How long is the service life of the led display screen_Six daily maintenance of the led display screen
About LED Display
LED display screen 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 easy to install and maintain, can be used flexibly anytime, anywhere, and is suitable for many installation conditions. So, how long is the service life of a general LED display?
The use of LED displays is divided into indoor and outdoor. Take the LED display produced by Lianchengfa as an example. Whether indoor or outdoor, the service life of the LCD module panel is more than 100,000 hours. Because the backlight is generally LED light, the backlight life of the LED screen is comparable to that of the LED screen.
Even if it is used 24 hours a day without interruption, the theoretical equivalent life is more than ten years, and the half-life is 50,000 hours. Of course, these are theoretical values! How long it can last is closely related to the use environment and maintenance of the product. Good maintenance and maintenance methods are the basis for the life of the LED display screen. Therefore, the LED display screen purchased by consumers must have quality and service as the premise.
Factors affecting the life of the led display
We all know that by using good chips and suitable materials, the service life of the available LED display is not short, at least two years. However, various problems are often encountered in the use process, especially the outdoor LED display, constantly exposed to wind and sun, and even worse weather conditions. Therefore, various problems will inevitably occur, and the appearance of such issues will inevitably affect the service life of the LED full-color display.
So what factors will affect the service life of the LED display? It is nothing more than two significant factors, internal and external factors; the internal factors include the performance of LED light-emitting devices, the performance of peripheral components, and the anti-fatigue performance of products, and the external factors include the working environment of the LED display.
LED light-emitting device
The LED light-emitting device, the LED lamp used in the display screen, is the most critical and life-related component of the display screen. For LEDs, we pay attention to the following indicators: attenuation characteristics, waterproof and vapor permeability characteristics, and UV resistance. Luminance decay is an inherent characteristic of LEDs. For a display screen with a design life of 5 years, if the brightness of the LED used is attenuated by 50% in 5 years, it is necessary to consider the reserved attenuation margin in the design. Otherwise, the display performance will not meet the standard after five years.
The stability of the attenuation index is also essential. If the attenuation has exceeded 50% in 3 years, this screen’s life will end prematurely. Therefore, when buying an LED display, it is best to choose a chip with good quality. If Nichia or Cree, etc., these significant manufacturers of professional LED chips have good quality and performance.
Display screen for outdoor use
Display screens used outdoors are often eroded by moisture in the air. When the LED light-emitting chip is exposed to water vapor, stress changes or electrochemical reactions occur, resulting in device failure. Under normal circumstances, the LED light-emitting chip is wrapped in epoxy resin and will not be corroded. Some LED devices with design or material process defects have poor sealing performance, and water vapor can easily pass through the gap between the pins or between the epoxy resin and the shell. Entering the inside of the device will cause the device to fail rapidly, which is called “dead light” in the industry.
In addition, under the irradiation of ultraviolet rays, the properties of the colloid and bracket material of the LED will change, which will cause the device to crack, thereby affecting the life of the LED. Therefore, the anti-ultraviolet ability of LEDs used outdoors is also one of the critical indicators. Thus, the waterproof treatment of LED displays used outdoors must be done well, and the protection level must reach IP65 to achieve waterproofing, dustproof, sunscreen, and other effects.
In addition to LED light-emitting devices, the display screen uses many other peripheral component materials, including circuit boards, plastic housings, switching power supplies, connectors, chassis, etc. Any problem with any component may lead to the life of the display screen. Reduce. Therefore, it is no exaggeration to say that the life of the critical element with the shortest life determines the most extended life of the LED display. Consequently, it is essential to choose a suitable material.
Fatigue resistance of display products
The fatigue resistance of display products depends on the production process. The anti-fatigue performance of the modules made by the poor three-proof treatment process is difficult to guarantee. When the temperature and humidity change, cracks will appear on the protective surface of the circuit board, resulting in a decrease in the defensive 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
Currently, LED display screens have been widely used in all walks of life, bringing a lot of convenience to people’s lives. Many companies use LED displays, and some purchase a lot, such as real estate companies, movie theaters, etc. Although the company has purchased the product, many people still do not know how to maintain and use it. Here, the editor of Lianchengfa (http://www.lcf-led.cn/) will share with you some daily maintenance of the LED display. Method, I hope it can help you.
The fixation inspection of the components inside the LED display screen.
If damaged or other problematic parts are found, they should be replaced in time, especially the tiny amounts of the steel frame structure; when receiving an early warning of natural disasters such as weather deterioration, it is necessary to check the stability and safety of each component of the screen. , If there is a problem, deal with it in time to avoid unnecessary losses; regularly maintain the surface coating of the LED display and the welding point of the steel structure to prevent corrosion, rust, and fall off; the LED display requires frequent maintenance, at least a year. Maintenance twice.
Inspection of defective products:
Regular inspections should be carried out for faulty products, timely repair or replacement, usually once every three months.
Maintenance of LED display
In the maintenance of the LED display, sometimes the LED lights need to be cleaned. When cleaning the LED light, use a soft brush to scrub the dust accumulated outside the LED light tube gently. You can dip it in water to clean it if it is a waterproof box. 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.
Fourth, the lightning protection facilities of the LED display should be checked frequently. Regularly check the lightning rod and grounding circuit; after the occurrence of lightning, the anti-pipe should be tested. If it fails, it must be replaced in time; it can be checked frequently during the rainy season.
Check the power supply system of the display screen.
First, check whether each line’s connection in the distribution box is rusted or loose. If there is any problem, it should be dealt with in time; for safety, the grounding of the electric box must be regular and checked regularly; the power lines and new signal paths should also be checked periodically. , to avoid the line being broken or bitten; the entire power supply system also needs to be inspected twice a year.
Check the LED control system.
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 should be checked regularly to avoid accidents; the system’s reliability should be checked periodically, such as once every seven days, etc.
Any product has a life cycle, and LED displays are no exception. A product’s life is related to its raw material quality and production process, and people’s daily maintenance. To prolong the service life of the LED display, we must develop the habit of maintaining the LED display in the process of use, and this habit should be deeply rooted and strictly implemented.
