Factors affecting the service life of LED display
LED full-color display screen outdoor application rapid development, gradually become the leader of outdoor advertising, gradually appear in the streets and alleys, dress up our various cities, but LED full-color display screen will also be long life, unreasonable maintenance, no longer available. So, what are the factors that determine the life of LED advertising screen? The way to cope with the symptoms is particularly important, now let's take a look at the factors that determine the life span of LED full-color display.
First, the impact of the production process on the product
The production process of LED full color display screen products determines the method of fatigue protection performance. With poor 3 kinds of anti-fatigue treatment produced by the module fatigue resistance is difficult to guarantee, if the temperature and humidity changes, the circuit board to protect the surface will be cracked, the protection performance will be reduced, so the production process of LED advertising screen is also a key factor in determining the service life of the display. Display production includes parts storage and pretreatment process, over the road welding process, 3 kinds of anti-processing process, waterproof sealing process and so on. The effect of the process is related to the rate of material selection, parameter control and staff quality, for absolutely large LED full-color display manufacturers, the accumulation of experience is very important, the control of the production process of experienced factories may be more effective.
Second, LED light source device performance impact
LED biz device is the most important and most relevant component of the advertising screen in terms of longevity. the main indexes of LED soldering channel include attenuation characteristics, water and vapor permeability characteristics, UV protection characteristics, etc. If the LED full color display manufacturer fails to evaluate the indicated performance of the LED solder channel, the application to the advertising screen will lead to major quality accidents and seriously affect the life of the LED full color display.
Third, the impact of supporting components
In addition to LED indicators, LED full-color display also uses many other accessory components, such as circuit boards, plastic enclosures, switching power supplies, connectors, disk cabinets, etc. Therefore, if any component has quality problems, the life of the screen may be shortened. Therefore, the life of the advertising screen is determined by the life of that key component with the shortest life. For example, LED, switching power supply, metal casing is selected according to the standard specification of 8 years, the performance of the circuit board's protection process can only run for 3 years, corrosion may lead to damage after 3 years, and only 1 display has a life span of 3 years.
Fourth, display the impact of the working environment
According to the use of advertising screen working conditions vary widely. Environmentally, the temperature at home is very small, no rain or snow, does not affect the ultraviolet rays. The difference in outdoor temperature is up to 70 degrees, accompanied by wind, sun and rain. The harsh environment will aggravate the aging of the display, the working environment is an important factor affecting the life of the display. In a sense, the working environment of the LED full-color display determines his life. the life of the LED is usually the luminous intensity decay to 50% of the initial value of the time period. Semiconductor material LED usually has a life of 100,000 hours, but evaluated under ideal conditions. Can not reach the actual use.
The life of the LED welding channel determines the life of the LED full-color display, it does not mean that the life of the LED welding channel is equal to the life of the advertising screen. When the advertising screen is running, not all indicators are always running at full load, if the display is playing video programs normally, the life of the LED full color display should be about 8 times of the life of the LED lamps, and if the LED beads are working at low current, the life may be longer.
