LED display is a new type of display equipment, it has many advantages compared with the traditional display means, such as long service life, high brightness, fast response, visual distance, strong adaptability to the environment and so on. The humanized design makes the LED display easy to install and maintain, can be used anytime and anywhere flexibly, suitable for many installation conditions, the scene is realized and image, or energy saving and emission reduction, a kind of green environmental protection items. So, how long is the service life of the general LED display?
The use of LED display can be divided into indoor and outdoor. Take the LED display produced by Yipinglian as an example, whether indoor or outdoor, the service life of the LED module panel is more than 100,000 hours. Because the backlight is usually LED light, the life of the backlight is similar to that of the LED screen. Even if it is used 24 hours a day, the equivalent life theory is more than 10 years, with a half-life of 50,000 hours, of course, these are theoretical values! How long it actually lasts also depends on the environment and maintenance of the product. Good maintenance and maintenance means is the fundamental life system of LED display, therefore, consumers to buy LED display must have quality and service as the premise.
Factors affecting the life of led display
We all know that the use of good chips, good materials, general LED display use life is not short, at least will be used for more than two years. However, in the process of use, we often encounter various problems, especially the LED display used outdoors, often suffer from wind and sun, and even worse climate environment. Therefore, it is inevitable that there will be various problems, which will inevitably affect the service life of LED full-color display.
So what are the factors that will affect the service life of LED display? In fact, there are no more than two factors, internal and external causes of two kinds; The internal reasons are the performance of LED light-emitting devices, the performance of peripheral components, the anti-fatigue performance of the product, and the external reasons are the working environment of LED display.
LED light-emitting devices, that is, the LED lights used in the display screen, are the most critical and life-related components of the display screen. For LED, we pay attention to the following indicators: attenuation characteristics, water vapor penetration characteristics, anti-ultraviolet performance. Luminance attenuation is an inherent characteristic of leds. For a display screen with a design life of 5 years, if the brightness attenuation of the LED used is 50% in 5 years, the attenuation margin should be considered in the design, otherwise the display performance cannot reach the standard after 5 years. The stability of the decay index is also very important. If the decay exceeds 50% in 3 years, it means that the life of the screen will end prematurely. So when buying LED display, it is best to choose a good quality chip, if Riya or Kerui, these professional LED chip manufacturers, not only good quality, but also good performance.
Outdoor display is often eroded by moisture in the air, LED chip in contact with water vapor will cause stress change or electrochemical reaction leading to device failure. Under normal circumstances, the LED light-emitting chip is wrapped in epoxy resin and protected from erosion. Some LED devices with design defects or material and process defects have poor sealing performance, and water vapor easily enters the device through the gap between the pin or the gap between the epoxy resin and the shell, resulting in rapid device failure, which is called “dead lamp” in the industry.
In addition, under the ultraviolet irradiation, the colloid of LED, the material properties of the support will change, resulting in the cracking of the device, and then affect the life of LED. Therefore, the UV resistance of outdoor LED is also one of the important indicators. So the use of outdoor LED display waterproof treatment – must do a good job, protection level to reach IP65 can achieve waterproof, dust, sun protection and other effects.
In addition to LED light-emitting devices, the display screen also uses many other peripheral component materials, including circuit boards, plastic housing, switching power supply, connectors, housing, etc. Any component problems, may lead to reduced display life. So it would be fair to say that the longest life span of an LED display is determined by the life span of the shortest key component. So it is particularly important to choose a good material.
The anti-fatigue performance of display products depends on the production process. It is difficult to guarantee the anti-fatigue performance of the module made by the poor three-proof treatment process. When the temperature and humidity change, the protective surface of the circuit board will crack, leading to the deterioration of the protective performance. Therefore, the purchase of LED display should consider large manufacturers, an LED display manufacturer with many years of experience will be more effective in controlling the production process.
LED six common maintenance methods
At present, LED display has been widely used in all kinds of industry, bringing a lot of convenience to people’s life. Many enterprises will use LED display, and some enterprises purchase more, such as real estate enterprises, movie theaters and so on. Although enterprises have bought products, many people still do not know how to maintain and use them.
LED display screen body internal components of the fixed inspection. If it is found that there are damaged and other problem parts, it should be replaced in time, especially the steel frame structure of each zero small parts; When receiving the warning of natural disasters such as bad weather, it is necessary to check the stability and safety of each component of the screen body. If there is any problem, it should be dealt with in time to avoid unnecessary losses; Regularly maintain the surface coating of LED display and steel structure welding points to prevent corrosion, rust and fall off; LED displays require frequent maintenance, at least twice a year.
Inspection of defective products: for defective products to have regular inspection, timely maintenance or replacement, generally three months once.
LED display in the process of maintenance, sometimes need to clean the LED light. When cleaning the LED light, gently scrub the dust accumulated outside the LED light tube with a soft brush. If it is a waterproof box, it can also be cleaned with water. According to the use of the LED display environment, we need to carry out regular cleaning and maintenance to ensure the stable operation of the whole screen body.
LED display lightning protection facilities to check often. Check the lightning rod and ground line regularly; In the occurrence of thunder should be tested on the pipe, if failure, must be replaced in time; It can be checked frequently during periods of heavy rain.
Check the power supply system of the display panel. First of all, it is necessary to check whether the connection points of each circuit in the distribution box are rusty or loose. If there is any problem, it is necessary to deal with it in time. For safety, the grounding of the electrical box must be normal and checked regularly. New power lines and signals should also be checked regularly to avoid breaking the skin or being bitten; The entire power supply system also needs to be inspected twice a year.
LED control system inspection. On the LED control system, according to the pre-set situation a pair of its various functions are tested; All the lines and equipment of the screen should be checked regularly to avoid accidents; Check the reliability of the system regularly, such as once every seven days.
Any product has a service life cycle, LED display is no exception. The life of a product is not only related to the quality of its own raw materials and production technology, but also closely related to People’s Daily maintenance. To extend the service life of LED display, we must develop the habit of maintenance of LED display in the process of use, and this habit goes deep into the bone marrow, strictly carry on.
