED display internal temperature rise. This layer of “net” will cause the internal temperature of the LED display to rise, resulting in heat can not be discharged as soon as possible, to the normal work of the internal components have an impact.
Vibration and collision
All electronic equipment in the installation or transportation process are inevitably subject to vibration and collision, LED display is the same. These vibrations and collisions will have a certain impact on the life of the LED display. If the vibration and collision exceeds a certain range, it will increase the risk of damage to the LED components, thus reducing the life of the LED display.
Load
Load refers to the device that can convert electrical energy into other forms of energy, LED lamp beads in the LED display, switching power supply, etc. need to work under the rated load. When the LED display screen for a long time, its power supply will show a trend of overload, which will accelerate the aging speed of the power supply and affect the service life of the LED display.
Therefore, large LED display screen needs a special power distribution cabinet. The purpose is to distribute power to each load part, slow down the aging speed of the power supply, and provide protection against power failure when the circuit is short-circuited, overloaded, or leaking.
Component Quality
There are large and small components in the LED module, if one of them is not of good quality, then it will affect the life of the LED display.
Design structure and manufacturing process
The overall design structure and manufacturing process of LED display plays a key role in its life. The design structure and manufacturing process mainly includes storage and pretreatment, welding, moisture, dust, corrosion, waterproof sealing, heat dissipation and other processes. The effectiveness of these processes is largely determined by the choice of materials, process control and operator skills, experienced manufacturers are better able to manage these processes to extend the life of the LED display.
Ways to extend the service life of LED display
After we understand about the factors affecting the life of LED display, next, look at how to extend the life of LED display, the methods are as follows:
Provide proper ventilation
The problem of heat accumulation inside the LED display is a common cause of shortening the life of the LED display. In order to alleviate the problem of heat buildup inside the LED display, you can place the LED display in a ventilated place or install a heat sink on the LED display. If you are using the method of installing a heat sink, it is best to place it on the back of the LED display and keep the distance between the LED display and the wall at least 4 inches when installing the LED display.
Avoid places that are too humid or too sunny
LED display should avoid places that are too humid or sunny. If it is placed in a place that is too humid, then the interior of the LED display may be affected by moisture and in this way cause a short circuit. If placed in the sun, then the LED display will not bring the audience a good display effect, which will have a certain impact on the audience’s viewing experience.
Use of surge suppressors and voltage regulators
Surge suppressors can mitigate short-term voltage surges and filter electrical noise and electromagnetic interference.
Voltage regulators can provide long-term stable voltage for LED displays. Even if the voltage in the grid fluctuates greatly, it can be stabilized against voltage fluctuations.
LED display with integrated surge suppressor and voltage regulator can be subjected to comprehensive electrical protection, stable power supply, so that the LED display to reduce damage and extend the life cycle.
Perform proper closing and opening operations
Generally the manufacturer will recommend you the best way to turn on and off the LED display, for example, the PC should be turned on before starting the LED display and the LED display should be turned off before turning off the PC. If you don’t follow this way, then the LED display will be damaged over time. In addition, frequent powering off and on will exacerbate the damage to the LED display and will cause its life to decay.
Software and Firmware Updates
After a period of time, LED displays should have their software and firmware checked and updated. Software and firmware updates usually solve most problems and optimize system functions to reduce the risk of software-related problems. Their updates can extend the life of the LED display to a certain extent.
Regular maintenance and cleaning
Dust is everywhere, in order to be able to reduce the impact of dust on the LED display, we need to carry out regular maintenance and cleaning of the LED display. You can use cleaning cloth and special cleaning brush to clean the LED display. It should be noted that when you want to clean the dust inside the LED module or cabinet, remember to cut off the power supply before cleaning.
Do not use corrosive cleaning agents to clean
When you are cleaning the LED display, do not use corrosive cleaners for cleaning, for example: use cleaners containing alcohol, ammonia or chlorine, these chemicals may cause corrosion or damage to the LED display. When you are cleaning, you can use a small amount of water or a special cleaner for LED display to clean, which can safely remove dust and dirt and keep the LED display clear and undamaged, thus prolonging its service life.
Conclusion
After reading the above content about the life of LED display, we can know that there are more factors that affect the life of LED display. If we can avoid these factors, then we can make the life of LED display screen longer.
