How long is the life of the led display & the six daily maintenance of the led display

　　How long is the life of the led display

　　LED display is a new type of display device. Compared with traditional display methods, it has many advantages, such as long service life, high brightness, fast response speed, long visual distance, and strong environmental adaptability. The humanized design makes the LED display screen easy to install and maintain, can be used flexibly anytime and anywhere, suitable for many installation conditions, and the realized scenery is also a harmonious image, and it is also a kind of energy-saving, emission-reducing, and environmentally friendly item. So, how long is the service life of a general LED display?

      The use of LED display is divided into indoor and outdoor. Take the LED display produced by Lianchengfa as an example. Whether it is indoor or outdoor, the service life of LCD module panel is more than 100,000 hours. Because the backlight is generally LED light, the backlight The life span is equivalent to that of the LED screen. Even if it is used 24 hours a day without interruption, the equivalent life expectancy is more than 10 years, and the half-life is 50,000 hours. Of course, these are theoretical values! The actual use time is also closely related to the use environment and maintenance of the product. Good maintenance and maintenance methods are the foundation of the life system of the LED display. Therefore, the LED display purchased by the consumer must have quality and service as the premise.

　　Factors affecting the life of led display

　　We all know that using good chips and good materials, the service life of general LED displays is not short, at least two years or more. However, in the course of use, various problems are often encountered, especially the LED display used outdoors, which is often exposed to wind and sun, and even worse climatic environment. Therefore, various problems will inevitably occur, and the occurrence of such problems will inevitably affect the service life of the LED full-color display.

　　So what are the factors that will affect the life of the LED display? In fact, there are two major factors, internal and external; internal factors include the performance of LED light-emitting devices, the performance of peripheral components, and the anti-fatigue performance of the product, and the external factors include the working environment of the 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 LEDs, we pay attention to the following indicators: attenuation characteristics, water vapor permeability characteristics, and UV resistance. Brightness attenuation is an inherent characteristic of LEDs. For a display 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 reserved in the design, otherwise the display performance will not reach the standard after 5 years; the stability of the attenuation index is also It is very important that if the attenuation has exceeded 50% in 3 years, it means that the life of this screen has ended early. Therefore, when buying an LED display, it is best to choose a good quality chip. If Nichia or Cree, a major manufacturer of professional LED chips, not only has good quality, but also good performance. 

　　 Outdoor display screens are often corroded by moisture in the air. When the LED light-emitting chip is exposed to water vapor, it will cause stress changes or an electrochemical reaction will cause the device to fail. Under normal circumstances, the LED light-emitting chip is wrapped in epoxy resin and will not be corroded. Some LED devices with design defects or material and process defects have poor sealing performance, and water vapor can easily pass through the pin gap or the gap between the epoxy resin and the shell joint surface. It enters the inside of the device and causes the device to fail quickly, which is called a "dead light" in the industry.

　　 In addition, under the irradiation of ultraviolet light, the properties of the colloid and the support material of the LED will change, which will cause the device to crack and affect the life of the LED. Therefore, the anti-ultraviolet resistance of LEDs used outdoors is also one of the important indicators. Therefore, the waterproof treatment of the LED display used outdoors must be done well, and the protection level must reach IP65 to achieve the effects of waterproof, dustproof and sun protection.

       In addition to LED light-emitting devices, the display also uses many other peripheral component materials, including circuit boards, plastic casings, switching power supplies, connectors, casings, etc. Any problem with any component may lead to the life of the display. reduce. Therefore, it is no exaggeration to say that the longest life of the LED display is determined by the life of the key component with the shortest life. Therefore, it is particularly important to choose a good material.

　　 The fatigue resistance of display products depends on the production process. It is difficult to guarantee the fatigue resistance of modules made by poor three-proof processing technology. When the temperature and humidity changes, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the protective performance. Therefore, large manufacturers should be considered when purchasing LED displays. An LED display manufacturer with many years of experience will be more effective in controlling the production process.

　　 Six daily maintenance of LED display

　　 At present, LED displays have been widely used in all walks of life, bringing a lot of convenience to people's lives. Many companies will use LED displays, and some companies purchase more, such as real estate companies and movie theaters. Although the company has purchased the product, many people still don’t know how to maintain and use it. Here, the editor of Lianchengfa (http://www.lcf-led.cn/) will share with you some of the daily maintenance of LED displays. Method, hope to help everyone.

　　 1. The fixity inspection of the internal components of the LED display screen. If you find any defective parts such as damage, you must replace them in time, especially the small parts of the steel frame structure; when you receive warnings of natural disasters such as weather deterioration, you need to check the stability and safety of the various components of the screen. If there is a problem, deal with it in time to avoid unnecessary loss; regularly maintain the surface coating of the LED display and the welding point of the steel structure to prevent corrosion, rust and peeling; the LED display requires frequent maintenance, at least a year Maintenance twice.

　　 2. Inspection of defective products: Regular inspection of defective products should be carried out in a timely manner, usually once every three months.

　　 3. In the process of maintenance of the LED display, sometimes the LED lights need to be cleaned. When cleaning the LED lamp, use a soft brush to gently scrub the dust accumulated on the outside of the LED tube. If it is a waterproof box, you can also dip it in water for cleaning. According to the use environment of the LED display, we need to clean it regularly Maintenance to ensure the stable operation of the entire screen.

　　 4. the lightning protection facilities of the LED display should be checked frequently. Check the lightning rod and the grounding circuit regularly; after the lightning strikes, the anti-pipe should be tested, if it fails, it must be replaced in time; it can be checked frequently during periods of heavy rain.

　　 5. Check the power supply system of the display screen. First, check whether the connection of each line in the distribution box is rusty or loose. If there is a problem, it should be dealt with in time; for safety, the grounding of the electrical box must be normal and checked regularly; the power line and new signal circuit should also be checked regularly , To avoid the line being broken or bitten; the entire power supply system also needs to be inspected twice a year.

　　 6. LED control system inspection. On the LED control system, each function is tested one by one according to the preset conditions; all the lines and equipment of the screen must be checked regularly to avoid accidents; the reliability of the system is checked regularly , Such as once every 7 days.

　　 Any product has a life cycle, and LED displays are no exception. The life of a product is not only related to its own raw material quality and production process, but also closely related to people's daily maintenance. To extend the service life of the LED display, we must develop the habit of maintaining the LED display during the use process, and this habit should be deeply rooted and implemented strictly.
